The short verdict
Claude is the strongest all-round assistant we have tested for writing, contract and policy review, and analysing long documents — with a calm, precise tone that suits UK business communication.
Our Claude review
Claude, from Anthropic, has become the assistant we reach for first when accuracy and tone matter. It handles very long inputs — whole tender packs, leases, employee handbooks or a year of board minutes — and produces summaries that stay faithful to the source. Ask it to write in British English and it consistently gets spelling, date formats and register right.
For small businesses the Projects feature is the stand-out: upload your price list, brand guidelines and standard terms once, and every chat in that project uses them as context. Artifacts let it build working documents, simple web pages and data visualisations alongside the chat, and Claude Code has made it a favourite with technical teams.
On data protection, Anthropic's commercial plans (Team, Enterprise and the API) do not use your content to train models by default, and consumer users can control training use in their privacy settings. As with any assistant, review your data processing agreement before uploading personal data about customers or staff.
