Custom AI App Development: Drawing Tutorial
See how InApps delivered Artixo a custom AI drawing tutorial app for Android tablets, owning full scope with zero scope creep.
Custom AI Drawing Tutorial App
Artixo needed a vendor who could own the full scope of a custom build without scope creep or budget surprises, a common failure point in fixed-price app development.
InApps designed and delivered a custom AI drawing tutorial app, built natively for Artixo's proprietary Android tablets, with a generative AI feature that turns a single reference image into a step-by-step drawing guide.
Project goals
- Generate AI-powered, step-by-step drawing tutorials from user images
- Lock scope and budget upfront, with no mid-project surprises
- Support multiple user roles within the tutorial experience
- Deliver a feature stable enough to justify contract renewal
- Build natively for proprietary Android tablet hardware
Client requirements
Across each key area, these requirements shaped every product and delivery decision we made.
Hardware Integration
The app had to run natively on Android hardware
- Native integration with proprietary Android tablets
- Performance optimized for the specific hardware profile
- Stable behavior across firmware updates
- No reliance on generic third-party device assumptions
AI Drawing Feature
The core value of the product was an AI capability competitors didn't have.
- Generate drawing tutorials from a single reference image
- Step-by-step visual guidance, not static instructions
- Output quality consistent enough for real learners to follow
Multi-Role Access
Different users needed different levels of access within the same app.
- Role-based permission system for video content
- Clear separation between learner and admin/teacher roles
- Secure access control per role
- Scalable structure for future role types
Scope & Budget Control
As a Project-Based engagement, Artixo needed certainty above all else.
- Requirements locked and documented before development began
- No mid-project scope changes without explicit agreement
- Transparent reporting against the original budget
- A deliverable that matched the original brief, with no surprises
Business challenges
The core obstacles that shaped how we scoped and delivered this product.
Hardware Constraint
The drawing tutorials had to run natively on proprietary Android tablets, ruling out generic off-the-shelf solutions.
Generative Complexity
Generating accurate, step-by-step AI drawing guides from a single reference image required custom model integration, not template logic.
Scope Risk
As a custom-development engagement, any ambiguity in requirements risked scope creep and budget overruns, exactly what Artixo wanted to avoid.
Fixed-Price Pressure
A Project-Based model meant the deliverable had to be scoped and locked precisely from day one, with no room for renegotiation later.
Our solutions
Each solution kept the project on scope, on budget, and on schedule.
Fixed-Scope Delivery
Locked requirements upfront and delivered against a clearly defined scope, with no budget surprises.
Multi-Role Video Permissions
The platform included a video lesson library requiring role-based access so learners and admin/teacher accounts saw different content.
