Stewie Reflect
Stewie Reflect is an automated tool that analyzes a pinned snapshot of a GitHub repository and generates a source-grounded 'owner's manual.' This manual documents the actual product behavior implemented in the code, not just the architecture or intended design. Each claim is linked to the specific files and functions that support it, providing verifiable evidence. The manual also highlights attention areas — parts of the codebase that require owner decisions — and explicitly identifies unknowns where the repository does not provide enough information. Stewie Reflect focuses on reducing 'comprehension debt,' the gap between what the code does and what the team believes it does. It is particularly useful when returning to a codebase after time, onboarding new team members, or preparing for major changes. The tool performs a quality check before delivering the manual; if the generated content does not meet the bar, it is not delivered. Generation is asynchronous and free for a preview that includes one complete chapter and all findings. Users can then unlock the full manual and a Markdown export for a one-time payment of $19 per snapshot. The service operates with read-only GitHub access, ensuring no modifications to the repository. It pins the manual to a specific commit, so the documentation is tied to an exact version. This makes it useful for audits, knowledge transfer, and understanding legacy code.

Problem solved
Developers and product managers often struggle to understand the exact behavior of their existing codebase, especially when making changes to billing, authentication, or usage limits. This leads to risky decisions based on assumptions. Stewie Reflect addresses this by creating an evidence-based manual that documents what the code actually implements, highlighting uncertainties and attention areas.
Use cases
- Onboarding new team members to understand product behavior
- Preparing for a major feature refactor or migration
- Auditing payment and authentication logic before a release
- Creating a snapshot document for compliance or knowledge transfer
- Identifying undocumented edge cases and assumptions in the code
- Reducing reliance on tribal knowledge for critical systems
- Understanding the impact of plan downgrades on user data
Audience
- Developers
- Product Managers
- Startups
- Enterprise
