Stop spamming inboxes. Start trusted conversations.
What it does
How much time do you waste guessing who to target in outbound, only to hit dead ends or low-response cold messages? • Cuts through the noise to show you who’s quietly evaluating solutions like yours right now • Reveals hidden warm intros you didn’t even know existed (one user found 21+ strong paths in minutes) • Makes outbound feel more like warm outreach → more replies, shorter cycles, fewer dead-end calls More here: https://www.loom.com/share/a684763af9de4890a4c28be2ed31b5b8

- MSMake senders work to get into your inboxJul 2026 · captchainbox.com · ▲44
Hi HN :) really excited to share this with you. 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…

Hi HN! I'm Louw, founder of the enterprise insurtech scale-up Root[0]. Over the last 8 years, my inbox has been flooded with unsolicited emails, especially since early 2023. Recruitment services, outsourced software development agencies, and a crazy amount of lead generation services (thanks, Apollo!) drowned my inbox. To solve this, I created Unspam. Initially, it was a simple tool for myself and fellow founders to reduce noise. And it worked — about 10% of my emails were swiftly and accurately categorized as unsolicited messages. Given its success, I've decided to package and share Unspam…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
