Turn your text into editable diagrams, infographics, and visuals.

A visual AI for business storytelling that converts written text — prose, outlines, notes — into editable diagrams, flowcharts, mind maps, and infographics in seconds. Generates multiple visual options from a passage, then lets you tweak icons, connectors, colors, and fonts and export to PNG, PDF, or SVG for decks, blogs, and docs.

Pro-grade AI upscaling, denoise, and detail recovery for photo and video.

A suite of AI image- and video-enhancement apps — Topaz Photo, Topaz Video, and Gigapixel — that upscale (up to 16x), denoise, sharpen, deblur, and recover detail using proprietary models that render locally on your GPU. Long the default for photographers, restorers, and post houses, with newer cloud and API options alongside the desktop apps.

Real-time speech-to-text and audio intelligence through a single API.

End-to-end audio infrastructure to record, transcribe, and enrich speech via one API — real-time streaming under ~300ms latency, batch transcription, diarization, translation, and summarization across 100+ languages. Reengineered Whisper for production before shipping its own Solaria models, with EU data residency for compliance-bound teams.

Prompt CMS, evals, and observability for LLM teams.

PromptLayer is a prompt-engineering platform that treats prompts as a content-managed asset: version, edit, and deploy them without touching application code. It pairs that registry with an evaluation harness (datasets, scoring) and an observability stack that logs every request and tracks cost and latency. The collaborative model lets non-technical domain experts iterate on prompts alongside engineers.

Private, on-device audio and video transcription for Mac.

MacWhisper transcribes audio and video files entirely on your Mac — no internet connection and no data leaving the machine. Drop in MP3, WAV, MOV, or MP4 and get a transcript with speaker labels, timestamps, and 50+ export formats. It runs OpenAI's open-source Whisper (and Nvidia's Parakeet) locally, hitting roughly 30x realtime on Apple Silicon via Metal acceleration.

No-code platform to build, launch, and scale AI agents.

Voiceflow is a no-code platform for designing, testing, and shipping chat and voice AI agents for customer support, lead generation, and beyond.

It supports multiple model providers and scales to enterprise call and message volumes.

Open-source platform for the ML and GenAI lifecycle.

MLflow is an open-source platform for managing the full machine-learning and GenAI lifecycle — experiment tracking, model registry, deployment, and, more recently, LLM/agent observability. Its GenAI stack adds OpenTelemetry-based tracing, systematic evaluation with built-in metrics and LLM judges, and prompt versioning. Framework- and provider-agnostic, it runs on your own infrastructure with no vendor lock-in.

A private, AI-organized place to remember everything.

mymind is a personal memory tool: save notes, links, articles, images, and quotes, and it auto-tags and sorts them for you — no folders, no manual filing. AI recognizes what each item is (article, product, recipe, book) and surfaces it again through fast visual, associative search. It's built privacy-first, with no ads, no tracking, and nothing sold or used to train models.

Open-source, local-first workspace for docs, whiteboards, and databases.

AFFiNE is a local-first workspace that combines block-based docs, an infinite whiteboard canvas, and databases — an open-source alternative to Notion and Miro. Pages flip between document and edgeless (canvas) modes, and AFFiNE AI helps draft, summarize, and turn outlines into mind maps and slides. It runs on web, desktop, and mobile, with self-hosting available via Docker.

GPU cloud marketplace for renting AI compute.

Vast.ai is a marketplace for renting GPUs, connecting people who need AI compute with hosts who list spare hardware — from solo owners to Tier-4 data centers. Prices are set by supply and demand, billed per second, and queryable through code. It supports on-demand, interruptible (spot), and reserved instances across tens of thousands of GPUs and dozens of GPU types.

Build native mobile apps by chatting with AI.

Rork turns plain-language prompts into working iOS and Android apps. Its Pro tier generates React Native + Expo projects you can preview live and ship to the App Store and Google Play, while Rork Max builds native SwiftUI apps compiled with Xcode. It focuses on mobile as the target surface rather than web pages, and produces real native apps instead of web wrappers.

Persistent memory layer for AI coding agents.

ByteRover gives coding agents long-term, structured memory that persists across sessions and tools. It organizes project knowledge into hierarchical context trees, stores them locally by default, and serves relevant context back to agents through an MCP server and CLI. It plugs into Cursor, Claude Code, Windsurf, and other assistants, and an optional cloud tier lets teams sync and share context.

AI co-pilot for technical design — diagrams and docs as code.

Eraser is a collaborative whiteboard and docs tool for engineering teams where diagrams are written as code. Its AI generates flowcharts, ERDs, sequence, and cloud-architecture diagrams from a prompt or a pasted code snippet, then lets you refine them in diagram-as-code syntax. It syncs with GitHub and embeds into Notion and Confluence.

AI meeting notetaker that records, transcribes, and clips calls.

Grain records, transcribes, and summarizes video calls and in-person meetings, then surfaces action items and drafts follow-ups. Its signature feature is turning any moment of a transcript into a shareable video clip, with playlists and stories for organizing key calls. It also enriches CRM records and adds deal insights for revenue teams.

AI writing assistant with autocomplete, web research, and citations.

HyperWrite is an AI writing assistant that drafts, rewrites, and autocompletes text across the web, with research and inline citations. It runs as a web app and a Chrome extension, and adds a personal-assistant agent that can carry out multi-step browser tasks. It is built by OthersideAI, one of the first companies to ship a consumer product on GPT-3.

AI-native data platform: warehouse, ETL, BI, and agents in one.

Definite is a data-platform-as-a-service that bundles a managed warehouse, ETL pipelines, modeling, and BI into one AI-native product. Its assistant, Fi, turns natural-language questions into SQL and builds full data apps — filters, KPIs, and tables — not just charts. It ships 500+ connectors and exposes data to external agents like Claude and Cursor over MCP.

AI data-analysis notebooks that turn questions into dashboards.

Fabi.ai is an AI-native analytics platform built around Smartbooks — reactive notebooks that blend SQL, Python, and natural-language querying. Analysts ask a question and Fabi generates the query, chart, or workflow, then turns the result into a shareable dashboard or scheduled report. It connects to warehouses like Snowflake, BigQuery, and Redshift.

Agentic AI assistant for property management and leasing.

EliseAI is an agentic AI platform that automates tenant and prospect communication for property management and multifamily housing. It answers inquiries, schedules tours, processes maintenance requests, and manages follow-ups across voice, SMS, email, and chat so operators can respond instantly around the clock. The same conversational platform has since been extended into healthcare for patient scheduling and non-clinical communication.

AI analyst for commercial real estate underwriting and diligence.

Cadastral is an AI-native, vertically specific platform for commercial real estate, billed as an 'AI analyst out of the box' that works without customer-specific training. It automates complex CRE workflows including T-12 analysis, lease abstraction, loan compliance, acquisitions due diligence, and end-to-end underwriting for real estate, private equity, and private credit teams.
