Programmers and software developers lost the plot on naming their tools

It’s free, open-source software that should run anywhere, and you can read more about it here.

From text to token: How tokenization pipelines work
By James Blackwood-Sewell on October 10, 2025 When you type a sentence into a search box, it’s easy to imagine the search engine seeing the same thing you do. In reality, search engines (or search databases) don’t store blobs of text, and they don’t store sentences. They don’t even store words in the way we […]
