LetAnAgentAll scenariosSummarise long documents (contracts, reports, school letters): which AI agent to use
Researched, hands-on test pending
Our top pick: Google NotebookLM. This write-up is based on research from public sources; we haven't tested it hands-on yet and will update this page when we do. Prices were checked on 31 October 2026 and can change.
Top pick: Google NotebookLM (Gemini Notebook)
- Official site: notebooklm.google.com
- What it does: Upload PDFs and links, and it summarises and answers questions with citations back to the page.
- Rough UK price: Free; higher limits with Google AI Pro £18.99/month
- Free tier: Yes: 50 sources per notebook and 50 questions a day.
- UK caveats: Not legal advice. For a tenancy or employment contract, use it to spot questions, then ask Citizens Advice or a solicitor.
- Don't use it if you are: Confidential work documents your employer hasn't cleared.
Alternative: Claude
- Official site: claude.ai
- What it does: Handles very long documents well and is good at plain-English 'what does this actually mean for me?'
- Rough UK price: Free; Pro about £18 to £20/month
- Free tier: Yes, with limits.
- UK caveats: Same advice caveat.
- Don't use it if you are: Anyone needing answers tied to exact page citations; NotebookLM is better at that.
