Show HN: RateMyPrompt – share and rate prompts with auto AI evals https://ift.tt/XYcqDj4

Show HN: RateMyPrompt – share and rate prompts with auto AI evals Couldn't find a reliable, free place to share & rate AI prompts so I thought I'd take a stab at it Already has 500+ prompts generated by AI using the latest model prompting guidelines 5 different supported prompt types: full prompt, enhancement, template, system, chain 20+ categories: coding, writing, marketing, business, creative, etc. Every prompt gets evaluated automatically by multiple AI models (Claude 3 + GPT-4 Mini, more to come) Then humans can rate and there is an overall score that takes both AI & humans into account AI eval prompt here: https://ift.tt/eiOZrpB I'm still quite the noob when it comes to AI stuff so I'd love feedback about RateMyPrompt and ways that it could be improved https://ift.tt/qU0Dc2o July 19, 2025 at 01:05AM

Show HN: I built library management app for those who outgrew spreadsheets https://ift.tt/AcmYRza

Show HN: I built library management app for those who outgrew spreadsheets I've been working on librari.io for the past several months and just launched the beta version. The Problem: I have 500+ books across multiple rooms in my house and was desperately looking for an app to manage them properly. Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use. What I Built: - Multiple libraries: manage collections in different locations - Location tracking - remember exactly which shelf each book is on - Loan management - track books you've lent to friends - Custom fields & tags - store any additional book info the way YOU think about them - Reading progress tracking - dates, duration, personal ratings - Modern UI/UX - clean & actually enjoyable to use Current Status: - Beta version live - Working on improving the responsiveness of the app and addressing initial user feedback Would love feedback! Especially curious about: - What features would make YOU actually use a library management app? - UI/UX feedback always welcome - Any book collectors here who'd be interested in beta testing? Looking forward to your thoughts! Thank you in advance. https://www.librari.io/ July 19, 2025 at 12:58AM

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG https://ift.tt/lLyJvWi

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG For folks working on Graph RAG and trying to get LLMs to generate Cypher queries, I ran some experiments on the LDBC dataset and wrote a blog post about it (code is available in the link shown at the end of the post). I've been trying to answer a burning question of mine that I've had for a while now: when doing Text2Cypher, are LLMs better at interpreting graph schemas in JSON, XML or YAML? (Spoiler alert, the format barely matters, it's all to do with context engineering and retaining only the relevant parts of the graph schema in the prompt). Results on the latest LLMs are really good! The post also contains some other tips on graph schema design: I think we're in an age now where we need to design graph schema for both LLMs and humans. If you're working on Text2Cypher in any way, hope some of these ideas and experiments are useful! https://ift.tt/jJkObVm July 18, 2025 at 07:22PM
