SideThreadAI

I built this after running into the same problem: AI chats get messy fast. Exploring tangents usually means losing context or duplicating half the conversation. OpenAI recently added a "branching" feature, but it still feels more like cloning chats than keeping them organized. I wanted something closer to Slack-style threads. So I made SideThreadAI, a Chrome extension that adds threads to ChatGPT and Gemini: - Start a side thread from any message. - Keep the main chat clean while exploring tangents. - Works directly in both ChatGPT and Gemini. You can check it out here:…

SideThreadAI launched on September 28, 2025 with 8 votes, #1,468 of 8,160 launches that month and more than 50% of that year's launches. The site was still online in September 2026, 1 year on.

What it does

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.

Boost ChatGPT productivity with side threads. Open follow-ups in parallel, keep context clean, and manage threads locally. Also works with Gemini.

    I kept losing ideas in long chats, so I built a tiny Chrome extension to make navigating between turns/prompts way easier. Idk why this isn't a native feature on all LLMs. Anyway, free and open source on GitHub or the Chrome Store. Hope it's helpful!

  • I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

    Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
