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.

Sunrise over misty hills
Nandi Hills, 6:12am

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.

Will it run on your PC?

The AI runs on your computer, not ours, so it needs a reasonably recent PC.

Windows
Windows 10 or 1164-bit
Memory

MindSage checks your PC before the download and picks the AI that fits it: 8 GB PCs get a lighter model. If your PC can't run it well, MindSage tells you, instead of quietly sending your writing to a server.

Questions

Does MindSage work without internet?

Yes, once the AI has downloaded. Writing, voice typing, search and Ask all run on your PC. You need a connection for the first download, for updates you choose to install, and to buy Pro.

Which AI does it use?

Open models that run on your PC through llama.cpp: Llama 3.2 3B writes the answers (Qwen 2.5 1.5B on 8 GB PCs), nomic-embed-text powers search by meaning, and Whisper turns your voice into text.

Every model file is checked against its fingerprint after download, and a file that fails is never used.

Does it send my journal to ChatGPT or another AI service?

No. The AI runs on your PC. Your entries are never sent to us, to OpenAI, or to any other AI service, and they are never used to train anyone's models.

Can you read my entries?

No. There is no MindSage server that receives your writing, so there is nothing for us to read. The app has no analytics and sends no usage data.

Is my journal encrypted?

Not yet. Today your journal is stored on your PC behind your MindSage sign-in. We're adding encryption of the journal itself during the beta, and we won't call it encrypted until it is. Until then, turning on Windows device encryption or BitLocker protects it if your laptop is lost.

Why is the download so big?

That's the AI itself. Having the models on your PC is what lets MindSage answer without a server.

Is MindSage a therapy app?

No. MindSage is a journal with an AI that answers questions about what you wrote. It doesn't diagnose or treat anything and isn't a replacement for professional care. If you're in crisis, call your local emergency number or find a free helpline at findahelpline.com.

Is it on Mac or iPhone?

Windows comes first. Mac and iPhone are planned for later, with no date yet. Join the beta and we'll tell you when they're ready.

Write like nobody's reading.

(nobody is)

Join the beta for Windows 10 and 11. We'll email you when it opens, and rarely after that.

Windows only for now. For adults 18 and over.

We keep only your email, only to tell you about the beta. No tracking, never sold or shared. Remove it any time.
