Khint vs Rewind,intentional, not ambient.
Rewind records everything. Khint only sees the text you select, when you press the shortcut.
Twelve capabilities,
two memory models.
Capture, storage, AI access, MCP, pricing. The honest side-by-side.
What gets remembered.
Khint: what you put in
Start a work session. Add entries explicitly (notes, OCR captures, action outputs). Khint compacts that into a short context that gets injected into your AI prompts. Stop the session and that context goes idle. No screen, no audio, no keystroke trail.
Rewind: what it captures
Continuous recording of every window you see and (opt-in) every meeting you join. Stored locally, encrypted, and queryable via Rewind AI. The pitch is total recall: you don't have to remember to remember; everything is captured by default.
Cost: €9.99/mo vs $20/mo.
Khint Premium is €9.99/month for unlimited AI actions. The free tier covers 10 AI actions/day plus 5 OCR captures/day. Rewind Mac is $20/month for the always-on capture and Rewind AI features, with a trial up front. If you need ambient capture, Khint is not the right tool. If you don't, you save the difference and get a free tier on top.
When to pick Rewind.
Rewind is the better tool when the value is total recall: "what was that link in the Slack thread three weeks ago", "show me the slide a teammate flashed at 14:02 yesterday", "play back the meeting I missed and ask questions about it". If your work depends on retrieving something that already happened on your screen, Rewind is built for that. Khint cannot retrieve what it never saw.
Common questions.
Does Khint record my screen?
No. Khint never records the screen ambiently. The only time pixels are read is when you trigger OCR from the palette: that's a one-shot capture, and the screenshot is not stored after text is extracted. There is no continuous recording, no audio capture, and no keystroke logging.
Is Khint always-on like Rewind?
No. Khint is action-driven, not always-on. Rewind's pitch is total recall: it records every window and every meeting, then lets you rewind through your day. Khint's pitch is the opposite: only the text you select is processed, and only when you press the shortcut. The Memory pillar adds your active work session's compact context into AI prompts, but it does not record your screen or your audio.
Where is my data stored?
Locally first. Your Khint history, your Packs, and your Memory sessions live in a SQLite file on your Mac. If you sign in, those records also sync to a Supabase Postgres database, encrypted at rest, reachable only via our service key. Nothing leaves the device unless you sign in or trigger an AI Action that calls the Claude API.
Can Khint search across all my activity?
No, and that's by design. Rewind is built for that: it indexes everything you see and hear. Khint only knows about what you put into a Memory session, plus your action history. If you want a passive total-recall search, Rewind is a better fit. If you want a clean, intentional record of work sessions you explicitly start and stop, Khint fits better.
Does Khint sell my data?
No. Khint does not sell user data and our cloud inference provider's API terms prohibit training on customer inputs and outputs. We don't run any fine-tunes ourselves. Sub-processors are Anthropic (Claude API), Clerk (auth), Supabase (sync), Stripe (billing), and DigitalOcean (hosting). The privacy policy lists them all.
Memory that only sees what you choose.
Compact context window injection: the active work session's summary is prepended to every AI action prompt. Free, no always-on capture, ever.
