Show HN: Ledgi: UK net worth tracker with a CLI for AI agents

nelson687 — Fri, 06 Mar 2026 12:22:16 +0000

I built Ledgi because I wanted to track my net worth across UK-specific stuff: ISAs, pensions, property, investments, debt.

Most finance trackers are US focused or want you to connect your bank. Ledgi is manual entry only, with AES field level encryption on all financial data.

There's also an open source CLI and a Claude Code skill. You authenticate with scoped API keys (accounts:read,holdings:write, etc.) and an AI agent can query your data directly. I use it to ask things like "what's my net worth breakdown?" or "how much ISA allowance do I have left?"

CLI: https://github.com/LedgiApp/ledgi-cli

Claude skill: https://github.com/LedgiApp/skills

happy to hear your feedback!

Show HN: I built Cuiz-AI, turns documents into quizzes in seconds

nelson687 — Fri, 31 Oct 2025 12:05:47 +0000

I built Cuiz-AI to generate practice quizzes from PDFs, Word docs, and PowerPoints using AI.

The name is a play on "Quiz" + "Cuis", a small rodent from Argentina, where I'm from. That's why the logo is a little rodent.

The tricky part: Getting an LLM to generate quality quizzes fast was quite hard. I spent a lot of time testing different models and approaches to get the generation time down from minutes to seconds.

You upload a document, the LLM reads it and generates multiple choice questions with explanations. It also tracks your quiz history and progress.

Would love feedback, especially on use cases I might not have thought of and in the quality of the questions!

thank you!

That's a great suggestion! thanks for having a look. I just updated the landing page with some examples :D

Show HN: I built a tool that generates quizzes from documents using LLMs

nelson687 — Sat, 29 Mar 2025 12:12:29 +0000

Hey everyone! I recently built this little side project that takes any document you upload and turns it into practice quizzes using LLMs to generate the questions: https://www.cuiz-ai.com

Being a backend engineer, I have always struggled to finish my side projects due to my awful frontend skills. Now, with the progress of AI coding tools, I had no more excuses. 100% of the frontend, landing page and even the logo was made using a combination of Cursor, ChatGPT and Claude, but it's always been under my supervision and never blindly accepted the proposed changes. The backend and infra was handled by myself.

The tool itself is pretty straightforward: upload any PDF/DOC, get quiz questions generated by an LLM, export them if you want, and come back to your previous quizzes anytime. I got this idea when I was studying from a pdf for my UK citizenship. I know there are similar tools around, but it was a good opportunity for me to build something end to end!

I'd love to know what you think or what you might use this for. Any feedback is super appreciated!

Top past week and Top last month have the exact same content, guess it's because the content in the site is new?

Is this an online course?

There are plenty of options and ideas out there to work on your spare time to improve the world and its society. It's just a matter of thinking which areas you feel you could have had something better and you didn't. In my case, me and 2 friends realised that when we were younger and students, we had a lot of questions and ideas but we didn't have a place where we could discuss or people with experience to get advise from (we are from latinoamerica). Today, as we are the people with experience, we created a mentorship platform for latin-americans, where people like we were before, can join and ask for advise and learn from more experienced people. This is our way to try to improve the world. site: https://oraculi.io
