TL;DR: Void is the open source Cursor alternative. It offers the AI features of modern AI coding tools, while allowing you to host your own AI model locally and keep your data private. Check us out on GitHub!

About us

Hi everyone, we’re Mat and Andrew, and we’re the team behind Void. Mat’s been prompting Transformers since before GPT3 became mainstream, and Andrew did quantum computing research at JHU APL. We’re best friends who have been programming together since we were 8.

❌ The problem: the leading AI IDE is closed source

Cursor is a closed-source AI editor, which means you need to send your private data through their API every time you use it. This leads to obvious privacy concerns. It’s also expensive for developers, and it means people don’t have many choices for a great AI coding experience.

We think the future of AI should be open. You should be able to use whatever model you like and not be locked into using a private company’s API.

✅ The solution: open source

The solution: create an open-source alternative. This way, you can choose to self-host or communicate directly with any model you like, anywhere you like.

There are lots of benefits to open-sourcing besides privacy, too: on Void, you can access community-made AI features and gain full access to all your prompts.

Key features

We’re building a lot. Here are the features we’re most excited about:

• File system awareness: Void can answer questions about your entire codebase. It builds an index of all your files and uses it automatically, so you don’t manually select relevant files.
• View and edit underlying prompts: Void lets you open up the hood and view/edit every single prompt in your chat history. This is really important if you want to understand how the LLM got its answer, and it’s lacking in most closed-source tools.
• Fast edits across 1000s of lines: Even if your file is thousands of lines long, Void applies changes almost instantly. We prompt the AI to make changes the way a human would instead of rewriting the whole file.

• Full privacy / data control: All of Void’s prompt-building is done on your own computer. This means you can self-host your own model and have your data never leave your network. Or, you can connect directly to Claude, GPT, or Gemini, and not worry about sending your company data through a middle layer of communication.

We think the future of AI is open, and we’re excited about building it.
