Local vs cloudWhy these exist
Varven runs a language model on your own computer, so questions like “what does this filename mean” and “will this actually run when I want it to” come up before you’ve typed a single prompt. Every tool here answers one of those questions directly.
They are free, they need no account, and they run entirely in your browser — nothing you enter is transmitted anywhere.
