Like ChatGPT or Claude, but it runs in the cloud, remembers everything you give it, and comes loaded with skills. Hand it a job tonight and read the answer in the morning. Use it on your own, or with your whole team.

Roma is the task app where AI gets to work for you. Simply type or say anything - an idea, a thought, a bunch of different things you need to remember - and Roma starts the work from your pocket. It's connected to your calendar, your email, your files, so it knows what to do next before you even ask.

Touchy is your personal AI assistant that lives on your iPhone. One button press and you're talking to an assistant that sees what you see, remembers what you tell it, and takes action across 1,000+ apps--so you can get back to living in the moment.

Developers don't run one coding agent anymore. They run fleets of them — for hours, sometimes days — across laptops, servers, and sandboxes. Keeping track of that work is the new bottleneck: which agent is blocked, which one finished, which terminal is it in, and why did everything die when the laptop closed. Herdr is the open-source home for that work. A background server owns the agents' terminal sessions on each machine, so the work survives disconnects, closed lids, and dropped SSH. Herdr detects each agent and turns the chaos into an attention queue — working, blocked, done, across every project — so you look only when an agent needs you. Every client is just a view: the bundled terminal UI, SSH from another machine, your phone. Close one, open another; the work never stops. Software can drive it too: a CLI, a socket API, and a plugin marketplace that passed 500 community plugins in its first month. The runtime is Apache-2.0 and stays open. Four months after launch: 25k GitHub stars, 340k downloads.

Egoist Machines is building infrastructure for a world where your personal context belongs to you, rather than to the apps and AI companies you use. Today, every assistant and consumer app builds its own version of you. We think that architecture is backwards. Your context should live with you, persist across products, and be available to any model, app or agent you choose. AI Passport is the first layer of that infrastructure. It brings the context you generate across AI assistants and everyday apps into one portable profile you control. Tell ChatGPT something and Claude can already know it, for example. Switch to a new product and it can understand you from the first interaction, without the new company needing to own the underlying data. Apps integrate through Sign in with AI Passport, requesting only the context they need for a specific purpose and duration. Users can see what is being accessed and revoke that access later. Underneath, we have built our own memory infrastructure for fast, compact per-user retrieval and permissioned access. We are distributing AI Passport directly to consumers through first-party products, while integrating it into consumer applications with existing distribution. Every new product that uses Passport gives users another reason to maintain their context there, and every additional Passport holder makes the context layer more useful to developers. The next step is to build a true Egoist Machine: an intelligent system whose memory, incentives and actions are governed by the individual it represents. We call it Digital Domovoy, the hardware extension of AI Passport. Instead of your most personal context ultimately living on somebody else's servers, it lives and is processed locally on hardware you control. AI Passport becomes the permission layer between that private local context and the cloud models and internet services you choose to use. Our North Star is the Egoist Machine: an intelligent system whose memory, incentives and actions are governed by the individual it represents.

Almanac is an AI agent that deeply understands your work. Today people rely on a stack of productivity tools to hold the context of their work including todo lists, issue trackers, wikis, and CRMs. All of them have to be updated by hand, and none were built for AI. Almanac maintains its own self-updating productivity suite for you. This gives it an absurdly good understanding of your work, based on which it proactively gets things done for you. Almanac starts with individuals, but it's built for teams. As more of a team connects their work, the agent gains shared context across everyone, so it understands not just what you're doing but how the whole team's work fits together.

We want to bring AI agents to a billion people. To do this, we believe it needs to be 1. proactive and 2. personal. A billion people already carry the right device, but none of them have the right connector. Moonshot is personal intelligence that lives on your iPhone and listens to you 24/7. It continuously builds up a greater understanding of you through constantly listening and building context. It just pays deep attention, the way a good friend does. Through this, Moonshot monitors your conscious and subconscious life, figuring out what you need before you know, reminding you about open loops, identifying life and emotional trends before you recognize it, and covering a lot more of what we gloss over in daily life. For fifty years, software has waited to be asked. We think tools are just good enough to flip this, and the next great software will provide value before asking for something first. We're doing it through Moonshot. Our thesis is simple: you're only living half your life. The half that you actively remember. The other half just evaporates into your subconscious: what you said, felt, promised, and forgot. It's the more interesting half, and until now nothing could catch it, making it not actionable. Moonshot catches your subconscious half and understands you well enough to take actions on your behalf. Take life personally. The iOS app is designed around ambient listening and clear user control. Short microphone chunks are sent securely to Moonshot's private transcription service and deleted when transcription finishes. Text and selected context can be sent through Moonshot's server to a model when the app needs to understand a moment. Nothing leaves without your yes. The privacy policy explains every data path, stored copy, permission, and deletion control in detail. Moonshot is in early access. Join the waitlist to hear when access opens, read more about the team and product on the About page, or use the Contact page for a direct written response from the Moonshot team. Let's make it a Moonshot.

An adaptive training coach to help runners, cyclists, and triathletes set and achieve goals. It adapts your training, recovery, and nutrition to how your body is actually responding.

Sidekick is an AI agent that runs custom manufacturing operations over text. Workers text a problem, photo, video, or voice memo and get an answer from the shop's own documents. It reads live machine data and acts on its own: flagging issues before they become downtime, opening and routing work orders, and placing purchase orders. No app, no login. These shops run on tribal knowledge: a handful of veterans know how every job is set up, and they are retiring. Sidekick learns from every message it handles, so answers outlive the people who gave them, and shops run 15% more jobs with the same crew. Sidekick captures it as a byproduct of the work, in an industry that was never documented.

Companies today are growing faster than ever with smaller teams. The best AI-native companies don’t just need more users - they need more of their users becoming power users. Userlens makes it possible for lean teams to drive product adoption proactively, at scale. Userlens is building the AI product adoption expert. Our goal is to help every user at every company get more value from the product they already use. Most teams still rely on onboarding flows, lifecycle emails, support docs, and reactive CSM outreach. Userlens breaks that ceiling. Lumi watches how users actually use your product, spots when they’re ready for the next feature, workflow, or habit, and nudges them at exactly the right moment.

Logical is a desktop AI that acts as a proactive and largely promptless copilot, designed to reduce the friction of using AI for everyday tasks. It transfers context across apps, and allows taking action on many apps with just a few clicks. Logical can assist with drafting emails, writing docs, noting meetings and can even automatically detect action items. Need to prompt? Logical can understand intent in much fewer words than a regular chatbot. Plus, user data is never sent to Logical servers. Logical is the AI resurrection of Clippy, but actually good.

Email sucks. It takes forever to go through, and hiring an assistant is costly and invasive. Friday is building the assistant that learns how to predict the action that you will take on your emails, and does it for you. Today's email products try to help you go through your emails a little faster, but if you have to get through 1000 emails, those products doesn't do much for you. The reality is, most of the emails you get don't require you to personally look at them. Freestyle completely eliminates the need to check those emails, and handles them all at once for you, immediately. Freestyle is here to file away spam, sift through newsletters for important tidbits, text you important notifications, and reply to mundane emails, so that no matter how many thousands of emails are in your inbox, you'll just be left with the few emails that actually require your personal touch. Getting this right is difficult, so everyone else settles with trying to help you go through your email twice as fast. If you want to go 100x as fast, you shouldn't spend even a second on useless emails. Freestyle gets this right, bringing the elite experience of having a professional assistant to the entire world.
