Fatebook – Superforecasting in your Slack
Hey HN! I’ve been building Fatebook for the past couple of months. It’s a slack bot to help your team make and track predictions, right where you work. I see forecasting as anti-bullshit technology: - It gives you truthseeking incentives - You communicate your uncertainty as a probability, which is way clearer (70% is better than “probably”) - You can aggregate forecasts to get wisdom of the crowd effects - You can see everyone’s track record, and pay more attention to people who are consistently accurate I’m a fan of prediction markets [0] and forecasting platforms [1]. But predictions on…

What it does
Track your predictions, right where your team works
Fatebook offers a quick, clear view into predictions across the organization. It's not just informative, it's engaging too. We absolutely love this thing so far. It just came in handy today with "if we deploy XYZ as a beeta feature will we decide to deploy it universally?" Getting a quick sense of that probability is great for deciding whether to put in the work on the feature! Anyone in the channel where you asked the question can forecast. The app only receives messages where you use the /forecast command or mention @Fatebook. Yes, only your team can see forecasts made in your Slack workspace. If you create a question in Slack, you can also see it on fatebook.io if you log in with the…from fatebook.io

XBeast2024 · xbeast.io · ▲228A few weeks ago I realized i was spending way too much time trying to write quality posts for Twitter. So I decided to look into scheduling tools which could help me automate my writing. I tried a few, but none of them satisfied me. Either the interface was way too complicated or the features i wanted were just not there. Finally, after some time I gave up… and instead I decided to just do it! I hacked up a quick prototype in a weekend. Tried it out - it worked!! Mostly.. I fixed some bugs, made a nice UI, and now (3 weeks later) I think I built one of the nicest scheduling tools out there.

Hey guys, I left my PM job in December to learn how to code. The plan, - Build something that "I" could build with my background (I haven't studied CS) - Something that already existed and I used so I didn't have to spend time finding PMF Over the past 4 months I've been building howsthisgoing.com (a standup bot for slack with AI summaries). My ex-employed signed up in May & I got another customer through a university batchmate sometime in June (the company he's working at). However, since then it's mostly been 0 new customers, I get roughly 6-10 views on my site daily. The bot and my…

Heya HN, I've been working on a reddit-like platform as my primary side project for the last few years. Doing a (very) soft launch today, mainly because I want to use it to encourage discussion of alternatives. How non.io works: 1. Free to browse, paid to interact. 2. Minimum subscription is $2 (though you can choose more). I take $1 to run the servers, everything left gets split evenly between everything you upvote that month. It's a simple model, but I hope it's a better one than the freemium model we've been relying on for the last few years. Fundamentally I feel like any ad-supported…
