Lets AI agents learn a specific person's writing style from their own samples and rewrite AI-generated drafts in that voice before anyone reads them. Runs locally with a stored voice profile shared across agents, adding redaction, retrieval-based exemplars, and a deterministic check that flags introduced phrases, dropped numbers, broken links, and stray placeholders for review.

Provides a catalog of curated author writing styles and tools to blend or analyze them across eight dimensions for text and image prompt generation. It enables users to apply structured literary patterns through deterministic style modeling and coordinate-based interpolation.

Allows AI assistants to measure your writing style across 45 attributes, create a voice profile from your samples, generate drafts matching that voice, and score any text for voice consistency.

Enables agents to rewrite drafts in your own voice, adapted to the occasion and channel, by learning your style from samples you wrote and from feedback on what you actually send. Supports multiple "Hands" per account with tools for creating, updating, and inspecting learned rules, style cards, and usage.
