Show HN: TextAI – Native SMS AI assistant for individual and group chats https://bit.ly/3WA41yf

Show HN: TextAI – Native SMS AI assistant for individual and group chats Hey HN community! Like many of you, I spend most of my day in text conversations. One day I found myself switching between group chats and various AI apps, and thought, why can't AI just live where we already chat? So I built TextAI. It's an AI that works right in your SMS app. No new app to download, no platform to learn. Just text +15626840069 to start chatting or add it to any group chat! The tech and stack details: - Native SMS/MMS integration with context management across conversations - Handles multiple participants, learns group preferences, and scales for concurrent chats - Able to converse in multiple languages - Built with Twilio on top of a foundational LLM model, plus building my own domain logic on top Some cool things people have used it for: - A group of my friends used it to plan a weekend trip to Las Vegas last week. It was their first time there. They used it to get suggestions on the must-do activities, casinos to play at, and finding restaurants that worked for vegetarians and meat lovers. - A high school student showed the power of AI and started a group chat with their grandpa! - my personal fav - A couple who used it to find new hiking trails around where they live without arguing for their preferences I built this because I believe AI should be accessible through existing communication channels, not locked in new apps. It should be accessible to all, and frankly, it's important to keep things simple. Hope you find it useful, and I would love your feedback, the good and the bad! Thank you for reading! https://bit.ly/4gbBAOd January 23, 2025 at 11:23PM

Show HN: Chat with multiple LLMs: o1-high-effort, Sonnet 3.5, GPT-4o, and more https://bit.ly/4gjqSFy

Show HN: Chat with multiple LLMs: o1-high-effort, Sonnet 3.5, GPT-4o, and more Hello HN! I was fed up switching between multiple UIs to ask GPT, Claude, etc… the same question and comparing the answers. So I built a way to ask multiple models the same question efficiently by having the LLM compare the responses and only show you new and valuable information from the 2nd model. This way you still get a fast response as normal from the 1st model, but also get any added value provided by the 2nd model. Initially I built my own UI to use this, but stumbled upon Open WebUI (formerly Ollama WebUI) which is fantastic, but is made more for local access to LLMs. So I talked to its creator, Timothy Baek, and he mentioned that security needed to be shored up before production deployment. I did some scans with semgrep, and fixed some XSRF and CORS issues along with making sure the JWT tokens, passwords, etc… were secure. This was in addition to other folks' amazing security contributions. So now we build on Open WebUI! oss ftw After launching privately a month or so ago and posting a few reddit links, I have about 100 users. We also just got access to the o1 API and provide o1-high, medium, and low effort. o1 high effort is able to solve coding problems that only o1 pro can also solve, though pro can go further and has better formatting, o1 high effort is a nice option if you don't want to fork over $200/mo. https://bit.ly/4h6Srmy... You can use o1 for free in PolyChat, which is the only place I've seen you can do so. You can also ask multiple models the same question and stream the answers simultaneously side by side. https://bit.ly/4h7DZun And you can have multiple chats going simultaneously and they will continue in the background and notify you when they're done. Another cool feature that makes long chats way easier to navigate is the overview (three dots on top right of chat) https://bit.ly/4gaxNAz We give you full control, unlike most providers, to change the system prompt, temperature, etc.. in the chat settings in the "Controls" on the top right. The formatting for code outputs and inputs is fantastic, using codemirror, and you can run code in the code blocks if it's python or JS using in-browser runtimes. You can also share chats within polychat where other logged in users can see them: e.g. https://bit.ly/3CcoNNE Or you can share it publicly to the OpenWeb UI community https://bit.ly/3E6tM2S... Finally we allow you to search and organize your chats into folders which makes finding things super fast! Infra: My custom backend that combines models and does things Open WebUI doesn't handle like token tracking is written in FastAPI and uses LiteLLM for easily accessing different model APIs. I host everything on GCP using Cloud Run for the backend and use PostGres for Open WebUI's db, along with BigQuery and Firestore for my FastAPI app's db. Pricing: Our pricing makes it cheap to access top models. It's free at first, then we offer subscription tiers starting at $5/mo which allots about ~1 million tokens per month, enough for most people. But unlike Claude's UI for example, we don't shut you down with rate limits, but rather let heavy users upgrade beyond to $10, $20, $40, $80, etc... We also suggest a plan based on how quickly you used your free tokens, so you have an idea upfront of the monthly cost before you buy. And you can upgrade or downgrade at any time. Thanks Show HN <3 https://polychat.co January 21, 2025 at 08:40PM

Show HN: I built an active community of trans people online https://bit.ly/3PKV8hp

