AI Visibility Audit is an open-source, self-hosted tool from Syntropic (legal entity VECTORLENS Sp. z o.o.), a Poland-based ecommerce-AI agency, that checks whether ChatGPT, Gemini and Google's AI Overviews and AI Mode recommend a brand, or a named competitor, for real buyer questions like "best running shoes for flat feet" or "where to buy an espresso machine under $500." It ships as a Docker Compose stack a buyer runs on their own infrastructure and turns the results into a client-ready PDF report: which competitor gets recommended instead, which buyer queries the brand is invisible for, and what to fix first.

## Verdict

The only tool in this index that frames AI visibility as recommendation share for specific buyer queries, "best X for Y", "where to buy Z", and packages the result as a client-ready PDF, rather than continuous brand-mention monitoring. It is free, fully open source, and built by a real, checkable operator (Syntropic / VECTORLENS Sp. z o.o.) with genuine release-signing hygiene rare at its size. The honest catches: without a paid Bright Data account only Google AI Overview is tracked (ChatGPT, Gemini and Google AI Mode all sit behind it), there is no Claude or Perplexity coverage, and it is a young, single-maintainer, near-zero-traction project (5 GitHub stars, two Show HN posts that together drew 3 points). Pick it for an agency pitch deck or a self-hosted, buyer-query-framed audit; choose a hosted platform with broader engine coverage if Claude/Perplexity or zero-setup matter more.

## How it works

1. Point the tool at a store or brand domain; Gemini and Exa auto-generate the realistic buyer questions shoppers ask about the category and discover the named competitors worth tracking.
2. It fires those buyer questions at ChatGPT, Gemini and Google AI Mode through Bright Data's scraping API, and at Google AI Overview through DataForSEO, recording which store gets named, recommended or cited in each answer.
3. A dashboard breaks results down by topic, by prompt trend over time, and by competitor share, with a sentiment pass scoring how the brand is framed when it is mentioned.
4. Everything rolls into a printable, client-ready PDF with a prioritized list of what to fix first — or explore the whole flow first with the built-in one-click sample dataset and zero API keys.

## Who it's for

- Ecommerce and DTC brands (or any company) that want a client-ready, one-time or recurring AI-visibility audit as a free, self-hosted, open-source Docker stack.
- Agencies that want a concrete pre-sales asset — a PDF showing a prospective client which named competitor AI recommends instead of them.
- Teams comfortable running their own Gemini/Exa/DataForSEO/(optionally) Bright Data keys who want to evaluate the format first using the built-in zero-key sample dataset.

## Strengths and weaknesses

- ✓ Built by a real, named, independently verifiable operator, Syntropic / VECTORLENS Sp. z o.o., a Poland-registered ecommerce-AI agency with a public team page, phone number and KRS/NIP registration, not an anonymous side project.
- ✓ Free and fully open source (AGPL-3.0) with genuine supply-chain hygiene for its size: cosign-signed release images, an SBOM and build-provenance attestation, and an unprivileged container user.
- ✓ Ships a one-click sample dataset, so the entire dashboard and PDF report can be evaluated with zero API keys before committing to a real audit.
- ✗ Near-zero community traction: 6 GitHub stars, 0 forks, and two separate Show HN launches a day apart (2026-06-23 and 2026-06-24) that together drew 3 points and 3 comments.
- ✗ A real functional gate, not just a nice-to-have: without a paid Bright Data account, ChatGPT, Gemini and Google AI Mode are NOT tracked at all — only Google AI Overview via DataForSEO works out of the box.
- ✗ Requires Docker plus up to 4 separate third-party API accounts (Gemini, Exa, DataForSEO, Bright Data) — real setup friction next to a hosted SaaS's zero-install signup.
- ✗ A young, single-maintainer project: first commit 2026-06-10 (about 5 weeks old at review), with one engineer (Kamil Bidus) behind 17 of roughly 20 commits.
- ⚠ No Claude or Perplexity coverage, two AI engines several rival visibility tools in this index do track are absent here.
- ⚠ No hosted or managed option; self-hosted via Docker only, so the buyer owns uptime, updates and any API cost overages.

## Key features

- **Buyer-query recommendation audit** — Sends real "best X for Y" / "where to buy Z" buyer questions to ChatGPT, Gemini and Google AI Mode (via Bright Data) plus Google AI Overview (via DataForSEO), and records which store gets named, recommended or cited.
- **Client-ready PDF report** — Exports a stakeholder-ready PDF: KPIs, competitor share, the buyer queries you're missing, and a prioritized fix list.
- **Auto-generated prompts + competitor discovery** — Gemini and Exa generate the realistic buyer questions for a category and discover the named competitors worth tracking, rather than requiring a hand-written prompt list.
- **Sentiment and source-citation tracking** — Scores how a brand is framed when it IS mentioned, and records which domains the AI cites as sources, not just a binary named/not-named check.
- **Zero-key sample dataset** — A built-in sample dataset loads in one click, so the full dashboard and PDF report can be explored before wiring up any of the 4 required API keys.

## Use cases

- **Agency pre-sales / competitive pitch** — An agency runs a free audit against a prospective client's store to show, with a PDF, which named competitor AI recommends instead of them, a concrete lead-gen asset.
- **Ongoing self-hosted visibility monitoring** — An in-house growth team self-hosts the stack and re-runs the audit on a schedule to track whether new content or PR moves AI-recommendation share, without a per-seat SaaS subscription.
- **Zero-key evaluation before committing** — A buyer loads the built-in sample dataset first to confirm the dashboard and report format are worth the 4-API-key setup investment before spending anything.
