Doclin

Open-source Mac dictation that also reads your coding agents aloud

Push-to-talk dictation anywhere

Hold Right Command, speak naturally, and release to insert text into the field you were already using — editors, browsers, terminals and chat boxes alike.

Local by default

The standard path uses Apple's on-device speech recognition and Kokoro/macOS voices, so your recordings and transcripts are not uploaded. Audio in local mode is never written to disk.

Spoken coding-agent updates

Hear progress from Codex (desktop and CLI) and Claude Code read aloud, so you can stay aware of a running task without watching the terminal.

Optional bring-your-own-key cloud features

OpenAI transcription, transcript cleanup, notification summaries and higher-quality notification voices are individually switchable and use your own API key.

Strengths & Pros

+Completely free and open source, with public source you can audit
+Local-first design: no recording upload in the default mode
+Unusual dual purpose — dictation plus spoken AI agent updates for developers
+Cloud features are opt-in and use your own key rather than a Doclin account

Frequently Asked Questions: Doclin vs HeyGen

+Broad localization support covering 175+ languages and dialects with editable scripts
+Strong enterprise readiness including SSO, SCIM, brand controls and LMS integrations
+Free tier and annual discounts let teams test the workflow before committing

Limitations

–Avatar realism can still fall into the uncanny valley for some viewers and use cases
–Serious production volume requires a paid plan, and enterprise pricing is quote-only
