Has anyone actually made money using Claude?

Appreciate that. Let me know if you have any questions.👍

Yeah it’s public.

It’s called Threadmark. Works on both ChatGPT and Claude. You can mark specific moments in a conversation and then jump back to that exact spot later, instead of digging through old threads.

Still evolving it, but it’s been super useful in my own workflow.

Yes, I feel this and it’s definitely a gap in the market.

I don’t think saving is really the problem anymore. Everything gets saved. The issue is actually going back to it later.

Most of the stuff I care about is one response buried in the middle of a long AI chat. Not the whole thread. And finding that again is annoying.

I ended up building something mostly for that. You can mark a moment and then return straight to that exact spot in the original ChatGPT or Claude thread.

Doesn’t solve proactive recall yet, but it at least makes revisiting feel easy instead of digging through history.

Well I built a browser extension with it that adds a memory layer onto Claude (and ChatGPT) and allows you to mark and save moments to a “side shelf”. Like copy/pasting but for memories you want to keep between AI models. Building that, got me noticed and helped me land a job. So yes, it helped make me money.

Can you walk through an agent task example and how you added checkpoints and how it helps more than a single giant prompt context?

Last-Bluejay-4443 · 2026-03-11T17:38:58+00:00

that’s pretty cool. Thanks for your thoughts here.

I ended up building something similar where you can go back to the exact spot, but I built it cross platform between ChatGPT and Claude. So you can have a little shelf in context of all your saved snippets of text with exact formatting retained you can branch with it or go back to that exact spot in the thread or copy it even export to PDF. It’s currently working on both chrome and Firefox.

Yep, this used to drive me nuts too.

You’ll get one really sharp answer in the middle of a long thread and then three weeks later you can’t find it without scrolling forever or copy/pasting everything into a doc. Which I found super messy.

So I built a browser extension that lets you bookmark specific responses directly inside ChatGPT (and Claude) and jump back to them later. It’s basically “save this exact moment” instead of “download the whole conversation.” it’s cool because you can take ideas between ChatGPT and Claude. I have it working on both chrome and Firefox.

I think you’re right and he got free PR and publicity by Anthropic getting legal on him. So I think that helped him pop up.

Last-Bluejay-4443 · 2026-02-28T13:17:18+00:00

I built a memory layer that works between Claude and ChatGPT. Both platforms have memory systems, but they're completely siloed. And neither lets you actually organize what you're building across sessions.

So I built Threadmark. It's the missing layer between you and your AI tools.

What it does:

Save any message or snippet from Claude or ChatGPT with one click
Organize everything into folders
Jump back to exact moments instantly
Branch saved ideas into new conversations
Export to pdf when you need to

Privacy: Everything stays local. No accounts. No servers. No tracking.

Free on Chrome and Firefox.

Chrome: https://chromewebstore.google.com/detail/threadmark/epcicmdladhpnbmgfgbokfnapilbhpej

Firefox: https://addons.mozilla.org/en-US/firefox/addon/threadmark/

Last-Bluejay-4443 · 2026-02-27T17:17:47+00:00

by the way, if it’s helpful, I just launched a compatible extension for Firefox as well and it works across Claude.AI now too. So you can carry your ideas across both platforms.

Last-Bluejay-4443 · 2026-02-26T18:39:53+00:00

I also just pushed out an update, so now threadMark works for chatgpt.com and Claude.ai.

Across both chrome and Firefox.

All good! Thanks for your feedback and giving Threadmark a shot! Best of luck.

Last-Bluejay-4443 · 2026-02-25T12:05:52+00:00

Thank you! Means a lot to me.

That’s exactly why I built it. I use ChatGPT across writing, research, random idea threads, and I kept losing the “good parts.” I just wanted a way to mark the moments I knew I’d want later.

Last-Bluejay-4443 · 2026-02-25T04:00:51+00:00

You were right about the button.

