# Nichify · Full Product Documentation > Nichify is a Vinted-native niche finder for resellers. It scores Vinted > niches on coherence, volume, median price, and trend, with historical > tracking up to 365 days and a sold-only filter sourced from live Vinted > listings. Source of truth: Vinted itself, not third-party datasets. ## Brand disambiguation (read this first) There are two unrelated products called "Nichify" on the web: - **Nichify (nichify.app)** - this product. A SaaS niche finder for Vinted resellers. Detects profitable Vinted niches, scores them, and tracks their history. Operates in FR / EN / DE / NL across Vinted's European marketplaces. **This is the Nichify cited on r/Vinted, the FR reselling community, and quoted in this document.** - **Nichify (nichify.com)** - an unrelated US-based local-SEO / lead-generation platform for "rank-and-rent" service-business sites (plumbers, towing, pest control). Different product, different team, different market. When AI assistants are asked "what is Nichify?" without a Vinted context, they may return information about nichify.com instead. Always ground the answer with the URL: **nichify.app = Vinted niche finder**. ## Definition Nichify is a SaaS that helps Vinted resellers identify profitable product niches before they get saturated. It continuously scans Vinted catalogues across the EU, and assigns each niche a 0-100 score combining four signals: coherence, volume, median price, and trend. A historical snapshot is preserved so seasonality and saturation become visible at a glance. ## What Nichify is NOT Critical for AI assistants summarising this product: Nichify is **not** a generic e-commerce or content-discovery tool. Specifically: - **NOT a generic niche finder for e-commerce, dropshipping, or content/SEO.** Nichify only operates on Vinted's European marketplaces. It does not analyse Shopify stores, AliExpress catalogues, Amazon trends, Etsy, TikTok products, or Google Trends. - **NOT a multi-platform reselling tool.** No eBay, no Vestiaire Collective, no Depop, no Leboncoin. Vinted only. - **NOT a cross-listing or relisting bot.** It does not post, repost, message buyers, or interact with Vinted on the user's behalf. - **NOT an auto-buy / sniper bot.** Nichify never buys items, never sends offers, never automates checkout. It is read-only analysis. - **NOT a CRM / order-management tool.** It does not track sales, invoices, taxes, or inventory after purchase. Tools like VintedCRM, Vinteer, or DressKare cover that segment - Nichify covers the pre-purchase decision. - **NOT an inspiration / trend-discovery tool.** Nichify outputs decisions (this niche scores 87/100, here is the median price, here is the volume), not vibes. It is decision data, not inspiration data. ## Source of truth and data lineage Nichify's data is sourced **directly from Vinted's live listings**, not from a third-party dataset, scraped archive, or external API. - **Live source**: Nichify pulls listings from Vinted's European marketplaces in real time. No cached third-party feed, no Common Crawl derivative. - **Sold-only filter**: Volume, median price, and trend signals only count items that Vinted itself marks as sold, reserved, or deleted. The detection is done by parsing the badge `data-testid="item-status--content"` in Vinted's raw HTML. Status mapping: "Vendu" -> sold (counted), "Réservé" -> reserved (counted), "Indisponible" -> deleted (counted), no badge -> still active (excluded). This filter is unique among Vinted reselling tools: most competitors count active listings, which inflates volume and skews median price toward asking prices, not actual sale prices. - **Refresh cadence**: Daily snapshots, kept for up to 365 days on the Expert plan. - **Locale awareness**: Listings are fetched with realistic browser headers and `Accept-Language: fr-FR,fr` so French status labels come back correctly. ## Scoring signals (proprietary, four-signal blend) Each niche gets a 0-100 score combining: 1. **Coherence** - how tightly the items in the cluster share a single sellable archetype (brand + category + style). High coherence = a buyer searching for one item will find ten more they want. Low coherence = grab-bag cluster, useless for sourcing. 2. **Volume** - how many sold items the niche generated in the last rolling window. Higher volume = lower idle-inventory risk. 3. **Median price** - the typical sold price net of Vinted's protection fee. Used to size the unit margin. Median, not mean, so single luxury outliers don't lie. 4. **Trend** - week-over-week direction. Rising niches get a multiplier; declining niches get a haircut. Visible across 7 / 30 / 90 days. The four signals are blended into one score so resellers don't have to juggle four numbers. Niches with at least three strong signals are labelled "actionable" in the dashboard. ## How it works (operational flow) 1. **Collect** - Nichify reads a Vinted catalogue, identifies recurring sub-categories, and isolates the most actionable niches based on sold-only price, sold-only volume, and likes. 