Free tier

Answer in brief

A plan that costs nothing but limits what you can do each day, week or month.

What it means

A free tier lets you try a research tool without paying. Vendors use it to get people in the door, so the free plan often leaves out the features that matter most for work. Deep research, long reports and team sharing are common examples of features that may sit behind a paid plan. Read the plan comparison and check which research features are listed, not only the price.

Free tiers change often. A plan that gave generous limits last year may cap usage now, and the reverse can also happen. Test the free option on a question you already know the answer to. Check whether the tool shows a usage counter, and note how many reports or queries you used. That tells you how far the free plan will carry a real project before you need a paid one.
