DeepL
Fact sourceWhen to pick it Choose DeepL when whole documents need translating and glossaries plus shared style rules must stay consistent across files: the Team tier gives 1,000,000 characters per user per month and 5 shared glossaries, and only Business reaches unlimited characters.
When to skip it The page defaults to Germany (EUR €) and the figures are billed-annually prices, so another region or the Monthly view differs; the trial runs 30 days, and translation memory starts at Business. To self-host a translation model instead of paying per character, the closer directory record is Ollama; to keep translation in a browser sidebar alongside other models, the closer record is Monica. This is not a ranked review.
Verified price: Individual 7.49; Team 24.99 / user; Business 49.99 / user — EUR / month (billed annually); Write Pro add-on 6.99 EUR / user / month (billed annually, tax included); annual billing saves 16% (region: Germany (EUR €), checked 2026-10-12). Annual prices are not converted to monthly.
Official sourceNotebookLM
The official site and help centre now write NotebookLM as Gemini Notebook: the sign-in page at notebooklm.google.com is titled Sign in to Gemini Notebook.
Fact sourceWhen to pick it Choose Gemini Notebook (formerly NotebookLM) to turn a pile of your own files into a research workspace with explicit source caps: the free Standard tier gives 100 notebooks per user and 50 sources per notebook, and Pro raises that to 500 and 300.
When to skip it It answers only from what you upload and adds no outside facts; source caps are fixed per tier — 100 on Plus, 300 on Pro, and 500 or 600 on Ultra — and going over means another notebook. For open-web retrieval with clickable citations, the closer directory record is You.com; to run the same PDFs through local or self-hosted models without buying Google AI, the closer record is Ollama. This is not a ranked review.
