Pre-release
Lithic is an outliner for people who plan their own work. Write your thinking as a list, drag a line onto a day, give it an hour — and it stays where you put it, on every device and beside everyone else who is in there with you. Hosted in Germany.
One email when we open. No newsletter.
The problem
The list is where the work gets thought through; the calendar is where it gets a time. Between them sits a copy — you retype a line into an appointment, and from that moment there are two of them, and the second one is wrong by Wednesday. Lithic keeps one row. Plan it, move it, finish it: it is the line you wrote, whichever of the two you are looking at.
What it does
Outline
New row, indent, fold, zoom into a branch, move it somewhere else — all from the keyboard, without reaching for the mouse. Long outlines stay quick to scroll, so the list you keep everything in is still the list you actually open.
Planner
Drag a row onto a day. Give it a start and a length, or leave it untimed and just say "today". When the week starts, which days count as working days and how early the grid opens are settings, not opinions we hold for you.
Moving things
Drag a row and everything under it follows. If somebody is writing inside that branch while you move it, their words are still there afterwards: moving a row changes where it sits, never what it says.
Together
Live editing with everyone visible where they are working, on every device you are signed in on. Your outlines are kept on the device as well as on the server, so a lost connection is a pause rather than a stop.
History
A version is kept when something changed — not every time a cursor moved. That is the difference between a history you can restore from and a list of ten thousand identical entries nobody has ever opened.
Markdown
Every outline reads and writes as Markdown: a nested task list, with the plan written into the line. Take it out whenever you want, edit it elsewhere, put it back. Nothing stays behind and nothing needs converting.
Compare
Most people run one of each and copy between them. The two middle columns are categories rather than named products — feature lists move faster than a table can keep up, and the point here is the shape of the tool, not whose logo is on it. Lithic is pre-release, so read its column as a commitment rather than a shipped feature list.
| An outliner | A calendar app | Lithic | |
|---|---|---|---|
| Write your thinking as a list | that is the whole point | not really | that is the whole point |
| Give a line a day and an hour | a due date at best | yes, by hand | by dragging, in day, week or month |
| One item rather than a copy | the plan lives elsewhere | the thinking lives elsewhere | the same row, in both places |
| Everyone in the same document | sometimes | invitations, not editing | live, everyone visible |
| Move a branch without losing edits | depends on how it syncs | not applicable | moving changes where, never what |
| Take everything with you | usually files | an appointment export | Markdown, out and back in |
| Data in Germany | depends on the vendor | depends on the vendor | data centre in Germany |
Categories rather than products, on purpose: a table naming vendors is out of date the week after it is written, and we would rather be accurate than pointed. Written July 2026.
Markdown
An outline is stored the way you would write it out by hand: a nested task list, with the plan written into the line itself. That is not an export format sitting next to the real one — it is the document. Read it with anything that reads Markdown, write it back, and the plan comes back with it.

Data protection
What you plan says a good deal about what you do all day, and it belongs in a German data centre rather than in a US cloud wearing a European label. The data processing agreement belongs to the plan, not to the invoice.
Early access
The outliner and the planner run; we are finishing the parts you would notice were missing. Leave your address and we will write once — when you can sign up, not before.
