Hi HN,

I built NeuralSide — a minimal AI sidebar for Chrome. It brings GPT-5 and Mistral into the browser sidebar so you can ask questions, write, and code without switching tabs.

Why I made it: - I was tired of context switching between a page and a separate AI tab. - I wanted quick Q&A, writing help, and code explanations in the same window.

What it does: - GPT-5 & Mistral in one sidebar - Chat, writing, code help, summarize/explain text from the page - Keyboard shortcut + lightweight UI - No page takeovers, no distractions

I’d love feedback on: - UX (is the sidebar smooth enough?) - Prompts/presets you want - What to add next (multilingual packs? export? site-specific presets?)
