Three tools presenters juggle.
One studio.
You'd normally need an animation tool for the motion, a polling app for the room, and a chatbot tab for the AI. Tchaku is all three — and the polls are slides, not a separate app.

Polls, quizzes, word clouds — as slide types. The room joins by QR on their phones; results animate in live.

The deck app that does what your deck actually needs.
The editor
A canvas built for motion and data.
Drag, snap, align — then keyframe. The same canvas handles a bar chart, a SWOT, a funnel, an org chart, and a 3D-flip title build, with a timeline below that animators will recognize.
- 40+ chart & infographic types — bar, line, donut, funnel, org chart, mind map, SWOT, branch hub
- 12 motion effects — path, 3D flip, physics, morph, glitch, typewriter and more
- Local-first .tch files — decks live on your machine, not in someone's cloud
Tchaku
Live audience
Polls, quizzes, word clouds — as slides.
Insert a Live Poll, Quiz, Word Cloud, Leaderboard, Scale, Ranking or Open-ended slide from the picker. The room joins by QR. Answers stream in mid-deck and animate onto the stage. When you advance the slide, the session ends — clean.
- Seven live-audience slide types — poll, quiz, word cloud, leaderboard, scale/rating, open-ended, ranking
- QR-only join — no account, no app install — your audience just scans
- Scoring + leaderboard — live quiz keeps score; the leaderboard is its own designed slide
Tchaku
AI generation
Describe the slide. Get the slide.
Tell Tchaku what you want. Claude drafts layout, copy, colors and animation as actual editable elements — not an image — plus AI images, narration and 3D models. Tweak anything afterwards; it's just a slide.
- Slides, charts, images, voice & 3D — describe it; it drafts as editable elements
- Multi-model under the hood — Claude · gpt-image-2 · OpenAI TTS · Meshy
- Credit-metered — no keys to manage — every plan includes monthly AI credits

FAQ
Honest answers.
If something's still unclear, the README in every deck export answers it too.
The editor is free forever — animation, live polls, quizzes and word clouds, Apple Pencil ink, the presenter camera and talk recording, plus 30 AI credits a month. Paid plans add more AI credits, premium pen tools, viewer analytics on share links, the premium infographic layouts and every export format.
On your machine. Tchaku is local-first: a deck is a .tch file you can open, copy, version-control or move offline. Deck content reaches a server only through actions you take — a share link, a live session, or an AI request.
When you hit Present on a live-audience slide, Tchaku shows a QR + short URL. The room scans, answers in their browser (no install, no account), and their responses animate onto the slide. Advance the slide and the session ends.
AI is metered in credits — every generation (a slide, image, narration or 3D model) draws from your monthly balance. Free includes 30 credits, Pro 400, Studio 1,500. Roughly one credit ≈ one AI slide. No API keys to manage.
Yes — the full editor runs natively on macOS and Windows, and in your browser. Same local-first files everywhere. A native Linux build is still in progress.
Yes — the editor, AI generation aside, has no network requirements. Live audience sessions need a connection (the audience is on their phones), but the deck itself works offline.
Live annotation is powered by the Tchaku Pen companion for iPad + Apple Pencil — pair it over your local network and draw on any slide while you present; strokes appear on the Mac and projector instantly and save into the deck. The Mac editor and everything else works fully on its own; the iPad app is the pen surface.
Yes — import .pptx directly, and export back to PPTX, PDF, PNG or a shareable HTML link. Tchaku fits whatever your team already uses.
Your next talk deserves a room that talks back.
Free includes the full editor, all motion, and every live audience type.
