Understand canvases Learn when to use a canvas, page canvas, freeform whiteboard, sub-canvas, or project-connected canvas. Learn canvas basics Follow a learning path from creating a canvas to adding elements, comments, sharing, and export. Create a canvas Start a blank canvas, use a template, import content, or create one inside a project. Page canvases and freeform whiteboards Choose the right canvas format for structured pages, slide-style review, or open-ended spatial work. Use canvas templates Start from reusable canvas structures, choose the right template shape, save clean templates, and avoid stale placeholders. Import PDF and Office files Create a canvas from PDF, Word, PowerPoint, Excel, or HWP files and review the converted result with comments and canvas tools. Convert an uploaded document to a canvas Turn a selected PDF or Office file already on a canvas into a connected sub-canvas without uploading the document again. Use sub-canvases Create connected sub-canvases when a large canvas needs focused child spaces, clearer navigation, or deeper work without crowding the parent. Add and select canvas elements Add text, notes, shapes, images, embeds, and files, then select and move them on the canvas. Sticky notes Capture workshop notes, ideas, votes, and follow-ups with sticky notes on the canvas. Text objects Add headings, labels, instructions, and readable annotations that stay directly on the canvas. Shapes Build structure, frames, diagram blocks, highlights, and visual grouping with shapes on the canvas. Arrows and lines Show flow, relationships, callouts, and connections between canvas objects with arrows and lines. Connect objects with smart arrows Use smart arrows on a freeform whiteboard to connect objects, keep diagram lines editable, and give AI Studio clearer previous context. Pen drawings Draw freehand marks, highlights, circles, and review annotations directly on the canvas. Stickers Add lightweight visual markers, reactions, and symbols without turning them into structured canvas data. Use the rich text editor Format text inside canvas objects, spreadsheet cells, comments, and chat with ALLO's shared editing tools. Use the inline toolbar Edit selected canvas elements quickly with the toolbar that appears near the selection. Use the element menu Open the full element menu for actions that depend on the selected canvas item type. Lock canvas objects Use object locks to protect important canvas layout and reference material from accidental edits. Work with images, files, and spreadsheets Preview, edit, replace, download, and manage media, file, and spreadsheet elements inside a canvas. Work with file objects on a canvas Upload, preview, download, review, and troubleshoot files, PDFs, Office documents, and other attachments on a canvas. Work with image objects on a canvas Review, preview, crop, replace, download, remove backgrounds, and comment on image objects without losing their canvas context. Use links and YouTube embeds on a canvas Add website links, rich link cards, and YouTube videos to a canvas, then preview, open, replace, and discuss them safely. Use spreadsheet objects on a canvas Create lightweight tables on a canvas, edit cells, use formulas and functions, add collaborative cell content, and manage row or column actions. Preview canvas objects Open images, PDFs, video, audio, text, CSV, links, embeds, and Office or HWP documents in a focused preview without leaving the canvas. Use the hand tool Pan around a canvas without selecting, moving, or editing objects. Undo and redo canvas edits Use undo and redo safely, understand what history covers, and recover when collaboration changes the result. Use the minimap Navigate large freeform whiteboards, understand the viewport marker, and know why page canvases use the slide rail instead. Canvas shortcuts Use keyboard and mouse shortcuts for tools, selection, dragging, resizing, snapping, drawing, search, and object actions on a canvas. Use canvas pages Add pages, move between them, and structure a canvas for review, documentation, or presentation. Use the page menu Manage page-level actions such as comments, page size, background, sub-canvases, duplication, and deletion. Fold pages Hide page canvas sections without deleting them, then unfold them when they should return to the active flow. Page size Resize one page, selected pages, or every page in a page canvas, and understand how page size affects automatic height, presentation, export, and freeform whiteboards. Use the slide rail and overview Navigate long canvases, reorder pages, and find pages with unread object or comment activity. Search inside a canvas Use Command+F or Ctrl+F to find text in the canvas you are viewing without leaving the canvas. Present a canvas Show a canvas as a fullscreen presentation without the editing interface in the way. Track object activity and unread changes Use hover details, red unread dots, and slide rail counts to see what changed on a canvas. Use the canvas header menu Export, print, rename, restore, back up, open in desktop, or manage whole-canvas settings. Export a canvas to PDF Create a high-resolution PDF from a page canvas for offline review, archive, or handoff. Share a canvas Invite people, create share links, and choose who can view, comment, or edit a canvas. Use a Canvas PIN or passcode Protect a shared canvas with a 4-digit PIN so people need both access and the code before content opens. Manage Canvas members Review who can access a canvas, invite people by email, adjust roles, and choose between direct invites, share links, and private links. Private links and share links in Canvas Understand which Canvas links grant access and which links only send someone to an exact page, object, comment, or chat message. Use the collaboration side panel Review comments, activity, and canvas information from the right-side collaboration panel. Collaborate live on a canvas Use presence, cursors, online status, and follow-style navigation while working together. Collaborate with guests Let external collaborators open shared work with the right guest experience and permissions. Use canvas chat Open Team chat from a canvas, use it for live coordination, and move durable decisions into comments. Use audio/video calls in a canvas Start or join a canvas call, manage call controls, and keep the canvas usable while people talk. Use AI Studio in a canvas Create AI output from a canvas you can edit, use Object Chat, review results, manage credits, and recover failed or pending AI work. Manage canvases in projects Use project and list menus to organize canvases with owners, Due dates, tags, sections, and access. Troubleshoot canvas issues Recover from common canvas problems with access, loading, comments, export, media, or performance. Run a workshop in a canvas Use templates, pages, comments, sharing, calls, chat, and presentation mode to run a team workshop. Fix a failed canvas export Check common causes when PDF, print, image, or file export does not complete as expected. Give feedback with comments and mentions Leave feedback on the exact place it belongs, pull in the right person with a mention, and keep track of what is still open. Mention people and canvas collaborators Use @mentions to bring the right collaborators into canvas comments, chat, rich text objects, and Inbox notifications.
