SideThreadAI is a Chrome extension that adds side threads to ChatGPT & Gemini. Ask follow-ups without nuking context and keep chats tidy. Local-only storage (privacy-first). Free plan available; BYOK supported.

👋 Hey Product Hunt!

I built SideThreadAI, a Chrome extension that fixes a classic AI chat pain: one follow-up derails the whole convo. With SideThreadAI, you can spin off any reply into a tidy side thread; keeping the main chat clean while still exploring ideas.

What it does:

One-click side threads in ChatGPT & Gemini
Keeps context tidy so you stay in flow
Local-only storage (privacy-first) — no cloud sync

How to use it:

Free (hosted) – runs on our hosted key with a small cap so you can try it instantly
BYOK – bring your own API key for full control
Subscription – higher limits when you need more
Installs in seconds and lives right in your browser. Finally: real “threads” for AI chats.

Would love your feedback 🙏 Which mode would you try first—Free, BYOK, or Subscription?
