What Encypher does: Free tools from the Co-Chair of the C2PA Text Provenance Task Force. Sign and verify C2PA-compliant content authentication. Full API and SDKs in Python, TypeScript, Go, and Rust available.
Who it's for: Developers building content authentication, publishers exploring provenance technology, and researchers testing C2PA text standard implementations.
Key differentiator: Built on the C2PA text standard (c2pa.org) we co-authored with NYT, BBC, AP, Google, OpenAI, Adobe, Microsoft and others. Same technology powering our production API.
Primary value: Test cryptographic watermarking without signup. Standard publishes January 8, 2026. Sign up at encypherai.com for API access and documentation (API base URL: api.encypherai.com).
