It connects to tools like Linear, Notion, Slack, Google Drive and Confluence, and offers premium models on its paid tiers. Free to start, with a Pro plan at $15/mo billed annually.

Turns laws and regulations into AI compliance agents.

Norm Ai converts laws, regulations and internal policies into AI agents that embed compliance checks directly into business workflows — reviewing AI-generated content, communications, agreements and filings against the rules that apply. Built on its Legal Engineering Automation Platform (Leap), lawyers and former regulators encode complex requirements into operational AI systems. It targets 'compliant by design' automation for regulated enterprises in finance and beyond.

AI agents that handle complex customer support in regulated industries.

Gradient Labs builds AI agents that resolve customer support and operations queries — disputes, KYC, lending and account questions — for banks, fintechs and other regulated businesses. Its agents learn a company's own products and procedures so they can handle nuanced cases end-to-end rather than deflecting to a human. Founded by early Monzo employees, it focuses on the accuracy and safety needed for high-stakes financial conversations.

AI that reads medical documents and automates patient referrals.

Tennr is a healthcare operations platform that uses purpose-built language models to read inbound documents — referrals, faxes and insurance forms — extract the relevant data, and route patients through intake, authorization and care coordination. It targets the referral process, where patients commonly get lost between providers, automating the manual paperwork that bogs down clinics and provider groups. The New York-based company processes millions of healthcare documents every month.

Build, run, and monitor AI phone agents that hold real conversations at scale.

Enterprise voice-AI platform for automating high-volume inbound and outbound phone calls. Bland runs the full stack — language model, speech-to-text, text-to-speech, and telephony — on its own infrastructure, with conversational pathways, voice cloning, and webhook integrations. Positioned for regulated industries with SOC 2, HIPAA, and PCI compliance.

Generate and control production-grade images with purpose-built models.

AI image and video generation platform aimed at creators and studios, built on Leonardo's own foundational models (Phoenix, Lucid Origin). Offers fine-grained control — ControlNet-style guidance, reusable 'Elements', a real-time canvas, and image-to-motion — for game art, concept work, and marketing visuals.

Persistent, local knowledge graph for AI tools — stored as plain Markdown.

An MCP server that gives AI assistants a durable, local knowledge base built from your conversations, notes, and documents. Everything is written to standard Markdown files you own, indexed by a local SQLite store, and readable/editable in Obsidian. Connects to Claude, Cursor, VS Code, and other MCP-compatible clients.

Long-term memory SDK that lets agents learn and adapt over time.

A memory toolkit for AI agents that extracts and stores facts from conversations and refines agent behavior through prompt updates. Exposes semantic, episodic, and procedural memory via a storage-agnostic core API plus tools agents can call during or after a conversation.

Summarize YouTube, search, and any page with ChatGPT — free and ad-free.

Open-source browser extension that adds AI summaries and translation across the web: YouTube videos, Google/Bing results, PDFs, emails, and arbitrary pages. Works free and ad-free out of the box, with an option to bring your own model key for heavier use.

Managed RAG-as-a-service with built-in hallucination control.

Vectara is an enterprise GenAI platform that delivers retrieval-augmented generation as a managed service, bundling ingestion, embedding, retrieval, reranking, and grounded generation behind one API. It ships first-party retrieval and generation models and a built-in hallucination-evaluation model (HHEM) to measure and reduce ungrounded answers. It targets regulated, accuracy-critical applications and AI agents.

AI studio to record, edit, and produce podcasts and video.

Async is a browser-based creative studio for recording, editing, and producing podcasts and video, with studio-quality remote recording, text-based editing, AI enhancement, and multilingual dubbing. Its Revoice feature clones a voice from a short sample to fix mistakes without re-recording, and a developer Voice API exposes its 1,000+ AI voices. It was known as Podcastle until a 2026 rebrand.

AI-native vector search for multimodal product discovery.

Marqo is an end-to-end vector search engine that generates, stores, and retrieves embeddings for text and image data through a single API, so teams don't have to stitch together a separate embedding pipeline. It has since repositioned around AI-native ecommerce search, merchandising, and recommendations, with turnkey integrations for major commerce platforms.

Enterprise-grade LLMs, embeddings, and retrieval built for private deployment.

Cohere builds large language models for the enterprise rather than the consumer. Its Command models cover agentic, multimodal, and multilingual generation; Embed and Rerank power high-quality search and retrieval; Aya is a multilingual research family spanning 70+ languages; and North is a workplace AI platform built on top. Cohere's emphasis is data control — models can run in a private VPC, on-premises, or via a managed Model Vault.

No-code platform for AI voice agents that automate phone calls.

Synthflow is an enterprise voice-AI platform for building and deploying AI agents that handle phone calls — inbound and outbound — without code. A visual flow designer, in-house telephony, real-time monitoring, and 200+ integrations across calendars, CRMs, and telephony let teams stand up agents for customer service, appointment scheduling, and lead qualification. It runs on a pay-as-you-go model: build and test free, then pay per call once live.

Open-weight generative models for image, video, audio, and 3D.

Stability AI is the company behind Stable Diffusion and a family of open and proprietary generative models spanning image (Stable Diffusion, Stable Image), video (Stable Video), audio (Stable Audio), and 3D. Its models can be self-hosted under Stability's licensing, called through the Platform API, or used in the DreamStudio web app, giving builders an open alternative to closed image-generation endpoints.

Security and governance gateway for enterprise AI use.

WitnessAI is a unified security and governance platform for how an organization uses AI. It sits as a gateway over employee and AI-agent interactions, giving security teams three things: observability into all AI activity (including shadow AI), policy enforcement and governance, and protection against prompt injection, data leakage, and other model-layer threats. Each customer runs in an isolated, single-tenant environment encrypted with their own keys.

Open-source framework and cloud for realtime voice, video, and physical AI agents.

LiveKit is the realtime infrastructure layer most voice-AI stacks are built on. Its open-source Agents framework wires together streaming speech-to-text, an LLM, and text-to-speech with reliable turn detection, interruption handling, and telephony, so agents can join a session and converse in near real time. You bring your own STT, LLM, and TTS providers; LiveKit handles the low-latency WebRTC transport. It runs self-hosted under Apache 2.0 or as a managed cloud platform.

Open-source AI coding agent for VS Code, JetBrains, and the CLI.
