Built for teachers, tutors & lecturers

Mark up, teach and think on one endless canvas

Educator Canvas turns any PDF into a live teaching surface — pressure-sensitive ink, real text markup, audio notes, an AI study assistant, and an infinite scratchpad beside every page.

A complete annotation studio

From a quick highlight to a fully re-built document — every tool an educator reaches for, on a canvas that never runs out of room.

Pressure-sensitive inking

Low-latency stylus ink that thickens with pressure. Pen, highlighter and calligraphy nib, each with its own colour, width and opacity.

Smart shapes

Draw freehand and hold — your stroke snaps to a clean line, rectangle, ellipse, triangle or arrow. Handwriting is left untouched.

Whole & partial eraser

Wipe an entire vector stroke, or trim just the segment you touched. Right-click is an instant eraser on desktop.

Real text markup

Highlight, underline, squiggly, double-underline and strikethrough that snap to the actual words — text stays readable the whole time.

Stamps & signatures

Reusable stamps and hand-drawn signatures you place once and reapply anywhere, plus page-anchored sticky notes.

Sticky notes

Editable, draggable notes pinned to a page and saved with the document — perfect for feedback and reminders.

Audio notes

Record a spoken comment right onto a page and play it back in-app — perfect for feedback and flipped lessons.

Pin images

Drop images onto any page coordinate, drag and resize them, and keep them saved with the document.

Presentation laser

A glowing, auto-fading laser pointer that leaves no permanent ink — colour and size to taste. Great for live teaching.

Dual workspace

Two PDFs, side by side — both fully annotatable

Compare a source and a worksheet, a question and a mark-scheme, or last year's paper and this year's. Each pane keeps its own ink, notes, images and audio. Tap a pane to focus it; the toolbar, knob and shortcuts follow.

  • Shared pool of open PDFs with a Chrome-style tab bar
  • Switch between PDF + Canvas and Dual PDF modes
  • Connected page-notes follow whichever PDF you're viewing
  • Split ratios and a draggable divider

Room to think beside every page

Work through a problem without ever cramping the margins. The canvas extends downward as you write, pinch to zoom, and remembers a separate space for each page of your document.

  • Auto-extending canvas — keep writing, it keeps growing
  • Pinch-to-zoom and two-finger pan on tablets
  • Planner backgrounds: dot grid, Cornell, music staff, isometric, lined & dark
  • Palm rejection — rest your hand, write with the pen, scroll with a finger

Bring your own key

An AI teaching assistant, on your terms

Connect your own OpenAI, Gemini, Claude or DeepSeek key. Nothing is sent anywhere until you ask — every AI action is consent-gated, and your key lives in your device's secure keychain.

Summarize & rephrase

Condense a passage or rewrite it at a different reading level in a couple of taps.

Define & translate

Instant definitions and multi-language translation for any selected text.

Grammar correction

Clean up syntax and grammar in your notes and text markups.

Send selection to AI

Lasso any region and send the image plus your own instruction to a vision model — insert the reply straight back as a note.

Generate images

Describe a diagram or illustration and pin the generated image onto the page.

Private by design

Keys stored in the OS keychain, never in plain text. Per-action consent before any document content leaves the device.

Beyond annotation

Real document & workflow power

Educator Canvas is a full PDF workspace, not just an ink layer.

Document builder

Reorder, rotate, delete, insert blank pages and merge PDFs — then save a fresh file.

Search & navigate

Full-text search with find-next, an annotations panel, page jump, and continuous / two-page / single-page views.

Flexible export

Flatten ink into an image PDF, keep text selectable with vector export, export canvas or a side-by-side spread, or annotated pages only.

Display overlays

Invert colours for comfortable dark reading, or drop a grid over the page.

Tagged library

A multi-tag document library with search, recents and pinned docs — no rigid folder tree.

NextCloud / WebDAV sync

Push and pull your annotations through your own NextCloud or WebDAV server with an app password.
