Protect your email and calendar by requiring unknown senders to solve a CAPTCHA or pay a fee.

Hi HN, The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels have been abused like this. Captchainbox applies the idea of proof-of-work to email. If a sender is willing to do a bit of work to reach you, the message is more likely to be worth your time and the sender more likely to be real. The work is a traditional captcha. You can also set a pay-to-deliver amount if you want more friction. The proceeds of the delivery payment after transaction costs go to the Internet Archive and the EFF. The tool curr

Multisig wallet for managing assets across multiple blockchains on Sui.
@botanicles1 · X
Hey, @ikadotxyz @iamknownasfesal @d3h3d_ I asked AI a bunch of questions and it made something pretty cool; a multisig/multichain policy wallet using Ika on Sui. Test site: github repo: This is completely vibe-coded. It’s got a little AI stank on it so I named the wallet stINKy. I acted only as a business analyst, and a lazy one at that. It’s just incredible what came out of $250 of Fable and a $20 OpenAI plan over the course of a couple weekends. You can use it on Sui testnet or mainnet(though I wouldn’t). It's got: 1. Governance tab for adding/removing signers, setting spend and admin thresholds, spend limits, timelocks, blocklist, etc. 2. Overview tab to show current derived addresses and balances, current policies, sui/ika reserves for transactions, vault deposits for sui 3. Send tab - start a send tx 4. Requests tab - for signers to approve/veto spend or admin requests 5. Address Book tab 6. A cute little squid with a couple sti

Hey HN, I'm really excited to share Emra with you. The yc description would be: It's like "Notion meets Lovable". It's a workspace where you build full apps using AI and every app sits on one shared database and service layer. Generated apps are always editable, and (coming soon:) can interact with each other in the workspace. I'm of the opinion that the cost of software will go rapidly to zero (I don't think that's too surprising to any of you), but there will always be room for effort and creativity. Emra is essentially built for the future where every person is a developer. Essentially personal software for everyone. So far I've built notes apps with a 3d graph view to see connections, a video editing app and a canvas design tool (figma clone) with export capabilities, as well as a collection of project management tools and games. Right now the most satisfying thing is being able to fix a bug I run into in around the same amount of time that it takes to send a bug report in any tr
