We are committed to harnessing the powerful capabilities of large language models to develop a next-generation project code assistance tool tailored for professional developers and teams. Unlike other code generation products on the market, which are limited to partial function completion within single files, our project can automatically generate cross-file project plans based on a user’s one-sentence description. With the user’s approval, it proceeds to incrementally generate code across files. It also uses a conversational approach to fine-tune the generated code under the guidance of expert users and runs automated tests to ensure code usability and reliability.
