Everything the board does, and nothing it pretends to.
One build, nine capability areas, five platforms. The panel is the flagship surface, not the boundary — every behaviour below is in the shipping product on all of them, written the way it actually works in a room so your technical team can check us on it.
An infinite chalk field, three inks deep.
The board is always light and the chrome is always dark, so a room reads the work and not the interface. Slate, amber and red on chalk — a closed palette chosen for distance legibility, with tints for fills and nothing else. Pan and zoom are free; line weight never wobbles.
- Pen, highlighter, chalk nib and eraser
- Highlighter draws at twice the line, at 30% ink
- Pressure honoured where the panel reports it
- Eraser grows while held; single touch only
Drafting tools you can shove out of the way.
Ruler, set square, protractor and compass are objects on the canvas, not dialogs. Drag them where the hand is, draw along the edge, flick them off the board when the moment passes. They live on the display and are never saved into anyone’s board.
Straight lines and measured marks, rotatable to any angle.
Right angles and 45° work without measuring anything.
Angles read out live as the arm swings.
Circles and arcs at a fixed radius, drawn by hand.
Shapes, notes, text, connectors.
Pickers place an object and hand straight back to Select, so the next stroke never waits for a mode change. Sticky notes take typing the moment they land. Connectors follow the shapes they join. Selection chrome stays the same size at any zoom, so a handle is always a handle.
Type the moment it lands — no dialog, no cursor hunt.
A running order, drawn on the board.
Draw a frame around anything and name it. Present mode hides every control and steps the room through the frames in order, the camera moving on the brand’s 220ms ease. Nothing is exported and nothing is converted — the board itself is the deck.
The assistant that asks permission.
This is the AI part, and it is deliberately unexciting: circle something, ask a question, get a proposal anchored where you asked. Nothing lands on the board until a human accepts it, nothing is drawn outside a proposal, and the assistant cannot act on its own.
A transient loop, drawn in the assistant’s own dashed line — never ink, never saved.
3 × 24 = 72
Because 3 × 20 = 60 and 3 × 4 = 12.
Marked, anchored, and outside the board’s content until someone says yes.
It becomes ordinary board content — editable, erasable, with no permanent badge.
Dictate a prompt instead of typing on a wall. Speech is turned into text and then discarded — no audio is stored.
Join by scanning, not by typing.
A code on the wall and a phone camera is the whole sign-in. Nobody types a password in front of an audience, and nobody needs an account to draw on the board for twenty minutes. Presence is shown as a count you can read from the back of the room.
Scan, or type the code at chalktap.com/join.
- Everyone draws at once; strokes appear as they happen
- The companion app is a second surface, not a remote control
- Offline switches the board to Pan and protects the work
- Board library keeps every session, searchable and duplicable
Play the session back, stroke by stroke.
Replay reconstructs a session from the board’s own stroke history — silent by default, with no camera and no room audio unless someone deliberately turns narration on. The camera follows the writing; scrub, or run it at four times speed.
The people who aren’t in the room.
Rooms puts remote participants in a rail beside the canvas — video where it’s wanted, a shared screen where it’s needed, labelled cursors so it’s obvious who drew what. Same board, same tools, boardroom vocabulary.
Five builds, one board format.
The panel build is the flagship, not the boundary. A board opened on a laptop, in a browser or on a phone is the same board, with the same chrome laws at every width — which is why work started on a wall carries on at a desk without an export step.
See it on a real panel.
We’ll run the board the way your customers will: standing up, at distance, with a room watching.