Show HN: I built an active community of trans people online A year ago I surveyed the internet and noticed there was only one popular space for trans and gender-non-conforming people to meet; Lex. Lex is not well liked by its users. Its software feels heavy and it is full of cash grabs and anti-patterns. It was recently acquired and is sure to only become more hostile to its users as it turns towards profit generation. With this in mind I built t4t, an alternative specially designed for not only queer people, but specifically trans people. It is an extremely lightweight service. I built it with my most ideal stack: Flutter, Svelte, Supabase, Posthog. It has grown in the last year to about 4,000 monthly active users. I think it could grow way beyond that this year. https://bit.ly/3PLhZcL January 23, 2025 at 06:07AM

Show HN: I made a simple agentic framework in JavaScript https://bit.ly/3EgE8wZ

Show HN: I made a simple agentic framework in JavaScript Well, I wouldn't call it a framework, but rather an easy way to define tools and agents, allowing the agent to think and do the work. - Currently supports Open AI, and DeepSeek models. I tried building an HN title recommender agent with this framework that analyzes top-performing posts on HN and suggests titles for HN posts. And this was the agent's reply after inspecting 10 best posts: Having analyzed the top 10 performing posts on Hacker News, we've observed that successful titles are often concise, intriguing, and sometimes provocative or impactful. They tend to evoke curiosity, highlight significant issues, or reveal unexpected information. Based on these insights and considering the unique nature of your GitHub repo, which introduces an agentic framework in JavaScript, here's a suggested title and message for your Hacker News post: Title: 'EnvoyJS: A New Frontier in JavaScript - Introducing Agentic Frameworks' Lol :P Still a lot of work to do! https://bit.ly/4g4HikU January 22, 2025 at 10:18PM

Show HN: NotepadJs – A cross-platform love letter to Notepad As a native Windows user who switched to macOS a few years back, one thing I never got over was the simplicity and usefulness of the old school Notepad app. This app aims to recreate that very same experience, cross-platform and easily installable as a PWA. I've been using this for personal use for around 2 years and I figured it was time to share it with the world. Criticism, issues and PRs are welcome.

Show HN: Habby – A straightforward bullet journal with habit tracking https://bit.ly/4g3iOZn

Show HN: Habby – A straightforward bullet journal with habit tracking Heya HN, I started journaling about a year ago and recently landed in my perfect setup, a simple sentence to remember each day, combined with a flexible habit tracker. Over the holidays I turned this approach into a free expo app that I want to share. Basically, you get: - One sentence per day, enough to remember each day. - Flexible habit tracking (still working on finding the best UX here) - No backend, no tracking, all in device (just sentry for errors) - Clean, minimal interface - Export your data - Stats to track your progress I built this primarily for my own use, but I'd love to hear what the HN community thinks about it. Android is still in closed testing, but will be available soon. Thanks! https://bit.ly/4hm1YG0 January 22, 2025 at 10:27AM

Show HN: Ergonomically call LLM in bulk from CLI https://bit.ly/42gfabg

Show HN: Ergonomically call LLM in bulk from CLI Hi! I've found myself repeatedly writing little scripts to do bulk calls to LLMs for various tasks. For example, run some analysis on a large list of records. There are a few "gotchas" to doing this. For example, some service providers have rate limits, and some models will not reliably return JSON (if you're asking for it). So, I've written a command for this. What I've tried to do here is let the user break up prompts and configuration as they see fit. For example, you can have a prompt file which includes the API key, rate limit, settings, etc. all together, or break these up into multiple files, or keep some parts local, or override parameters. This solves the problem of sharing settings between activities, and keeping prompts in simple, committable files of narrow scope. I hope this can be of use to someone. Thanks for reading. https://bit.ly/4hoDjAM January 20, 2025 at 11:22PM

Show HN: Terraform Provider for Inexpensive Switches https://bit.ly/4jqI26W

Show HN: Terraform Provider for Inexpensive Switches Hi HN, I’ve been building this provider for (web managed) network switches manufactured by HRUI. These switches often used in SMBs, home labs, and by budget-conscious enthusiasts. Many HRUI switches are also rebranded and sold under various OEM/ODM names (eg. Horaco, XikeStor, keepLiNK, Sodola, etc) making them accessible/popular but often overlooked in the world of infrastructure automation. The provider is in pre-release, and I’m looking for owners of these switches to test it and share feedback. My goal is to make it easier to automate its config using Terraform/OpenTofu :) You can use this provider to configure VLANs, port settings, trunk/link aggregation etc. I built this provider to address the lack of automation tools for budget-friendly hardware. It leverage goquery and has an internal SDK sitting between the Terraform resources and the switch Web UI. If you have one of these switches, I’d love for you to give it a try and let me know how it works for you! Terraform Registry: https://bit.ly/4jC5fmL OpenTofu Provider: https://bit.ly/4hiPsHi I’m happy to answer any questions about the provider or the hardware it supports. Feedback, bug reports, and ideas for improvement are more than welcome! https://bit.ly/4hpLdKh January 18, 2025 at 02:14PM
