Lumen product tour

PRODUCT

One library that

remembers for you

Four parts that work together: capture from anywhere, connections by meaning, a daily review that sticks, and search that understands what you meant.

Daily review

01 · CAPTURE

Save from anywhere in a second

Lumen meets you where the idea shows up: a page in your browser, a PDF on your desk, a thought on a walk. Everything lands in one inbox with its source attached, ready to be found later.

The browser clipper keeps the source, author and date

Voice notes are transcribed and tidied for you

Forward any email to your private Lumen address

02 · CONNECT

Ideas find each other on their own

Lumen reads what each note is about, not just the words in it. A podcast quote, a book highlight and your own half-formed thought end up side by side when they make the same point.

Related notes appear on every note you open

See whether a note agrees with, contrasts or illustrates another

Threads form by themselves as a topic grows

03 · DAILY REVIEW

Two minutes a day, and nothing slips away

Each morning Lumen picks a few notes you have not seen in a while and spaces the repeats, so good ideas come back right before you would have forgotten them.

Five notes a day, or as many as you choose

Keep it, snooze it for a week, or let it go

Star the ideas you never want to lose

04 · SEARCH

Search the way you remember

You rarely remember the exact words. Describe the gist and Lumen finds the note you meant, then shows how closely each result matches.

Type the gist instead of exact keywords

Narrow by source, thread or date when you need to

Every result shows why it matched

AND THE REST

Small things that add up

PDF highlights

Highlight papers and books; page numbers come along.

Voice notes

Talk it through; get a clean transcript and summary.

Email forwarding

Send newsletters and threads to your private address.

Browser clipper

Save a page, a paragraph or a single quote.

Share from your phone

Use the share sheet in any app to send it to Lumen.

Works offline

Capture on a plane; it syncs when you land.

Export anytime

Your whole library as Markdown, whenever you want it.

Private by default

Nothing is shared unless you share a thread.

DARK MODE

Easy on the eyes

after dark

True black surfaces, calm violet accents and type that stays readable at midnight. Lumen follows your system setting, or picks a side when you ask it to.
