Using Canvas

Overview

Canvas is an infinite spatial workspace for AI filmmakers and professional creators. On a single board you can generate and edit images and videos, lay out storyboards, build editable pitch decks and demo websites, review work with your team, and share preview links with your customers — all in one browser tab, with everything kept exactly where you or a collaborator left it.

Open it from the Canvas tab in the top navigation, or go straight to letz.ai/canvas. Canvas requires an active paid subscription. The AI Assistant draws from your Credit balance.

This guide covers the main features. When you're ready to work faster, keep the full shortcuts reference close by.

Inviting users

Canvas is collaborative in real time — you can see everyone's cursors and presence avatars in the top bar, and changes sync instantly.

Add collaborators

Click Share in the top-right of the board to open the collaborators panel. Search for a user by username, pick a role, and add them:

Role	Can do
Owner	Full control, including managing collaborators and deleting the board.
Editor	Generate, edit, move, and arrange everything on the board.
Viewer	View-only — can navigate, zoom, present, and comment, but not edit or generate.

You can change a collaborator's role or remove them at any time from the same panel. Owners can also share a board with an entire organization, so every member gets access automatically. If someone opens a board they can't access yet, they can request access, and the owner approves it from the Share panel.

Share previews with customers

To share work outside the team, publish a section or design and send a link on preview.letz.ai — a dedicated preview surface where stakeholders can watch and react without opening the editor or creating an account. Share the cut, not a zip file.

Moving elements & tools

The board is an infinite stage. Pan with the Hand tool, Space + drag, or two-finger scroll. Zoom with ⌘ / Ctrl + scroll or pinch. Press ⇧1 to fit the whole board in view and ⌘0 to reset to 100%.

Tools

Press a letter to switch tools (when you're not typing in a field):

Key	Tool
V	Select — move, resize, and multi-select
H	Hand — pan the board
T	Text
R O L A	Rectangle, Ellipse, Line, Arrow
P	Pen — freehand strokes
S	Section — a generation surface (dashed outline)
F	Frame — an empty designable rectangle (solid outline)

Moving & arranging

With the Select tool, click to pick a node and drag to move it. Drag the handles to resize, or hold K for proportional (scale) resize. Hold ⌥ and drag to duplicate. Nudge with the arrow keys. Standard editing applies everywhere: ⌘Z to undo, ⌘C / ⌘V to copy and paste, ⌘D to duplicate, ⌘G to group a selection into a section.

Bring your own content in by dragging files from your desktop onto the board, pasting from the clipboard, or pressing M to open your media library. Right-click anywhere for context actions — change the board background color, fit or reset zoom, or open node actions like download, duplicate, and layer order.

Using Chat

The AI Assistant lives in the panel on the right of the board. Unlike a generic chatbot, it reads your layout and respects your selection, so it can work in the context of what's already on the board.

Ask it in plain language to plan a storyboard, generate stills shot by shot, animate panels, build a deck or website, or pull web references onto the board. It can run longer multi-step jobs and shows a live plan as it works.

• Send a message with Enter; add a new line with ⇧Enter.
• Use a reference — select an image on the board first, and the assistant uses it as context for the next request.
• Mention a model by typing @model in your prompt to generate with one of your trained models.
• Search and place — ask it to search the web for references and drop the results straight into your layout.

Everything you already have on LetzAI is reachable without leaving Canvas: drag from your library, paste from the clipboard, or pull from your Boards.

Creating videos, sections & editing on the timeline

Sections

A Section (press S, or group a selection with ⌘G) is a generation surface with its own prompt and a grid of shots. Use it to generate a set of related images — a storyboard strip, lighting variations, or a sequence of shots — and keep them together as one unit you can move and present.

Turning shots into video

Select any image and press A (or use the right-click menu) to animate it into a video. You can re-animate existing videos the same way. Generate shot by shot, animate the ones you want, and arrange them in a section.

Looking through a section

Double-click a section's body — or right-click it and choose Open slideshow — to open a fullscreen lightbox. Every child gets a slide: stills, clips, audio, designs and movies. Step with ← / → or the thumb rail; the sidebar carries comments and colour-coded labels for the slide on screen. There is no timeline here and no video export — a section is a box of things, not a cut. Download all in the header packs every media file in the section into one zip. A design or movie on a slide has a button to open it in its own room (design present, or the movie timeline).

Editing on the timeline

Add a Movie from the bottom toolbar (M), or right-click a section and Promote to Movie. Double-click the movie — or choose Open movie / Edit movie — to open the fullscreen Sequence room. View has a player with a seek bar, volume and loop, and Review for the shot under the playhead. Space plays; the step buttons move by one frame over video and shot-to-shot over stills.

