Introducing Jolt: AI Codegen and Chat for 100K to Multi-Million Line Codebases

The Jolt public beta is live today, and sign-ups are now open for the first time.

We built Jolt to solve a fundamental problem with AI coding tools - they struggle with larger, real-world codebases and often fail to accurately determine the context files for your prompt. Manually selecting context files is a non-starter when you're working on larger codebases or unfamiliar code. It's a broken product experience.

Most AI coding tools rely on some flavor of vector-embedding RAG to determine the files related to your prompt. The reality is that vector-embedding search is not effective on code, and there is a sharp drop in efficacy as codebase size increases. We developed a novel way for Jolt to understand large codebases and automatically determine context files. Our approach scales to multi-million line codebases - the largest codebase using us in production is over 8M lines.

Jolt is designed specifically for large, production codebases. It features codegen and code chat on both the web and in any VSCode-based IDE. If you've ever been frustrated by AI tools that stumble when your project tops 100K lines, Jolt is here to help.

Developers and engineering teams are already using Jolt to write and refactor code, add tests, fix bugs, generate documentation, and onboard developers quickly. We'd love for you to give it a try and share your feedback. Visit here to sign up and start using Jolt today.
