Inject prompts into major AI web chat boxes through URL parameters, with optional auto-send.

Overview

Universal AI URL Prompt is a browser extension for reproducible AI workflows. You can share a single URL and let the target AI page open with a prefilled prompt, then auto-submit if needed.

Key Features

• URL-based prompt injection with ?prompt=, ?q=, and ?p=
• Auto-send enabled by default, with ?autosend=0 to disable
• Per-platform enable/disable switches in the extension Options page
• Send-button detection for English, Chinese, Japanese, and Spanish
• SPA-aware retry and scheduling for delayed input rendering
• Platform-isolated configs with a shared runtime for easier maintenance

Supported Platforms (20)

• ChatGPT, Gemini, Claude, DeepSeek, Microsoft Copilot
• Doubao, Perplexity, Kimi, Meta AI, Tencent Yuanbao

Project Structure

• platforms/_registry.js: platform registration and schema validation
• platforms/*.js: one platform definition per file
• content.js: shared runtime (URL parsing, injection, auto-send flow)
• scripts/platform-loader.js: shared platform-definition loader
• scripts/generate-manifest.js: generate manifest.json from platform files
• scripts/validate-platform-contract.js: validate platform definitions and E2E mappings

Privacy

This extension does not send data to developer-owned servers. It keeps a short-lived in-memory prompt cache (up to about 3 minutes) in the extension runtime for SPA navigation handoff. It stores platform on/off preferences in Chrome extension storage (chrome.storage.sync or local fallback) so your choices persist. When auto-send is enabled, prompt content is sent only to the destination AI website as part of normal page usage.
