Dayflow – A git log for your day

In plain words

Dayflow is a macOS app that automatically tracks work activities by analyzing screen content rather than just monitoring open applications. Using visual language models, it creates a semantic timeline of the user's day, categorizing time spent into specific tasks like code reviewing, debugging, or reading documentation. This eliminates the need for manual time logging and provides detailed insights into how time is actually spent, aimed at developers and knowledge workers who want accurate activity tracking.

The automatic work journal/time tracker. Privately turns your screen into a timeline of what you actually accomplished. Open-source and local-first. - JerryZLiu/Dayflow

Dayflow understands the work you do on your Mac and turns it into a clear timeline of your day. Built from the ground up for privacy, it’s open source, local-first, and can run entirely with local AI. Dayflow turns raw screen activity into a chronological timeline of what you actually did, so you can reconstruct the day without timers or manual notes. See a GitHub-style activity grid of your day, plus yesterday's highlights, today's priorities, and blockers, so you can walk into standup with the update already written. See your week at a glance: when you were focused, where time went, which apps dominated, and what pulled you off track. Ask questions about your day/week/year and get answers…from github.com

In the maker’s words, at launch

Hi HN! I've been building Dayflow, a macOS app that automatically tracks what you're actually working on (not just which apps you have open). Here's what it does: - It creates a semantic timeline of your day; - It does it by understanding the content on your screen (with local or cloud VLMs); - This allows you to see…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Term.everything – Run any GUI app in the terminal▲1,094

  I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

  I recreated Windows XP as my portfolio▲1,032

  Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
