How to read the comparison table. 'Best for' is the honest one-line answer to who should buy this ai search AI tools tool — not a feature list. If that line does not describe you, skip the tool regardless of price. Free plan column reflects what you can ship, not trial length. A 7-day trial is not a free plan and we mark it accordingly.
Use the table to shortlist two ai search AI tools tools, trial both on real work this week, and check Best AI Utility before committing — rankings reveal which tools hold up.
