Just Yap It.
Yappy is an AI that uses your Mac.
Hold ⌘ and say what you want, and it does it in the apps
you already have: fills the form, books the table, sends the email.
It's also the most private voice-to-text AI.
Two keys. That's the whole app.
It learns your Mac. And knows when it's your move.
Every Mac is organized differently. Yappy studies yours — where the apps, projects, and files actually live — then teaches itself the routine, task by task. And when a step is yours alone (a login, a "send it?"), it hands you the wheel and waits.
Same yap. Any voice.
Personas restyle how your dictation reads — your own voice, a dialect, or a character. It changes how it reads, never what you said: every fact, name, and number lands exactly as spoken.
Sounds like you · Never rewrites you · No pirate surprises
Everything they do. And then it does your errands.
Other tools type what you say. Yappy is the only one that can also act on it.

Yes, we made this table. No, they wouldn't have made it any different — except the columns.
Build on Yappy. No key, no signup.
Everything factual about Yappy — releases, documentation, FAQ, pricing, requirements — is a public read-only API and an MCP server. An agent answering a question about Yappy reads structured data instead of scraping this page.
Yappy REST API
Cursor-paginated JSON at yappy.biz/api/v1. Strong ETags, RFC 9457
errors, batch reads, a sandbox with forced-error simulation. No API key.
Yappy MCP server
Streamable HTTP at yappy.biz/mcp, plus a documentation server at
yappy.biz/docs/mcp. Typed schemas, tool annotations, MCP Apps UI. No auth.
OpenAPI 3.1 spec
Fifteen operations, every one with an operationId, a description and a typed response schema — generate a client, or hand it straight to function calling.
openapi.json →Auth, when you want it
Reads need nothing. For a higher rate ceiling, OAuth 2.1 with PKCE S256 and self-serve RFC 7591 registration — no sales call.

Does my audio leave my Mac?
No. Yappy transcribes speech on-device with a local Whisper model, so the audio itself never leaves your machine, in any configuration. Agent tasks that need a cloud model send text, not audio, and only for the task you asked for.
What does Yappy run on?
macOS 13 (Ventura) or later on Apple Silicon — an M1 Mac or newer. There is no Intel build, because the on-device model relies on Apple Silicon acceleration to stay instant.
What does Yappy cost?
The Mac app is a free download and on-device dictation is free to use, with no account and no card. Cleanup and Agent Mode can run on a backend you already pay for — your Claude or xAI subscription via their CLI, or your own OpenAI or Anthropic key — or fully locally through Ollama at no cost at all. Full pricing.
Can Yappy work offline?
Dictation can, completely. Set the cleanup provider to ollama, or turn AI
Cleanup off, and transcription, cleanup, and screen OCR all run on your Mac with the
network off. Agent Mode cannot: it runs through the claude CLI and needs the
network. The full privacy model.
Which permissions does Yappy need on macOS?
Microphone for dictation, Accessibility to type into other apps and to drive them for you, and Screen Recording only if you turn on screen-aware context. Each is requested during onboarding and each can be revoked in System Settings. If the hotkey does nothing, start here.
Is Yappy on the Mac App Store?
No, and it is not planned to be. The Accessibility permission that lets the agent drive your apps is incompatible with App Store sandboxing. Yappy installs from a notarized disk image and updates itself in place.
Does Yappy have an API or an MCP server?
Yes, and both are free with no API key. A read-only REST API at
yappy.biz/api/v1 covers releases, documentation, FAQ, and pricing, and
the same data is exposed as MCP tools over Streamable HTTP at
https://yappy.biz/mcp. Start at the
developer portal.