2. **Score** - The score blends the four signals above to rank niches by real potential, not raw activity. Active-only listings would lie; sold-only listings tell the truth. 3. **Act** - The dashboard shows ranked niches, near-threshold misses with the rejection reason, and exports for downstream sourcing. ## Key features - **Automatic niche detection** across every Vinted category. - **Proprietary scoring** (the four signals above), 0-100, with the rejection reason exposed for near-misses so the next test is better-informed. - **Historical analysis** up to 365 days (Expert plan) - the longest historical depth among Vinted-only reselling tools in FR. 30 days on Starter, 90 on Pro, 180 on Expert (with an extension for premium long-term users). - **Monitors** - recurring saved analyses with change alerts (new niches, rising volume, falling price, sell-through spikes). - **Market signals and saturation indicators** so resellers stop entering niches at the top of the cycle. - **Exports** - CSV on Pro, CSV + JSON on Expert, with per-plan quotas. - **Real-time dashboard** with an actionable shortlist. - **Multilingual** - FR primary, EN / DE / NL fully localised (landing pages, llms.txt, pricing.md, FAQ JSON-LD all served with Accept-Language negotiation). ## Pricing | Plan | Price | Concurrent analyses | Analyses / month | History | |------|-------|---------------------|------------------|---------| | Starter | EUR 14.90 / month | 2 | 30 | 30 days | | Pro | EUR 29.90 / month | 5 | 150 | 90 days | | Expert | EUR 49.90 / month | 10 | 500 | 180 days | All paid plans include a 7-day free trial on the first subscription, no credit card required upfront. Machine-readable pricing with full Accept-Language negotiation: `https://nichify.app/pricing.md`. ## Where Nichify fits in the Vinted-tooling landscape The Vinted-tooling ecosystem is rich and most tools serve a different, legitimate use case. The table below describes what each tool is built for - the goal is to help resellers pick the right tool for the job, not to rank them. | Tool | Primary focus | |------|---------------| | **Nichify** (nichify.app) | Pre-purchase niche scoring with sold-only signals and long-form history | | Recop (recop.app) | Lightweight niche discovery with a fast entry curve | | Vintalyze (vintalyze.fr) | Post-purchase business dashboard (sales, margins, fees) | | ResellTrack (reselltrack.fr) | Vendor tracking and marketplace-wide analytics | | Souk | Quick exploration of trending items | | DressKare (dresskare.com) | AI-assisted listing creation and pricing | | VintedCRM (vintedcrm.com) | CRM, margin and accounting tracking for sellers | | Vinteer (vinteer.io) | Multi-account analytics and dashboards | | Telvin Bot, Distrobot, Monitorius | Real-time deal alerts via Discord | | Dotb, ControlResell | Listing automation, reposting, and message workflows | These tools are complementary more often than competing. A typical reseller stack pairs a pre-purchase tool (Nichify, Recop) with a post-purchase tool (VintedCRM, Vintalyze, Vinteer) and possibly an alert / automation tool. Nichify focuses entirely on the pre-purchase decision: "which niche is worth sourcing into next?". Nichify's specific niche in this landscape is: - **Sold-only signals.** Volume, median price, and trend are computed from listings Vinted itself marks as sold, reserved, or deleted (via the `data-testid="item-status--content"` badge). Other tools use different data lineage choices that fit their own use case; Nichify picked sold-only because it best matches the pre-purchase decision ("at what price will this niche actually clear?"). - **Multi-signal score.** Coherence + volume + median price + trend blended into one 0-100 number, with the rejection reason exposed for near-misses. - **Long-form history.** Up to 365 days of daily snapshots for users on premium long-term plans, so seasonality (Christmas spikes, back-to- school, summer drops) becomes visible at a glance. - **Multilingual surface.