RobotReviewer markets itself as an AI tool that automates risk of bias (RoB) assessment for randomized controlled trials. However, this automation is more pseudo-intelligent convenience than robust scientific innovation.

• The system relies heavily on natural language processing (NLP) heuristics that frequently misinterpret complex methodological descriptions.
• It often misses nuanced biases or contextual caveats that human reviewers easily detect.
• False positives and negatives in bias detection are common, undermining trust in its output.

• RobotReviewer provides limited explanations for its judgments, offering no detailed rationale or evidence linking text snippets to bias ratings.
• The black-box nature of the underlying algorithms prevents users from critically appraising or challenging its assessments.
• There is no user control to adjust or calibrate the AI’s sensitivity or specificity for different domains or trial designs.

• Users unfamiliar with risk of bias frameworks may overtrust RobotReviewer’s outputs, leading to flawed inclusion/exclusion decisions.
• The tool does not replace expert judgment but risks becoming a crutch, especially in rapid or resource-limited reviews.
• Inconsistencies between RobotReviewer and manual assessments are well-documented, raising reproducibility concerns.

• RobotReviewer is designed primarily for classic RCTs and struggles with non-standard trial designs, cluster trials, or adaptive trials.
• It does not handle other study designs (e.g., observational studies) or different bias tools (e.g., ROBINS-I).
• The system lacks integration with broader review workflows, limiting its utility beyond isolated bias assessment.

• The project sees infrequent updates, and user feedback channels are limited.
• The AI model may become outdated as reporting standards evolve.
• Limited community engagement reduces transparency and iterative improvement.

RobotReviewer offers a tempting shortcut in risk of bias assessment but ultimately fails to deliver consistent, transparent, and trustworthy automation. Its limitations in accuracy, explainability, and scope mean it should only be used as a preliminary aid, never a substitute for expert appraisal.

Recommendation: Use RobotReviewer cautiously and always in conjunction with thorough manual review. For serious systematic reviews, prioritize human-led, transparent risk of bias assessments augmented by, not replaced by, AI tools.
