What People Are Saying

  • "Using Claude Code with Superpowers is so much more productive and the features it builds are so much more correct than with stock Claude Code."blog post

  • "The brainstorming skill is great. It helps flesh out a rough early idea, and it uses subagents to adversarially review its own spec/plan."HN comment

  • "I personally don't like superpowers very much; I think Claude makes more mistakes when using it than when not."HN comment

  • "I don't think too much structure here is going to be desired by all users; the plan often ends up being code blocks in a Markdown doc."HN comment

  • "It forces Claude through a 5-phase discipline that eliminates the just-start-coding failure mode that wastes tokens."blog review

  • "I feel better about tradeoffs being made and much more confident that the code does what I want."blog post

UI-TARS AI Agent: This IS THE BEST AI Agent EVER & BEATS Claude's Computer Use!

Market Signal

Why It Has Market Pull

UI-TARS-desktop is ByteDance's open-source, vision-language computer-use agent that controls a desktop or browser purely from screenshots via natural language. It has rapidly become one of the most-starred projects in the GUI-agent space, and its underlying model posts state-of-the-art benchmark results that outperform OpenAI's Operator and Anthropic's Claude on several computer-use tasks.

  • Roughly 36,600 GitHub stars and ~3,700 forks, with 38 releases shipped (latest v0.3.0, Nov 2025)
  • The UI-TARS model reports 47.5 on OSWorld and 73.3 on AndroidWorld, beating GPT-4o, OpenAI Operator, and Claude 3.7 on those tasks
  • Backed by ByteDance and released under a permissive Apache license, with open weights published on Hugging Face in 7B and 72B sizes
  • Positioned as an open alternative to Anthropic's Computer Use and OpenAI Operator, with coverage in VentureBeat and other outlets
  • End-to-end vision-language model that drives a screen from raw screenshots only, with MCP integration for tool-augmented workflows

feedbacks

What People Are Saying

  • "ByteDance's UI-TARS can take over your computer, outperforms GPT-4o and Claude."VentureBeat article

  • "It's also Apache licensed."HN comment

  • "The screenshot shows the click position correctly, but the actual operation does not execute at the intended location."GitHub issue

  • "The model identifies an option correctly but uses wrong coordinates every time it attempts to click."GitHub issue

  • "It still requires substantial computational resources, particularly for large-scale tasks."vendor docs

  • "It may occasionally generate inaccurate descriptions, misidentify GUI elements, or take suboptimal actions."vendor docs

INSANE Photorealism with Z Image Turbo + 2-Step Upscale

Market Signal

Why It Has Market Pull

Z Image Turbo is Alibaba Tongyi Lab's open-weight text-to-image model that became one of the most downloaded models on Hugging Face within days of release, prized for producing photorealistic, bilingual-text images in under three seconds on consumer GPUs. The hosted demo surfaces it as an MCP-callable tool, making it usable directly inside agentic content pipelines.

  • Topped Hugging Face trending on launch day with 500,000+ downloads and ranks first among open-source text-to-image models on the AI Arena Elo leaderboard
  • The hosted demo is tagged as an MCP server, holds ~3,400 likes, and has spawned 100+ derivative Spaces plus 737 adapters
  • Generates a 1024x1024 image in about 2.3 seconds on an RTX 4090 and runs in as little as 6-8GB of VRAM when quantized
  • Active multi-platform discussion across Hacker News threads, dozens of ComfyUI and YouTube tutorials, and 1,200+ community reviews

What People Are Saying

  • "It punches far above its weight class."HN comment

  • "The prompt adherence is impressive for a 6B parameter model."HN comment

  • "It's fast, about 3 seconds on my RTX 4090."HN comment

  • "Z-Image got popular because people with 12GB cards could still use it, and potentially train on it."HN comment

  • "Works better as a refiner downstream of a bigger model, and still runs faster than Flux2."Reddit r/StableDiffusion

  • "Z-Image Turbo has gotten a lot of hype, but it's worse at some specific text-rendering tasks."HN comment

Goldfish

589

Most AI tools make you explain the context before they can help. Goldfish already has it. It privately remembers what you’ve been working on across your Mac, then helps you write better from any app. Press Option in a text field to draft replies, summarize threads, rewrite sentences, or recall important details from your recent work without copying, pasting, or re-explaining the whole backstory.

