What it is

Sensei AI is an AI coach for combat sports, covering Muay Thai, BJJ, boxing, wrestling, judo, sambo, and MMA. Users record a training clip on their phone, upload it, and receive movement analysis, two correction tips, and matching drills, then film again to verify improvement. It is clearly positioned as a supplement to an in-person coach: it handles between-class video review, training history, and Fight IQ tracking, rather than reading live sparring pressure in real time.

Core capabilities

The product is built around four main components: The Map, chat coach, video analysis, and Fight IQ. The Map is a manually curated combat-sports technique graph with 1,000 techniques, 145 positions, and 321 transitions. Video analysis uses an in-house BlazePose Heavy pipeline, extracting 33 key points, 14 joint angles, and 3 axes of rotation. Notably, Sensei emphasizes “say uncertain when uncertain”: when the footage is incomplete, it asks users to reshoot instead of inventing precise numbers. Its output feels coach-like: it points to specific frames, gives two cues, and guides the user back to the mat to practice.

Pricing and privacy

The free plan requires no credit card and includes 5 video uploads per month of up to 30 seconds each, 30 chat messages, and full access to the Map. Pro costs €9.99/month or €79.99/year, with a 7-day trial after checkout. It includes unlimited uploads, videos up to 120 seconds, Fight IQ historical trends, periodized reports, opponent scouting, and drill verification. Privacy disclosures are fairly detailed: EU-only hosting, Cloud Run Ireland and Supabase EU, automatic video deletion after 90 days, face blurring for sparring partners before analysis, and no use of third-party motion-capture APIs.

Pros, cons, and who it’s for

Its strengths are strong vertical focus, ruleset awareness, specific feedback, and restraint when confidence is low. The free allowance is also enough to try the product properly. Its limitations are that it does not offer real-time moving-camera analysis, cannot replace an in-person coach, and does not provide public accuracy benchmarks, Chinese-language support, or information about an open API. It is best suited to combat-sports enthusiasts, beginner-to-intermediate athletes, and coaching-assistant scenarios where users train regularly and are willing to record videos for review. Advanced athletes can also use it as a logging and verification tool, but should expect the model to be more conservative.

Access from China

The source text does not provide information on availability from mainland China, payment methods, or localization, so this remains unknown. If access or payment is restricted, alternatives include in-person coaches, YouTube or domestic video tutorials, general-purpose AI assistants combined with human review, or local sports video analysis tools.
