How to choose ai assistants software

Start with the work: a sourced research brief, a spreadsheet question or a reusable document. A consumer assistant, a managed workplace subscription and a developer API can have different commercial terms. Compare the actual account and tools your team would keep.

Questions to ask before you buy

Put your shortlist to the test

Prepare an original brief with a known answer, a small non-confidential file and a current research question. Check factual accuracy, usable citations, revisions and export. Record the date, account, plan and tools used. Test business permissions and connected-data boundaries separately from output quality.
