Voice typing, instant AI grammar correction, and a writing assistant that goes further — shared notes, group AI chats, photo and file attachments, and answers that remember what matters. On-device, your own API key, or ours. Free for 3 days.
No more copy-pasting between apps. Your AI, notes, files and clipboard live one tap away — and now you can share them and work on the same AI chat with the people who matter.
Select any text to fix grammar, rephrase, translate, summarize, or change its length — or tap the AI button and ask anything. Copy a message someone sent you and Keyda drafts a reply in your voice, from your perspective — never "as an AI". Works with our AI pool, your own API key, or an on-device model.
Tap the mic and talk — your words are typed for you, with smart self-correction so "29 oh sorry 30" becomes "30". The Voice Assistant goes further: change keyboard settings, pull up a saved note, set a reminder, or ask the AI to write something — all by voice, in any language.
Send a note or document to another Keyda user with one link — they get their own copy, credited to you. Or go further: invite up to 100 people into one shared AI chat, where everyone sees the same conversation and the same AI answers, delivered instantly. Plan a trip, run a study group, or brainstorm with your team — together, in one place.
Paste a web link and Keyda reads the actual page before answering. Attach photos, audio recordings, or documents (PDF, Word, text) to your question — the AI sees your images, transcribes your audio, and answers from your files' real content. Summarize a contract, describe a photo, or turn a voice memo into action items.
Save notes and documents from the keyboard and read them on every device. Keyda's AI remembers what you've saved — and what you've discussed — and quietly brings it into future answers when relevant. Search everything by meaning, not just exact words: "trip planning" finds your "Goa itinerary" note.
Six tools that run entirely on-device with zero latency: a tone adjuster (Formal, Professional, Empathetic and more), inclusive language suggestions, a live formal/casual tone indicator, citation-style consistency checks, an AI-text detection badge, and smart date chips that turn "next Friday 3pm" into a formatted date.
Run best-in-class open-source language models completely offline on your phone. No network, no cloud cost, no privacy worry — your text never leaves the device. Available on Lite and Pro.
Type what you need and tap the chip: "sweet shops near me" returns a ready-to-send list with map links, "remind me to call mom at 5pm" sets a reminder, "meeting tomorrow 3pm" creates a calendar event. Your last 50 copied items stay one tap away, and smart paste recognises links, codes and addresses automatically.
Generate stickers from a text prompt with an on-device image model — pure offline, shareable to WhatsApp, synced across your devices. And make the keyboard yours with 9 hand-tuned themes, from Classic to Midnight to Aurora.
Every time you switch to a chatbot to fix a sentence, you lose context, break your flow, and waste 30 seconds. Keyda puts AI exactly where your fingers already are.

Your data is scoped per user — sign-out wipes every note, clipboard, sticker, BYOK key, profile photo, bio and AI memory for the outgoing account before the next one signs in. BYOK API keys are stored encrypted (AES-256-GCM) and only used to call your provider. AI Memory and your bio live in a private on-device SQLite file — they never leave your phone unless you fire an AI call that needs them. Voice typing only uses the microphone while you're actively recording — audio is transcribed by Apple's on-device/Apple-hosted Speech Recognition, never stored by us, and your voice transcripts stay on your device unless you opt in to cloud sync. On-device models run entirely offline. We don't sell your data and we don't read what you type. Full details on the Privacy Policy page.
