Field notebook

On slow afternoons in late September

The river was lower than usual and the light fell sideways through the cedars. I left the camera home and tried to write down what I saw — not photographs, just sentences.

Why OtterMind

The calm of a notebook. The depth of a workspace.

Six small things, considered carefully, that add up to a place you’ll actually want to return to.

Write without friction

A clean editor with blocks, markdown, and embeds. Form follows thought.

Keep every file

PDFs, images, audio, code, spreadsheets — all in one place, always at hand.

Organize the way you think

Nested workspaces, databases, and tags. Build a structure that fits you.

Find anything in seconds

Instant full-text search across documents, files, and metadata.

Always in sync

Mac, Windows, web, and mobile. Pick up exactly where you left off.

Share when you’re ready

Publish a page, invite a collaborator, or keep everything quietly private.

How it works

Three steps. Years of clarity.

01

Capture

Drop a thought, drag in a file, paste a link. Nothing is lost in the moment.

02

Organize

Group pages into workspaces, tag them, or let them live in a database.

03

Return

Search, browse, and rediscover what you knew but had forgotten.

Made for

A quiet workspace, fitted to many lives.

For students

Lecture notes that don’t get lost in a folder.

For researchers

A field notebook for sources, citations, and stray ideas.

For writers

Drafts, references, and the quiet space to finish them.

For builders

Specs, snippets, and decisions — all in one workspace.

“It’s the first place where my notes, my files, and my half-formed thoughts feel like they live together.”
Ada L. — researcher, early adopter
