Composer

Brand-voiced AI content generation for marketing teams

Composer is an AI content-generation tool under your brand for marketing teams. It is built around the assumption that the LLM is a good first-draft engine and a terrible final-draft tool — so the product is a brand-voice configurator, a template library, a human review workflow, and per-asset cost / quality reporting, not a chat box where you re-type "make this more punchy" eighteen times. It runs on the AI-Native SaaS Stack so the LLM gateway, RAG over brand assets, and per-tenant billing rollups are first-class.

Key features

  • Brand-voice configurator (tone, vocabulary, banned words, must-include rules)
  • Template library (blog post, ad copy, email, social post, product description)
  • RAG over brand-private knowledge (product docs, past content, style guide)
  • Multi-LLM gateway (Claude default, OpenAI fallback, swappable per tenant)
  • Human review workflow with diff view, suggested edits, and approve / publish
  • Bulk-generate with CSV import (e.g., 200 product descriptions in one batch)
  • Per-asset cost tracking (LLM calls, retrieval calls) with per-tenant rollup
  • Plagiarism / fact-check optional layer (Originality.ai integration)

What you get

Composer launches as a multi-tenant SaaS under your brand. The brand-voice configurator is calibrated during onboarding from a sample of the customer’s existing approved content. RAG indexes are built over the customer’s product docs and style guide. The first batch of generated assets goes through human review before any auto-publishing.

Sample customer story (placeholder — illustrative only)

A 12-person D2C kitchen-goods brand licensed Composer to scale up the product-description authoring that had bottlenecked their merchandising calendar. Within ninety days they had pushed 1,400 product descriptions through a generate-and-review pipeline that took 14% of the time the previous human-only process required, with brand-voice consistency rated higher in customer surveys (the human writers had drifted in voice over six years).

What’s NOT included

  • Image / video generation. Composer is text-only.
  • Auto-publish without human review. Available as a paid Pass-2 customization, but the default workflow gates every asset on a human approve.
  • A purpose-built AI helpdesk. Use Agentdesk (chatbot) or Copilot Helpdesk (in-inbox AI assist).
  • Vector training on customer’s full corpus for fine-tuning. RAG is in; fine-tuning is a paid engagement.
