Edit a PDF, write a polished document, clean up a spreadsheet, or turn rough notes into something ready to send.
Explore create & edit →Open the files you already have, create what comes next, and keep everything organized in one familiar desktop app. Lumen AI is there when you want help—and stays out of the way when you do not.
You do not need to learn ten separate products. Choose the kind of work in front of you, and Lumen Doc Hub opens the right tools while keeping your files, AI help, sharing and history together.

See desktop and web sharing →Lumen AI works inside the editor, with the document in front of you. It can build, edit, organize and explain—not just suggest what you should do next. These examples are captured from the desktop application.
One prompt. A real result. Across every Lumen workspace.
Choose the focused editor you need without leaving the hub. Each tool shares the same library, familiar controls, AI assistance, autosave, sharing and account.
Edit real text, fill & sign forms, merge, split, redact securely, OCR scans, and convert to Word or Excel — pixel-accurate.

Explore Lumen Sheets →A clean block editor — headings, shapes, banners, templates — with AI that drafts, rewrites and restructures inline.
Explore Lumen Document →An infinite board for diagrams, charts, marketing, posters and boards — with AI layouts, vector art, magic-resize and a brand kit.
Explore Lumen Design →A full presentation editor — themes, layouts, transitions, speaker notes and presenter view — with AI that designs whole decks from a prompt.

Explore Lumen Forms →Give it a goal, review its plan, and watch it complete multi-step work across your library and Lumen tools.
Meet Lumen Agent →Open a group for the details. This is the full desktop, browser-sharing and guest-portal experience—organized by the kind of work it helps you finish.
Work directly with real PDF content while preserving the page, fonts, links, annotations, bookmarks and interactive form fields.

Use a familiar grid for everyday calculations, then move into serious analysis, visual reporting and AI-assisted data preparation when you need it.
Start, find and switch between every kind of work from one home screen instead of managing separate app libraries.
Arrange ideas freely on an infinite Lumen Board or start from a social, marketing, presentation and print-ready format.
Switch a board into Video mode to build social video with a timeline, audio and AI-assisted direction without moving to another app.
Build slides with consistent themes and flexible layouts, or ask AI to turn a brief, document or data set into a complete deck.
Generate a useful starting point, then keep editing every element yourself. AI output remains part of the real document—not a flattened picture.
Organize naturally with notebooks, sections and pages while keeping fast capture, rich structure and search close at hand.
Create a polished experience, send it to the right audience and watch responses flow into analysis-ready data.
Describe a tracker, calculator, dashboard, planner or client portal—or turn an existing Lumen Sheet into one without a separate coding project.
Turn a multi-step job into a reusable automation that can run on demand, on a schedule or when new work arrives.

Invite people from any supported editor and keep comments, access and activity attached to the work itself.
Recipients can view documents, explore dashboards and apps, or answer forms without installing the desktop app.
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 — with AI-native formulas, Goal Seek and Flash Fill — then turn any range into a Power BI-style dashboard, or ask AI to clean, transform and explain your data.
=AI(), =AICLASSIFY(), =AIEXTRACT() fill cells from a promptA clean block editor for everything from quick memos to polished reports — and AI that drafts and rewrites right where you work.
Design diagrams, charts, social graphics, marketing and posters on a free-form board — with deep AI that generates whole layouts, boards and vector art.
Switch any Lumen Board into Video mode and let the AI direct it — beat-matched cuts, kinetic captions, a cast voice-over and a score that lands on the drop. Made for Reels, Shorts and TikTok.
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 — capture it by typing or by voice, and surface 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.
Build a form or poll in minutes, publish it to the web, and collect real responses — including file uploads. Keep an audience of contacts and groups, email your form out, and nudge whoever hasn't replied.
Describe what you need and Lumen Apps builds a focused tool people can actually use — without making you learn code or wrestle with a blank canvas.
Beyond the in-editor assistant, Lumen Doc Hub 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 a Lumen PDF, document, sheet, board or slide deck—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.
Lumen Doc Hub keeps the powerful editing tools on your computer while making the result easy for anyone else to open. Share a document, dashboard, app, form or poll with the right level of access—no confusing handoff required.
Edit locally, work across multiple tabs, use every Lumen tool and decide exactly what leaves your device.
Publish a link that reflects the document clearly, with public, restricted or passcode-protected access.
Guests and collaborators get a friendly library instead of a pile of unrelated links.
Open what you've got, edit it, and send it back out in the format anyone can use. Native Lumen formats keep your richest work intact.
Ask in plain language. The same Lumen AI works across every tool — Lumen PDF, Document, Sheets, Design, Slides, Notes, Apps, Automate, Forms, and Agent — 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 core desktop editors are free to download and use, with no trial timer. Every account also starts with a monthly AI allowance; paid plans add more AI and advanced connected capabilities.
Use the core desktop editors and 300 monthly AI credits on Free. Paid plans increase your allowance and add premium AI, publishing, automation and connected features. Credits refill monthly, 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.
You can download Lumen Doc Hub and use the core desktop editors for local PDF, document, spreadsheet, design, slide and note work without a trial timer. A free account includes 300 AI credits every month. Advanced connected features—including transcription, web form publishing, AI images, connectors and Lumen Automate—depend on your plan.
No. Lumen Doc Hub 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 a PDF, spreadsheet, document, Lumen Board or slide deck 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.
Lumen 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 interactive apps. 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 Lumen project 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. Lumen Design has a full Video mode: turn a Lumen 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.
