Real-time translation
Decodify watches the DOM for every file created, package installed, and command run — then translates each action into a subtitle you can read.
90% zero network
L0 template matching handles ~90% of actions locally in your browser. No server call, no latency, no cost. Only rare actions hit the AI.
BYOK
Bring Your Own Key. Add your Anthropic API key for unlimited Claude Haiku translations. Stored locally — we never see it.
English & Spanish
Every subtitle, every UI element — fully translated. Switch between English and Spanish with one click in the popup.
Privacy first
Only the action type and filename are processed — never your source code. The overlay runs in a Shadow DOM so it can't touch the host page.
Zero interference
Shadow DOM overlay with <50ms observer overhead. Draggable, minimizable panel that never breaks Bolt.new, Lovable, or Replit.

Building software by describing what you want to an AI agent instead of writing code. Tools like Bolt.new, Lovable, and Replit write the code for you — but you often don't know what they're doing. That's where Decodify comes in.
Right now: Bolt.new, Lovable, and Replit. We use an adapter pattern, so adding platforms is fast — v0, Cursor, and Webflow are next.
About 90% of agent actions are common patterns. Decodify handles these with local templates — zero network, zero latency, zero cost. Only unique actions need AI.
