CORE VALUE
Everything you read, in one place.
Books, articles, posts, notes — all the scattered things you've read, unified into a single Penciive library.
Five content types,
one screen.
EPUB, PDF, web articles, X posts, and your own notes. Regardless of format, search and filter everything from a single tab.
- →Auto-organized by category and tag. Knowledge work, tooling, productivity — sorted by your own context.
- →Save the moment you read it via the Chrome extension or iOS share sheet.
- →Cards with thumbnail, author, and date — easy to remember later.
Don't save for later —
highlight now.
Long-press to highlight any passage. Color, notes, and tags — all in one motion, with one hand. Turn passive reading into a real knowledge asset.
- →Four-color markers to color-code.
- →A note field lets you jot down your interpretation in the moment.
- →Tag highlights to search across themes later.
Ask AI about
your own library.
Just ask what you're looking for. Penciive reads what you've saved and answers with citations. A knowledge base that's truly yours.
- →Source links with every answer — the citation is traceable.
- →Filter by category (web only, social only, notes only).
- →Keep history — resume the same question later.

Three actions, that's it.
Keep only the information you need.
AI-generated notes — all "someone else's thinking".

03 — ASK
Ask your own library.
Don't re-read your archive — ask AI. RAG always shows sources, so search and thinking happen together.
HOW IT WORKS
Three steps to a second brain.
1
Just save
See something on the web or an X post? Save it via URL or share. EPUB / PDF? Drop them in.
2
Highlight as you read
Highlight what matters in four colors. Add a note and a tag.
3
Ask AI
"Summarize my web articles about Obsidian" — query your entire library or by category.
WHY PENCIIVE
Read-it-later isn't enough anymore.
Saving is easy. But almost no app is designed for what happens after you save — how you actually use what you've kept.
