Worth knowing
ChatHub
- The size of the free usage quota in the web app is not published; more usage and the premium features need a paid plan.
- Pro limits advanced models to 1,500 queries a month and document uploads to 300. Only Unlimited removes those caps.
- Custom chatbots for your own OpenAI-compatible endpoints are available only in the browser extension.
- Refunds are offered within 7 days of purchase, prorated by days used, and not for renewals.
Merlin
- Merlin's website answers automated readers with a security check, so its pricing page could not be read and paid plan prices are unverified.
- Store listings do not give a clear lineup: the US App Store lists Merlin Pro at $20.00 and Merlin Unlimited at $15.00 a month, and Google Play shows items from $3.49 to $499.99.
- The free plan is capped at up to 102 queries per day, and voice chat, premium tools and team collaboration are described as premium features.
- The US App Store also sells query top-ups that expire, such as 3,000 queries valid for 30 days at $4.99.
