Your PDFs, spreadsheets, docs, slide decks, designs, videos, forms and notes — all in one friendly app. Just ask, and AI fixes the formatting, crunches the numbers, writes the draft, designs the deck and even edits the video — or hand the whole job to your own AI agent. ✨
This isn't a chatbot bolted on the side. Type what you want in plain English and watch it happen — right inside your document. These two are real, unedited screen recordings.
…and the same AI helps you across every other tool, too 👇
No more bouncing between a PDF tool, a spreadsheet, a word processor, a slide-maker, a video editor, a form builder and a design app. Each one here is the real deal — and the same AI helps you across every single one.
Edit real text, fill & sign forms, merge, split, redact securely, OCR scans, and convert to Word or Excel — pixel-accurate.

Beyond the in-editor assistant, IO Lumen Doc has an autonomous AI agent. Describe a goal in plain language and it plans the steps, searches the web, works across your files and connected apps, and builds the result — remembering what matters and asking before anything sensitive, while you watch every move.
Give it a goal — “pull last quarter's numbers into a sheet, chart them, and draft a one-page summary” — and it runs the whole job, step by step.
Invite anyone to any document — PDF, spreadsheet, doc, canvas or slides — or publish a view-only link that opens right in a browser. Collaborators 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. The same Lumen AI works across every surface — PDF, Docs, Sheets, Slides, Canvas, Video and Forms — and can search the web and remember what matters. It routes your request to the right place and bills it transparently against simple credits. Your plan determines which engine you get, and every engine is powered by leading frontier models.
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 app is yours free, with 300 AI credits every month. Want more AI? Pick a personal plan — or cover your whole household or team with a Family or Business plan. Credits refill automatically, and you can cancel in one click.
Cover your whole household or team with pooled AI credits and a single bill. Invite people, manage seats — and everyone gets premium Lumen AI.
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 — Plus, Pro or Max, or a Family or Business plan — 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.
Yes. A Family plan covers up to 5 people (Family Max up to 8) with a shared pool of AI credits and one bill. For work, Team and Business plans are billed per seat with pooled credits and central seat management, and Enterprise adds SSO and invoicing. Everyone on a plan gets premium Lumen AI — invite and manage members right from your account.

Yes. Share any document — PDF, spreadsheet, doc, canvas or slides — by email or a private link, and choose whether people can view, comment or edit. You collaborate with comments, version history and automatic conflict-safe merging; people you invite get an email notification. Shared documents are encrypted at rest, and you can change roles or revoke access anytime.
The IO Agent is an autonomous assistant. Give it a goal in plain language and it plans the steps and carries them out across your files — reading your library, transforming data, and creating documents, sheets, slides, reports and widgets. You see a live timeline of every step it takes, and it asks for approval before anything sensitive like renaming or reorganizing your files.
Yes. From any editor you can publish a view-only web link that opens in any browser — no app or account needed to view it. Choose public or restricted access, optionally allow downloads, and revoke the link whenever you want. The document is decrypted server-side only to render the page; your keys never reach the browser.
Yes. Open PDFs, Word documents, Excel workbooks, PowerPoint decks, CSV/TSV data and images, edit them, and export back to the formats other people use. Your richest work can also be saved in native IO formats.
Yes. Lumen Forms builds forms, surveys and polls — every question type, plus photo and video statement blocks and real file-upload answers. Publish a form to a web link anyone can fill in (no app or account needed), keep an audience of contacts and groups, email it out, and resend to anyone who hasn't replied.
Yes. Canvas has a full Video mode: turn a board into a short-form video with an AI director that cuts on the beat, adds kinetic captions, casts a voice-over and scores it. Drop in stock footage or AI-generated clips, then export MP4, WebM or GIF — or publish straight to YouTube and hand off to TikTok, Reels and Shorts.
