Due to bike-induced concussions, I've been worried for a while about losing my memory and not being able to log back in. I combined shamir secret sharing (hashicorp vault's implementation) with age-encryption, and packaged it using WASM for a neat in-browser offline UX. The idea is that if something happens to me, my friends and family would help me get back access to the data that matters most to me. 5 out of 7 friends need to agree for the vault to unlock. Try out the demo in the website, it runs entirely in your browser!

While traveling abroad, I was robbed and forced to withdraw $500 from an ATM. My bank told me that this wasn't recoverable since it was not via their ATM. I asked GPT what I should do and it informed me to write a complaint to the FDIC, which was not 100% correct, but they routed it to the CFPB. GPT then wrote the complaint for me that ultimately got me a call from the bank's executive office which returned the stolen funds to my account after another 'investigation'.
