The dataset is designed to train generative AI foundation models for protein and enzyme design, powering drug discovery, industrial biology and planetary-health applications that public databases can't reach.

Describe a game in plain language and play it — no-code, prompt-to-game.

A browser-based platform that turns natural-language descriptions into playable 2D and 3D games. Instead of writing scripts you describe scenes, rules and behaviors, and Rosebud generates the code, art and mechanics with real-time previews and instant deployment. It pairs AI-generated visuals with templates and curated assets, and lets creators publish, share and monetize what they build.

AI agent for Unreal Engine — generate C++, Blueprints and 3D from prompts.

An AI toolkit that embeds directly inside Unreal Engine 5 to accelerate game development. From natural-language prompts it generates and explains C++ code, builds and analyzes Blueprints, produces textured 3D models, and answers context-aware questions about Unreal concepts. An agent mode can chain these into multi-step changes across a project.

AI vocal remover and stem splitter for pro-grade audio separation.

An AI service that separates a mixed track into clean stems — vocals, instrumental, drums, bass, guitars, piano, synth, strings and wind — for remixing, karaoke, sampling and production. Beyond separation it offers noise and echo removal, voice cleaning, and voice changing. It runs in the browser and as desktop and mobile apps, with a minute-based credit model.

Page-aware AI agent in your browser — summarize, automate, extract.

A browser extension that turns any web page into a workspace for a multi-model AI agent. It reads the page you're on to summarize articles, YouTube videos and PDFs, draft and reply to email, proofread, generate content, and scrape or monitor sites. A library of prebuilt commands plus visual automation lets it click, fill forms and export results, and it connects to Zapier, Make and n8n for longer workflows.

Unified API gateway that extracts structured JSON from images, video, and documents.

VLM Run is a developer platform for visual AI that returns reliable structured JSON from images, video, and documents through a single API, combining hyper-specialized vision-language models with computer-vision tools for tasks like document parsing, structured OCR, object detection, and segmentation. It offers fine-tuning to specialize models for a domain, dashboards, and flexible deployment. The platform is operated by Autonomi AI.

Framework and browser platform for building reliable AI web agents.

Notte is a full-stack platform for building and running AI web agents: it turns any website into a structured action API so agents can click, fill forms, and navigate flows instead of scraping raw text. It offers managed cloud browser sessions, serverless browser functions, credential vaults, proxies, CAPTCHA handling, session replays, and observability, with compatibility for Playwright, Puppeteer, Selenium, and CDP tooling. A source-available framework on GitHub underpins the hosted platform.

Free Chrome extension that runs an AI agent to complete tasks across any website.

HoloTab is a browser extension from H Company that deploys a computer-use AI agent inside Chrome: describe a task in natural language and it navigates sites, clicks, fills forms, and makes decisions like a person would, without technical setup. A Routines feature lets you record a task once and re-run or schedule it later. It is aimed at everyday users rather than developers.

AI platform that designs new materials on demand, like a search engine for molecules.

CuspAI is a materials-discovery company building an AI platform that takes a target set of properties and generates viable, synthesizable material candidates, with carbon capture and other sustainability applications as early focuses. It combines generative AI foundation models, deep learning, and molecular simulation into one loop to shortcut conventional trial-and-error discovery. It is engaged as an enterprise platform and research partner rather than a self-serve product.

AI medical scribe that turns the consultation into structured clinical notes.

Heidi is an AI scribe for clinicians that listens to a consultation and drafts structured notes, referral letters, and patient handouts in real time, with customizable templates and support for 100+ languages. It pairs the Scribe with Evidence (clinical lookup), Remote (a wearable capture mode), and Comms for follow-up. A free tier covers unlimited basic consults, while paid tiers add EHR push and team features.

Speaker intelligence — diarization that tells who spoke when.

pyannoteAI turns conversational audio into speaker-attributed transcripts: it identifies speakers, separates overlapping voices, and provides speaker metadata. Built on the widely used open-source pyannote.audio library, it adds a premium REST API and Python SDK with higher accuracy and near real-time speed.

Emotionally intelligent voice AI — speech-to-speech (EVI) and expressive TTS (Octave).

Hume builds voice AI tuned to emotional expression. Its Empathic Voice Interface (EVI) is a speech-to-speech system that reads vocal tone, handles interruptions and back-channeling, and can front any external LLM. Octave is its expressive text-to-speech model with voice design, cloning, and modulation.

A generative, ultra-fast physics platform for robotics and embodied AI.

An open-source simulation platform for general-purpose robotics and embodied-AI learning, rebuilt from the ground up in pure Python. Combines a unified multi-physics engine, a photorealistic renderer, and a generative data engine that turns natural-language prompts into simulation scenes and training data.

Open-source models, datasets, and tools for real-world robotics in PyTorch.

Hugging Face's robotics stack — pretrained policies (ACT, Diffusion Policy, SmolVLA, Pi0), shared datasets, simulation environments, and designs for low-cost manipulator kits. Aims to be the 'Transformers for robotics', lowering the barrier to training and sharing robot-learning models.
