Edit PDFs, build spreadsheets, write documents, design on an infinite canvas, take notes, and automate the busywork — all in one beautifully fast desktop app, with AI woven through every surface.
Stop juggling a PDF tool, a spreadsheet app, a word processor, a slide deck and a design board. Each surface is a full, focused editor — and AI works across all of them.
Edit real text, fill & sign forms, merge, split, redact securely, OCR scans, and convert to Word or Excel — pixel-accurate.

Explore Spreadsheets →A clean block editor — headings, shapes, banners, templates — with AI that drafts, rewrites and restructures inline.
Explore the Doc editor →An infinite board for diagrams, charts, slides and graphics — with AI layouts, palettes, magic-resize and vector art.
Explore the Canvas →A full presentation editor — themes, layouts, transitions, speaker notes and presenter view — with AI that designs whole decks from a prompt.
Explore Slides →A OneNote-style space — notebooks, wiki-links, fast search, and a roundup of every open to-do across your notes.
Explore Notes →Agentic, repeatable pipelines that transform data and documents at scale — run on a schedule or trigger on demand.
Explore Workflows →Not watered-down viewers — full, focused editors. Here's what each one does.
Open a PDF and change the actual text — fonts, spacing and layout stay intact. No re-creating from scratch.
The full grid you expect — then ask AI to clean, transform, summarize or chart your data on command.
A clean block editor for everything from quick memos to polished reports — and AI that drafts and rewrites right where you work.
Design diagrams, charts, slides and social graphics on a free-form board — with deep AI that can generate whole layouts and vector art.
A full presentation editor: a deck of slides with themes, layouts and transitions, plus a real presenter view — and AI that can draft an entire deck from a prompt.
A OneNote-style space that keeps your thinking organized — and surfaces every open to-do across all your notebooks.
Build agentic pipelines that transform data and documents at scale — then run them on a schedule or trigger them on demand.
Invite anyone to any document — PDF, spreadsheet, doc, canvas or slides. They get an email, you both work on the same file, and every change is tracked and safely merged.
Share by email or a private link, choose who can view, comment or edit, and collaborate across every editor in the app — with comments and history that keep everyone in sync.
Open what you've got, edit it, and send it back out in the format anyone can use. Native IO formats keep your richest work intact.
Ask in plain language. IO Lumen Doc routes your request to the right surface, runs it on a fast frontier model, and bills it transparently against simple credits — the same AI works everywhere you do.
The tools you'd otherwise pay for separately — and switch between all day — are one fast, local app with shared AI.
The entire editor is yours at no cost. The only thing that ever costs anything is AI — and only if you choose to use it.
The whole editor is free, with 300 AI credits every month. Want more? Pick a monthly plan — it refills your credits automatically, and you can cancel anytime.
Your contracts, statements and drafts never leave your machine unless a task needs it. Redaction actually removes data — not just hides it.
Yes. Every editor — PDF, spreadsheets, documents, canvas, notes and workflows — is free forever, with no watermarks or locked features. The only thing that ever costs anything is optional AI, which runs on credits. You get 300 free credits every month.
No. IO Lumen Doc is a desktop app that works on your local files — they stay on your disk. When you use an AI feature, only the specific content that request needs is sent to run it, and every AI action is metered and shown to you.
Credits are how AI usage is metered. You get a fresh free allowance of 300 every month. Need more? Subscribe to a monthly plan (Starter, Plus or Pro) and your credits refill automatically each month. Plans are month-to-month — cancel anytime from your account, no lock-in.
Yes, anytime. Sign in on this site, open your account, and click Cancel — your plan stays active until the end of the period you already paid for, then it simply stops renewing. No emails, no hoops.
