What Sets Us Apart
The self-hosted version is completely free (only pays for API), but requires technical knowledge; the hosted version is US$10/month, saving time and effort, but may not be cost-effective for small companies.
Japanese-style AI search, excellent localization for Traditional Chinese, and generous free quota
FreeThe free version has unlimited basic search, and approximately 5 Pro searches per day (200 points per day, resets at midnight), as well as a daily quota of 3 file analyses (confirmed on the official website on 2026-07-30); the paid Pro plan, after using up 15,000 points per period, can still enjoy up to 300 Pro searches per day (confirmed on 2026-07-26: the latest blog post on the official website states 300 times, while the FAQ page states 100 times, which is outdated and not updated).
MIT open-source license, allowing commercial use of self-hosted versions. New users have a US$1 initial quota for testing. The pay-as-you-go model can easily exceed the budget during high-frequency queries, so it's recommended to test the cost with the initial quota before large-scale use.
