Sider

Sider's killer feature is group chat: send one prompt to multiple AI models at the same time and compare their responses side-by-side. This is genuinely useful for tasks where model quality varies — creative writing, code generation, nuanced analysis. Instead of guessing which model handles your prompt best, you see all the answers at once.

AI power users who already know the difference between models and want to pick the best answer for each task. Developers comparing code solutions, writers testing different creative approaches, analysts who want multiple perspectives before committing to an answer.
