Voicebox: Open Source Whisper Tool Using Cloudflare AI for Instant Transcription

Open Source, Free Tier Capable Whispr Using Cloudflare AI

I built Voicebox, an open-source desktop app that lets you speak and instantly get formatted text pasted into your current workflow. By combining a Wails client with Cloudflare Workers, the tool streams your audio to Whisper for transcription and an LLM for formatting, all while keeping costs low with a free-tier capable architecture.

Press a hotkey, speak, release — formatted text lands in your clipboard and is auto-pasted into whatever you were typing in.

    Is there a reason not to use built in macOS transcribing? Genuinely curious what the goal is here, though points given for coolness factor.

More from this day
