Share this chain

Anyone with the link gets a read-only, live view that follows your edits: they can open every thought and see verdicts, but not change anything. Copy the link, or post it directly. Revoke it whenever you like.

Share to
Page options Plus

Shape the link for its audience: a readable address, a line of context for people who land on it cold, a password, an end date, or a page without our sign-up bar.

Custom link, description, password, expiry and no sign-up prompt.

Shared chains

Read-only links you’ve created. Anyone with a link sees that chain live. Revoke to cut access.

That's the cap, for now

Reference in another map Plus

A reference is a live, read-only copy: the other map shows this thought's title and verdict, and when the verdict changes here, any conclusion built on it there is flagged. Editing stays in this map. Use it when a belief you settled once becomes evidence somewhere else.

Templates

A template is a map's skeleton: the questions, hypotheses and conclusions you tend to need, already laid out and linked, with guidance in each node. Use one to start a new map in seconds. Save the current map as a template to reuse your own structure; verdicts, confidence and labels are reset so the new map starts un-judged.

Snapshots

A snapshot freezes this map exactly as it is now. Keep working, then come back and ask what changed: which verdicts moved, what was added or removed, which links you drew. Take one before a decision, a pilot, or a meeting, so you can see later how your thinking moved.

Fragility report

Every conclusion rests on hypotheses, often several links away. This report follows the links down and shows two things: which hypotheses carry the most conclusions, and which conclusions would break, because they stand on a falsified hypothesis, an untested one, or nothing at all. The count measures influence, not doubt: a hypothesis with many conclusions on it is the one worth checking, not the one most likely to be wrong. Click any row to jump to it.
