A journal with an AI that never leaves your PC.

Write or talk, then ask your past anything. The AI runs on your own computer, so your entries are never sent to a server.

Ask your journal anything.

It has read every entry you've written. Ask in plain words and get a plain answer, with the entries it came from. It works the same with Wi-Fi off.

No online account

You sign in on your own PC. There's no MindSage cloud to sign in to.

No tracking

No analytics, no usage data, no ads. We don't know how often you write, and we don't want to.

Works offline

Writing, voice typing, search and Ask all keep working with Wi-Fi off.

MindSage isn't using it.

A year later, it brings the day back.

Add a photo to any entry. On the same date next year, MindSage shows it to you again, with what you wrote that morning.

Saturday, 12 OctoberLeft at 4:30. Kavya slept the whole drive, then talked the whole way up. Didn't check my phone for three hours.

Too tired to type? Talk.

Press the mic and ramble. Speech becomes text on your PC, so your voice isn't uploaded either.

Find it without the exact words.

Search by what you meant. "That weekend in the hills" finds the right entry even if you never wrote those words.

Free to write. Pro if you want more.
