Your idea store for ChatGPT.
Mark key moments in ChatGPT conversations and turn them into better prompts. Say goodbye to scrollback.
Great ideas get buried in scrollback
You're deep in a conversation with ChatGPT. It surfaces something brilliant—an insight, a code pattern, a solution you didn't expect.
Then the conversation keeps going. The insight scrolls away. Later, you remember it existed but can't find it. The context is gone and you forgot the keywords needed to search for it. Then you lose time to scrollback.
ChatMarkerAI lets you mark what matters, when it matters, so nothing valuable gets lost. Without leaving the conversation.
How it works
Three steps to transform your ChatGPT workflow.
Select Text
Highlight any text in a ChatGPT response. A marker button appears instantly, ready to capture your intent.
Choose Your Intent
Choose a marker type based on your intent—ask a question, explore deeper, flag an error, or preserve what works.
Build Your Prompt
Select markers, add information, and generate contextual follow-up prompts with one click. Your markers auto-group by intent for clarity. When you're ready, one click sends the prompt to ChatGPT.
Your markers are saved and can be used later.
Intent-based markers
Each marker captures your intent. Ask a question, flag an error, preserve what's working. Your markers shape the prompts you generate. You can also add information to the prompt at any stage.
