See the retrieval layer
Capture web-search queries explicitly surfaced by ChatGPT, Claude and Google Search in a local side-panel trace.
Open-source Chrome extension
See the queries behind AI search.
Open Queries shows the web-search queries surfaced by ChatGPT, Claude and Google AI Overviews in a local Chrome side panel—and estimates likely fan-out queries only when you ask.

The open retrieval layer
Useful to inspect. Rigorous enough to audit.
Open Queries keeps direct observations and probabilistic estimates separate from capture through aggregation.
Estimate with native evidence
Request plausible fan-outs ranked by each provider’s own token probabilities—or repeated native samples when logprobs are unavailable.
Audit the whole system
Extension, Worker, schemas and methodology are public under AGPL-3.0-or-later. No black-box ranking layer.
A narrow data contract
Transparent without surveillance.
- No chat messages, titles, account identity or conversation URLs
- Query contribution is separate, optional and off until you choose it
- Sensitive-pattern filtering runs locally and at the Worker edge
- Public aggregates require at least five anonymous donors
- Estimated fan-outs never enter observed-query aggregates
Open methodology
Read the evidence, not the marketing.
