FAQ
- NotebookLM (skimming bid and proposal documents): Upload the notice and statement of work in full and ask, 'Pull out only the evaluation scoring and the required documents.' Check first for the items that would disqualify you if missed.
- Mapify (skimming long reports first): Feed in an industry report or white paper to see its structure, then decide which chapters to read. In minutes, you can judge whether it is worth reading in full.
- Claude: Create an account and you can use it free up to a daily limit. If you use it heavily for work, you’ll hit the free limit quickly.
- NotebookLM: Works right away with just a Google account. There are limits on the number of notebooks and sources, and a paid plan raises them.
- Mapify: The free plan lets you try basic conversion. It has volume and feature limits, so a paid plan makes more sense if you process documents regularly.
