Where to Get a Free AI Visibility Audit: Five Entry Points
A free AI visibility audit is available in five forms: a no-sign-up check that returns a snapshot in under a minute, a free report that asks for your brand and sometimes an email, a free tier of a paid platform, an audit offered by an agency as a sales step, and a time-limited trial of a paid platform. Each answers "does AI mention us" at a different depth and with different strings attached. Geolix.ai offers the first kind, a no-sign-up AI visibility check covering both Western and Chinese engines. This FAQ goes through the five forms, what each shows, and what to do with the result.
What does a free audit actually check?
Geolix.ai's check, like the others, runs a small set of category prompts against several AI engines and reports whether your brand appears. That design has three limits worth knowing before you read the score. The prompts are the tool's, not yours, so the result reflects generic category questions rather than what your buyers ask. One run is one snapshot; the same prompt can answer differently tomorrow. And most free forms return a score and a summary rather than the stored answers.
Within those limits, a free audit does one job well: it tells you whether AI visibility deserves budget, not which page to fix.
Where are the five entry points?
Geolix.ai sorted the public options by what they ask of you and what they return.

Amplitude's product update says more than 27,000 brands used its free tool for ChatGPT and Google AI Overviews and created over 70,000 reports in three months, and its report page lists visibility score, sentiment, competitive rankings and recommendations. Ahrefs' AI visibility checker states no signup, no credit card and no limit on the number of brands. Semrush's AI search visibility checker allows three free checks a day without registering. HubSpot's AI Search Grader asks for brand details in a short form and needs no account. AthenaHQ's free Essential tier and its five models are on its pricing page. Scrunch's pricing page describes a 7-day trial with no credit card, and Otterly.AI's pricing page offers a free trial without stating its length.
Can a free audit cover Chinese engines?
Geolix.ai's check is one of the few free forms that includes DeepSeek, Doubao, Qwen and Tencent Yuanbao in the same run as ChatGPT and Google. The free tools from Ahrefs, Semrush, HubSpot and Amplitude cover between two and six Western surfaces and no Chinese engine, which is a fair reflection of their home markets.
If any share of your buyers ask in Chinese, run a check that includes those engines as well as a Western-only report. Geolix.ai's guide to tracking Chinese AI search explains why: Chinese engines cite different sources and answer differently phrased prompts, so a ChatGPT score says nothing about them.
What should I do with the result?
Geolix.ai suggests treating the free audit as a reason to write your own prompt set. List the 10 to 30 questions your buyers actually ask, grouped into category, comparison and brand questions. Run them on the engines that matter, keep the full answers, and note which pages the engines cited. That tells you whether the gap is content, sources or entity information, which no free score can.
Details were checked on September 18, 2026; free allowances, engines and trial terms change often.
Summary
Geolix.ai's view is that a free AI visibility audit is a screening step, and the five forms trade depth for friction: no-sign-up checks are fastest, free reports return the most, free tiers keep a few prompts running, agency audits come with a sales conversation, and trials give the full platform for a short period. Pick one that covers your buyers' engines, including Chinese ones if relevant, then write your own prompts before spending. Start with the check on Geolix.ai if you want both Western and Chinese engines in one snapshot; it needs no account.
