Your library
Searches every PDF, sheet, document, board, deck, note, form and app you already have, opens the right one, and cross-references between them.
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, in the real editors, and hands back files you can keep changing.
Included on every plan, including free. Agent runs draw on your monthly AI credit allowance; your plan sets the engine and the allowance.
You never choose an app. Pick any goal below and watch which editors and services Agent routes it through — and what you're left holding at the end.
Nothing happens invisibly. Every run is a plan you can read, a timeline you can watch, and a set of files you can open — with your approval standing between the plan and anything consequential.
Six sources of context, each turned on by you. Nothing here is enabled quietly, and every one of them can be switched back off.
Searches every PDF, sheet, document, board, deck, note, form and app you already have, opens the right one, and cross-references between them.
Reads and writes inside the folders you grant it — including watching a folder so new arrivals get handled the same way every time.
Searches the live web and fetches specific pages when a job needs current information, and tells you which sources it used.
Looks at what you're looking at when you ask it to, so “fix the alignment on this slide” means the slide in front of you.
Google Drive, Gmail, Calendar and YouTube — each approved separately, with read and write kept apart, and revocable at any time.
Point it at a Model Context Protocol server and its tools join the same run, used alongside everything above.
Agent is not a separate app with its own file format. It drives the same tools you use by hand, so anything it makes is something you can keep editing.
An assistant that can open your files, spend credits and send email needs limits you set rather than limits it chooses. These are those limits.
Dictate a goal instead of typing it, and have the answer read back. Useful when your hands are on the document rather than the keyboard.
Lumen Mobile runs a quick cloud Agent chat on its own, or hands the turn to your paired desktop — which has your files — and streams the result back into the same conversation.
Preferences and past work carry between conversations, so the way you like proposals structured or sheets formatted doesn't need re-explaining every time.
Your plan decides how deeply Agent reasons. Short, mechanical jobs finish on the fast engine; long autonomous runs across many files are what the deeper engines are for.
No. Reading your own library is routine, but anything consequential — renaming, reorganizing, overwriting, deleting, sending an email, publishing a link — stops and waits for your approval, whatever permission preset you're using. Every AI revision also saves a checkpoint of the state it started from, so you can put a document back exactly as it was.
Ordinary editing happens on your own disk. Content leaves your device only for the cloud step you asked for — an AI action, a share, a connector call — and only the content that step needs. Local files stay local unless you choose otherwise.
Agent runs draw on the same monthly AI credit allowance as the rest of Lumen. Every account gets free credits each month, and you can cap what a single run is allowed to spend. When a run reaches your budget it stops and reports instead of continuing.
Only if you connect it, one service at a time. Drive, Gmail, Calendar and YouTube are approved separately, read and write permissions stay apart, sends and publishing remain reviewable, and you can disconnect from Lumen or revoke from your Google Account at any time.
Yes — connect a Model Context Protocol (MCP) server and its tools become available in the same run, used alongside your library, the web and the Lumen editors.
The run stops at that step rather than guessing past it. You can retry that single step, change the plan, or cancel — the work already completed stays. An interrupted session comes back where it was.
Free to download, free to use. Every account starts with monthly AI credits.
