I've been studying wine and was a bit frustrated with the wine note taking apps around, so I've been building one. It allows to:

- Scan wine labels (it analyzes the label automatically)

- Add structured or unstructured tasting notes

- Create lists (shared or not) to keep wines organized

- View information about the regions/grapes

It's called Cork Club: https://corkclub.app/

Create video game sprites and animations via prompts.

Pretty excited because I've started to get high volume, repeat customers.

Ahhh this is exactly what I'm looking for! I don't see any pricing on any pages. Would love to know how much this costs (I don't know what 455 diamonds is worth) as there's a few sprites that I'd love to animate and use in my app.

Not a fan of signing up before seeing how much I'd have to pay. The examples look great though.

1 diamond = 1 cent

Prices are about to drop dramatically. Many of the models dropped >80% in price since initial launch. Any time I have a reduction in cost, I pass the savings directly on to users.

> The animations cost $0.32 ( 32) each.

Not sure if you just added this in or I overlooked it, but exactly the kind of transparency I love. Will give this a try.

EDIT - Did an image generation using the OpenAI 4o model, then ran through the lowest quality animation. This is awesome and first pass is very strong and usable (around 100 diamonds used).

I look forward to seeing prices drop more and the asset pack area fill up. Keep going man, really awesome stuff.

I've tried making game tiles and sprites with Craiyon, which works surprisingly well now. But I always struggle with consistent style, scale, colors. And if I want a border around buttons, it's better if I make it once and apply it myself in photoshop, because the AI will change it slightly every time I ask for a change to the sprite contents.

A RAG Boilerplate with Extensive Documentation

I open-sourced the RAG boilerplate I’ve been using for my own experiments with extensive docs on system design.

And I have bunch of LLM+RAG blogs I post frequently last 2 months : https://mburaksayici.com/blog

It's mostly for educational purposes, but why not make it bigger later on? Repo: https://github.com/mburaksayici/RAG-Boilerplate - Includes propositional + semantic and recursive overlap chunking, hybrid search on Qdrant (BM25 + dense), and optional LLM reranking. - Uses E5 embeddings as the default model for vector representations. - Has a query-enhancer agent built with CrewAI and a Celery-based ingestion flow for document processing. - Uses Redis (hot) + MongoDB (cold) for session handling and restoration. - Runs on FastAPI with a small Gradio UI to test retrieval and chat with the data. - Stack: FastAPI, Qdrant, Redis, MongoDB, Celery, CrewAI, Gradio, HuggingFace models, OpenAI.

For my work I've developed a web-based Monte Carlo simulator with a visual, node-based editor for building supply chain models. Last week, I started making it available for everyone.

You can have a look at https://simcarlo.com. The tool allows you to see the full spectrum of potential outcomes instead of just a single guess.

A kernel extension-less sshfs for macOS. I tried using FSKit and got halfway before I felt too constrained by the extension security model (must be app sandboxed, must be approved by the user in system settings). Now it’s just a standalone command line binary that doesn’t require any special permissions since it proxies NFS to SFTP. Everything “just works” and performance is reasonable

AquiGorka 11/9/2025|

Interesting... the way I workaround'd non-macos-native-sshfs is by using docker and mounting a local folder, do you plan on publishing your tool?

Absolutely: https://github.com/jabedude/sshfs

I built a tool to generate a PDF for each row of a Google sheet. For example, you can generate 100 personalized PDFs (like certificates) for 100 students listed in a Google Sheet.

https://sheetstopdf.com/

Once you sign up and connect your Google sheet, it generates a template (using AI) based on your data, which you can edit in a Notion-like editor. You can then generate PDFs for your entire sheet or a for a range of rows.

Some use cases I'm seeing:

* Certificates for students or course completions

* Monthly invoices for all your clients (https://sheetstopdf.com/use-cases/business/invoices)

* Personalized reports with individual client data

* Event tickets or conference badges

* Contracts, offer letters, or any personalized documents

* Really anything where you have rows of data that need to become individual PDFs

Would love to hear what you think or if you have use cases I haven't thought of yet!

I recently started a local chess club, and did a quick search for software to use to allow us to manage the club, but couldn't find anything open-source/free.

I wanted something that would allow us to record members, games, etc., and also allow us to be assigned a local club rating. Anyway, after doing some searching and only finding paid software, I decided to just build something. That lead to https://openchessclub.org

You can check it out on GitHub: https://github.com/OpenChessClub/openchessclub.

I plan on building a QR code generator that allows club members to check-in during meetings, which will then allow players to be matched, and some other features, although it is primarily aimed at smaller chess clubs, so don't know how far it'll go.

I’ve been working on MemoryPlugin (https://www.memoryplugin.com), a tool that adds long term memory across AI tools

Lately I’ve worked on a chat history based memory feature that can recall information from every conversation you’ve ever had with ChatGPT and Claude. It’s been particularly useful and also technically fun to implement. Speed has been very important as I do just in time summarisation and a multi stage RAG pipeline, and most LLMs have unacceptable performance. I ended up going with GPT-OSS on Groq due to its ultra low latency often completing full generations before Gemini or ChatGPT APIs return even the first token.

The ability to recall details from conversations going back years makes tasks where I want personalised plans or feedback like 10x more useful, at times I get the AI to ingest tens of thousands of tokens of context to help me better.

very surprised I haven't seen this done before - cool idea!

Probably because security nightmare

senotrusov 11/10/2025|

I’ve created a small command-line tool that generates a hash-based, human-readable list of git repositories and data folders. Its purpose is to capture the exact state of all projects and files in a single plain-text file.

I built it because I work across multiple machines and often worry about which projects are on which computer or whether I’ve left any files in unique locations. Now I can diff the summaries between devices to see what’s out of sync, which repositories have uncommitted changes, and which folders have been modified.

I avoid using cloud sync services, and most of my files are already in git anyway. I find that having clear visibility is enough, I just need to know what to commit, push, pull, or sync manually.

I would be glad if it proves useful to someone besides me.
