Turn AI-generated code changes into plain English for faster review

Problem

Engineers spend a lot of time reviewing AI-generated code diffs to understand intent and risk. One developer explicitly asked for an AI tool that can 'look at a diff and present it to me' in a more understandable way, rather than just writing code.

Solution

Upload or link a diff (PR, commit, local changes) and get a structured explanation: purpose of change, impact scope, potential risks, suggested test points, displayed per file/function; optional inline annotations help understanding without modifying code.

Users

Engineers, tech leads, and code reviewers using AI coding assistants

MVP

Support pasting diff text or GitHub PR link; call LLM to generate chunked explanations and risk summary; output a shareable read-only report page; provide a local CLI for one-click generation.

Revenue

Free tier limited to 20 runs/month; Pro subscription $9/month unlimited with private repo support; team plan per seat with custom review checklists.

Why now

AI coding has exploded, making review the new bottleneck; big vendors don't focus on diff explanation, and an indie developer can validate quickly.
