Claude Chat HUD — Keyboard Overlay for AI Chats

Try the interactive demo (no install needed): https://asdprompt.com

Hint labels appear next to every text block. Type a letter to select it. Keep typing to drill down: block → sentence → word. Then copy the AI response, or fire a follow-up prompt — all without touching the mouse.

Four keystrokes. Hands never leave the keyboard.

HOW IT WORKS
1. ⌘/Ctrl+Shift+S — activate the overlay
2. Type a hint letter — select a text block
3. Drill down (optional) — narrow to sentence, then word
4. Act — Enter to copy, or your current action fires automatically
