Free tools built to be useful, not a lead magnet.

Every tool here is free, runs in your browser, and asks for nothing — no signup, no email capture, no server call collecting your data. The first one exists because a citation test run July 21, 2026 found that promise-only claims got cited 0/5 times across ChatGPT, Gemini, and Perplexity, versus 3/6 for claims backed by a live, checkable link — so we built a way for any business to run that same check on themselves.

AI Citation Checker

A free, self-serve worksheet that checks whether ChatGPT, Claude, Gemini, and Perplexity actually mention and recommend a business by name. Built after a competitive audit of enterprise AEO services found a gap in accessible citation tracking — agencies charge $6,000+/mo for what this does for free.

More free tools are on the way. This library grows as new ones get built — each one held to the same standard as everything else here: no signup wall, no data collection, and a live link behind every claim it makes.

All tool and research links open in a new tab.

Questions about the free tools

Is the AI Citation Checker really free?

Yes. No signup, no email capture, no trial that converts to a bill later. It's a free, self-serve worksheet, the same as every other tool that will appear on this page.

Why doesn't the tool call the AI APIs directly?

It's a guided worksheet: you copy the suggested prompts into ChatGPT, Claude, Gemini, and Perplexity yourself and record what comes back. Nothing about your business is sent to a ZenMasterWorks server, and there's no API bill hiding behind the free label.

Will more free tools be added here?

Yes. This page is a living library, not a one-off — new tools get added as they're built, each held to the same no-signup, no-server-call standard.
