Show HN: I made ChatChain, a chrome extension, auto adds timestamps to ChatGPT

https://www.chatchain.chat/
2•tzvipi•7h ago
Hey all!

I built a chrome extension that automatically adds timestamps to your messages sent.

Test it out yourself:

User: yc@chatchain.chat pw: 1a3g5b7g

ChatGPT is smart enough to pick up on it, and it can actually respond to things like "What did we talk about yesterday at 2PM?", or "Summarize everything we discussed since 4PM"

Enjoy! Please leave a review, it means a lot to me!
