Tome is a cloud-native SaaS application built around a generative AI engine (leveraging large language models, likely OpenAI GPT) to produce structured narrative content from user prompts. The platform supports rich embeds including Figma frames, Loom videos, live data tiles, and 3D models via a tile-based layout system. It offers a web app with real-time multiplayer collaboration powered by a CRDT-style sync layer. While a public REST API is not broadly advertised, Tome integrates with third-party tools and supports shareable public links with analytics.
