Edit PDFs, build spreadsheets, write documents, design on an infinite canvas, 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 and a design board. IO Lumen Doc brings them together — and lets AI work across all of them.
Edit real text, fill and sign forms, merge, split, redact securely, OCR scans, and convert to Word or Excel — pixel-accurate and fast.
A full grid with formulas, formatting, charts and highlights — plus AI that cleans, transforms and explains your data on command.
Write with a clean block editor — headings, shapes, banners, templates — and let AI draft, rewrite and restructure right where you work.
Design slides, diagrams, charts and graphics on a free-form board with AI layouts, palettes, magic-resize and vector generation.
Build agentic, repeatable pipelines that transform data and documents at scale — run them on a schedule or trigger them on demand.
One assistant that understands your whole document — summarize, extract, edit and automate, across every surface, with metered credits.
Each one is a full, focused editor — not a watered-down viewer. Switch instantly, and let AI work across all of them.
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 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.
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 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. AI runs on credits — you get a fresh allowance every month, and can buy more anytime. No subscription, no lock-in.
Your contracts, statements and drafts never leave your machine unless a task needs it. Redaction actually removes data — not just hides it.
