Masthead gives luxury publishers an on-site assistant that composes citable dossiers from the publication's own writing — built, operated, and calibrated for each tenant.
See a dossier composedA live instance, composing against a demo archive of thirty-odd articles across travel, watches, fashion, design, and hospitality. Each dossier is generated in real time. Every claim you read below is drawn from a specific article we've indexed.
The demo composes against a deliberately cross-vertical archive so any reasonable query returns a result. A production tenant composes against its own archive only; depth replaces breadth.
Masthead draws only from articles you've published. Every sentence in every dossier is citable back to a specific piece in your catalogue. There is no open-web retrieval, no hallucinated restaurant, no invented watchmaker. If it wasn't in your archive, it isn't in the dossier.
Before launch, your editor reviews twenty representative compositions and we tune prompts, vocabulary, and structural preferences against the notes. Calibration continues monthly thereafter. A reader cannot tell a Masthead dossier apart from a short piece written by your staff — and that's the point.
Every dossier closes with commerce cards — restaurants, hotels, watches, pieces, tickets — routed through your existing affiliate partners. Revenue flows to you, not through us. We earn against the build and against revenue share or a flat fee, at your choice. No take-rate at the click layer.
Each tenant is a first-class instance with its own database schema isolation (Postgres row-level security), its own theme, its own prompt calibration, and its own commerce tables. Masthead is a multi-tenant platform in the operational sense; your readers see only your brand, and your archive is never retrieved by another tenant's queries.
Composition runs on Anthropic's most capable model (currently Claude Opus 4.7). Classification and reranking run on a faster, smaller model. Every dossier persists its token count and resolved cost so per-tenant economics are transparent. Typical dossiers compose in three to six seconds and cost low single-digit cents at list Anthropic pricing.
You point a subdomain — typically concierge.yourpublication.com — at our infrastructure via CNAME. We deploy on Vercel in the region closest to your readers, ingest your archive from a WordPress export (other CMSes on request), and hand you an admin URL for editorial review. No engineering work on your side beyond DNS.
We import your archive once at onboarding and schedule a weekly re-sync thereafter. New articles appear in retrieval within twenty-four hours of publication. Embeddings re-run on any article you edit. Corrections propagate; dossiers cite current canonical text.
Build fee covers architecture, prompt calibration, archive ingestion, theme, commerce integration, and six weeks of post-launch tuning. Pricing is shown as a starting point; specifics negotiated per tenant.
We read every inquiry and reply the same day. No forms.
