I don't know... I know a few people who inherited enough money to be idle and they don't seem particularly happy with their idleness. Could of course be the social pressure we live in, and that could change if we're all idle.

Show HN: Beeminder for Effective Charities

christoph123 — Fri, 27 Mar 2026 16:26:23 +0000

Side project that'll hopefully raise some money for charities!

Behavior change research shows that putting money on the line makes it much more likely that you'll stick to your habits. It's not being used much though because most people don't want to put money on the line haha

We think part of the reason is that your money is traditionally going to the startups (eg Beeminder, Forefeit). We solve it by donating it to effective charities.

I built it as a pretty minimal PWA to get around app stores and allow browser use. Apple makes it a bit hard to install (open in safari > share > save) but I wouldn't have done it if I would've had to go through all the app stores.

I built mine with all kinds of privacy features built in: from never storing raw data to always allowing to review before sharing anything to always offering to pause, excluding apps, deleting data, opt-in for social features, …

So spyware in the sense of getting information without the employee knowing would be impossible and not something I’d ever want to do.

It does enable transparency on a very abstracted level: your team could see a six bullet point summary of your day if you opt in. I believe this kind of transparency can actually help more teams go remote, cut down on sync meetings, etc.

I’m currently experimenting with a feature that shows relative time spent only, not absolute - so e.g. 30% on project X, 20% on admin, etc. That could be the sweet spot on visibility vs privacy.

A substack for 80/20 life advice and behaviour change.

https://euzoia.substack.com

Full project: https://euzoia.org

Tried to be super low-tech: Notion, super.so, Spotify creators, riverside.

Now thinking of building an email-based agent for behaviour change accountability. Would love any pointers to good UX for email-based AI assistants.

An AI based time tracker: reconstructs your day from whatever it sees you doing. Screenshot based but never stores them.

https://donethat.ai/data

The same tech stack is pretty easily adaptable to openclaw tracking. If anybody would like to try, DM

Also looking into AI based security tools for monitoring security of DoneThat. Thinking of using zeropath would love to hear if people tried them / have other suggestions

Totally understand that. I’m trying everything I can to make it as secure and private as possible, see https://donethat.ai/data but can never be 100% of course. At the /compare link I list some open source tools that try to do something similar fully local.

A Substack for 80/20 life advice that gets repeated every year. We all know what to do, the idea of this is to remind us every week of one aspect of life and what best practices are for that area.

https://euzoia.substack.com The concept: https://euzoia.org

Tried to do this as low tech as possible, so website is just an off the shelf notion wrapper

Still an AI time tracker that watches your screen.

Currently experimenting with a proactive agent, Don, that pops up like clippy and also works over email.

A fully automated time-tracker that feeds screenshots into llms to help you spend your time where it matters to you.

https://donethat.ai

With lot's of built-in data privacy safeguards https://donethat.ai/data

Also made an overview of similar tools out there https://donethat.ai/compare

Recently broke on Linux with a Wayland security update, working on a fix! Using Electron for cross-platform.

I am right now building a proactive coach on top of my AI work capture app. Concept is very simple: It takes a screenshot every few minutes and analyzes what you're working on. From there it identifies task blocks, and checks if it should start a chat based on your intentions (eg to tell you to move out of your rabbit hole, take a break, help with a task, ...)

https://donethat.ai Passively processing screenshots is obviously pretty sensitive, it has an option to bring your own (local or remote) LLM, otherwise I process with gemini and never store any data.

It's in beta right now so if you want to try it you have to enable "proactive chat" in settings.

I also made a list of similar tools out there: https://donethat.ai/compare

Been living in Amsterdam and six years in still don't speak Dutch. Maybe this is the moment... How to do you ensure quality in 90 languages? Seems impossible for a one-person-show if even Duolingo is only managing to do pretty basic examples?

An app to track my work automatically by feeding screenshots to LLMs and analyzing those. https://donethat.ai

Obviously this is quite sensitive data so architected it to never store raw data, allow for bring-your-own-key, and even in team settings be fully private by default, everybody keeps control of all their results.

Started about six months ago, have some first users, and always looking for feedback!

On your request 12

> A local screen recording app but it uses local models to create detailed semantic summaries of what I’m doing each day on my computer. This should then be provided as context for a chat app. I want to ask things like “Who did I forget to respond to yesterday?” I've been using Rewind for a year now, and it's nowhere near as useful as it should be.

I am building something like this but unfortunately not local because for most people's machines local LLMs are just not powerful enough or would take too much drain on battery. Work in progress, always curious for feedback! https://donethat.ai

If you want fully local, somebody did a post on HN on something related recently: https://news.ycombinator.com/item?id=45361268
