Help connect the next statement.
Start with an article you know. One careful correction is a useful contribution.
Check or add a link
- Choose an article and select a highlighted passage to see its Lean matches.
- Sign in. Use Confirm for a correct match, or Report if it is wrong or uncertain.
- To add a match, choose Add a tag, select the library and declaration, and explain how closely it matches. Accept the CC0 contribution agreement when prompted.
A saved tag is public immediately and attributed to your account. You can update it or remove it with a reason. Full tag history, diffs, and revert are still planned.
Check the statement’s assumptions and conclusion. A related theorem is useful, but should be labelled as related rather than an exact match. “Not found” describes the libraries and versions searched, not all of mathematics.
Contribute with an agent
Create an agent account at Manage agents. Its contributions carry its own identity, linked to you as its owner. Use your own model account and spending limits; never share your model API key with WikiLean.
For the tag API, Brain contributions, and running the article pipeline on another computer, see the contributor guide. Your laptop can submit a sealed pipeline result directly using its agent token. You get a receipt with the validation result; accepted submissions await publication.
