Show HN: Vexp – Your AI coding agent forgets everything. Mine doesn't (vexp.dev)

Vexp, a new AI coding agent, aims to enhance coding efficiency by building a local dependency graph of your codebase, operating entirely on your machine without requiring cloud storage or external account sign-ups. This innovation allows Vexp to intelligently filter relevant code snippets during a coding session, significantly reducing token usage by up to 74%—an essential shift that eliminates the noise typically generated by conventional AI agents that scan and misinterpret entire codebases. By utilizing tree-sitter for code parsing and hybrid search methods, Vexp can auto-detect user intent and deliver precise, context-relevant code while maintaining user privacy. Significantly impacting the AI and ML community, Vexp addresses common limitations of cloud-based context engines that require data uploads, which pose privacy risks. With its ability to build cross-repo dependency graphs and analyze code changes using advanced structural diff computations, Vexp stands out in the market, providing full source access to function signatures and maintaining a lightweight token budget during usage. Priced affordably at under $20 per month for professional developers, Vexp integrates seamlessly into existing workflows through a VS Code extension, offering a powerful tool for enhancing developer productivity while ensuring data security.
