Hey we are Housecat. I've spend the last 15 years building dev tools at Heroku, Convox (YC S15), and Segment. Dev tools have gotten insanely good over the decades, now we're working to level up productivity tools for everyday work. Housecat is an email inbox running on an single-tenant agent computer with a durable workflow engine and connections to common tools for day-to-day work. My primary workflow with the product is for customer support: get a support email, trigger a triage process, open a GitHub issue, spin up a coding agent to fix it, and update the customer along the way. All from the same UI and sandbox. We've experimented with lots of different approaches to new workspace tools, and learned that many people still need a great GUI. We've landed on the email inbox as a very familiar and permanent surface and are building tools and automations directly inside it. Under the hood every user gets their own single-tenant sandbox VM and persistent SSD on exe.dev. User connections to Google, Slack, GitHub, etc. are managed in an external service so the VM and agent are subject to external governance and don’t have direct access to secrets. Durable workflows are built on DBOS.dev. Running interactive and deterministic workflows directly inside an email couldn’t feel more different than chatting about emails in Claude.app. The app is built on HTMX, Unix, Go, and SQLite. The app is source available to users and the Linux VM is fully open for a user and their agent to poke around. You can try it out at https://home.housecat.com/beta. It requires a Google / Gmail connection for the email app, which you can revoke any time. We'd love to share more and learn how the community here is managing email, agentic chat, and custom workflows for their work.

Computable
Hey we are Computable. We spent years building trading infrastructure at Jump Trading and Coinbase. From that point of view, compute looks like energy markets before 2000: everything trades through private bilateral leases, there’s no visible price, and nothing can be resold. The same H100 rents at a 2x spread depending on who’s asking, and once you sign a 24-month lease, it can never change hands. So we built a market for GPU nodes, sold by the calendar week. Here are three things you can do on it that you can’t do anywhere else: - Buy exactly the weeks you need. Three nodes for the last two weeks of October means you pay for those two weeks and walk away when the run is done. You don't have to commit to 6-24 months, and there's no flexibility premium. - Sell back what you don’t use. If your plans change, unused weeks turn back into cash: we keep a market quote posted on every position, so there’s always a price to hit. - Buy (or sell) the future. Lock January in July at a price you set, so the cost of a future run is known before another 40% H100 rate jump makes it not. The first auction is live now at https://market.getcomputable.com: a block of nodes, August through the end of January. Bidding closes July 31. The bids are sealed. You bid how many nodes, which weeks, and your price. Every clearing price gets published after settlement, because nobody knows what a GPU week is worth and we want the prints to exist in public. Happy to go deep in the comments on anything, including the clearing mechanism, which is a packing problem and was fun to design!
A canvas-based note taking and organizer app
So I've been working on this app for a very long time now. Started off by wanting an app that separates long form notes from short form notes visually and keeps everything organized on a canvas. The app features: -Sticky notes for quick, small notes and A4 notes for long form documents -A quick mode that uses local storage to quickly open the app and jot down a thought on the canvas -A PDF export option that exports your notes into 3 custom designed PDF styles -Visual hierarchy to replicate file structure instead of a linear fashion, where your files are notes, stacks are folders and labels are names for your folders Would love to continue working on this app if you guys like the concept.

Real-time avatars that change emotions as you talk
Hey HN, we're Ben and Caoimhe, cofounders of Anam. We build interactive avatars and just shipped our latest model, cara-4. This is the first avatar model which can naturally shift emotions and expressions during the conversation; a feature we’re calling “Director Notes”. The way it works is relatively simple: we have an LLM provide cues such as [laughter], [sad], [warm] interleaved with the speech, which we then condition our animation model with. To test it out, we commissioned a blind study from Mabyduck.com with 200 participants, 1,600 rated live interactions across six criteria. Cara-4 ranked first overall and was preferred head-to-head over each competitor on overall experience, lip-sync, visual quality and “naturalness”. On latency, measured across a full week of live traffic, end of user-speech to first video frame is ~1.2s median. The avatar model's own share is just ~100ms; most of the rest is waiting on STT, LLM, TTS or various forms of buffering (an unsung latency killer). How the model works: cara-4 has a two-stage design, a diffusion transformer turns audio+text into motion embeddings (head pose, gaze, lip shape, expression), and a rendering model applies those to a reference image, so new faces works without finetuning. Why faces at all: they carry emotional signal that text and voice don't, and they're a more accessible medium. Anam started in part from Ben watching his gran struggle with her iPad and thinking there should be a face she could just talk to. If you’d like to test it for free go to anam.ai
