Chatter
Practice a language by talking to an avatar. Speech stays on your device; a conversation costs nothing to serve.
In development, working title
Working title (a store name-collision check is pending). Backend and Flutter app are green in tests; payments are stubbed; mobile builds are not yet compiled in CI. Planned app ID: ch.zzd.chatter. Furthest from launch of the three.
Language apps die by server bills: cloud speech recognition and synthesis cost real money per minute, which forces aggressive paywalls. Chatter runs speech-to-text and text-to-speech on the device, so free users cost approximately nothing and the freemium math actually works. SQLite on one small node, a self-contained web build, on-device speech.
Where it stands
