use.fo turns voice into polished text anywhere you type. Hold Fn on Mac or Right Alt on Windows, speak naturally, and release to paste clean writing into Gmail, Slack, Notion, docs, code comments, or any desktop app. It removes filler, fixes structure and punctuation, supports rewrite modes like email, work chat, translation, social posts, and image/video prompts, and keeps your flow inside the app you were already using.

Static templates? Boring. Use.fo adapts to YOUR context with dual-mode AI: 🆕 Deep Mode – Extracts your real intent (not just keywords), asks smart questions, then outputs structured prompts with success criteria. Like autocomplete for complex thoughts. 💬 Fast Mode – Instant mid-conversation polish that keeps your natural voice intact. The magic: PhD-level prompt engineering (intent analysis, reasoning, constraint mapping) → one ✨ click. Expert results, zero mental overhead.
