Transform any AI Evidence/Workflow into a self-contained, verifiable evidence package.
Get started in seconds. Install the epi-recorder package from PyPI with a single command.
$ pip install epi-recorderTransparent "Flight Recorder" for your AI. Wrap your script to capture inputs, LLM calls, and outputs into a single sealed file.
$ epi record script.pyThe EPI Verifier replays the file in a sandbox. It proves the output was generated by the exact code and inputs claimed.
$ epi verify scan_01.epiSend the .epi file to auditors, investors, or regulators. It's a portable
proof of work that doesn't need your secrets.
(Drag & Drop File Here)Self-contained HTML viewer. Open .epi files like PDFs. No execution, no risk. Human-readable timeline of events.

Self-contained .epi files. Store evidence + viewer in one portable archive.
Same crypto as Signal & SSH. Tamper-proof, military-grade security.
SHA-256 hashing ensures file integrity. Deduplication by design.
OpenAI, Anthropic, Ollama, Google Gemini. Automatic capture.
Cached LLM responses enable deterministic re-runs without API calls.
