AI-powered knowledge that sticks
Ask anything. Save the best answers as Scrolls. Come back any time — your knowledge, always at hand.
The Problem
The problem with AI answers today
of people re-Google questions they've already found answers to before
before AI chat history becomes too long to search through effectively
knowledge saved from your last 100 AI conversations — unless you use ChatScroll
How It Works
Ask once. Keep forever.
Stop re-Googling the same thing. Every question you ask becomes a searchable knowledge note in your personal library.

What is the CAP theorem in distributed systems?
The CAP theorem states that a distributed system can only guarantee two of three properties:
- • Consistency — every read gets the latest write
- • Availability — every request gets a response
- • Partition tolerance — survives network splits

More than just a chat history
ChatScroll turns your AI conversations into a living knowledge system you can search, share, and study.
Semantic Search
Find scrolls by meaning, not just keywords. Type a concept and AI surfaces the most relevant results — even when the words don't match.
Share Scrolls
One click generates a public link anyone can open — no account needed. Share your best explanations with teammates, students, or the world.
Study Mode
Flip through your scroll library like flashcards. See the title, reveal the full answer, navigate with keyboard shortcuts — built to make knowledge stick.
Export to PDF & Markdown
Download any scroll as a beautifully formatted PDF or a portable Markdown file with YAML frontmatter — your notes, in any format you need.
