Ownmind: Offline AI Notes+Chat

Every app now needs a sign-in, collects your data, and ignores your privacy. When I set out to build Ownmind as a solo indie developer, privacy was my first thought: how do I deliver a feature-rich app that uses the minimum permissions and gives you full access to your own data? No cloud, no accounts, private by design.

Powered by Gemma 4, Google's popular open-weight AI model, running entirely offline on your device. Ownmind is built around a simple idea: externalize your thoughts. Get what's in your head onto the page, then talk it through with an AI that responds right on your device. It's less like chatting with a service, more like an extension of your own thinking. That's why it's called Ownmind. Nothing you write ever leaves your device unless you choose to export it yourself.

journal / checklist / chat in one simple canvas
No guided prompts, no rigid structure. Journal your thoughts, ask a question mid-entry, have a full conversation. It's a blank page that works however you think.

Show it a photo
Attach a picture and the AI can actually see it: describe it, answer questions about it, talk it through with you. Like everything else, the image never leaves your device.

Checklists, not todo lists
Check things off to feel good about what you did, not guilty about what's left. A small distinction that changes how the whole thing feels.

Your memories, in plain files you own
Everything you write is saved as a memory, a plain markdown file stored on your device. Export anytime, no lock-in, no proprietary format. Yours to keep, move, or back up however you like.

Open it on your computer
Ownmind can serve your memories to a desktop browser over your own local network, even hotspotting between your own devices, secured with a PIN. Type on a real keyboard without your data ever touching the internet.

Better for the planet, too
Cloud AI burns data-center energy for every message. Running the model on hardware you already own is private and a little greener.

Core features free forever
No catch, no paywall, no account. Journal, checklist, chat, on-device AI, browser access, and markdown export, all free, forever. The core AI gets updated as new models ship.

Ownmind Pro / Lifetime, for the curious

- Unlimited custom AI personalities (modify the AI system prompt)
- Biometric + seed phrase encryption for your memories

Pro is optional: a monthly subscription or a one-time Lifetime purchase. Pay once for Lifetime and it never expires. Purchases are tied to the Google account used at checkout; since Ownmind has no logins and collects no data, a purchase can't transfer to a different Google account.

Buying Pro directly supports independent app development.

Private by design. Offline by default.
