KURAI

Test build. Fixes the line you're typing, in any app, when you tap FIX. English, Estonian, Russian.
Download Kurai
  1. Open the downloaded file and install it. Android will ask to allow installs from this app (Chrome / Files): allow. Google Play Protect may ask to scan it first: Scan app, then Install.
  2. Open Kurai, type your name, tap Open accessibility settings, find Kurai (Samsung: Installed apps). It is greyed out, "Controlled by restricted setting": tap it anyway and press OK on the box.
  3. Now Settings → Apps → Kurai, three dots top right, Allow restricted settings. No three dots? They only exist after the tap on the greyed row in step 2 (and hide again if you pressed Cancel there): go back, tap the row, press OK, come back. Then back in Accessibility, switch Kurai on.
  4. Back in Kurai it asks to stay awake: Allow, then OK. Without this your battery saver will switch it off.
  5. Go to any chat, type something messy, tap FIX. Tap a yellow word for other options. Hold a word that was fixed wrong and tap BUG to tell Jake.
Your line is sent to Jake's server and to Claude to be corrected, then thrown away. Nothing is stored except the bug reports you choose to send. 300 fixes a day for the test. New builds arrive as a notification: tap it, Update. More features inside the app explains everything.
