Turn an unfamiliar repository into a software engineering model.

Upload student software or research code. RepoLens reconstructs the core functionality, architecture, UML-style diagrams, execution flows and implementation evidence without relying on prior chat memory.

Upload repository ZIPSource files are filtered server-side; 50 MB max in V1.

Public GitHub repositoryClone a public repository directly.

Analysis model

Choose the engine for the same evidence-grounded repository audit.

AI providerModel nameModel timeout per attempt (minutes)Free models default to 15 minutes. An automatic report retry gets a fresh attempt limit; all model requests together are capped at 30 minutes. You can cancel at any time.API key (required)

Use the complete secret key from OpenRouter API keys, usually starting with sk-or-v1-. An OpenAI key or masked key preview will not work. openrouter/free still requires a valid key.

No repository is sent and no model generation is requested. The key stays only in this form’s memory until analysis or refresh.

Keys are sent to your chosen provider through the RepoLens server, cleared from this form on submission, and never saved in storage, logs or exports.
