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.

New JD for software engineers: Loop Engineering Boris Cherny, who built Claude Code, said: "I don't prompt Claude anymore. I have loops running that prompt Claude and figuring out what to do. My job is to write loops." Straight out of latest newsletter, another good summary of how engineers' roles are shifting... The ultimate automation of engineers' job and any operations job using AI loops is a good answer to mangers, investors and shareholders. Especially in the async organization like Babylon Labs, where I have colleagues in 10+ time zones.

Combine notes on an infinite canvas and export sequences as PDF pages.

I'm happy to announce "Mash" A local first browser based app for compiling notes and ideas on an infinite canvas. Make as many notes as you want, drag and drop to "Mash" them by combining. Create "sequences" that allow you to export a pdf with each sticky as it's own page. Drop in PDF or DocX or images to easily browse the file and select your favorite clippings to a new canvas, and manipulate them or export them how you want to. Drop a GIF to get all the individual frames. Mash features a roster of cute food themed mascots because this is your infinite textual stove top. Pull in some ingredients, mash them together, stitch them together, arrange them into a flow chart, whatever you find useful, and then get out quickly. Mash is for the little moments that speed up work, and the spontaneous thoughts that inspire new directions. There is no fancy AI feature, no data collection, no login, just a utility for you. Free open source licence. Run it offline if you want
