GPTBot.io

GPTBot.io lists AI tools and bots, with a submission process notable for its guarantee rather than its scale.

The fee is $29 for a fast-track review, publication is promised within 48 hours, and the fee is refunded if the tool is rejected — a rare commitment among paid directories. Dofollow links are promised.

No DR or traffic figures are published. The refund policy meaningfully lowers the risk, which is the main argument for including it.
