The record

Product: Endrel brings API documentation into a searchable workspace and uses AI review to flag documentation drift.
Imports and sync: It imports OpenAPI, Swagger, and Postman collections and rechecks specifications when they change.
AI review: The reviewer flags schema drift, missing endpoints, inconsistent conventions, breaking changes, and missing examples.
Team collaboration: Front-end, back-end, and QA teams can comment on endpoints, flag mismatches, and resolve them inline.
Access: Endrel describes granular permissions at workspace and service levels, with options for public references or restricted internal APIs.
REST API: The product describes itself as developer-native and says it provides a REST API.
Integrations: The maker lists OpenAPI, Swagger, and Postman as supported import formats; no other integrations are stated on the pages reviewed.
Security: The privacy policy says safeguards include encryption in transit and access controls, and notes it cannot guarantee absolute security.
AI data handling: Endrel says it has not published a blanket no-training commitment or final model-provider policy and advises against importing secrets or production credentials during Founding Access.
Support: The privacy policy lists [email protected] for questions, requests, and support inquiries.
Availability and limits: Founding Access is open to the first 10 teams for free; the maker says long-term pricing and lifetime-free access have not been promised.
Audience: Endrel identifies front-end developers, back-end engineers, QA engineers, and tech leads on product teams shipping APIs as its intended users.
Founder: Endrel says it is founder-led by Nil Patel.
Price from: ₹1,499/mo
