What we are told
Your team needs AI. Your data cannot go to cloud AI services.
- “We were told we cannot use AI with client material.”
- “We cannot send our documents to a server we do not control.”
- “We do not want our documents improving somebody else's model.”
CLUSA is the AI your team is allowed to use.
What your team does with CLUSA.
- Read long documents. Ask a question of a 200-page contract. The answer names the page it came from.
- Summarise. Turn a board pack or a due diligence file into one page.
- Draft. Write letters, reports and clauses from your own earlier work.
- Analyse and chart. Turn a financial report into charts and tables.
- Plan. Build plans, timelines and roadmaps, and refine a strategy in discussion.
