Product Function Comparison

Core Functionality Coverage

• DeepCleer:
• Focused on “full-modal + detailed subcategories,” DeepCleer covers text, images, audio, video, and live audio-video stream moderation with 1000+ subcategories. It supports AIGC (AI-generated content) safety identification and real-time streaming moderation (e.g., live broadcast background detection), excelling in deep functionality for complex scenarios.
• Checkstep:
• While Checkstep covers basic content types, its focus is on automated workflow, team collaboration, and compliance reporting (e.g., DSA). It does not emphasize subcategory detail or real-time streaming capabilities.

Summary:

DeepCleer excels in functionality coverage, subcategory depth, and real-time processing capabilities, while Checkstep specializes in basic workflow automation and compliance reporting, with limited complexity and scenario adaptability.

Technology & Innovation

• DeepCleer:
• Built around a fully self-developed, end-to-end solution, DeepCleer employs cutting-edge models like GAN and LSTM, offering deep integration of fasttext, NLP algorithms, and heterogeneous computing. It supports real-time streaming computation and rapid model updates in seconds, forming a "data-model-scenario" loop that ensures technical autonomy and global service capabilities.
• Checkstep:
• Checkstep relies on external technologies, emphasizing tool development at the application layer. Its AI-driven platform uses custom classifiers for decision-making, with scalability through BPO (Business Process Outsourcing) partnerships, but lacks the transparency of self-developed core models.

Performance Metrics:

• DeepCleer:
• Achieves an accuracy rate over 99.99%, with latency as low as 60ms. Its weekly data iterations exceed 5 million, with T+7 deployments and incremental updates every hour.
• Checkstep:
• No clear performance metrics, only vague references to harmful content removal time ("<1 second"), with no disclosed model iteration cycle or optimization details.

Industry Fit & Depth of Solution

• DeepCleer:
• Covers over 20 industries, including financial services, and provides deep customization for complex scenarios like AIGC safety and minor protection. Risk scenario coverage reaches 99.99%.
• Checkstep:
• Primarily focused on online community content moderation, Checkstep specializes in basic compliance (e.g., DSA) and community workflow optimization. Its industry focus is limited.

Client Cases & Market Validation

• DeepCleer:
• Serves 3000+ clients, including industry leaders such as Spicychat.ai, SHEIN, and DIOR (China), demonstrating strong reliability in highly regulated environments. It has protected 12.1 billion global accounts and intercepted 18.8 billion risk events, showcasing high concurrency handling.
• Checkstep:
• Focuses on mid-sized online communities, with clients like Trustpilot and WeTransfer. Revenue for 2021-2023 was modest ($2.4 million), and the company is still in a growth phase, lacking large-scale enterprise cases.

Summary & Recommendations

Key Differences:

• Technology & Coverage:
• DeepCleer offers advanced, self-developed AI capabilities, covering a wide range of content types, with deep risk categorization and real-time streaming moderation. Checkstep focuses on streamlined workflows and basic content safety, relying more on external tech.
• Scale & Industry Adaptability:
• DeepCleer’s solution is suited for large-scale, complex industries with high-performance needs, such as AIGC, gaming, and live streaming. Checkstep is more appropriate for smaller, compliance-driven platforms focusing on European markets.

Recommendation:

• Choose DeepCleer for complex industries (e.g., AIGC, gaming, live streaming) requiring high-performance, full-stack moderation with deep customization.
• Choose Checkstep for smaller-scale European social media platforms needing a focus on automated workflows and compliance (e.g., DSA), but with a need for further evaluation regarding scalability and feature depth.

Conclusion:

DeepCleer stands out in complex, multi-industry content safety with its full-stack solution, while Checkstep is suitable for smaller platforms focused on compliance and automation. For high-demand, global scenarios, DeepCleer offers the best solution.
