  • Vector Design

    Built with everything a vector design tool should have: bezier pen paths, boolean shapes, gradients, layers, and auto-layout for real interfaces. Design together with your team, live, and turn any set of frames into a presentation with a built-in player. Bring in an AI agent to build out a layout or add a feature that's missing, then remix the whole thing when you're done.

  • Guitarro

    A chromatic guitar tuner that listens through your mic. Pick your input device, play a string, and the needle goes green when you’re in tune — standard tuning E A D G B E, with a live Hz / cents readout and Rocksmith-style per-string lights; strum a chord and it names it (Am, G7,

  • Writer

    All the word processing essentials: styles, headings, page layout, citations and bibliography, track changes, and comments. Write in the same document together with your team, live, with tracked changes and threaded comments built right in. An AI agent can draft, edit, or restructure it with you, then remix it into something new.

  • Presenter

    It's got the full presentation toolkit: slide design, transitions, animations, tables, charts, icons, 3D models, and a fullscreen slide show. Build decks together with your team, live, with comments built right in. Bring in an AI agent to draft, restyle, or reorder a whole deck for you, and remix the whole thing when you're done.

  • Workbook

    Built with everything a spreadsheet tool should have: formulas, pivot tables, charts, conditional formatting, data validation, and sorting and filtering. Work the same sheet together with your team, live, with comments built right in. An AI agent can build models, clean data, or chart results with you, then remix it into something new.

  • Stride

    One live project behind five views, overview, board, list, timeline with the critical path, and calendar, so your whole team always sees the same plan. Tasks carry owners, dates, priorities, and custom fields, with saved views and a public intake form to catch new work as it comes in. Hand a task to an AI agent and it reads your team's charter, does the work, and hands back a proposal, one click to approve, one click to undo.

  • Video Studio

    A collaborative motion canvas, an infinite workspace where video, audio, vector shapes, pen and pencil drawings, and text are all objects mapped onto a pro multi-track timeline. Auto-keyframing animates anything you move at the playhead; the Stage is just a frame on the canvas, and any frame can become the Stage. Build, animate, and edit together in real time, then export or remix the whole scene.

  • PDF Annotator

    Everything you'd expect from a popular PDF reader and annotation tool: markup tools, shapes, notes, comments, and signatures. Mark up the same document together with your team, live. Let an AI agent handle the summary or the annotations, then remix it into something new.

  • Collaborative Board

    A realtime FigJam-style whiteboard — sticky notes, connectors, live multiplayer cursors and a presence list, all synced over host.collab (Yjs + ReactFlow). Open it and share the link; everyone edits the same board live.

  • Tank Arena

    Command a tank in a fast 3D arena and battle up to eight players at once. Smash through destructible cover, grab weapon crates for machine guns, splash rockets, and proximity mines, and climb the leaderboard one match at a time. Go free-for-all with respawns, or team up to defend your core against endless waves. Jump into a public arena, invite friends with a room code, or roll solo against the bots that keep every match full.

  • N
    Notes

    A notebook with everything you'd want: rich pages for headings, tables, code, and images, backed by a full canvas on every page for shapes and freehand sketches. Link pages together, edit live with your team, and roll back to any earlier version. Bring in an AI agent to read the notebook and propose edits, then undo the whole run in one click if it's not quite right.

  • Files

    A fast two-pane workspace for your whole library: browse, move, copy, rename, upload, download, and open any project in a click. Drag between panes, filter as you type, and preview without opening. Nothing moves or opens without your permission.

  • Bombers

    Realtime multiplayer bomberman: 2 to 4 players on a neon grid. Drop bombs, blow up bricks, grab power-ups (extra bomb, bigger blast, more speed) and be the last one standing. Open it, share the link, and blast live, no setup, no waiting. Plays solo too, and an agent can join in.

  • Nom-Tac-Toe

    Tic-tac-toe with a twist: bigger pieces eat smaller ones, yours or theirs. Line up three to win, but lift the wrong piece and you might hand a rival the row they needed. No peeking under the stacks, so memory matters as much as strategy.

  • Quantum Tic-Tac-Toe

    A mind-bending twist on the classic: every move lands in two squares at once, tangling the board until a loop forces a collapse and your opponent picks which version becomes real. Easy to learn, endlessly clever. Play a friend live or practice solo.

  • Timer

    A simple pomodoro-style countdown timer: start, pause, or reset it whenever you need. When it goes off, everyone else in the room gets the alert too, so your whole team stays on the same schedule.

  • Robongus

    A bite-size social-deduction party game: gather in a lobby by code, walk a little 2D map, finish tasks, and find the impostor before they pick everyone off. Getting caught doesn't end your game, it flips you to the other side, and you choose whether to keep playing that character yourself or hand it to your own AI. The impostor might be human, might be AI, and you won't know which until it's too late. Realtime multiplayer, playable solo against bots too.

  • Multiplayer Tic-Tac-Toe

    Two-player tic-tac-toe with shared game state and live cursor presence. Demonstrates `host.collab` durable Yjs Map state + ephemeral awareness in one widget — the reference template for any multiplayer game or shared form.

    One screen per day of a conference week. Every event you chose, in order, with the travel between them, the clashes and the free stretches worked out on the timeline itself. Built on the public SF Tech Week calendar (1,639 events across 45 neighborhoods), it works offline, and yo

  • Sheet

    A collaborative spreadsheet with the familiar Excel or Google Sheets feel: live editing with your team, around 300 built-in formulas, conditional formatting, and charts. It also runs real Python and JavaScript right in a cell, spilling results across the grid or drawing a chart automatically. Opens your existing .xlsx or .csv files, and an AI agent can make edits alongside you.
