Khroma uses machine learning to generate custom color palettes based on your preferences. Train the algorithm by selecting colors you like, and it learns to suggest harmonious combinations that match your design sensibility. The tool provides hex codes, RGB values, CSS snippets, and accessibility ratings for each palette.
Vespa is a backend infrastructure platform that combines vector search, text retrieval, and machine learning inference at scale. Built for developers creating search applications, recommendation engines, and retrieval-augmented generation (RAG) systems, it handles billions of documents while maintaining sub-100ms query latency. Powers applications from Spotify and Perplexity to smaller AI-driven projects.
Weaviate is an open-source AI database that combines vector search, retrieval-augmented generation (RAG), and agentic capabilities. It provides billion-scale vector storage with hybrid search, built-in embeddings, and natural language query processing. Developers can deploy on managed cloud, self-hosted infrastructure, or multi-tenant Shared Cloud.
Tweeter is a Chrome extension that uses AI to help you compose tweets, threads, and direct messages. Set your tone and topic, and let the extension generate content tailored to your style. It works directly on Twitter and TweetDeck, making content creation seamless within your workflow.
Avanty is a Chrome extension that brings AI assistance into Metabase, letting data analysts generate and refine SQL queries using natural language instead of manual coding. Describe what you need in plain English, and the extension creates or modifies your SQL accordingly. It also explains complex queries, formats code automatically, and suggests descriptive titles for saved analyses.
Viinyx AI is a Chromium extension that adds an AI chatbox, writing assistant, and prompt toolbar to websites. It connects with numerous language and image models, works with pages and uploaded documents, and keeps sensitive settings and conversations in the browser. It suits researchers, writers, marketers, and other people who want AI available throughout their online workflow.
Algolia is a search-as-a-service platform that uses AI to power discovery experiences in web and mobile apps. It provides real-time search, personalized recommendations, and AI agents that help users find what they need instantly. Built for developers with easy integration and enterprise-grade scale.
Qdrant is a vector database engine that enables semantic search for AI applications by storing and retrieving data based on vector embeddings rather than keywords. It supports hybrid search combining dense vectors with sparse matching, advanced filtering, and result reranking. Purpose-built for retrieval-augmented generation (RAG), recommendation systems, and knowledge-based AI features.
Nous Research creates open source language models and agent frameworks for developers. The Hermes model family provides production-grade inference via Nous Portal API with flexible free and paid tiers. Hermes Agent is a self-improving autonomous agent framework with persistent memory, runnable on any infrastructure from a single VPS to GPU clusters.
Linxa is a Chrome extension that automates LinkedIn lead generation and outreach. It analyzes your website to understand your ideal customer profile, identifies warm prospects using LinkedIn signals, and drafts personalized messages—all within LinkedIn. Designed for agencies, consultants, and SaaS founders who want qualified leads without switching tools.
OpenScience is an open-source AI-powered platform that automates the research process—from literature review through hypothesis generation, code execution, and experiment running. It integrates with scientific databases like UniProt and PubChem, and supports models from Anthropic, OpenAI, Google, and others. Researchers can define a research goal and let the system autonomously conduct investigations and summarize findings.
IntelliMail is a Chrome extension that uses AI to automatically generate email responses, eliminating the need to write emails from scratch. The extension integrates directly into your browser and promises to handle email composition while maintaining strict privacy — the tool explicitly states it does not read or store user data. Perfect for professionals who spend hours drafting routine messages and want to reclaim time.
