Editorial Policy

CoAI aims to give everyone searching for AI tools access to trustworthy information.

Verification

• Listings are based on each service's official website and documentation.
• Factual data (pricing, API availability, commercial-use terms) records its source and verification date.
• Unverified information is explicitly labeled "unknown" — we do not state guesses as facts.

Rankings

• Rankings follow our editorial criteria (capability, usability, Japanese support, pricing).
• Sponsorship never affects organic ranking positions.

Sponsorship & advertising

• Sponsored listings are clearly labeled "Sponsored" and separated from organic results.

Affiliate links

• Some links are affiliate links. We may earn a commission, but this never influences content or ratings.

Reviews

• User reviews are moderated before publication; false or spam reviews are rejected.
