# I Will Build Your AI App, Web App or SaaS Solution

You have an idea, a process to automate, or a product to launch — and you need engineers who can actually build it with AI at its core. Zinn Digital is a London-based team of 75+ engineers specialising in [AI-powered mobile](https://zinnhub.com/zinns/develop-ai-chatbot-mobile-app-ai-website-and-ai-agent-development-llm/), web, and SaaS development. Whether you want to integrate a language model into an existing app or build a brand-new AI product from scratch, this service covers the full development cycle.

Every engagement is structured around milestones, so you review and approve each stage before we move forward. You stay in control throughout, and nothing is handed over until you are satisfied.

\*\*What We Can Build\*\*
 Our engineers work across a wide range of AI application categories, including: text-to-image generators, face and body swapping tools, travel planners, biography writers, recipe planners, AI chatbots built with LangChain, fitness generators, AI transcription tools, and ERP planners. If your use case is not listed, get in touch — we are experienced in training open-source models to meet custom requirements.

\*\*Services Covered\*\*
 – AI model integration and custom model training
 – Mobile app development
 – Web app and SaaS development
 – Back-end development
 – App deployment across AWS, Azure, GCP, and DigitalOcean
 – Post-development maintenance and support

\*\*Source Code & Ownership\*\*
 All source code is maintained in a private GitHub repository throughout development and transferred to you in full once the project is complete and all milestones are settled. You own everything.

\*\*Confidentiality\*\*
 Your project details are kept strictly confidential. We do not share information between clients, and we are happy to sign an NDA where required.

\*\*Why Zinn Digital?\*\*
 We provide regular progress updates, are highly flexible across time zones, offer free consultations before you commit, and write clean, efficient, well-structured code. Our end-to-end approach means you have a single accountable team from requirement gathering through to deployment.
