Stay calmsy
with Chalmsy.

Not even slightly. Chalmsy was built on one principle: simplicity above all else. No jargon, no steep learning curve, no IT department required. If you can send an email or fill in a form, you already have every skill you need.

Chalmsy grew up inside a creative studio, so it's especially fluent in visual, client-facing, quoted work — but it's built for any business that runs on clients, bookings, proposals and invoices: consultants, planners, photographers, caterers, agencies, trades, and beyond. Those four jobs — quote, book, deliver, invoice — are universal. Chalmsy does all four, wearing your brand and speaking in your voice. There's a dedicated tour for florists, event planners, venues, interior designers, consultancies and trades.

Everything Chalmsy produces — proposals, invoices, client-facing documents, the interface itself — is dressed in your brand: your colours, your logo, your style. It's not a template with your name dropped in. Think of it as a tailored suit, not a uniform.

No. Most people start by sending one proposal through Chalmsy and leave everything else where it is. Your client list and bookkeeping history import from a CSV whenever you're ready — including part-way through a year.

That's the specific thing it's built not to do. Chalmsy uses proposals you've already sent as the reference for tone, so drafts come back sounding like you. You review and edit every one before it goes anywhere near a client.

It works invisibly — no prompts to write, nothing technical to set up. Point it at a handful of proposals or invoices you've already sent, and it reads your style, your tone, your pricing, then quietly matches them in everything it drafts from there on.

Yes. Team members can be given a role that hides margins, costs and the books, while still letting them work on bookings and details.

No — it runs in the browser on any device. If you'd like it to behave like a proper desktop app, with its own window and icon, you can install it in two clicks. Here's how.

You, and whoever you invite. Every business's data is isolated at the database level, not just hidden in the interface. More on how that works.

No — your business is not training material. Our Terms state plainly that we do not use your content to train AI models, and work sent to the model travels through Anthropic's commercial API, whose terms commit that submissions aren't used for training either. Your proposals teach Chalmsy how you write; they don't teach anyone's model how to write. What the AI reads — and what it never does.

That's what the Atelier tier is for. Beyond the platform itself, the Chalmsy team can build a fully custom setup — tailored workflows, branded document systems, a configuration fitted to the particular rhythms of your business. See Atelier.
