OpenLess is a cross-platform (macOS & Windows) voice-input app — a fully open-source alternative to commercial tools like Typeless, Wispr Flow, Lazy, and Superwhisper.
Put your cursor in any text field — ChatGPT, Claude, Cursor, Notion, an email draft, a chat box — press one global hotkey and talk. OpenLess records, transcribes, polishes the text in the mode you picked, and inserts the result at the cursor. If insertion is blocked it copies to the clipboard, so the words you spoke don't get lost.
Unlike voice typing tools that just dump a word-for-word transcript, OpenLess's headline mode is AI-prompt mode: you ramble, it adds structure, lists constraints, and produces a context-rich prompt you can paste straight into ChatGPT / Claude / Cursor.
