Synapse Keyboard Features — AI Writing, Grammar, Translation

Other keyboards only fix grammar. Synapse gives you a full AI assistant — ask it to write emails, translate conversations, generate proposals, or fix grammar. Whatever you need, right where you type.

Fix grammar, spelling, and sentence structure in any app — one tap. No need to copy-paste to a separate editor.

Save custom prompts for messages you send often. Write client pitches, response templates, or greeting sequences once, assign a short keyword, and let Synapse expand it instantly in any app. Saving you hours of repetitive typing every single week.

Turn short triggers into full text instantly. Set up a shortcut like "omw" → "On my way!" or "addr" → your full address, and Synapse expands it the moment you hit space — in any app. It runs entirely on your device, works offline, and never spends AI credits, so your most-typed phrases are always one word away.

Your typing stays private. Synapse processes AI requests on-demand and does not log, store, or share your typing history. What you type in WhatsApp, Gmail, or notes is processed safely and securely.

Personalize your look and feel. Choose from 10 premium themes (like Cyberpunk Neon, Dark Elegance, and Glassmorphic Frost) and 9 custom key sounds (including Typewriter, Crystal Ping, and Neon Zap) to make typing a tactile delight.
