Hackerman.AI

Hackerman's first product is Koi, a native code editor for macOS built around immediate interaction, large files, local AI, and programmable workflows. Koi is designed to be fast enough to disappear, works without an account, and can be extended in ordinary Python. The company also built Keypress.sh to measure keypress-to-paint latency, publish reproducible benchmarks with raw datasets and methodology, and investigate topics such as editor responsiveness, large-file editing, syntax highlighting, rendering pipelines, and programming language implementation.

Koi is suitable for developers who prioritize performance and privacy, and who want a code editor that remains responsive even with large files and growing codebases. It is designed for those who prefer local-first tools and want to avoid dependence on cloud services, accounts, and telemetry. With local AI support, Koi can be used by developers who want AI assistance that works with their own files and models, keeping data and workflows under their control. The editor's extensibility in Python makes it appealing for developers who want to customize their workflow.

The page does not provide specific pricing information for Koi or other Hackerman tools. It emphasizes that Koi works without an account, suggesting a possible free or local-first model, but no details are given.
