The average person uses 11 apps daily and loses 25% of their time to context switching. That's $25K wasted for every $100K of salary, moving information around instead of doing real work.
Sugarbug is a workflow intelligence platform that connects the tools you already use โ Linear, GitHub, Figma, Slack, Notion, calendars, email, and more โ into a single living knowledge graph. Every signal is ingested, classified, and linked automatically. Tasks, people, and the relationships between them are mapped across every source.
The longer Sugarbug runs, the smarter it gets. It builds living profiles of the people you work with from every interaction, so you always have context on who's involved in what. Meeting briefs, status updates, and cross-tool summaries are generated from real data โ ready before you need them, without hunting across nine tabs.
The system is adaptive: it learns which sources matter most and adjusts how aggressively it monitors them based on actual activity patterns.
Sugarbug uses a provider-agnostic AI architecture โ bring your own LLM. Pick the model that fits your needs, swap it whenever you like. No vendor lock-in.
Built for product managers, design leads, and founders who spend their days stitching together updates from half a dozen apps before they can actually do their job.

SugarbugSugarbug's answer:
Most tools in this space are another dashboard to check. Sugarbug isn't a destination โ it connects the tools you already use and builds a knowledge graph across all of them. It doesn't replace Linear or Notion or Slack. It makes them work together by linking every signal, every person, and every task into a single picture. And that picture compounds โ the longer it runs, the less work you do to stay informed.
Sugarbug's answer:
Competitors tend to solve one piece of the problem โ a better notification layer, a smarter calendar, an AI summariser. Sugarbug solves the structural problem underneath: your information is fragmented across tools that don't share context. Instead of adding another app, Sugarbug sits behind the ones you have and does the stitching for you. Meeting briefs, status updates, people context โ all built from real data across every source, not from a single silo.
Sugarbug's answer:
Product managers, design leads, and founders who run on more tools than they can keep in their head. People who spend a quarter of their week moving information between apps instead of doing the work the information is about. If your day involves checking Linear, then Slack, then Figma, then Notion, then your calendar just to prepare for one meeting โ Sugarbug is built for you.
Sugarbug's answer:
Two people โ a Head of Design and a Head of Product โ were drowning in the same problem: too many tools, too much context switching, too little time for the actual work. Every existing solution was either another app to check or an AI wrapper around a single tool. So they built Sugarbug as a shared brain โ one system that watches everything, understands the connections, and does the legwork so they can focus on what matters.
Sugarbug's answer:
Native app across macOS, Windows, Linux, iOS, Android, and browser. The AI layer is fully provider-agnostic โ bring your own LLM, no vendor lock-in. All integrations connect via official APIs over secure private networking. No Electron.

Let's hope this is going to help me solve some more Project Euler [1] problems! [1] https://projecteuler.net/. - Source: Hacker News / about 2 months ago

I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 7 months ago
I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago
