Greptile: Your AI Solution for Navigating Large Codebases

Greptile is an innovative AI-powered API designed to search and understand large codebases in natural language, making it easier for software teams to build powerful internal development tools. Founded in 2023 by Daksh Gupta, Soohoon Choi, and Vaishant Kameswaran, Greptile operates out of San Francisco with a team of three, under the guidance of group partner Brad Flora.

The core idea behind Greptile is to leverage AI to simplify the complexities associated with large codebases, which are often challenging to navigate, especially as software companies grow and their codebases become more complex. Greptile is used by developers at over 300 companies, including industry giants like Stripe and Amazon, to facilitate LLM-powered codebase Q&A, automatic documentation updates, PR review automation, and more. It can be deployed via the cloud or hosted 100% on AWS in an air-gapped VPC.

Who Are the Founders of Greptile?

Greptile's founding team consists of three dynamic individuals:

Daksh Gupta - Co-founder of Greptile, the AI expert with comprehensive knowledge of any codebase. Daksh studied Computer Science at Georgia Tech and interned at Amazon, where he was recognized for his exceptional performance by having an Amazon locker named after him.

Soohoon Choi - Founder of Greptile. Soohoon brings his expertise and vision to the team, driving the development and application of Greptile's innovative solutions.

Vaishant Kameswaran - Founder of Greptile with a background in Computer Science from Georgia Tech and a minor in Linguistics. Vaishant's diverse skill set contributes to the linguistic and technical aspects of Greptile's AI capabilities.

What Problem Does Greptile Solve?

As software companies expand, they encounter several issues related to their codebases:

Increased Complexity: Codebases grow more intricate over time.
Accumulated Legacy Code and Tech Debt: Older code and technical debt become burdensome.
Outdated Documentation: Keeping documentation current is a persistent challenge.
Staff Turnover: Original engineers may leave, and new engineers often struggle with unfamiliar code.

To address these challenges, developers typically:

Brute Force Understanding: This method is labor-intensive and time-consuming.
Seek Subject Matter Experts: This is often impractical if experts are unavailable or too busy.
Use Inadequate Tools: Tools like GitHub Copilot lack the capability to provide full code context, leading to suboptimal results.

Greptile offers a solution by indexing and searching large codebases, allowing LLMs to find the right context and enabling developers to build AI-powered internal tools.
