Worker calls Groq
The Worker calls Groq Llama-3.3-70B with a tightly scoped prompt — your key stays encrypted.

Structured bullets, Q&A, and quizzes — safe from prompt-leak tricks.

FAQ
Questions,
answered.
Everything you need to know. The Worker code is fully open — self-host everything.
What does summeriser. actually do?+
It's a Chrome extension that extracts text from the page you're on and sends it to your private Cloudflare Worker, which calls Groq to generate bullet-point summaries, answers and quizzes.
Where does the AI key live?+
Your Groq API key is stored as an encrypted Cloudflare Worker secret. It never ships with the extension bundle and is never visible to end users.
What can it summarize?+
Articles, PDFs, Google Docs (shared as "Anyone with the link"), YouTube videos, Reddit threads, Substack posts, and most regular webpages.
Does it work on paywalled content?+
summeriser. extracts whatever is rendered in your browser tab. If you have access and can read it, so can summeriser.
Is there a roadmap?+
Yes — Firefox support, Notion/Obsidian export, and team usage are on the list. You can adapt the Worker to your own stack today.

who actually read.
