Annotation Intelligence

It reads the document. But it also reads you.

Most AI tools only see the text. Outpour's AI sees what you highlighted, the notes you wrote, and the connections you drew.
It knows the difference between text that exists and text you cared about.
Ask it anything. It answers from your perspective, not just the author's.

Your understanding

"What gaps do I have in my understanding of this paper?"

"Explain attention mechanisms" → sees your note "how is this different from convolution?" and tailors the answer to your specific confusion

Across your library

"What have I highlighted about gradient descent across all my papers?"

"What are the key concepts I've marked across all my reading?"

Metacognition

"Am I struggling more with the math or the theory?"

"What should I read next based on what I've been focusing on?"

Deep Research

Your annotations become connected intelligence.

Indexed for precision. Embedded for meaning. Mapped into a knowledge graph of connected ideas. That layered intelligence powers multi-step reasoning across your entire library — not just the PDF you have open.

Watch the agent search, read, and think in real time. Every answer cites the exact page.

Three layers of understanding: index, vector embeddings, and knowledge graph

Think alongside what you read

Notes, images, math, code. Drop anything onto an infinite canvas beside your PDF. Connect ideas with arrows, group related thoughts. Your reading and thinking, in one flow.

Notes that feel like Notion

Each canvas card is a full block editor. Type / for headings, lists, quotes, code, and math. Drag to reorder. If you've used Notion, you already know this.

Smart Dark Mode

Dark mode that doesn't destroy your images

Most PDF tools either skip dark mode entirely or invert everything, turning photos into negatives and making diagrams unreadable.

Outpour does it differently. Text and backgrounds adapt for comfortable night reading while your photos, diagrams, and figures stay in their true colors.

Inverted

Smart

Ask directly in your canvas

Type /ask anywhere on the canvas.
AI sees your highlights, notes, and the PDF you're reading, and answers right where your thinking lives.

See where your time goes

Track reading sessions, set weekly goals, and see which documents take the most time. All stored locally.

See only what matters

Strip away everything except your annotations. Review hours of reading in minutes.

All your PDFs, organized

Organize books by topic, browse covers, and see your engagement at a glance.

Your ideas, mapped in 3D

Every concept from your highlights and notes is extracted and mapped into an interactive 3D graph. See how ideas connect across your entire library.

Tuned for long reading sessions

Six themes — Light, Classic Light, Sepia, Dark, Classic Dark, and Auto. Each one is carefully tuned with reduced contrast ratios in both the PDF and UI, so hours of reading don't strain your eyes.
