Mentria is a small creative studio that builds software the do-it-yourself way: made by hand, shipped when it's ready, and answering to nobody but the people who use it. The site you're reading is a progressive web app. Everything inside it, from the tools and games to the AI, runs on the device in front of you. There is no backend pinging your prompts to a server farm. There are no trackers measuring how long you stared at the homepage.
We make tools that respect you: notes, timers, a QR scanner, an authenticator, an invoice maker, a shelf of games, AI chat that runs entirely in your browser, an infinite radio, and a daily feed of visual explainers. No accounts, no email capture, no cookie banner. If something here is useful to you, it stays useful when your wifi cuts out, and it stays useful five years from now, when whichever startup you signed up to has pivoted, lapsed, or vanished.
Everything you create here lives on your device. Back it up so a browser wipe doesn't take it with it.
PERSISTENT STORAGE GRANTED…
USAGE…
Encrypted backup
Choose a passphrase, download an encrypted file. Lose the passphrase and the backup is unrecoverable.
Restore
Pick a backup file and enter the passphrase you used.
Sync devices
Pair two devices with a one-time code. Data syncs peer-to-peer, end-to-end encrypted. Our relay never sees your data.
Mentria identity
—
An encrypted secret on this device that lets your other devices auto-link. Set it up once, restore from your backup elsewhere, and the rest is automatic.
Pair a new device
Show this code on the other device. The code is the encryption key — don't share it elsewhere.
