Mispher

About Mispher

Mispher is a dictation and agentic transcription application for macOS that runs entirely on-device. It transcribes speech, rewrites selected text in place, translates spoken language, and includes an agent that plans and executes tasks using local tools and MCP servers. No cloud processing, accounts, or telemetry are involved.

Review

Mispher combines local speech-to-text with an on-device agent that goes beyond transcription. Instead of sending audio to remote servers, all models run on Apple Silicon, with the user choosing from multiple recognizers per language. The agent can call Apple Notes, read the clipboard, access files, and connect to external MCP servers, with per-tool approval gates.

Key Features

• On-device transcription using Parakeet EOU, Parakeet TDT, CTC, Nemotron, or Qwen3-ASR, each selectable by language.
• Rewrite-in-place: highlight text in any app, hold a key, speak a command, and the selection gets replaced.
• Translation mode that converts spoken input in one language to written output in another.
• Ask mode powered by a local LFM2.5 agent that plans, calls tools (Apple Notes, clipboard, files, MCP servers), and shows a plan before executing writes.
• Customizable radial dial, hotkeys, HUD styles, tool approval policies, and model assignments per mode.

Pricing and Value

Mispher is free and released under the MIT license. There are no paid plans, subscriptions, or in-app purchases. The source code is available on GitHub.

Pros

• All processing stays on the Mac; no audio leaves the device and no account is required.
• Per-tool permission settings let you approve, ask, or deny each action the agent can take, including individual Notes operations.
• Multiple speech recognition backends are available, and you can assign different models to different languages.
• The radial dial and hotkeys are fully remappable, and three HUD styles are included.
• MCP server support with OAuth allows the agent to connect to external tools over HTTP or stdio.

Cons

• Requires macOS 26 and Apple Silicon; Intel Macs and other operating systems are not supported.
• On-device models may not match the accuracy of large cloud-based services for proper nouns and numbers unless a custom dictionary is configured.
• Not well suited for users who want a fully automated agent with no interaction-the agent prompts for approval on sensitive tool calls and there is no global pause for all approvals.

Mispher fits users who prioritize local execution, privacy, and the ability to extend the agent with their own tools. It's a practical option for dictation and light task automation on macOS 26, though those needing the highest out-of-the-box transcription accuracy for specialized terms might need to invest time in custom dictionaries. The rewrite-in-place and translation features work across many apps, and the open-source license allows for inspection and modification.
