Inside Klott

Writing that feels like you.

Custom moods

Nine visual styles, one note.

Flip a single note between nine distinct moods (Boom, Clean, Craving, Data, Editorial, Magical, Party, Pooky and Soccer) without touching the content. Pick a vibe, ship a vibe.

Each mood swaps typography, spacing, and accents in one click — content stays put.

Be creative

Make it yours, on top of the text.

Drop a doodle layer over any klott and circle, arrow, or scribble straight onto the page. Add personality with a stamped emoji or a smiley in the margin, or use it as a shared canvas to flag areas for your collaborators: highlight a passage, arrow to a gap, and point out exactly where their input is needed. Your page, your rules.

Klippets

Reuse one snippet across every klott.

Save any slice of a note as a klippet, then drop it into as many klotts as you like. It is one reusable, linked source: edit the klippet once and every klott it lives in stays in sync. Klippets carry their own styling too, so a snippet from a Magical note keeps its sparkle wherever it lands.

Slash menu

Hit / and morph a line.

Press slash on any line and turn it into a heading, callout, code block, image, embed, equation — whatever you need next. The menu is fast, fuzzy-matched, and stays out of your way.

Public library

Browse what others published. Reuse it in one click.

A shared library of klotts people made public, from field guides to language notes to launch runbooks. Open any one and drop it straight into your own.
