A ChatGPT Prompt Manager for Developers: Save Prompts, Bookmark Replies, Search Threads (Chrome Extension)

#chatgpt #productivity #webdev #chrome

If you use ChatGPT for real work, you’ve felt this:

You wrote a great prompt once… then lost it.
You remember “that one answer” from a long thread… then waste 10 minutes scrolling.
Your best snippets end up scattered across notes, screenshots, and half-saved chats.

That’s not a motivation problem. It’s a retrieval problem.

I built Chat Navigator — a Chrome extension that adds a sidebar inside ChatGPT for:

Search
Message bookmarks
Prompt management (a prompt library you can reuse)

Install (Chrome Web Store): https://chromewebstore.google.com/detail/aapchhfjoohmohpdcadghjacklcdfdml?utm_source=dev

What it does

1) Search long threads without scrolling

Chat Navigator gives you a sidebar outline + search so you can jump to the message you need instead of dragging a scrollbar through a 200-message conversation.

2) Bookmark messages, not just chats

Most of the value is in a single reply: a code block, a checklist, a debugging plan, a rewrite.

Chat Navigator lets you bookmark the exact message so you can retrieve it later.

3) Prompt management: build a real prompt library

If you keep rewriting the same prompts (“review my code”, “summarize this”, “draft a reply”, “generate test cases”), you’re wasting time.

Save your best prompts and insert them when you need them.

4) Code extraction

If you’re a dev, you know the pain: great snippet buried in a thread.
Chat Navigator pulls code blocks out so you can copy cleanly.

The workflow (this is the part that actually changes your day)

Here’s the simple system I use:

1) When a reply is worth reusing (snippet, checklist, explanation), bookmark the message.
2) Give it a label you’ll actually search later

Examples: rails caching p95, sidekiq retries, sql index triage, postmortem template
3) Save the prompt template that produced it in the prompt library.
4) Next time: search once → jump directly → reuse the prompt.

That’s the difference between:

“I remember ChatGPT said something…” and
“I can retrieve it in 5 seconds.”

Keyboard shortcuts (for people who hate mouse gymnastics)

These are the shortcuts I personally care about:

j / k or ↑ / ↓ to move between messages
b to bookmark a message
Shift + b to bookmark the whole conversation
Enter to open message details

Privacy stance (because this matters)

I built this to be private by design:

The goal is to sync only what you explicitly save (bookmarks + prompts).
Not your entire conversation history.

If you’re evaluating extensions, read permissions and data handling like a paranoid adult.

Compatibility

Works in Chromium-based browsers that support Chrome extensions: Chrome, Brave, Edge, Arc

Try it

If your ChatGPT usage produces real value, you need a way to keep that value.
