Why Café 1842

A real business makes the product question concrete.

Café & Conditorei 1842 is a historic Zürich café and confectionery with a highly visual live site, house-made patisserie, cakes, events, changing seasonal hours, reservations, German content, and a social mission through Stiftung Arbeitskette.

Design position

Still Café 1842.
Now easier to run.

Harriet should preserve the café’s burgundy identity, historic interiors, patisserie photography, German voice, events, and reservation flow. The owner experiences a capable colleague—not a replacement brand or a technical dashboard.

01

Speak like an owner

Terrace notices, event dates, photos and menus—not commits, builds and branches.

02

Show, then explain

A visual result comes before implementation details or technical logs.

03

Nothing goes live alone

Harriet prepares. The owner previews and explicitly publishes.

04

Every action is reversible

Plain-language history makes restoration feel safe and ordinary.

The golden path

From a passing thought to a safe live change.

Current site → Harriet

Start with what the owner already recognizes.

The left screen is the live Café 1842 website captured while creating this concept. The right screen imagines the Harriet handoff using the same domain, visual identity, photography, and German voice.

The goal is not to erase the existing brand. It is to make that brand easier for its owner to operate.
00 · The handoff

Their identity, already inside.

The first screen uses Café 1842’s real logo, photography, domain, and German copy. The owner should recognize the business before learning anything about Harriet.

!This assumes Harriet invitations are sent only after an AI-generated migration has passed human review.

Natural language website request
01 · Ask naturally

“From October, we close at 19:30.”

A seasonal-hours update becomes a simple German sentence. Harriet finds every relevant location, changes it consistently, and prepares a branded preview.

1Voice is visually first-class because owners are likely to use Harriet while moving between daily tasks.
02 · Work visibly

Confidence without a terminal.

Owners see outcome-oriented steps: what Harriet found, changed and checked. They can leave the app and return when the preview is ready.

2Progress is intentionally honest but non-technical. Exact time promises should only appear when the backend can support them reliably.

03 · Review & publish

Actual brand. Explicit decision.

The preview combines the proposed notice with Café 1842’s real interior photography and identity. The owner sees the customer-facing result before deliberately publishing.

3“Nothing is live until you approve it” should become a repeated product promise, not fine print.
04 · Remember & improve

Café history, not Git history.

Seasonal hours, corporate gifts, patisserie galleries, and menu updates become understandable business history.

4Proactive suggestions can demonstrate recurring value, but they never publish themselves.

Trust architecture

The interface reflects the operating model.

Harriet’s technical differentiators—isolated agents, Git history, customer-owned hosting and portable source—become understandable customer promises.

H

Private worker

Each customer’s agent and website run in an isolated workspace.

Approval gate

Production changes require a deliberate action from an authorized owner.

Full history

Every change is stored and an earlier revision can be restored.

Always yours

Source and hosting belong to the customer and survive Harriet.

MVP information architecture

Three places, one job.

Avoid the temptation to mirror every backend object. The first app can remain extremely small.

02RequestsConversations, active work, previews and decisions awaiting the owner.
03HistoryPublished revisions, previews and restoration controls.

What this concept should test

The screens are a hypothesis, not a specification.

01

Will owners trust a conversational request without seeing technical details?

02

Is a visual preview plus plain-language summary enough confidence to publish?

03

Do voice and quick requests reduce anxiety for people unfamiliar with AI?

04

Does website health create recurring value beyond occasional content updates?

05

Can customers understand revision restoration without Git vocabulary?

06

Which fixed interface terms need different phrasing in Bulgarian and German?