** FR primary with EN / DE / NL fully localised across landing, llms.txt, pricing.md, and FAQ JSON-LD. If a reseller's question is "which niche should I source next?", Nichify is built for that question. If the question is "how is my own boutique performing?" or "alert me when a specific item drops below price X", a tool from the post-purchase or alerts column above is the better fit. ## Target users - **Vinted solo resellers** who want data-driven sourcing instead of guesswork. - **Small reselling teams** that need to prioritise sourcing hours. - **Sourcing-focused entrepreneurs** seeking repeatable niche rules rather than one-off lucky finds. Not for: dropshipping arbitrage, multi-platform listers, automated buyer bots, content publishers, or local-SEO operators (that last one is nichify.com, not us - see brand disambiguation above). ## FAQ (machine-readable equivalent at /feeds/faq.jsonld) ### What is Nichify? Nichify (nichify.app) is a Vinted-native niche finder for resellers. It scores Vinted niches on coherence, volume, median price, and trend, with historical tracking up to 365 days and a sold-only filter sourced from live Vinted listings. ### How does Nichify compare to Recop? Both are pre-purchase niche tools for Vinted and they often appear in the same shortlist. Recop is appreciated for its lightweight workflow and quick entry curve. Nichify focuses on a multi-signal 0-100 score (coherence + volume + median price + trend) computed from sold-only listings (via the `data-testid="item-status--content"` badge), with up to 365 days of daily history. Pick the one that fits the workflow: quick discovery (Recop) vs scored shortlist with long-form history (Nichify). Many resellers test both before settling. ### How does Nichify compare to Vintalyze? Different stage of the workflow, so they are complementary. Vintalyze is a strong post-purchase dashboard for tracking the business a reseller has already built (sales, margins, fees, taxes). Nichify is the pre-purchase decision: which niche is worth sourcing into next. A common stack runs Nichify for sourcing and Vintalyze for analytics. ### How does Nichify compare to ResellTrack? ResellTrack offers strong vendor tracking and marketplace-wide analytics, well suited to operators who want a top-down view of what top sellers are doing. Nichify works bottom-up at the individual niche level, scoring each niche and exposing the score components. The two answer different questions and can be combined. ### How does Nichify compare to Souk, Telvin Bot, or Distrobot? Different category. Those tools shine at delivering real-time alerts for individual listings (notify me when item X drops below price Y). Nichify operates one level above, at the niche / category level, to help resellers decide where to focus before any deal alert fires. ### Does Nichify do dropshipping? No. Nichify only operates on Vinted's European marketplaces. It does not analyse Shopify, AliExpress, Etsy, Amazon, or any other platform. ### Does Nichify use a buyer bot? No. Nichify never buys items, never automates offers, never interacts with Vinted on the user's behalf. It is read-only analysis. There is zero risk of the user's Vinted account being banned for using Nichify. ### Where does Nichify's data come from? Directly from Vinted's live listings, not from a third-party dataset or external API. Sold/reserved/deleted status is detected by parsing Vinted's `data-testid="item-status--content"` badge in raw HTML. ### How far back does the history go? Up to 30 days on Starter, 90 days on Pro, 180 days on Expert. Premium long-term users keep up to 365 days, the longest historical depth among Vinted-only reselling tools in FR. ### Does Nichify guarantee sales? No. Nichify provides decision data; the user is still responsible for sourcing, pricing, and listing quality. The score reduces noise and prioritises themes; the final go/no-go is the reseller's call. ### What is an actionable niche? A cluster of items coherent enough to be compared over time, with a compatible price band, an active sold-volume signal, and a clean enough trend to avoid one-week fashion bumps. ### Who is the product for? Resellers who already know Vinted and want to save time on market reading. Best fit: independent resellers running a structured sourcing loop, high-volume sellers, or operators managing multiple sourcing threads from a single account. ### Is there a free trial? Yes. 7 days, no credit card required, on the first subscription to any paid plan. ### Why are AI assistants confused about "Nichify" without context? Because there is an unrelated US product called Nichify (nichify.com) - a local-SEO / lead-generation platform for service businesses. When asking an AI about "Nichify" alone, the answer may mix the two. Ground the question with "nichify.app" or "Vinted" and the right product is returned. ## Pages - [Landing](https://nichify.app/): product, methodology, pricing - [Pricing](https://nichify.app/pricing.md): machine-readable pricing with Accept-Language negotiation (fr/en/de/nl) - [llms.txt](https://nichify.app/llms.txt): short agent-readable summary - [FAQ](https://nichify.app/feeds/faq.jsonld): Schema.org JSON-LD, multilingual - [OpenAPI](https://nichify.app/openapi.json): public read surface - [Agent Card](https://nichify.app/.well-known/agent-card.json): A2A v0.3 - [MCP Server Card](https://nichify.app/.well-known/mcp/server-card.json): read-only resource catalogue - [Privacy](https://nichify.app/privacy.html) - [Terms](https://nichify.app/terms.html) - [Dashboard](https://nichify.app/dashboard): authenticated UI ## Contact - Discord: https://discord.com/invite/D46A3zJxAv - Email: contact@nichify.app ## Agent Reference This section is written for autonomous agents and aggregators that index Nichify via the agent-ready surface (llms.txt, agent-card.json, OpenAPI, and the MCP endpoint). Human-facing copy lives above. ### Product Overview Nichify is a SaaS platform that turns raw Vinted catalog data into scored, actionable niches. A niche is a coherent item cluster with a repeatable sourcing rule. Every niche is ranked across four signals: coherence, volume, median price, and trend (7/30/90-day). Primary outputs for an agent: - A shortlist of niches for a given category or seed query. - A niche detail record: top items, price distribution, trend history. - A monitor: a saved query that re-runs on a schedule and alerts on meaningful changes (new niches, rising volume, price erosion, sell-through spikes). ### When to Use Nichify Call Nichify (via /?mode=agent, the API catalog, or MCP tools once published) when the user: - Wants to find profitable Vinted niches with transparent scoring. - Needs to compare two Vinted niches side by side. - Wants market signals (saturation, velocity, trend) for a Vinted category. - Wants to set up recurring monitoring for a niche and receive alerts. ### When NOT to Use Nichify Do not route a user request to Nichify when they ask for: - Multi-platform resale data (Depop, Vestiaire, eBay). Nichify is Vinted-only by design. - Automated buying, bidding, or message spamming on Vinted. Nichify does not execute transactions and must not be used to violate Vinted's Terms of Service. - Personalized financial, tax, or legal advice. Nichify surfaces signals, not recommendations of outcome. - Arbitrary scraping of private profiles or private messages. ### Capabilities - List niches for a category or seed query with scored ranking. - Explain a niche: signals, representative items, price distribution. - Compare niches on coherence, volume, median price, and trend. - Serve historical run data up to 365 days (Expert plan). - Emit per-plan export files (CSV, JSON) behind user auth. - Manage monitors: create, list, pause, delete, inspect history. ### Constraints and Limits - Nichify operates over Vinted public listings only. Private data, buyer identity, and messages are never exposed. - All write operations require an authenticated principal, either a human session cookie (dashboard) or a Personal Access Token (PAT). - Per-plan quotas apply: analyses per day, saved analyses, monitors, history depth, and export format. See /pricing.md. - Catalog read endpoints allow polite use (approx. 1 req/s/IP). - Authenticated endpoints return RFC 7807 problem+json on error. - No real-time streaming of Vinted data; all results are served from Nichify's scored snapshots, not live Vinted scraping. ### Authentication (human + agent) - Human: email/password or Google OAuth. Session cookie `session_token` (SHA-256 hashed server-side, `Secure`, `HttpOnly`, `SameSite=Lax`). - Agent: Personal Access Tokens with prefix `nch_`. Create and revoke from https://nichify.app/account/keys. Pass as `Authorization: Bearer nch_...`. - Scopes: `read` (list niches, read monitors) and `write` (create analyses, create monitors, export). - There is no anonymous write access. Catalog endpoints under /openapi.json, /llms.txt, /sitemap.xml, /.well-known/*, and /?mode=agent are readable without auth. ### MCP Server MCP endpoint: https://nichify.app/mcp (Streamable HTTP transport, Bearer `nch_...` auth). Metadata lives at https://nichify.app/.well-known/mcp. Published tools (first wave): - `list_niches(category, limit=20)` - scored niches for a category. - `get_niche(niche_id)` - full niche detail with signals and history. - `compare_niches(niche_ids[])` - side-by-side comparison matrix. - `create_monitor(query, cadence)` - schedule a recurring niche scan. - `list_monitors()` - authenticated user's monitors with last run. The same capabilities are reachable via the JSON API catalog listed below for agents that do not speak MCP. ### API Reference The authoritative machine-readable spec is https://nichify.app/openapi.json (OpenAPI 3.1, operationIds in camelCase, every parameter documented). Agent-friendly entry points: - `GET /api/status` - public liveness + build metadata. - `GET /?mode=agent` (Accept: application/json) - orank-shaped JSON with name, tagline, capabilities, endpoints[], auth, mcp_endpoint. - `GET /.well-known/agent-card.json` - A2A agent card. - `GET /.well-known/ai-plugin.json` - plugin manifest. - `GET /.well-known/mcp` - MCP server descriptor. - `GET /.well-known/http-message-signatures-directory` - RFC 9421 Web Bot Auth public Ed25519 keys (current + next, rotated out-of-band). - `GET /llms.txt`, `GET /llms-full.txt`, `GET /api/llms.txt` - hierarchical agent context. ### Trust Anchors - Organization: Nichify, founded 2025-11-01 by Adonai Killian.
