Irakasi is an infinite board for working with any kind of information. Lay out everything you have about an idea however it makes sense to you, and work through it with all of it in view. Animate the board to see how the idea changes over time, whether you are working it out for yourself or explaining it to someone else.

On an Irakasi board you can:

• Add any kind of content: text, documents, code, drawings, diagrams, photos, videos, audio, PDFs, tables, web pages, and any other file.
• Work with the AI app you already use, such as Claude or Codex, on your own subscription. It sees the board and changes it with you.
• Edit content without leaving the board, for example to reshape a vector path or paint over a photo.
• Animate the board to show how things move and change, with tools built for understanding an idea step by step.
• Play, present, and export the board, with exports to video, GIF, or PDF files.

Start without an account

Open Irakasi and start working. The first time you visit, Irakasi creates a board for you and saves it in this browser. You don't need to sign up or install anything.

What you can do with Irakasi

Add any kind of content

Everything on a board is a shape, and there is a kind of shape for each kind of content:

• Text and code: text for words and titles, rich text documents with headings and lists, text on a path, and code with highlighting.
• Drawings and diagrams: geometric shapes, paths drawn point by point, freehand strokes, and arrows that stay attached to the shapes they connect.
• Pictures, video, and sound: images, videos that play the part you choose, and audio cards with a waveform.
• Documents and data: PDFs you read and annotate on the board, tables with spreadsheet formulas, and any other file kept as a file card.
• Live web content: web pages shown inside a shape, and HTML shapes: small web pages, such as a calculator, a chart, or a quiz, that run on the board.
• Frames and cameras: frames hold shapes and carry them along when they move, and cameras frame an area of the board to present, animate, or export it.
• Bring your existing work: insert tldraw and Excalidraw files, or paste Mermaid diagrams, spreadsheet cells, and Markdown. They arrive as shapes you can edit.

Work with the AI app you already use

With your own AI subscription, you can connect a board to an AI app such as Claude, Codex, Cursor, or Gemini. The assistant sees the board and works on it while you watch:

• Build the board together: it reads the board's shapes, cameras, and animations, and creates or changes them when you ask.
• Rework anything by hand: what it builds is made of ordinary shapes and animation blocks, so you stay the author of every part.
• Ask for motion pieces: leave your notes, pictures, and recordings on the board, and ask for a launch promo, an explainer, or a narrated clip. You approve the still scenes before it animates them. See Motion pieces.
• Use your own plan: the assistant runs on your AI subscription, and Irakasi doesn't pass your board through its servers to reach it. See Privacy.

Edit content without leaving the board

These tools work right where the content sits on the board:

• Edit vector drawings: move points and curves, combine outlines with boolean operations, and convert SVG pictures and texts into shapes you can edit.
• Retouch pictures: paint, erase, blur, liquify, and select parts of a picture, on layers, with the image editor.
• Edit sound: cut, record, and add effects with the audio editor.
• Make media lighter: media optimization shrinks pictures and videos so a board opens faster, and enlarges pictures with AI.
• Add visual effects: masks hide part of a shape, shape filters change how it's drawn, and camera filters change everything a camera films, from color grading to distortions.
• Place icons: the icon library adds ready-made icons in the size and color you choose.

Animate the board

Animation makes the board change over time, so you can see how an idea develops step by step:

• Move shapes: send them along paths you can edit, and turn, grow, or resize them.
• Record a movement by hand: with Capture Real-Time, drag a handle and the shapes follow it. Your movement and its timing become the animation.
• Reveal and hide shapes: fade them in and out, draw their outlines, type text, or show a series of texts.
• Animate any setting: change colors, stroke widths, styles, and other settings over time.
• Direct the cameras: switch between cameras and zoom them.
• Play videos and sounds: start videos and sounds at the right moment.
• Add pauses: stop the animation where a step needs time to sink in. Pauses matter in any animation made for understanding, so Irakasi keeps them apart from the motion: you can add or move one without shifting the rest of the animation, which most animation tools make you do by hand.

Play, present, and export

When the board is ready, you can play it, present it, or turn it into files:

• Play it in Player mode: switch to Player mode and the editing tools give way to playback controls. Play the animation, pause it at any moment, and zoom and pan around the board.
• Present it step by step: when the animation has pause markers, Player mode stops at each one until you continue, so you can talk through each idea at your own pace. See Step-by-step playback.
• Export it: save the board, or the area a camera frames, as pictures, videos, GIFs, or PDF files. See Exports.

Keep your boards

Your work is saved as you go, and you can keep several boards and variants of each one:

• Saved in your browser: local boards save automatically on this device. Clearing the browser's site data deletes them, so download the ones you want to keep as .irakasi files.
• Many boards: keep several boards and switch between them from the Boards list.
• Variants of one board: Versions keep variants such as a translation, while everything you don't change stays shared.

Your first steps

Start with these pages to find your way around the editor:

• Interface: how the editor's screen is organized and how its controls work.
• Modes: switching between building, animating, and previewing a board.
• Navigation: moving around the board and zooming in and out.
