Paid plans
Pro: $6.67/user/month billed monthly, or $80/year — unlimited cloud transcription, 20 hours of meeting recordings/month, device sync. Business: $13.33/user/month (or $160/year) adds unlimited meeting recordings and chat over your own data. Enterprise is custom and adds SSO/SAML and admin controls.

What OpenWhispr is good at

OpenWhispr is genuinely open source and MIT-licensed, same as Wren, and it covers a lot more ground. Underneath the dictation feature it also runs an AI agent you can talk to, meeting transcription with speaker diarization, a notes app with semantic search, and team spaces. Local transcription is free and needs no account: Whisper and Nvidia Parakeet models run on-device, with GPU acceleration on Metal, CUDA, or Vulkan. You can also bring your own API key for cloud processing, or sign in and pay for OpenWhispr's own hosted cloud tier, which starts at $6.67 a month. That's the main structural difference from Wren: OpenWhispr is building a broader productivity suite with an optional SaaS layer on top, while Wren stays a single-purpose dictation tool with no accounts or subscriptions anywhere in it.

How Wren is different

  • Wren runs on Tauri v2 with a disposable webview and a natively rendered recording overlay built on wgpu, so only a small Rust process stays resident once you're not dictating. OpenWhispr runs on Electron 41, which bundles its own Chromium and Node runtime, a heavier baseline for an app meant to sit in the background.
  • Wren has no accounts and no subscription of any kind. The local path is the entire product. OpenWhispr's local transcription is also free and doesn't need an account, but the app additionally sells a first-party cloud subscription (OpenWhispr Cloud, from $6.67 a user per month) for hosted transcription and meeting hours, plus sign-in-gated team spaces and sync.
  • Wren does one thing: press a shortcut, speak, and the text lands wherever your cursor is. OpenWhispr bundles that with an AI chat agent, automatic meeting transcription and speaker diarization, a notes app, and calendar integrations, a much bigger product if dictation is all you were after.
  • OpenWhispr ships on macOS (Apple Silicon and Intel), Windows, and Linux today, all from the same releases page. Wren's download page currently lists Linux and Windows only; an early Apple Silicon macOS build is up on GitHub Releases but hasn't made it to the main download page yet.
  • OpenWhispr's interface is localized into ten languages, including English, Spanish, French, German, Portuguese, Italian, Russian, Japanese, and two Chinese variants, through its own i18next setup. Wren's UI currently ships in English and Portuguese (pt-BR).

Questions, answered

Is OpenWhispr free?

Local transcription is free and doesn't require an account: Whisper and Nvidia Parakeet models run on your machine at no cost. OpenWhispr also has a free cloud tier once you sign in (2,000 words a week of cloud transcription, 5 hours of meeting recordings a month), and paid Pro and Business plans starting at $6.67 a user per month for unlimited cloud transcription and more meeting hours.

Is OpenWhispr open source?

Yes. It's MIT-licensed and the full source is on GitHub, the same license Wren uses. The repo covers more than dictation though: the AI agent, meeting transcription, and notes app all ship from the same codebase.

Does OpenWhispr work offline?

Yes. Local transcription runs on-device through whisper.cpp and sherpa-onnx, with GPU acceleration on Metal, CUDA, or Vulkan, and nothing leaves the machine in that mode. Cloud processing is opt-in, either through OpenWhispr's own hosted service or a key you bring yourself.

What's the real difference between Wren and OpenWhispr?

Mostly scope. Both are free, open source, and local-first by default, with an optional bring-your-own-key cloud path, so that part is a genuine similarity, not a differentiator. OpenWhispr builds outward from there into an AI agent, meeting transcription, notes, and a paid cloud subscription. Wren stays narrow: a global shortcut, local transcription by default, and pasted text, with no accounts or subscriptions anywhere in the app.

Does OpenWhispr run on macOS?

Yes, with native builds for Apple Silicon and Intel Macs alongside Windows and Linux, all listed on its GitHub Releases page. Wren's macOS support is earlier: an Apple Silicon build is published on GitHub Releases, but it hasn't reached the main download page next to the Linux and Windows builds yet.
