What were the key decisions from last week's product meeting?
Based on your docs, here are the 3 key decisions:
Ship v2 onboarding flow by March 15
Pause the mobile redesign until Q3
Hire 2 more engineers for the API team
Who's leading the onboarding redesign?
How it works
Three steps to a smarter you
No complicated setup. No PhD required. Just upload, let AI do its thing, and start asking questions.
Feed your brain
Drop in PDFs, paste text, or add URLs. Research papers, meeting notes, docs — throw it all in. Your second brain eats everything.
AI does the heavy lifting
We chunk, embed, and index everything automatically. Your content becomes searchable by meaning, not just keywords. It takes seconds, not hours.
Chat on any website
Open the extension on any webpage. Ask questions, get instant answers pulled from YOUR documents. It's like having a genius assistant who's read everything you've ever saved.
What does our API rate limit look like?
Your API allows 1,000 req/min on the free tier and 10,000 req/min on Pro. Rate limits reset every 60s with a sliding window.
How do I increase it?
Features
Everything your brain needs
We handled the hard parts so you can focus on what matters — actually using your knowledge.
Any format, any source
PDFs, text files, web pages, Notion docs — toss it all in. We'll figure out the rest.
Semantic search
Find stuff by meaning, not keywords. Ask "revenue growth" and find the paragraph about "sales increase."
Chat that actually gets it
Natural conversation. Follow-up questions. Context awareness. Like talking to someone who's read all your docs.
Multiple knowledge bases
One for work, one for research, one for that side project. Keep your brains organized.
Always shows its sources
Every answer comes with receipts. Click through to the exact document and page.
API for builders
Want to build on top of it? Full REST API. Embed your knowledge base into your own apps.
Use cases
Built for people who read too much
(and forget where they read it)
Teams
"Wait, who decided that?"
Upload meeting notes, strategy docs, and wikis. Never dig through 47 Google Docs again — just ask.
Researchers & Students
"I read this somewhere..."
Drop in papers, textbooks, and lecture notes. Your AI study buddy remembers everything you don't.
Support Teams
"Let me check our docs"
Feed it your help docs, SOPs, and runbooks. Answer customer questions in seconds, not minutes.
Knowledge Workers
"I have 200 bookmarks..."
Turn your bookmark graveyard into a living, searchable brain. Every article and save, instantly accessible.
Your knowledge, always one click away
Stop searching. Start knowing. Install the extension and give your browser a brain.
