Oak reads between the lines
Read deeper, not just faster
Open any PDF and ask Oak what it means. Summarize a chapter, explain a concept, translate a passage — Oak reads alongside you so every page earns its time.

Your notes become a conversation
Highlight a passage and Oak surfaces what matters. Add notes, sketch ideas, mark key points — your annotations become a dialogue with the text, not just color on a page.

Find the answer without hunting it down
Ask once. Oak searches across your entire library — every PDF, every highlight, every note — and answers like someone who's read every page.

Built for how you actually read
Open any paper, any report, any manual — and just ask. Oak reads the full document and answers in context, whether you need a summary, an explanation, or a second opinion on what you just read.
AI Chat
Every PDF, article, and web snapshot in one place, organized your way. Collections, tags, and full-text search mean you always find what you need — even when you can't remember where you saved it.
Library
Highlight key passages, drop notes in the margin, sketch a diagram right on the page. Your markup is saved separately, so the original stays clean while your thinking lives on top.
Annotations
Talk to your documents instead of typing. Ask a question out loud, hear Oak's answer, and keep your eyes on the page. Perfect for long reading sessions when your hands are full.
Voice
Watch a lecture, a talk, or a tutorial — and ask Oak about it afterward. Oak follows along with the transcript so you can search, summarize, or revisit any moment without scrubbing through the whole video.
YouTube
Found an article worth keeping? Save it straight from your browser into Oak. Web snapshots preserve the content exactly as you found it — no broken links, no paywalls, always available.
Web Capture
Local & Private first
Oak keeps everything on your Mac. Your documents, notes, and conversations never leave your machine unless you choose otherwise. AI queries go directly to the provider you pick — Oak never sees them in between.
Your API keys stay local. Your reading history stays local. Your annotations stay local. That's not a feature — that's how it should work.
