FAQ
Are these AI search tools really free?▾
Every tool listed includes a real free or freemium plan you can use without payment.
What's the catch with freemium?▾
Usage limits, watermarks or premium features behind a paid plan — we call out the bucket on every card.
How often is this list updated?▾
We refresh scores and rankings whenever a listed tool ships a major change — new pricing, new model, notable feature — and re-check the whole shortlist at least monthly.
Does ToolHund take money to include tools here?▾
No. Every tool on this page is here because it earned the ranking on ToolHund Score — a blend of feature depth, pricing fit, community sentiment and shipping cadence. Vendors can't pay to appear or move up.
Can I suggest a tool that's missing from this list?▾
Yes — use the Submit link in the footer. Suggestions go through the same editorial review as our own additions, and there's no fee to be included.
