Syntheia brings two things lawyers do every day into ChatGPT.
Compare: upload a counterparty's draft and your last version, and Syntheia returns a clause-by-clause list of insertions, deletions, and moved text, with a redlined document to download.
Query: ask a question about one agreement, a group of agreements, or your whole workspace. Syntheia navigates each document's structure, follows cross-references, and returns the exact provision text with a link to the source clause, so every answer is grounded in the document rather than in a summary.
Documents stay in your private Syntheia workspace, and results are scoped to your account.

- redline-issues-list
Turn a Word document's tracked changes (redline, markup, blackline) into a structured issues list for lawyers. Use this whenever someone uploads or refers to a redlined .docx and wants the changes reviewed, summarised, risk-assessed, or turned into an issues list or change log -- including casual phrasings like 'review this redline', 'what did they change', 'go through the counterparty's markup', 'summarise the blackline', or 'is there anything nasty in here'. Reads w:ins/w:del revisions straight from the OOXML in document order with real clause numbers, separates out formatting-only edits, picks up Word comments and counter-edits, and builds a change / comments / impact table -- then asks which side of the deal the user is on and re-weights the impact ratings from that position.
