Working on cross-flock discovery in sanctum [1] so I can cut a 1.0 release hopefully before Christmas.

I am always looking for more people to test and play with it or even review the code. We've got a nice little user community going.

Usually this comments drowns in the crowd of the massive amount of awesome stuff people are building, but if you find sanctum useful, hit me up. Good things are happening.

Stay happy

An AI-powered social media management tool that creates, schedules, and publishes content automatically across Twitter/X, LinkedIn, Facebook, Instagram, and Threads.

https://postsam.ai

*The problem:* As a solo founder, I was spending hours each week on social media - writing posts, scheduling them, managing multiple accounts. I wanted something that could handle the entire workflow automatically while still letting me stay in control.

*What PostSam does:* - AI generates content tailored to your brand voice (you provide initial brand info) - Creates full content campaigns with posting schedules - Calendar interface to review, edit, or reschedule posts before they go live - Auto-publishes to all connected accounts - Learns from your edits to improve future content

*Current status:* Live and working. Seeing good engagement rates from users who set it up once and let it run. The AI content quality has been surprisingly good - it adapts well to different brand voices.

All those have official API for creating posts? If not, there is a chance they will ban the tool.

Spent the last three months building a competitor/lookalike ML model + API. Started using plain embedding similarity and quickly realized you end up with similar noisy results as ocean.io. Ended up using similarity learning which works quite well with little data. Launched this as an API and small web app. Hardest part right now is to fend off scrapers honestly.

Examples:

- YC: https://markets.apistemic.com/companies/y-combinator-goaq9

- uber: https://markets.apistemic.com/companies/uber-com-ojj2j

- Anthropic: https://markets.apistemic.com/companies/anthropicresearch-yx...

Try it for any company here: https://markets.apistemic.com

Chipping away at trying to bring a total reform of American English.

https://reformeuropa.net/raea.html

Currently its at like 90% completion but there are some subtleties that probably need to be worked out a bit more. The PDF linked from that page explains all the details (although for reading just peeking at the charts on Page 4, 5, & 7 should get someone to reading it fine enough). Currently both Alice In Wonderland and Dr Jekyll are fully transcribed into the reform if someone wants to jump into seeing it in action. Certainly interested in thoughts and complaints of the system.

Also looking here sometime soon to playing around with an improved SI unit system. So if anyone has any new ideas here too I'd be very interested.

Examples of things to be touched upon would be like: - Make g (not kg) the base mass unit. Making 1 m^3 of water = 1 g - Bring commas to be the universal decimal point separator.

Historical public companies Merton Probabilities of Default.

A project just for fun and still having to finish a couple of things.

I plan to make the datasets public (everything but some raw market data as vendors don't allow that) and also about to add the explanation of what Merton PD is.

I’m working on a platform to run a friendly competition in “who builds the best reasoning AI Agent”.

Each participating team (got 300 signups so far) will get a set of text tasks and a set of simulated APIs to solve them.

For instance the task (a typical chatbot task) could say something like: “Schedule 30m knowledge exchange next week between the most experienced Python expert in the company and 3-5 people that are most interested in learning it “

AI agent will have to solve through this by using a set of simulated APIs and playing a bit of calendar Tetris (in this case - Calendar API, Email API, SkillWill API).

Since API instances are simulated and isolated (per team per task), it becomes fairly easy to automatically check correctness of each solution and rank different agents in a global leaderboard.

Code of agents stays external, but participants fill and submit brief questionnaires about their architectures.

By benchmarking different agentic implementations on the same tasks - we get to see patterns in performance, accuracy and costs of various architectures.

Codebase of the platform is written mostly in golang (to support thousands of concurrent simulations). I’m using coding agents (Claude Code and Codex) for exploration and easy coding tasks, but the core has still to be handcrafted.

Ooooh, neat, I had a similar idea, like an AI olympics that could be live streamed where they have to do several multi-stepped tasks

We developed a novel optimization pipeline for LLMs so large models can run on a standard laptop.

Our first prototype optimized an 80B model to run at full 256k context at 40 tokens/s while only taking up 14gb of RAM.

We are currently leveraging this tech to build https://cortex.build a terminal AI coding assistant.

I've spent several years since Covid times solo-developing an ad-free website with 50+ solitaire/puzzle games.

I've gathered some feedback from users from HN already and now trying to fix things.

I'm looking to genuinely improve the experience so would be incredibly grateful for any feedback. I'm also wondering what it lacks – any particular games or modes?

I’m building DB Pro, a modern database workbench that makes working with Postgres, SQLite, and MySQL fast and intuitive.

I’m documenting the journey in monthly devlogs.

Here’s the first devlog: https://youtu.be/cSY-C8oiUU8

You can check it out here. We're very close to launching a v1: https://dbpro.app
