Sound familiar?

Forty exhibits, six tabs, and an answer you still can't point to.

A summary or first draft takes an afternoon when it should take minutes. You don't trust AI tools because you can't see where the answer came from, or where your documents go. Basis is one workspace for the whole matter, and every answer shows its work.

Ask

Ask your documents anything. Check the answer.

Upload PDFs, Word files, and images. Basis reads and indexes every page. Ask in plain English and get an answer that quotes the document and cites the page.

Did the tenant give written notice before withholding rent?

Yes. The tenant's notice of rent withholding is dated March 3, 2025 and cites the heating failure . Northgate's Answer alleges the system was repaired by February 19 , which the Complaint disputes .
