What is openbidkit_yibiao?

OpenBidKit Yibiao is a desktop application built for people who write bid proposals and tender documents, a task common in construction, government contracting, and other industries that require formal competitive bidding. The tool uses artificial intelligence to help generate technical sections, produce accompanying images and diagrams, draft business sections of a bid, and manage a company's internal knowledge base of past proposals and materials. It also includes areas set aside for checking a proposal for duplicate content and for spotting items that might get a bid disqualified, along with a section for tracking bidding opportunities and announcements. The project is free and fully open source, aimed at smaller businesses that cannot afford the expensive paid bid writing services currently on the market. According to the project's own description, generating a full length proposal of around 100,000 Chinese characters can cost as little as one yuan when using a fast, cheap AI model. The software works with any AI service that follows the OpenAI style API format, and it has already been tested with GPT, DeepSeek, and Volcano Ark, plus support for running local models through Ollama or LM Studio. Under the hood this is an Electron desktop app written in TypeScript and built with React and Vite, so it installs and runs like a normal Windows or Mac program while storing your settings, cached files, and generated documents locally on your machine. It can parse documents either locally or by using an external service called MinerU for more complex files. Long running tasks like document parsing or content generation are saved as they progress, so switching between screens will not lose your work. The client also supports two different AI agent backends, called OpenCode Agent and Pi Agent, that can be switched between in settings. To use the finished program, most people just download an installer from GitHub Releases and run it. Developers who want to build the client themselves will need to run setup scripts from within the client folder and download a matching OpenCode binary for their platform first.
