Describe what you want to build. Deotter helps you make it.

Tell Deotter what you need — an app for your customers or an internal tool for your team. AI writes the code, you steer, change things, and run the result.

you

Flag invoices as overdue after 14 days instead of 30.

deotter changes the code

lib/overdue.ts

- const OVERDUE_AFTER_DAYS = 30;+ const OVERDUE_AFTER_DAYS = 14;  const isOverdue =    daysSince(due) > OVERDUE_AFTER_DAYS;

you run it

  • Apps and internal tools. Start from a plain-language description. Get a working interface you can open and use.

  • Code you can change. Deotter generates real code and edits it with you. Nothing is locked away.

  • AI agents for development tasks. Hand routine work to agents and review what they change.

  • Reusable workflows. Set up the steps you repeat once. Use them again in the next project.

  • Connected tools and data. Wire in the tools and data your application needs.

Building is only half the job.

Once you have something to sell, Deotter helps you decide who to reach, find relevant leads, run LinkedIn and email outreach, and see which campaigns bring useful conversations.

  • Define your customer. Describe who the product is for. Deotter turns that into a working customer profile.

  • Find and score leads. Discover matching companies, filter the list, and rank every lead by fit.

  • LinkedIn and email outreach. Reach people where they already are, with AI-assisted research and messaging.

  • See what works. Campaign and pipeline analysis shows which outreach turns into real conversations.

Build and grow in the same place.

Everything on this page happens inside one product. Build something, put it in front of the people who may need it, and let their answers shape what you build next.

  1. Idea

    You know a problem worth solving.

  2. Working software

    Build it with AI in Deotter.

  3. Target customers

    Define who needs it. Find them.

  4. Outreach

    Contact them on LinkedIn and email.

  5. Feedback

    See which conversations go somewhere.

  6. Better product

    Take what you learned back into the builder.

Made for small teams that build things.

founder

A founder describes their MVP, gets a working first version, then builds a list of the first companies to contact — and emails them from the same place.

agency

An agency ships a client application, then researches similar prospects who need the same thing and runs outreach to win the next project.

internal team

A team replaces a spreadsheet with an internal tool and sets up reusable workflows to automate the work around it.

consultancy

An AI consultancy turns one-off engagements into reusable applications instead of rebuilding everything from scratch each time.

What happens after you book a demo

  1. You book a time

    The Book a demo button opens a calendar — pick a slot that suits you. Email works too: hello@deotter.one.

  2. We walk through the real product

    A short call on your use case: the building workspace and the sales tools, live. Not slides.

  3. You decide

    If it fits, you get access on a subscription, with AI credits covering the AI-heavy work. Then you start building.

The interfaces on this page are product mockups — you will see the real thing on the call.
