Show HN: Open source alternative to Perplexity Comet https://ift.tt/qxizDLf

Show HN: Open source alternative to Perplexity Comet Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://ift.tt/GvjWCtk --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad company, so no weird incentives. Your data stays on your machine. You can use local LLMs with Ollama . We also support BYOK (bring your own keys), so no $200/month plans. Another big difference vs Perplexity Comet: our agent runs locally in your browser (not on their server). You can actually watch it click around and do stuff, which is pretty cool! Short demo here: https://bit.ly/browserOS-demo --- How we built? We patch Chromium's C++ source code with our changes, so we have the same security as Google Chrome. We also have an auto-updater for security patches and regular updates. Working with Chromium's 15M lines of C++ has been another fun adventure that I'm writing a blog post on. Cursor/VSCode breaks at this scale, so we're back to using grep to find stuff and make changes. Claude code works surprisingly well too. Building the binary takes ~3 hours on our M4 Max MacBook. --- Next? We're just 2 people with a lot of work ahead (Firefox started with 3 hackers, history rhymes!). But we strongly believe that a privacy-first browser with local LLM support is more important than ever – since agents will have access to so much sensitive data. Looking forward to any and all comments! https://ift.tt/X6K5JaF July 10, 2025 at 11:03PM

Show HN: Activiews – A privacy-first fitness alternative for Apple users https://ift.tt/egchlnP

Show HN: Activiews – A privacy-first fitness alternative for Apple users Hi HN, I built Activiews as a fitness alternative for Apple users who want a simpler, more private, and more visual way to view their workouts, with a heavy focus on maps. The app reads from Apple Health and Watch data without requiring an account or sending anything to the cloud. I built it because I wanted a fitness app that: - Has no social network features - Does not store my data on their servers - Doesn't require an account or login - Stays lightweight and free of bloat - Is simple to use, with a focus on customizable workout visuals Core features: - Customizable workout maps and shareable cards - Flyover route animations - Calendar heatmap showing activity over time - Offline-first, data stays on device, no login/account needed - Dark/light themes, map styles, unit system, and accent color customizations - Reads data directly from Apple Watch - Localized in 13 languages - €0.99/month or €24.99 lifetime It’s built in Swift & SwiftUI using native APIs and focused on performance and privacy. I’d love your feedback, ideas, and comments. App Store: https://ift.tt/t1dO8RN Website: https://activiews.xyz Thanks! http://activiews.xyz/ July 11, 2025 at 12:28AM

Show HN: Stravu – Editable, multi-player AI notebooks with text, tables, diagram https://ift.tt/y60H3rV

Show HN: Stravu – Editable, multi-player AI notebooks with text, tables, diagram Hi HN! I'm Karl one of the co-founders of Stravu. ( https://stravu.com ) Using AI for work 24x7, we realized that four things would make AI more useful for us and a lot of other power users and teams: Editable output: AI gives output that is half right and our only option was to either keep chatting laboriously or copy it to a Google Doc. We made Stravu so you can edit what the AI says in chat or in an attached notebook. Everything editable. Approve AI changes: When AI makes a change to some text, you can't tell what changes. We put Red/Green diffs that you can approve into Stravu. Unify text, tables, diagrams: We were jumping between tools to work with AI on text, tables, diagrams, etc.. Just because Microsoft did that 30 years ago, doesn't mean it makes sense now. We made Stravu so you can work with AI across text, tables, diagrams, (and 2x2s, formulas, more soon) and have them inform each other. Actual multi-player team collab with AI: We couldn't collaborate as a team in AI (even with the ChatGPT Teams plan). We wanted to be able to chat with AI together as a team or see the changes AI was making in the canvas/notebook together and edit together. So we made Stravu support multi-player collaboration in every aspect... chats, notebooks, text, tables, diagrams..etc. Some of the use cases of our current Beta customers include: scrum teams doing feature/customer/competitive research and feature definition, account teams building vertical/geo/account plans, consultants and investment teams working on market/company analysis. We are currently in beta and actively iterating based on user feedback. Please try it out at: https://stravu.com We highly value your feedback! July 9, 2025 at 07:47PM

Driving Muni’s Comeback Together: May Marked Highest Ridership Recovery Month

Driving Muni’s Comeback Together: May Marked Highest Ridership Recovery Month
By Glennis Markison

You're helping us drive Muni’s strong recovery. Several routes now see more riders than they did pre-pandemic. In May, the 22 Fillmore saw 127% ridership recovery. Our teams have been working hard behind the scenes to make our transit system fast, frequent and reliable. We’re thrilled to see the results: more and more people choosing Muni. May marked our highest ridership recovery month since the pandemic began. And the data shows even more milestones – a comeback you drove just as much as we did. Weekend ridership reached 97% of 2019 levels – our highest weekend numbers since the pandemic...