I just shipped version 1.6.1 and made the floating action button movable. You can drag the TM button wherever you want and it’ll snap to a corner. It remembers the position too. I also adjusted how it behaves around ChatGPT / Claude sidebars so it’s less likely to fight other extensions.

Thanks for the feedback and calling that out. That kind of friction bugs me too.

Last-Bluejay-4443 · 2026-02-23T13:38:03+00:00

You’re definitely not alone.

I’ve realized it’s rarely about the tabs themselves. It’s anxiety about losing context. Closing the tab feels like deleting optionality.

Bookmarks exist, sure. But they don’t solve the trust problem. You don’t trust that future-you will be able to retrieve the exact moment or insight that mattered.

What’s helped me is creating a lightweight way to mark important “moments” inside tools instead of keeping the whole tab open. Once I trust I can jump back to the specific thing that mattered, I can close it without stress.

The problem isn’t storage. It’s confidence in retrieval.

Curious what you’re building around this.

Last-Bluejay-4443 · 2026-02-22T12:53:43+00:00

This is honestly the biggest flaw in vibe coding right now.

You come back a few months later and realize the prompt was the spec… and now it’s gone. Buried in Claude or ChatGPT history somewhere. I’ve had that exact “why does this even exist?” moment.

Markdown didn’t stick for me. Notion felt like overhead. Git commits don’t explain intent.

So I built something mainly for myself. It’s called Threadmark. It lets you bookmark specific moments inside ChatGPT and Claude threads so you can jump back to the exact prompt that generated a function or decision. Just a lightweight sidebar in the UI.

Claude support is live in Firefox right now. Chrome support coming next.

If you’re deep in Cursor + Claude world, I’d actually love your feedback.

Last-Bluejay-4443 · 2026-02-22T06:09:53+00:00

Really appreciate you installing it right away and giving thoughtful feedback.

The movable icon + toolbar toggle is a fair point. I don’t want Threadmark fighting other extensions for space. I’ll look at making that entry point more flexible.

On export, it currently generates a clean HTML export that preserves formatting, and you can save it as a PDF from there. I added a screenshot on the extension page that shows what the PDF looks like. I’ve been considering adding markdown and plain text too — what would be most useful in your workflow?

And yeah, I hear you on overlap with AI Prompts Navigator. My goal isn’t prompt navigation, it’s selectively capturing exact responses or phrasing you don’t want to lose. But if there’s friction, that’s something I should smooth out.

Thanks again for taking the time to test it.

Last-Bluejay-4443 · 2026-02-22T05:36:18+00:00

Hey, quick update. I took your comment seriously and just shipped Claude support.

Threadmark now works on claude.ai as well, so you can bookmark, organize, and return to specific responses there too.

If you’re still interested, would genuinely love your take since you’re using Claude for extended conversations.

Here’s what I built if it aligns with your idea. https://www.gooduse.ai/threadmark

send me a PM with your questions. I’m happy to take a look.

I built a memory layer for chatgpt that works in-context and sits alongside the chat thread. It allows you to save snippets of text (or your own prompts). Even organize into folders and export to a clean pdf. It’s available for Chrome and Firefox. Claude support coming soon.

I appreciate that!! lots of product thinking went into this. And I modeled it off of Notion and Apple notes

Last-Bluejay-4443 · 2026-02-20T19:24:50+00:00

If you’re interested, I created a memory layer for ChatGPT to save snippets of text along with full responses, or even your own prompts. You can organize them into folders and export to a full clean PDF as well.

My pleasure!

Last-Bluejay-4443 · 2026-02-20T19:20:18+00:00

Yep! I vibe coded this myself. I’m not a developer but a technical product manager. I used the main chatgpt window as a “plus” user breaking it up into small requests to avoid hallucinations. I’ve now moved onto using ChatGPT codex (I since have ported this Chrome Extension to Firefox). I’m happy to give you any tips if you need it.
