HelpHub – GPT chatbot for any site
Hi HN, I’m the founder of a SaaS platform called CommandBar (YC S20). We’ve been mucking around with AI-related side quests for a while, but recently got excited enough about one to test it with some customers. Results were surprisingly good so we decided to launch it. HelpHub is AI chat + semantic search for any website or web app. You can add source content in 3 ways: -Crawling any public site via a URL (e.g. your marketing site or blog) -Syncing with a CMS (like Zendesk or Intercom) -Add content manually The chatbot is then “trained” on that content and will answer question’s based on…
In plain words
HelpHub is an AI chatbot and semantic search tool that websites and web apps can embed to answer user questions. It learns from content added through web crawling, CMS integrations like Zendesk or Intercom, or manual uploads, then responds based solely on that trained content. The embeddable widget provides both a chat interface for questions and a search interface for browsing source material. It is designed for any website or web application needing customer-facing AI assistance.

Hi HN, I’m the founder of a SaaS platform called CommandBar (YC S20). We’ve been mucking around with AI-related side quests for a while, but recently got excited enough about one to test it with some customers. Results were surprisingly good so we decided to launch it. HelpHub is AI chat + semantic search for any website or web app. You can add source content in 3 ways: -Crawling any public site via a URL (e.g. your marketing site or blog) -Syncing with a CMS (like Zendesk or Intercom) -Add content manually The chatbot is then “trained” on that content and will answer question’s based on that content only, not referencing directly the knowledge. The output is an embeddable widget the contains two things: the chatbot interface for user’s to ask questions, and a search interface for users to search through the content the bot is trained on directly (as well as view source content). You can play around with a demo on some popular sites here: https://helphub.commandbar.com Some features we added that make it better IMO than just chat: -Suggested questions (based on the page the user is on and their chat history) -Suggested follow-up questions in a chat response -Ask a question about a specific doc -Recommend content based on who the user is and where they are Would love to hear feedback (not lost on me that there are other chatgpt-for-your-site products and we are probably missing a ton of functionality from there) and can also share details about how we built this. It’s not rocket science but does feel magic :) -James

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
