Re: a small order question

draft ready

Hi Maja,

Thanks so much for the kind words about the rye — Soraya bakes that one on Wednesday mornings and I'll pass it along. To answer your question, the seeded loaf you ordered last Tuesday is back on the counter from Friday this week. I've held one with your name on it.

Warmly,
Adelaida · Linnea Bakery

Editorial — Spring 2026

The age of canned macros is closing. Cinder argues for a smaller, warmer, better-cited support surface — one where every reply is drafted by a model that knows your voice and signed by a human who knows your customer. The result is fewer escalations, longer tenure on the support team, and the strange new sound of agents writing again.

What teams
actually ship.

Cinder is opinionated about scope. Four chapters in the support handbook — the rest stays human, by design.

IFirst reply

A letter, not a canned line.

Cinder drafts the first response in your brand voice with the relevant facts already pulled — your agent reads, lightly edits, sends. The customer never knows; they just feel heard.

IISource-of-truth

Citations the agent can stand behind.

Every draft is annotated with the doc, ticket, or commit it pulled from. Two clicks land your agent in the source. Confidence transfers; the customer feels it.

IIITone library

Sound like you. Always.

Train Cinder on your archived replies. The voice that took your team years to find arrives in every draft on day one — warm, specific, never overcooked.

IVMacro retirement

Delete the macros. Keep the warmth.

Cinder makes templates obsolete. Each draft is contextual, signed by a human, and never reads like a form. Macros become a thing you used to maintain.

Letters to
the editor.

Never. Cinder drafts; humans send. We believe the warmth comes from the signature, not the speed. Every draft is reviewed by a person before the customer sees it.

Cinder reads your archive of past replies, marketing emails, and brand guide on a one-time training run. The model is private to your workspace and never shared across customers.

Notion, Help Scout, Intercom, Zendesk, GitHub issues, Linear tickets, and your public help center. Press tier adds private connectors for proprietary internal wikis or knowledge bases.

Per agent per month — the people sending replies. Drafts are unlimited on Studio and Press. There is no per-token, per-conversation, or per-source charge.

Cinder is SOC 2 Type II and ISO 27001. Data residency is honoured at the routing layer (EU, US, SG, AU). Customer messages are never used to train a shared model.
