CrowdSynthetic vs Decode: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of CrowdSynthetic and Decode — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
CrowdSynthetic
mksimple-blip (GitHub)
Open-source crowd safety simulator that predicts and visualizes congestion to help prevent dangerous crowding.
Key features
- Congestion Prediction: Uses AI-driven simulation to forecast areas of high crowd density ahead of time, enabling proactive mitigation measures.
- Movement Visualization: Renders movement trajectories and density maps so users can see evolving crowd flows and identify bottlenecks visually.
- Scenario Simulation: Allows creation and testing of different venue layouts, entry/exit strategies, and event conditions to evaluate crowd behaviour under varied scenarios.
- Proof-of-Concept Open Source: Published on GitHub as a POC, enabling developers and researchers to inspect, modify, and extend the codebase.
- Real-Time Tracking (POC capability): Demonstrates the ability to incorporate tracking inputs to simulate current crowd states and produce near real-time congestion forecasts.
- Extensible Integration: Designed for integration with external data sources and monitoring systems so teams can adapt the simulator to operational workflows.
- Predicts crowd congestion ahead of time using AI models
- Visualizes movement and crowd flow in simulation environments
- Real-time simulation and tracking of pedestrian dynamics (POC)
- Open-source codebase available on GitHub for inspection and extension
- Designed for scenario testing and safety analysis in crowded environments
Best for
- Event Planning: Simulate crowd flows for concerts, festivals, and sports events to identify potential choke points and adjust layouts or staffing.
- Transit Hub Management: Forecast congestion in train stations and airports during peak times to inform scheduling and crowd control measures.
- Emergency Preparedness Training: Run evacuation and emergency scenarios to test response plans and optimise egress routes.
- Venue Design Evaluation: Test different architectural or ingress/egress designs for new or renovated venues to minimize crowding risks.
- Operational Monitoring: Combine live tracking data with simulation to provide early warnings to safety teams and enable proactive interventions.
- Research and Development: Serve as a research platform for academics and engineers studying crowd dynamics and developing improved predictive models.
- Monitoring and predicting crowd congestion at events, transit hubs, and venues
- Scenario testing for crowd-control strategies and emergency evacuation planning
- Research and development of pedestrian flow models and safety algorithms
- Prototyping integrations with video analytics or sensor feeds for real-time monitoring
- Demonstration and education of AI-driven crowd safety techniques
Decode
Entropik Technologies
A human insights platform that uses emotion AI, webcam eye tracking, and predictive models to test creative, products, and experiences before launch.
Key features
- Emotion AI Measurement: Face emotion, voice emotion, and text sentiment analysis reveal how respondents actually feel during a study rather than only what they report in an answer.
- Webcam Eye Gaze Tracking: Real eye tracking runs through a participant's own webcam with zero hardware, producing attention heatmaps that show where people look first and what they miss.
- AI Creative Insights: Neuro AI predicts attention, emotional resonance, brand recall, and conversion impact for ad creative, packaging, OOH, and web layouts before media spend is committed.
- Synthetic Audience: Build reusable synthetic personas and compare how each creative performs persona by persona ahead of fielding a study with real respondents.
- AI Moderator: Runs moderated and unmoderated interviews at scale, then extracts themes, emotions, and supporting evidence from raw interview and video feedback automatically.
- Shopper and Shelf Simulation: Simulates real-world shelf and pack testing with attention heatmaps, shelf visibility analysis, planogram optimization, and purchase-intent prediction.
- UX Research Suite: Prototype testing, unmoderated task studies, usability and wireframe testing, card and tree sorting, and live website and app testing, each enriched with gaze and emotion data.
- Global Respondent Panel: Access to more than 103 million respondents worldwide, or bring your own panel free of charge on any plan.
Best for
- Pre-Flight Ad Testing: Comparing creative variations and messaging options to predict which version earns attention and recall before buying media.
- Packaging and Shelf Decisions: Testing pack designs and planograms in a simulated retail environment to forecast visibility and purchase intent.
- Product Concept Validation: Screening product concepts, storyboards, and innovation ideas for early-stage market fit before committing development resources.
- UX Friction Discovery: Running prototype and usability studies where webcam eye tracking and emotion signals expose confusion users cannot articulate.
- Qualitative Research at Scale: Using the AI Moderator to conduct and synthesize many interviews into structured themes instead of manual transcript coding.
- Brand Tracking and Price Testing: Running recurring consumer studies on brand perception, pricing, and the customer journey across multiple markets.
