PromptGate for claude.ai

Scores your prompt on claude.ai (0-100) and offers three rewrites you can drop into the box. Runs locally. Nothing is sent out.

Every weak prompt costs you twice: a drifting answer and a second prompt to fix it. PromptGate sits next to the claude.ai composer and scores your prompt from 0 to 100 on 7 dimensions (goal, context, output, constraints, acceptance, economy, depth) as you type. Click the PG badge or press Ctrl+Shift+P to see: • Score, task type, depth, and what is still missing. • Three rewrites: A · Lean, B · Standard, C · Deep, with context filled from the chat. • Click one to place it in the composer. Nothing is sent. You always press send. Privacy: everything runs in your browser. No network calls, no accounts, no telemetry. The only permissions are storing settings and running on claude.ai. Vietnamese / English, following the prompt's language. Open source (MIT): github.com/huuthanhueh-debug/promptgate. Same engine as the PromptGate plugin for Claude Code.
