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. A visual canvas lets designers, PMs, and developers collaborate on conversation logic, connect a knowledge base for RAG, and deploy to web widgets, phone, or any channel via API. 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.

Expressive property data APIs for building proptech.

RealEstateAPI (REAPI) is a developer-focused property data platform offering APIs for property search, detail, comparables, parcel boundaries, address autocomplete, and skip tracing across roughly 95% of U.S. properties. It targets proptech startups and data-heavy products that want flexible, modern access to nationwide real estate data, and provides lender-grade automated valuations with confidence scoring for pre-qualification, underwriting, and portfolio monitoring.

Nationwide property data API powered by AI-collected public records.

Realie is a property data platform that serves nationwide parcel, ownership, mortgage, and zoning data through a fast API. AI agents continuously collect records from public sources across 3,100+ U.S. counties in all 50 states, normalize the differing county layouts, and verify them so the data stays current. It handles search, lookups, and enrichment at sub-10ms latency, offers an automated valuation model and comparables, and supports full-state or nationwide bulk delivery via Amazon S3.

Enterprise visual AI trained only on licensed data, with IP indemnification.

A visual generative AI platform for enterprises that generates and edits images and video while keeping output commercially safe. Its models are trained exclusively on licensed data from Getty Images, Alamy, and Envato, and generations come with IP indemnification. A "Visual Generative Language" lets developers control lighting, camera, composition, and objects with structured parameters rather than free-text prompts, delivered via API, cloud, BYOC, or on-prem.

Turns your technical docs into a RAG assistant that answers users' questions.

A platform that ingests a company's technical documentation and 30+ other sources (GitHub, forums, Slack, Discord, Zendesk) and turns them into an AI assistant that answers complex product questions with citations. Built for external end users, where accuracy matters most, it flags low-confidence answers and surfaces unanswered questions so teams can close documentation gaps. Deploys as a docs widget, chat integration, or API.

Citation-based literature mapping that visualizes how papers connect.

A literature-discovery tool for researchers that maps the scholarly landscape instead of returning flat result lists. Start from one or more "seed" papers and it surfaces related work, citing/cited papers, and relevant authors as an interactive network — drawing on 270M+ papers — so connections appear even when articles don't cite each other directly. Collections sync to Zotero and can trigger new-paper alerts.

No-code website translation that drops into any CMS via one snippet.

A website localization platform that translates a site into multiple languages without a developer or localization team. It integrates with Shopify, WordPress, Webflow, Squarespace, Wix, and custom builds through a single snippet, auto-detects new and updated content to translate, and handles multilingual SEO (hreflang, translated URLs). Combines neural machine translation with optional brand-tuned custom AI models and a manual-editing layer.

AI presentation maker whose smart templates auto-design every slide as you add content.

A web-based presentation tool that pairs generative AI with a library of "smart" templates: type a prompt and DesignerBot drafts a full deck, then each Smart Slide auto-adjusts its layout, spacing, and alignment as you add or remove content so the design stays consistent without manual fiddling. Includes PowerPoint import/export, brand controls for teams, and viewer analytics on shared decks.

AI YouTube summarizer that turns any video into key takeaways and timestamps.
