Rewrite anything,
right where you are
Select text in any Mac app and a floating toolbar appears — Polish, Format, Proofread, make it Funny, add Emoji, or Write from scratch. Powered by your own OpenAI or DeepSeek key. Nothing leaves your Mac except the request you choose to send.
An AI rewrite is one selection away
Works In Every App
Select text anywhere — Mail, Notes, Slack, your browser, even terminals like Warp — and a floating toolbar appears at your cursor. Reads the selection over the Accessibility API, with a clipboard fallback for apps that don't expose it.
Six AI Actions
Polish for clarity, Format for structure, Proofread for grammar only, Make it Funny for a witty rewrite, Add Emoji to liven it up, or Write Anything from a topic. Each is a tuned prompt — not a generic chatbot.
Streams, Then You Decide
The result streams in live so you see it forming, then you choose: Replace the selection, Insert below it, Copy, Regenerate, or Discard. Nothing is changed until you say so.
Bring Your Own Key
Point it at OpenAI, DeepSeek, or any OpenAI-compatible endpoint (Groq, Together, a local model). Your key, your model, your bill — pick the provider and model in Settings.
Your Key Stays Local
The API key lives in your macOS Keychain (or an environment variable). No FavTray account, no proxy, no middleman — requests go straight from your Mac to your provider.
Safe By Design
Long or empty selections are rejected before any request. Selected text is sandboxed against prompt injection, password fields are skipped, and your clipboard is snapshotted and restored around every action.
For everything you type all day
Polish a Slack message
Dash off a reply, select it, hit Polish — clearer wording in your own voice before you send, without leaving the thread.

Catch typos and grammar in Mail without copy-pasting into another tool. Proofread changes the minimum and keeps your voice.

Select a few rough notes, pick Write Post, add a line of direction — get a confident draft you can edit and ship.
Read more →Clean up pasted text
Format strips the broken line-breaks and spacing out of text copied from a PDF or webpage, without rewording it.

Which AI models can I use?
Any OpenAI-compatible chat endpoint. FavTray ships presets for OpenAI (gpt-4o-mini) and DeepSeek (deepseek-chat), plus a Custom option where you set the base URL and model — so Groq, Together, OpenRouter, or a local Ollama server all work. You bring the key.
Does my text or API key go to FavTray's servers?
Never. FavTray has no servers in this loop. Your API key is stored in the macOS Keychain (or read from an environment variable) and requests go directly from your Mac to the provider you chose. We never see your text or your key.
How do I trigger the toolbar?
Just select text with the mouse in any app — drag across it or double-click a word — and the toolbar appears at your cursor. Press Esc or click away to dismiss it. There's a minimum selection length so it never flashes on accidental clicks.
Will Replace work in apps like WhatsApp or a terminal?
Yes for editable fields — write-back uses the clipboard and ⌘V, then restores your original clipboard. In a terminal, scrollback isn't editable, so Replace pastes at the prompt; Copy and Insert still work everywhere.
Is AI Writer free?
It's a Pro-tier feature, included with the Personal plan (₹49/month) and the Lifetime license (₹2499), and fully available during the 30-day trial. You also need your own provider API key — usage is billed by your provider, not by FavTray.
Does it need any permissions?
It needs macOS Accessibility permission to read your selection and type the result back — the same permission the Window Manager uses. Grant it once in System Settings; everything stays on your Mac.
