Keyboard-driven
Modal and vim-flavored: a NORMAL mode to navigate and command, an EDIT mode where the title is live. Capture a thought without reaching for the mouse.
one tree, infinitely nested
Outline at the speed of typing.
listlis is a keyboard-first outliner. Every thought is a node with a title and an optional Markdown body, nested as deep as the idea goes. No dragging, no chrome — the text is the interface.
Press o to add a line. Press Tab to nest it. That is the whole loop.

• Fractional-index reordering
Order is a string between its neighbors, so a
move is one row — never a renumber. ▸ Inbox email-in

One tree
Tasks, notes, and ideas share one structure instead of scattering across apps.
No drag
Reorder and reparent from the home row. Fractional indices keep moves cheap.
Yours to keep
Copy any subtree out as clean Markdown — titles become headings, notes come along.
What it does
A small set of sharp tools, not a suite.
Tabm
Infinite nesting
The whole app is one tree. Indent, outdent, and reparent any subtree. Order is a fractional index between neighbors, so a move writes one row, never a renumber.
⇧↵
Markdown bodies
Every node has a title and an optional Markdown body. Keep the outline scannable; open a note when a line needs room to breathe.
!c
Styles and types
Turn any node into a todo and toggle it done — completion carries the whole subtree and rolls up to the root. Style nodes to mark what matters.
t
Themes
Light and dark, several palettes — a planetarium console, a cream notebook page, embers in a stove. One key flips light to dark and remembers each side.
S
Sharing
Publish a node as a read-only link, co-edit a subtree live, or let a node receive mail. Sharing a node shares its descendants — the boundary is the subtree.
Inbound
Send things to your tree from anywhere.
Give a node an address and it becomes an inbox. Forward an email or POST a webhook, and the message lands as a child node — captured from your phone, a script, or a service, without opening the app.
Email a node
<token>@lists.listlis.com
Or POST a webhook
POST /in/<token>
Tokens are per-node, rotatable, and revocable. Attachments ride along.
