Synto

Turn any page into Markdown, apply a prompt template, and send to OpenAI, Gemini, or Grok. Keys stay on your device.

Synto clips any web page to Markdown and sends it to ChatGPT, Gemini, or Grok from a Chrome side panel. No copy-pasting, no tab switching. What it does - Pulls the main content from any page (support tickets, Jira or GitHub Pull Requests, Reddit threads, Amazon listings, news articles) and converts it to Markdown. - 11 built-in prompt templates grouped by intent: Understand, Decide, Act, Compose. Edit them, pin favourites, or add your own. - Sends to OpenAI, Gemini, or Grok and streams the response back. Follow-up questions work. Pick which model to use per provider. - Select text before opening Synto and only that selection gets sent. - Conversations are saved per URL. Return to a page and pick up where you left off. - Two output modes: "Ask ChatGPT" streams the response in the panel. "Copy Markdown" puts the filled prompt on your clipboard, content and all, ready to paste into Claude, the ChatGPT web UI, or anything else. - Export any conversation as a .md file. - Bring your own API key. You pay the provider directly — no markups, no subscriptions. Privacy No backend, no accounts, no analytics. Open source. API keys stay in your browser. This extension never touches them. Page content goes straight from your browser to whichever AI provider you pick.
