Set up and configure DiffGuardian
Understand what will be built, what is being built, what others built and any part of your repository, fast. Use your voice, and choose the right model for each job.
Guides
- Understand an agent's plan quicklyOpen the Plans tab to get a summary, diagrams and a conversation about the plan your coding agent wrote, instead of reading it all.
- Watch an agent work, and ask about itFollow each coding agent in its worktree as it codes, see what its changes touch as the graph grows, and ask about it by voice.
- Understand a pull request quicklyThree ways into a pull request: read it with Trace It, hear it by voice, or see what it touches in the blast radius graph.
- Understand your codebase quicklyAsk your whole repository a question out loud or in text, and follow the answer on a graph that builds as it is explained. Pro.
- VoiceTalk to a pull request or your codebase and hear the answer. Choose OpenAI, ElevenLabs or your system voice, a language and a voice. Pro.
- Choosing modelsPick a local model or your own cloud key, then assign a model to each feature: Trace It, chat, voice answers, Learn Me and general tasks.
- TroubleshootingFixes for sign-in handoffs, locked Pro features, undetected local models, refused cloud models and dictation.
Use it alongside your PR tools
Automated tools flag what they find. DiffGuardian helps you understand, fast, by voice, in conversation and on diagrams: what an agent will build (its plan), what it is building (its worktree), what others built (their pull request) and any part of your repository. It builds a code knowledge graph and a file index of your whole repository on your machine, so its answers are grounded in your real code. Install both.
| Tool | What it does | What DiffGuardian adds |

| GitHub Copilot code review | Posts an automated review, with suggested fixes, on your GitHub pull request. | Helps YOU understand the code by seeing the architecture, fast. |
| Greptile | Indexes your repository and runs review agents against your pull requests. | Helps YOU understand what agents will build, fast. |
Voice and codebase questions are Pro. Each page sets out where your code goes, which git hosts the tool supports and what it costs, from the vendor's own public documentation.
