Build small business apps with an AI coworker
Small businesses often have tiny apps they need and zero reason to hire a full engineering team: a quote calculator, client portal, invoice tracker, intake form, KPI dashboard, approval queue. Duet builds the app and runs it from the same workspace, so the tool does not become another thing you have to operate.
How Duet runs this with review rules.
Describe the job the app should do
Tell Duet the workflow in plain English: who uses it, what they enter, what happens next, and what systems it should touch. The app starts from the business process, not from a framework choice.
Connect the data sources
Duet can connect spreadsheets, CRMs, payment tools, calendars, databases, files, or APIs through available integrations, credentials, or scoped setup. If the first version can run on a spreadsheet, Duet starts there instead of overbuilding.
Generate the first working version
Duet builds the UI, database, permissions, and workflow logic, then gives you a live URL. You test it with real data instead of reading a spec for two weeks.
Iterate with the people who will use it
Ask for changes in the same chat: add a filter, rename a field, export CSV, make the mobile view less cramped, send an email when status changes. Duet ships the edits and remembers why they were made.
Host and monitor the app
The app runs from your Duet workspace with logs, files, memory, scheduled jobs, and integrations nearby. Build and run stay together, which is the difference between a demo and a business tool.
Turn repeated work into automation
Once the app is stable, Duet adds the cron, webhook, approval step, or report that lets it run on schedule under your rules. The app becomes a coworker-operated workflow, not another dashboard to babysit.

- Small Businesses
AI for Shopify store owners
You're running a Shopify store and a customer service desk and a marketing team — alone. Duet plugs into your store, your inbox, and your ad accounts to help run the loop: product page copy, support replies, abandoned-cart sequences, and the analytics report you've been meaning to look at since launch.
- Small Businesses
AI for service business owners
You run a salon, a clinic, a contracting crew, a cleaning business. The phone never stops, the inbox is a mess by Friday, and half your leads never get a follow-up. Duet sits on top of your existing tools — Google Calendar, QuickBooks, Jobber, your phone forwarding — and runs the front office while you're on a job site.
Common questions about handing this off.
Is Duet a no-code app builder?
Not exactly. No-code builders give you blocks to assemble. Duet gives you an AI coworker with a workspace, filesystem, memory, code execution, and integrations. You describe the business job and it builds the tool.
What kinds of apps are best for Duet?
Internal tools, client portals, calculators, dashboards, intake forms, approval queues, reporting apps, lightweight CRMs, and workflow tools are ideal. Duet is not trying to replace a full product engineering team for complex consumer software.
Can non-technical users make changes?
Yes. You ask in plain English and Duet edits the app. Technical users can inspect code and logs, but small business owners do not need to learn a builder interface to change a field or ship a new flow.
Where are the apps hosted?
Apps are hosted from the Duet workspace on a Duet subdomain or custom domain. The same workspace that built the app can run scheduled jobs, manage files, and connect to the tools the app needs.
Can Duet maintain the app after launch?
Yes. That is the point. Duet can monitor logs, fix copy, add fields, update integrations, generate reports, and keep the app aligned with the workflow as your business changes.
How is this different from hiring a developer for a small tool?
A developer can build the first version, but then every change becomes a ticket. Duet builds the first version and keeps operating beside it, so small improvements happen when the business asks for them.
