Codebase Indexing Is Back in Kilo Code: Semantic Search Setup in One Minute

Chapters / key moments (click to jump — plays here on the page)

Codebase indexing is back in Kilo Code. Semantic search closes the gap between knowing what a piece of code does and knowing what the repo chose to call it. Setup takes about a minute — enable indexing in settings, pick an embedding provider, wait for the index to complete, and the agent can navigate a large codebase by concept rather than exact grep string.

Setup Steps

  1. Open Kilo Code settings → go to the Indexing section.
  2. Toggle indexing on for your project.
  3. Pick an embedding provider:
    • Kilo Tokens (default) — use this if you have Kilo credits; no extra key needed.
    • Mistral key (free) — bring a Mistral API key at no additional cost.
    • Ollama + LanceDB — fully local; no server to manage.
    • OpenAI, OpenRouter, or Gemini — use your existing BYOK key for any of these providers.
  4. Click save and wait for the status to read complete.

Key Takeaways

  • After indexing, the agent picks up a semantic search tool — instead of running repeated greps guessing at terms, it describes the concept it's after and gets the right files and line ranges in one call.
  • Solves the "I know what this code does but not what the repo calls it" problem common in large unfamiliar codebases.
  • Embedding providers are all BYOK — zero markup, same as all other model calls in Kilo Code.
  • The Ollama + LanceDB option keeps the entire index local — useful for proprietary codebases that should not be sent to an external API.
  • The index rebuilds automatically as the codebase changes.
