AI-Driven Collaborative Suggestions and Smart Auto-Complete

[bchou9]

Description

Implement an AI copilot that analyzes drawing patterns and context to provide intelligent suggestions, auto-complete strokes, and predict user intent. Similar to GitHub Copilot but for visual drawing, suggesting next shapes, colors, and completing partial drawings.

Current workflow

Users draw without AI assistance; no predictive suggestions or context-aware completions.

Proposed solution

Train or fine-tune a model on canvas stroke sequences to predict likely next actions. Use transformer-based models to understand drawing context and provide real-time suggestions shown as ghost overlays that users can accept or ignore.

Technical requirements

Files to create:

• backend/services/stroke_prediction_service.py
• backend/services/context_analyzer.py
• backend/ml_models/stroke_predictor.py
• frontend/src/components/AI/SuggestionOverlay.jsx
• frontend/src/components/AI/CopilotPanel.jsx
• frontend/src/hooks/useCopilot.js

Files to modify:

• Canvas.js
• drawing.js
• Toolbar.js

Backend:

• routes/copilot.py
• config.py

Skills

Sequence modeling, transformer architectures, Python ML/PyTorch, React real-time UI, model serving, prompt engineering

Key features

• Real-time stroke prediction as ghost overlays
• Context-aware tool and color suggestions
• Pattern recognition (detecting grids, symmetry, repetition)
• Intent prediction (completing shapes, aligning objects)
• Multi-modal suggestions (text annotations, emoji additions)
• User feedback loop for model improvement
• Configurable suggestion aggressiveness
• Keyboard shortcuts to accept/reject suggestions

Challenges

Model training data collection, prediction latency (must be < 100ms), avoiding unhelpful suggestions, balancing creativity vs automation, model size vs inference speed

Getting started

Collect stroke sequence dataset from existing rooms, implement baseline prediction model, add ghost overlay rendering, create copilot API

Tests

Unit: stroke sequence → valid prediction format
Integration: suggestion accepted → added to canvas
UI: ghost overlay renders and can be dismissed
Performance: prediction latency < 100ms
Accuracy: suggestion acceptance rate > 30%
