Glimpsa
Privacy-first · bring your own key

Every page explained.
Every claim checked.

Select any text — or right-click an image, link, table or email — and the answer streams in right where you're reading. Then tap Verify and Glimpsa fact-checks its own answer against live sources. Dock the sidebar for whole pages, screenshots and PDFs.

How it works

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.

  1. 01

    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 — nothing more.

  2. 02

    The answer streams in place

    Explain a term, summarize a passage, translate it, draft a reply — right beside what you're reading. No new tab, no copy-paste, no losing your place.

  3. 03

    Verify & go deeper

    Ask follow-ups in the same popover, upgrade to a stronger model, or tap Verify to re-check every claim against live sources.

The difference

Answers you can actually check.

Generic assistants generate. Glimpsa verifies. Tap Verify and the answer is re-checked against live web sources — claim by claim — each one scored and linked to its source. 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, running on your key, with no platform lock-in. Not wired into 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.

FAQ

Questions, answered.

Do I need an API key?

Not to start — the first few asks work with no key and no sign-up. Sign in and you get free managed asks every day. For unlimited free use, paste your own Anthropic key in the extension's Options.

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?

Subscriptions are billed through Paddle; cancel anytime and you keep access until the period ends.

Can I get a refund?

Yes — within 14 days of purchase, for any reason, no questions asked. Request it from the receipt in your Paddle confirmation email, at paddle.net, or just email us. Full details in our Refund Policy.
