I've been casually vibe coding this since Wednesday. I think it's quite a powerful idea. I have zero experience with making an extension, but it's the first time AI called a project 'seriously impressive' when I threw Gigi's idea in there.

So far I have come up with a few additional features but the spec would be this at a minimum:

OTS via NIP-03

Blossom for media

3 different types of archiving modes:

Forensic Mode: Clean server fetch, zero browser involvement = no tampering

Verified Mode: Dual capture (server + local) + automatic comparison = manipulation detection

Personal Mode: Exact browser view including logged-in content = your evidence

Still debugging Blossom integration and NIP-07 for signing extensions seems tricky. The only caveat is you would need a proxy to run verified + forensic modes, as CORS will block requests otherwise. Not sure how that would be handled other than hosting a proxy. Once I have a somewhat working version I may just throw all the source code out there, I dunno.

Some test archives I've done on a burner account using this custom Nostr archive explorer here.
