Voice Dictation
4 products ranked by how much of their useful core an AI coding agent can realistically reproduce.
Superwhisper
A push-to-talk recorder that transcribes and pastes text into the active app is very buildable for one person, especially on macOS.
MacWhisper
MacWhisper's solo core is compact: build a private local transcription pipeline that accepts an audio file, transcribes it, creates structured notes, and exports Markdown. A competent builder can reach a useful personal version, while the paid product mainly wins on capture, integrations, reliability.
Wispr Flow
Hotkey → record → Whisper → paste at cursor. One of the most-cloned apps of the trend for a reason.
Superscribe
The desktop dictation half is a solved one-sitting build with complete open-source clones to fork. The hero product is not that: live-transcribing calls on your existing iPhone number takes carrier call forwarding, a pooled Twilio number, a CallKit/PushKit softphone, and a dual-track media-stream pipeline that can only be debugged against live phone calls. And a clone gets you a transcript file, not the workspace around it: roughly 45k lines of API and web app that embed every recording, time block, and project (with synced GitHub repo context), auto-file notes and billable time to the right client, and expose it all as reports, semantic search, a public API, and an MCP server. Each piece is a documented recipe; shipping all of them integrated is the substantially larger part even before telephony.
