Show HN: RL Agent that can auto-optimize your LLM prompts Hey everyone! Along with my team, I've developed a reinforcement learning system that automatically optimizes LLM prompts, complete with a visualization feature to track both prompt structure and learning progress over time. Take a look here: https://bit.ly/3YX9Ozo... Check out our website too: https://bit.ly/48Mo9lB In terms of how this visualization works: The RL Prompt Optimizer employs a reinforcement learning framework to iteratively improve prompts used for language model evaluations. At each episode, the agent selects an action to modify the current prompt based on the state representation, which encodes features of the prompt. The agent receives rewards based on a multi-metric evaluation of the model's responses, encouraging the development of prompts that elicit high-quality answers.

Show HN: ZetaJS – client-side LibreOffice widget and automation in the browser https://bit.ly/4fGcPKi

Show HN: ZetaJS – client-side LibreOffice widget and automation in the browser ZetaJS wraps ZetaOffice, a WASM version of LibreOffice - and makes accessing the entire gamut of the LibreOffice programmability interfaces from JavaScript convenient, idiomatic & extremely fast. If you always wanted an entire client-side office suite in the browser, that you could fully automate with JS & seamlessly embed in your web apps - and on top of that, be able to self-host it & keep all data on the client, since there's literally no server involved (except for some static wasm & JS blobs) - then this might be for you. https://bit.ly/4fGskBV November 8, 2024 at 03:43PM

Show HN: Firecrawl-Simple – Stable fork of Firecrawl optimized for self-hosting https://bit.ly/40z3lfu

Show HN: Firecrawl-Simple – Stable fork of Firecrawl optimized for self-hosting Firecrawl Simple is a stripped down and stable version of firecrawl optimized for self-hosting and ease of contribution. The upstream firecrawl repo contains the following blurb: >This repository is in development, and we're still integrating custom modules into the mono repo. It's not fully ready for self-hosted deployment yet, but you can run it locally. Firecrawl's API surface and general functionality were ideal for our Trieve sitesearch product, but we needed a version ready for self-hosting that was easy to contribute to and scale on Kubernetes. Therefore, we decided to fork and begin maintaining a stripped down, stable version. Fire-engine, Firecrawl's solution for anti-bot pages, being closed source is the biggest deal breaker requiring us to maintain this fork. Further, our purposes not requiring the SaaS and AI dependencies also pushes our use-case far enough away from Firecrawl's current mission that it doesn't seem like merging into the upstream is viable at this time. https://bit.ly/3NVAdr9 November 6, 2024 at 12:18AM

Show HN: Open-Source HTTP Interceptor – Capture, Modify, Run Requests in Browser https://bit.ly/3O16XPD

Show HN: Open-Source HTTP Interceptor – Capture, Modify, Run Requests in Browser Hey HN, I recently built an open-source HTTP interceptor called Relay, which works as a Chrome extension for capturing, modifying, and replaying HTTP requests directly in your browser — no account needed. How it works: Relay lets you capture requests as they happen, modify parameters, headers, or body content, and replay them on the fly. You can customize or debug network requests quickly without needing an external tool or complex setup. Key features: - Simple setup: Install the extension and start a session to capture requests. You can filter by URLs and methods. -Request modification: Make quick edits to any part of the requests for debugging or testing. - Copy as cURL: Easily copy requests as cURL commands to use elsewhere if needed. - Replay functionality: Re-run requests with modified data or headers and see the results in your browser. - Local, no account needed: All interactions are handled locally in your browser, so you maintain privacy and control over your data. I built Relay to make tasks like testing API integrations, troubleshooting network calls, and experimenting with client-side requests easier. Originally, I made it for myself because I wanted a faster way to look at and edit network requests without constantly switching between my browser and other tools. After seeing how useful it was, I decided to make it open-source for anyone who would find it useful. Here's the GitHub repo: https://bit.ly/3NW7PFw Would love to hear your feedback and suggestions! https://chromewebstore.google.com/detail/relay-–-intercept-modify/kilmhgoembjiamcmcbecekdonljjiolg November 5, 2024 at 11:48AM

Show HN: CMD+C – Instant Grammar Correction Across All Apps for macOS https://bit.ly/3Cava3H

Show HN: CMD+C – Instant Grammar Correction Across All Apps for macOS Hey HN! Here is my simple native macOS app for correcting grammar — CMD+C. I'm a non-native English speaker working in English-speaking teams, and I care about how my Slack messages and other communications come across. Frustrated with switching between grammar tools, apps that don't support some input boxes, and endless copy-pasting, I built CMD+C — a simple macOS app that corrects grammar on the fly in any app, with just a triple-click. Features: 1) Triple-click "⌘+C" to correct any selected text instantly, no matter where you're typing. 2) Use your own API key (OpenAI, Anthropic) or access premium corrections with our plan. 3) View correction history with explanations from GPT why it was corrected and export JSON/CSV if needed. How it works: 1) Intercept triple "⌘+C" shortcut in macOS 2) Process text with LLM (OpenAI, Anthropic) with custom prompt 3) Replace selected text with the corrected version and save it to better understand why and how it was corrected CMD+C was built in 7 days, is free to use, and I plan to share the source code later this month. I've never built anything before, so I'd love your feedback - let me know what you think! Hope someone finds it useful! https://bit.ly/3YBykF5 November 4, 2024 at 12:03AM

Show HN: I launched a super cheap and simple to use OCR tool for macOS 1. Click capture text 2. Select an area on screen with text 3. Paste the text anywhere Are there other solutions out there? Yes, the best one that I've found is Text Sniper, it $8 so I decided to learn SwiftUI and release Text Capture for $0.99. This one uses MacOS builtin Vision API under the hood so it should also improve with new macOS releases. Would love to hear your feedback! https://bit.ly/3Cb53cF November 3, 2024 at 11:40PM

Show HN: Kis.tools – A directory of tools that work Hey HN! Tired of hitting "Sign up for free" buttons only to discover the real limitations after creating an account? Or finding a "free" tool that adds watermarks to everything? Yeah, me too. I'm building kis.tools, a curated directory of tools that: Work instantly - registration only when technically necessary, have genuine free functionality, keep interfaces clean and focused, process data locally when possible, keep promotional messages or ads minimal and unobtrusive Think of it as a home for tools like Eric Meyer's Color Blender (running since 2003!) - tools that do one thing, do it well, and respect users enough to let them try before asking for anything in return. Every tool is personally tested and described honestly, including limitations. No marketing fluff, just straight talk about what works and what doesn't. Would love your feedback and tool suggestions, especially mobile apps - seems like every 'free' app nowadays sells its core functionality through in-app purchases. https://bit.ly/3CbNxFk November 3, 2024 at 12:17PM

Show HN: An app for biomechanically-optimized exercise selection https://bit.ly/3NON0M7

Show HN: An app for biomechanically-optimized exercise selection I built an app that analyzes individual anatomical variations (limb lengths, joint alignments, mobility patterns) and matches them with biomechanically suitable exercises. The matching algorithm considers: - Valgus/varus alignment - Limb-to-torso ratios - Joint mobility ranges - Anatomical leverages It then cross-references these data points with a curated database of exercises to determine optimal movement patterns for each body type.
