## What the story says

Propel builds AI agents that review pull requests. It indexes customer repositories in Chroma Cloud so the agent can retrieve context across the whole codebase and its dependencies, combining semantic search with regex and AST-based analysis.

Summary written by usedby from the source page, in English. The figures are those of Chroma and Propel, not ours.

> Customer repositories are continuously indexed in Chroma Cloud, enabling the agent to retrieve relevant context across the entire codebase, even when related logic is far from the files under review.

> Chroma is the obvious choice for Propel, enabling our agents to reason across entire repositories and dependencies. The result is more accurate reviews and a higher standard of feedback.
