Threadmark

Save and revisit important moments from your ChatGPT and Claude AI conversations.

ChatGPT is incredible at generating ideas. But long conversations make it easy to lose the ones that matter. Threadmark helps you capture, organize, and reuse important moments from your ChatGPT conversations — without breaking your flow. Instead of endlessly scrolling, re-asking questions, or copying notes into separate apps, Threadmark lets you save what’s useful, organize it clearly, and return to it instantly. How Threadmark Works • Save an entire prompt or response with a single click • Use small purple dots added directly in the chat to mark saved moments • Highlight specific text within a response to save only what matters • Organize saved threadmarks into folders for larger projects • Jump back to any saved moment instantly • One-click copy saved threadmarks from the sidebar • Branch a new ChatGPT conversation while keeping the original context • Export saved threadmarks in chronological order when needed All data is stored locally in your browser, so your conversations stay private and under your control. Why People Use Threadmark Without Threadmark: • “I know ChatGPT said something smart… somewhere.” • Endless scrolling through long threads • Copying ideas into scattered notes • Re-asking the same questions • Losing momentum on larger, multi-day projects With Threadmark: • See something useful → save it • Organize ideas into folders as projects grow • Come back days later → jump exactly there • Copy key ideas instantly • Branch new thoughts without losing context • Export everything cleanly when it’s time to ship Threadmark turns ChatGPT from a disposable conversation into a place you can actually work over time — especially when ideas evolve across multiple sessions. ⸻ Privacy-First by Design Threadmark is built with a local-only approach: • No accounts required • No external servers • No selling or sharing of data • All saved threadmarks live on your device Privacy policy: https://www.gooduse.ai/privacy ⸻ Free & Optional Upgrade Threadmark is free to use with a reasonable usage limit.
