Mnema recording and timeline interface on macOS

// how it works

It records. You recall. The AI reasons.

  1. ● rec

    record

    Mnema runs in the background, capturing your screen, what you hear and say, and which apps you use. It pauses itself when you step away, and you can pause it or hide any app any time.

  2. ⌕ query

    recall

    Summon a search bar from anywhere and find any moment in seconds: by what was on screen, what was said, or which app you were in. Scrub your whole day back to the exact frame.

  3. ∴ answer

    reason

    Ask plain-language questions about your past, answered from your own history. Over time, Mnema builds a private picture of how you actually spend your time.

// recall

Find the one moment in a year of them.

Search by what you saw or heard, filter by app or time, then scrub a live timeline of your day to the exact frame: full-res screen, audio, and transcript.

// what it captures

Screen, audio, and activity. All searchable.

Three streams of your day, captured continuously and turned into one searchable record.

screen

text

Every window, tab, and document you look at becomes searchable text. Find that paragraph by its exact words, or by what it meant when you can't remember the wording.

audio

transcript

Meetings, calls, and voice notes are transcribed with speaker labels, so you can search what was said as easily as what was written.

activity

timeline

Which app, which site, how long: a quiet log of your workday you can filter, scrub, and ask questions about. It even remembers the page, so you can jump back to the exact tab.

// ask ai

Ask your own memory a question.

Type a question the way you'd ask a colleague who never forgets. Mnema answers from your own history, and every answer links straight to the frames and clips it's drawn from, so you can verify it yourself.

  • cites its sources Jump from any answer straight to the exact frame or audio clip. No black box: you can always check the receipt.
  • keeps the thread Follow up, refine, and revisit past conversations in a searchable chat workspace that remembers where you left off.
  • your model, your choice Bring your own Anthropic or OpenAI key, or run a fully local model with no account and no key at all.

// insights

An AI that actually understands your work.

From everything it records, Mnema builds a quiet, private picture of how you spend your time: the projects you're deep in, where your focus goes, and what you keep coming back to. It's yours to read, correct, or wipe.

  • You've been heads-down on the Q3 dashboard launch for two weeks straight.

  • Your deepest focus is in the morning. Afternoons skew toward meetings and Slack.

  • always-on usage See time per app and site, when you're busiest, and how you hop between tools, without lifting a finger.
  • in your own words Tell Mnema about yourself and what you're working on, and its picture of you sharpens.
  • yours to correct Pin what's right, dismiss what's noise, and correct how it reads your day, or wipe its whole understanding without touching a single recording.

// private by construction

It all stays on your machine.

Privacy isn't a setting you switch on. It's how Mnema is built. Recording, reading text from your screen, transcribing audio, and search all happen on your Mac, and you hold every control.

Nothing leaves. Not to us, not to anyone.

  1. Stays on your Mac

    Capture, text extraction, transcription, and search all run on-device. No account, no servers, no telemetry. There's no Mnema cloud to send anything to.

  2. Secrets auto-redacted

    Passwords, keys, and tokens are detected and stripped from your record's searchable text, so neither an AI model nor a connected tool ever sees them.

  3. Encrypted at rest

    Your record is encrypted on disk, so it's protected even if your machine isn't.

  4. You choose what's kept

    Keep history forever or auto-delete after 7, 14, or 30 days. It's your call, changeable any time.

  5. Delete in one click

    Wipe the last few minutes of capture instantly, or clear the AI's entire understanding of you, without losing your recordings.

  6. Hide anything sensitive

    Exclude any app from recording, or pause capture entirely whenever you want privacy.

// and quietly, more

The small things add up.

  1. journal

    Play any day back like a receipt: what you did, hour by hour, with real thumbnails from your own screen.

  2. who said what

    Meetings get speaker labels, worked out on your Mac, and you can match voices to people you name.

  3. search by meaning

    Find things by what they were about, not just the exact words. Download one small model and it works on-device.

  4. back to the page

    Mnema can remember which page you were on and reopen the exact tab in your browser.

  5. your own tools

    Plug your own tools into Ask AI through MCP, so answers can draw on more than your history.

  6. cloud transcription · opt-in

    Want higher-accuracy transcripts? Use your own Deepgram account. Audio leaves your Mac only if you turn this on.

  7. low-disk safety

    Running out of space? Recording pauses itself and picks back up when there's room again.

  8. auto-updates

    Mnema keeps itself current in the background.
