AI at your cursor. And in your sidebar.

One gesture. An answer.
No tab-switching, no copy-paste. Glimpsa reads the context under your cursor and only ever calls the model when you tap an action.
Select or right-click
Highlight a phrase, or right-click an image, link, table, or email. A small chip appears with the actions that fit what you picked.
Explain · Summarize · Translate
Explain a term, summarize a passage, translate into your language, identify an image, draft a reply, extract a table — context-aware, every time.
Follow up & go deeper
Ask follow-ups in the same popover, upgrade any answer to a stronger model, copy it, or drop a drafted reply straight into Gmail.
Answers you can check.
Generic assistants generate. Glimpsa can verify. Tap Verify and the answer is re-checked against live web sources — claim by claim — and marked ✓ Supported, ⚠ Unverified, or ✗ Contradicted, each with a source link. It's the trust layer a horizontal tool won't build.
Privacy-first
Bring your own Anthropic key and content goes straight from your browser to Anthropic — there's no backend in the loop. On managed plans we proxy the request but never store your prompts or answers.
Model-agnostic
Built on Claude, your key, no platform lock-in. Not wired to any one browser vendor's ecosystem.
Calm by default
The chip only appears on selection or right-click. Nothing leaves your machine until you tap an action. Disable it per-site whenever you like.

- Is my content private?
- With your own key, content goes straight to Anthropic and never reaches us. On managed plans we relay the request to Anthropic but never store your prompts or answers — we count requests, not text. See our Privacy Policy.
- What's the verification layer?
- A one-tap re-check of an answer against live web sources, scored claim by claim with links — so you can trust what you act on.
- How do I cancel?
