Where the free tools stop

A check is a photograph. Tracking is the film.

Every tool here answers one question once. They will tell you whether you are in the answer today — not whether you were last Tuesday, not what moved, and not why. That is the paid product, and it starts at $89 a month with unlimited seats.

The ZeroRank Overview, the tracking the free tools stop short of: visibility per brand over the last seven days, the brands ranked beside it with sentiment and rank, and the domains cited underneath.
No signup, no catch

What the free tools actually do

Seven of them run in the browser and ask for nothing. The eighth asks for a domain and an email, because it has to send you a report.

Everything you're wondering

Or ask us anything at hello@zerorank.ai

Are these really free?

Yes, and no signup. The AI brand visibility report asks for a domain and an email so we can send it to you; nothing else asks for anything.

How accurate is a one-off check?

It is accurate for the moment it ran. Answers shift with phrasing, session and day, so a single check tells you whether you are in the answer today — not whether you were last week. That is what the tracking product is for.

Which models do the free tools use?

The brand visibility report samples ChatGPT, Claude, Perplexity and Gemini. The paid product tracks 17 platforms, including ChatGPT Search and GPT-5 Search, Google AI Overviews and AI Mode, Copilot, Grok, DeepSeek, Qwen, Llama, Brave Leo, Naver, Baidu and DuckDuckGo.

Can I use the output in a client pitch?

Please do. Screenshot it, export it, put it in the deck. If you want it white-labelled and updating weekly, that is the paid plan.

Will the crawler inspector change my site?

No. It fetches your pages the way an AI crawler would and shows you what comes back. It never writes anything.

Do I need to add a script to my site?

No. Nothing here needs a tag, a plugin or DNS access. The AI referral check reads Google Analytics, read-only, and only if you connect it.