Invoko

414

Invoko is an AI desktop helper you can talk to while you work. Bring it beside anything on your screen, ask it questions, or let it handle tasks across your apps.

MakersClaw

399

Hire AI employees that run 24/7 in their own container with their own memory. One-click into your Slack, Telegram, or Teams. Pre-built for support, sales, research, SEO, or anything you write yourself. Pay per call for the tools they use.

PeakRoutine

243

PeakRoutine connects your sleep, sunlight, exercise, calories, nutrition, mood, hydration, and more — correlates them against each other — then tells you exactly what it means for your body. No generic plans. Just a proactive AI coach that learns your biology and builds habits around it.

Edgee Turbo Models

189

Run state-of-the-art open-source models (GLM 5.1, Kimi K2.7 Code, MiniMax M2.7, and more) in Claude Code at up to 4× the speed (up to 200 tok/s) for a flat $29/month. Set up in minutes, no code changes.

Zoona AI

183

Sluggish, bloated, legacy support tools are dead. Zoona is support for modern teams — it learns from your docs and past conversations, then resolves 60%+ of tickets the second they land. No backlog. No burnout. No endless hiring to keep up. When it does need a human, it hands off with full context so the customer never repeats themselves. This is support that scales with you, not against you. Train it, go live, done.

I am building a map of people who lived in the Roman Empire

210 pts

Driving home from work one day, I wanted to know how many people we knew the names of who lived during the Roman era. Searching around, I found lists of Consuls and officials, but nothing that covered ordinary people or even most people like freedmen and slaves. So I ended up building a pipeline to process the more than 500k Latin inscriptions in the Epigraphic Database Clauss-Slaby https://edcs.hist.uzh.ch/en/ and extract the names of people (and attempt to cluster them, but this is a work in p...

Trace – Offline Mac meeting transcripts you can flag mid-call

202 pts

I'm the developer of Trace, a non-intrusive, shortcut-driven Mac app that records and transcribes your meetings on-device. I know, another meeting transcription app. Please bear with me though, I'm confident that this is at least a little novel. I primarily built Trace for myself. I'd been using MacWhisper, but there was enough fiddling before each call that I'd forget to start it and walk out of an hour-long meeting with nothing written down. So the things I cared about most were that it's quic... (202 points, 83 comments).

On-device transcriber that's 97% accurate at identifying speakers

32 pts

I’ve spent the last seven months building a tool I wish I’d had in my previous roles. MimicScribe is a macOS menu bar app that fits the "AI notetaker" category. It has accurate on-device speaker identification (a first possibly?), real-time meeting talking points for discovery calls, and a fully keyboard- and voice-driven interface. I believe the accuracy of the speaker ID system is its biggest strength. I used fluid audio’s port of ( https://github.com/fluidInference/FluidAudio ) Pyannote's com... (32 points, 10 comments).

Ito – Code reviews that run code

10 pts

I'm Evan and I made Ito.ai It's code review that actually runs your code. The result is that it finds more bugs with a smaller false positive rate. You get screenshots, videos, and run logs. I built Ito because manual verification sucks and I thought I could automate it. I've been a professional developer for 15 years and now more than ever, I'm just spending time making sure things work. I looked into all of the other agentic testing tools that click around a url you give them and frankly, they... (10 points, 8 comments).

git-lrc – Free, Micro AI Code Reviews That Run on Git Commit

8 pts

Hi HN, I'm the author of git-lrc, would appreciate some feedback from the community Last year my team started using AI coding tools more heavily, and we found ourselves generating tons of code, but spending less time looking at the stuff that's been generated. We felt like we were losing a bit of grip/understanding of what we were building. Regressions occasionally slipped through. Sometimes changes made it all the way to production only to be reverted later. We tried several AI code review tool... (8 points, 0 comments).

Macro – unified system for email, chat, tasks, docs, agents (AGPL/Rust)

8 pts

Hey HN! We're launching Macro (macro.com) — an open source, AI-native system that unifies email, chat, tasks, calls, docs, and CRM in one interface with shared memory. Before Macro, we ran our startup on Superhuman + Slack + Notion + HubSpot + Linear. Each of these apps are good but they don't talk to each other, they're proprietary and closed off. We wanted one unified system, open source, with shared memory, that we could build our company around. Macro is built to be modular and fast. It's de... (8 points, 1 comments).