Click the pencil for Edit and the timeline: stacked video rows over audio rows, with trim, split, move, transitions and keyframes. Drag the line between two rows to make one taller, and drag the heavier line to resize the whole video or audio zone. Hold Alt while dragging a clip to drop a copy instead of moving it, and drag it past the top or bottom row to have that track created for you — there is no separate "add track" button. Under the row names sit A for a title and the filled square for a colour card. ⌘Z undoes; ⌘C, ⌘V, ⌘D and ⌘K copy, paste, duplicate and split. A video's sound always arrives as its own clip on an audio track, linked to the picture — Unlink in the sidebar when you want the sound free. When the cut is right, export the video.

Clips on the timeline show the name and thumbnail of the shot they point at, so you can read the cut at a glance; one whose source was deleted, or is still generating, is marked rather than looking like an ordinary clip. Clips on an audio row draw their waveform, showing only the part of the sound they actually play — so the two halves of a split look different, and trimming the head visibly walks into the track. Dragging and trimming snap to the nearest clip edge on any track, to the playhead and to the start — a dashed guide shows what caught, the magnet button (N) turns it off, and holding ⌘ / Ctrl ignores it for one drag. ⇧-click clips, or drag a band across empty track space, to move or delete several at once.

The Media button in the header opens your library — generations, assets, boards and uploads — without leaving the room. What you pick lands on the board as well as in the cut: inside the section you are editing, or on a free spot beside the movie. That matters because a clip points at a board node, so everything in a sequence stays something you can review, regenerate and re-cut.

Selecting a clip also draws a box around its picture on the stage: drag inside it to reposition the shot, pull a corner to resize it, or turn the knob above it to rotate — hold Shift to keep a move on one axis, to scale in 5% steps or to rotate in 15° ones. With auto-key on, each of those drags writes a keyframe at the playhead, which is how you animate a move without typing a single number. The box only appears while the playhead is over the clip and while playback is stopped.

Selecting a clip fills the sidebar with its properties: what it is (the shot it came from, with a thumbnail), where it starts and how long it runs, how it fills the frame, and its volume. Below that, Transform holds position, scale, rotation, opacity and blur. Each of those rows shows the value at the playhead and carries a small diamond — click it to key that value at the playhead, and the row starts animating between keys. Type into a field and press Enter (or click away) to apply it; arrow keys nudge, Shift with them nudges ten times as far. Select a title and a Text block appears: the words themselves at the top, then font, size, weight, colour, background, alignment, line height, tracking, padding and a reveal that types the line out word by word or letter by letter as the clip plays. A colour card gets a colour picker the same way. Format at the top sets the frame size and rate for the whole sequence.

Every sidebar in Canvas — Properties and Review in the Sequence room, Slides and the theme panel while presenting a deck — has a title bar with a chevron that folds it away to a slim labelled rail on the same edge; click the rail to bring it back. Canvas remembers which ones you keep closed. On a phone or a narrow window they start folded and open over the stage rather than squeezing it, so the picture stays watchable.

Creating presentations & editing them

Canvas can build entire editable pitch decks. Ask the assistant to create a deck (for example, "build a 6-slide pitch deck for…") and it generates a multi-slide design on the board.

Presenting

Double-click the design to open it fullscreen in present mode. Step through slides with ← / →, and preview how it looks across device sizes with the device toggle in the header.

Editing

You don't have to regenerate to make changes. In present mode, click the edit (pencil) button to edit copy directly in place. For larger changes, just tell the assistant what to adjust — wording, layout, colors, or a new slide. Compare variants side by side at full size on the board.

Exporting & sharing

Export a design as HTML, PDF, or PNG from the present header or the right-click menu, or publish it to preview.letz.ai to send stakeholders a link.

Creating websites & editing them

The same design system builds working demo websites. Ask the assistant to generate a site — a landing page, a product page, a portfolio — and it produces an interactive design that runs live on the board in its own sandboxed frame.

• Browse it — double-click to focus the design, then scroll, click links, and follow slide navigation inside it.
• Edit it — describe the changes you want and the assistant updates the site. You can also edit copy in place, or open the source files in the Designs panel's code editor for fine control (⌘S saves).
• Preview responsively — switch device sizes in present mode to check desktop and mobile layouts.
• Publish — export the design or publish it to preview.letz.ai to share a live preview link.

Next steps

The fastest way to learn Canvas is to open a board, drop in a reference, and ask the assistant to build something. When you want to move faster, keep Canvas Shortcuts handy for every keyboard and right-click action.
