Your timeline is cached locally so you can browse without connectivity. Likes, boosts, and new posts queue up and sync seamlessly when you reconnect. No other Mastodon client handles offline as well as Coho.
Fast, private, and no server required — these features run entirely on your device:
- Instant translations — Translate posts without server round-trips
- Auto-generated alt text — Images missing alt text get descriptions automatically
- Alt text assistance — Generate alt text for your images before posting
- Voice input — Compose posts by speaking
- Handwriting input — Write posts with your handwriting, converted to text
Stay in Coho when you tap @mentions or #hashtags — we route to the right profile or tag without bouncing you to a remote server.
Install Coho on any device — iOS, Android, Windows, macOS, or Linux. It's a PWA with full offline support.
Choose your accent color and switch between light and dark mode.
Hide likes, boost counts, and other metrics for a calmer experience.
