Smart writing, real-time writing assistant, on-device AI models, notes, stickers, and a clipboard that follows you across apps. Bring your own API key, run models offline, or use ours — pick the plan that fits. Start free for 3 days.
No more copy-pasting between apps. Keyda puts your AI, notes, snippets and clipboard one tap away — right where you type.
Select any text to fix grammar, rephrase, translate, summarize, make it shorter or longer — or tap the AI button to ask anything. Powered by your favourite AI provider or on-device model.
Run best-in-class open-source language models completely offline on your phone. No network, no cloud cost, no privacy worry. Available on Lite and Pro.
Save notes from the keyboard, read them from anywhere. Stored securely in your account, scoped per-user — never shared.
The last 50 things you copied, one tap away from any app. Smart paste detects URLs, code and addresses automatically.
Generate stickers from a text prompt with an on-device image model. Pure offline — nothing leaves your phone.
Detects foreign-language clipboard and offers a one-tap translation chip. Reply in the language you actually speak.
Copy a message someone sent you, tap the response button, and Keyda drafts a reply from your perspective — not as an AI. No more "I'm a language model" awkwardness.
Opt in and Keyda remembers context per text field — chat threads stay coherent across multiple AI calls. All on-device, auto-pruned after 30 days, one tap to forget everything.
Add a short bio about yourself in Settings and the AI uses it to personalise replies — tone, language, register. Your bio stays on your device; only sent to the AI when you make a call.
Type 12*15 = or next thu 3pm and Keyda fills the result instantly. Like a calculator and a calendar, built in.
Classic, Midnight, Aurora, Coral, Forest, Ocean, Sunset, Rose, Carbon. Switch any time — your keyboard, your look.
GPU layer caching and prepared haptics make every keystroke instant — even while AI runs in the background.
Six real-time writing tools that run entirely on-device — no API call, no latency. Available on every plan, free trial included.
Select any typed text and pick a tone — Formal, Casual, Friendly, Professional, Direct, or Empathetic. Keyda rewrites it in seconds. No copy-paste to a chatbot required.
As you finish each word, Keyda checks a built-in dictionary and shows a one-tap swap chip for non-inclusive terms. Runs 100% on-device — no AI call, no latency.
A live badge in the suggestion bar shows whether your draft reads as Formal or Casual, updated after every sentence — without any network call or model inference.
Writing a research paper? Keyda detects mixed APA, MLA, and IEEE citation styles and flags it the moment you close a citation — before your editor catches it.
A heuristic badge scans your draft for phrases over-represented in AI-generated text. If the score is high it shows "🤖 Likely AI" — a prompt to review before you send.
Type a relative date like "next Friday at 3pm" or "in two weeks" and Keyda offers the fully formatted date as a one-tap chip — no switching to a calendar app.
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. 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.
