  note: Product access model, not an API access model — Memoir publishes no API. All three published tiers (Starter $300/mo,
    Scale $1,500/mo, Enterprise custom) route to a "Book a demo" / "Talk to us" Calendly conversation; the only authenticated
    entry point on the site is /login for existing customers. No free tier, no trial, and no self-serve checkout are published.

name: Memoir
description: 'Memoir, operated by Tachyon Labs, Inc., is an AI-powered marketing automation platform in Y Combinator''s Spring
  2026 batch, founded in 2026 by Maanav Agrawal and Jason Zhan. It connects to the systems where product work happens — GitHub,
  Linear and Slack on every plan, plus Jira, Notion, Google Docs, Drive and CRM on higher tiers — and turns shipped product
  updates into multi-channel marketing content: social posts, blog posts, changelogs, launch pages, ads, demo videos and customer
  updates generated in the company''s brand voice and routed through human approval. The product is organized around "Memory"
  (Atlas) for building context about a company and "Motion" (market-motion) for producing and distributing content as teams
  ship features. Published customers include Datost, Smol Machines, TraceRoot and Zatanna. Pricing is published at three tiers
  — Starter $300/mo, Scale $1,500/mo and a custom Enterprise tier — all sold through a demo conversation rather than self-serve
  checkout. Memoir is a marketing SaaS product with no developer program: it exposes only a private session- authenticated
  backend (api.trymemoir.ai answers every path, including /.well-known/*, with HTTP 401 "Not signed in") and publishes no
  public API, developer portal, API reference, machine-readable specification, SDK, CLI or MCP server.'

  detail: 'Memoir ships an end-user marketing SaaS only — there is no developer surface of any kind: www.trymemoir.ai/developers,
    /docs, /api-docs and /llms.txt all return 404 from the Vercel SPA, and the single backend host api.trymemoir.ai answers
    every path, including /openapi.json, /graphql, /mcp and /.well-known/*, with a blanket HTTP 401 {"detail":"Not signed
    in"}.'
