BlockSentient — Independent AI Software Directory

BlockSentient is an independent directory of 464 AI software tools across 22 categories. We review public vendor documentation on pricing, security, data rights, and company and product information. CTI is a 0-100 public-documentation score measuring how much relevant information each vendor publishes in those areas. We do not accept paid placements. Each scored field is based on public evidence available at the time of review.

How We Score Public Documentation

CTI is a 0-100 public-documentation score with four components: Security documentation 40 points (SOC 2, GDPR, SSO, Data Retention); Pricing documentation 25 points (Public Pricing, Free Trial); Data-rights documentation 20 points (Output Ownership, Training Opt-Out, Data Export, Data Deletion); Company and product information 15 points (Founded Year, HQ Location, Integrations). Grades: A 85+, B 70+, C 50+, D below 50. A lower CTI score means fewer scored items were documented publicly when reviewed. It is not a product-quality, security, or compliance certification.
