About

NarrativAI is built for writers with original characters, long-running universes, and casts too big to hold in their head. Two things make it different from a generic AI writing assistant. The OC Vault is a continuity engine that builds itself passively as you write - reading your drafts and extracting facts about your characters, world, and timeline without you maintaining a separate document. When something you write contradicts an established fact, it catches the drift before it compounds across chapters. Muse, the co-writer, never operates as a black box. It always shows which state it's in - Listening, Suggesting, or Drafting, so you always know exactly what it did to your universe and why. Two more states (Safety Checking and Resting) are on the way as the product progresses. Currently we're offering a Founding Member offer for the first 100 people who join: lifetime Premium access, a 50,000 credit package, a permanent badge, and a rate that's locked in for good.

About

TK is a cloud-based writing workspace from Medium for writers, journalers, and people developing ideas through writing. Its editor supports notes and drafts, with an inline @TK assistant for research, retrieving earlier writing, and editorial or headline feedback. Prompts and shared libraries help users develop ideas and exchange drafts for discussion. TK can turn notes and research into wiki-style knowledge bases linked to a writer’s accumulated material. Users can import Medium writing, Bear or Obsidian vaults, and Markdown files, then export notes or an archive as Markdown. Android and iOS apps and mobile widgets support voice or text capture; an MCP server and Claude skill let compatible AI agents access TK content. TK supports journaling, research, long-form drafting, feedback, and preparing work for publication on Medium. TK is cloud-hosted and has no native desktop app.
