Khint vs Rewind,intentional, not ambient

Rewind records everything. Khint only sees the text you select, when you press the shortcut.

The Rewind alternative for people who want an intentional memory. Khint is shortcut-triggered, never always-on.

Sprint 24
Runs on your session

Everything it knows is on this screen

The session on the left is the whole memory: seven entries, each one added by hand or written by a run you triggered. Watch a line of the update land and the entry it came from lights up. Nothing is selected, nothing was recorded, and there's no eighth entry you can't see.

A session you start,
not a tape that never stops

Khint's memory is a work session you open and close by hand. It holds the entries you put in, compacts them, and hands that summary to your next prompt. All of it stays in a SQLite file on your Mac.

Nothing arrives on its own

Every entry got there because you added a note, dropped a file, pulled a ticket or ran an agent. There's no background writer, and the list is short enough to read in one glance for exactly that reason.

Off until you press a key

The privacy default isn't a setting buried in a pane, it's the shape of the product: no key press, no run. Stop the session and its context goes idle without deleting anything.

It lives in a file on your Mac

Sessions, their entries and the Knowledge index are local and stay local. Signing in syncs your Packs and the metadata of your history; the bodies of what you ran never leave the device.

Your AI client reads the session, not your screen

Khint ships a standalone MCP server over stdio. Claude Desktop and Codex get the session you chose to keep, and nothing else: four ways to read it, one to append to it, and a notification every time they do.

What Khint never sees

Rewind's whole product is the feature Khint refuses to build, so this is the honest half of the comparison: what's off by default, what is never on at all, and the bill on each side.

Security and privacy
No screen recording, no ambient capture, no keystroke trail
No microphone and no meeting capture
Khint can't retrieve what it never saw: there's no rewind
Sessions and their entries stay local and never sync
Pixels are read once, on a region you drew yourself
That screenshot is discarded as soon as the text is out
Khint free, then from €7/mo · Rewind Mac $20/mo

What each one remembers

This isn't a feature gap. It's a different bet on what a memory should be allowed to see in the first place.

Rewind: what it captures

Rewind's bet is total recall: every window, every meeting, recorded and queryable afterwards. It's the feature Khint refuses to build, so there are questions Rewind answers that Khint never will.

  • Continuous recording of every window you see, plus every meeting you join if you opt in.
  • Stored locally and encrypted, queryable through Rewind AI. The pitch is total recall.
  • You never have to remember to remember, because the capture is on by default.

Twelve capabilities,
two memory models

Capture, storage, AI access, MCP, pricing. Including the rows where Rewind simply knows more than Khint ever will.

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 isn't stored after text is extracted. There's 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 doesn't record your screen or your audio.

Where is my data stored?

Locally first. Your Khint history, your packs and your Memory sessions all live in a SQLite file on your Mac. If you sign in, your history and your packs also sync to a Supabase Postgres database, encrypted at rest and reachable only through our service key; Memory sessions never sync at all. Nothing else leaves the device unless you run an agent, which sends the text you gave it to the model.

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 doesn't sell user data, and our inference providers' API terms prohibit training on customer inputs and outputs. We don't run any fine-tunes ourselves. Sub-processors are Anthropic and OpenAI (inference), Groq (voice dictation), Clerk (auth), Supabase (sync), Stripe (billing) and DigitalOcean (hosting). The privacy policy lists them all.

Memory that only sees what you choose

The active work session's summary is prepended to every AI action prompt. Free, and no always-on capture, ever.
