Features

A toolkit shaped for the long arc of learning.

Six surfaces. One workspace. Each surface designed to do one thing exceptionally well, and to disappear when you don't need it.

Notes#notes

A writing surface that stays out of the way.

Type with the slash key for blocks, the cursor never breaks the rhythm. Saved indicator slips in quietly. Math, code, and callouts handled like first-class citizens.

  • Slash menu

    Headings, callouts, lists, math, code, embeds — all reachable without lifting your hands.

  • Reader-grade typography

    Fraunces titles, 62-character line length, italic emphasis. Notes look like books.

  • Autosave with grace

    No spinners. No 'saving…'. The word Saved appears next to Share, in mono — that's it.

AI#ai

Suggestions, not directives.

Knotree's AI is shaped by one rule: never do the homework for you. It summarizes the page you wrote, recommends tags, links related notes, and prepares flashcards.

  • Auto-summary

    Regenerates as you write, debounced. Never interrupts your typing.

  • Suggested tags

    One-click accept. The AI proposes, you decide.

  • Practice questions

    Sent straight to your review deck. Approved by you, never auto-added.

Study#study

Review with the cards you actually need today.

Spaced repetition built into the core. The daily queue is small, focused, and earned — never an adversarial streak meter.

  • Today's queue

    Always under 30 cards by default. Estimated time visible up front.

  • Pomodoro built in

    25/5 by default, configurable. The timer lives next to the queue, not in another tab.

  • Recall scoring

    Four buttons after each card: again, hard, good, easy. Algorithm adjusts intervals automatically.

Homework#homework

Due dates handled without dread.

A clean list, a progress bar, a warm chip when something's due. Teachers create assignments; students complete them. No more spreadsheets.

  • Three states

    Not started, in progress, submitted. Visible at a glance, never more.

  • Inline feedback

    Teachers comment directly in the doc. No PDFs flying back and forth.

  • 24-hour nudge

    A single quiet reminder before each deadline. Configurable. Never harsh.

Library#library

Every doc on one shelf.

Upload PDFs, paste links, or clip articles. Reader mode renders them at the same width as your notes — books and notes look like neighbors.

  • Semantic search

    Search 'eigenvector' and find both the note and the chapter that mentions it. One result, two surfaces.

  • Web clipper

    Browser extension imports articles cleanly. Highlights stay linked back to the source forever.

  • Collections

    Group by course, by reading list, by mood. Color-coded. Optional.

FIG. 05 · Library

And quietly underneath

An accessible, fast, opinionated reading product.

WCAG 2.2 AA across every surface. Respects prefers-reduced-motion. Renders at the same width on every screen. The work isn't the features — it's the thousand small choices that make them feel inevitable.
