  • NO Developer Console: No API sandbox, testing environment, or technical documentation for developers
  • Black Box RAG Implementation: Vector database, embedding models, similarity thresholds completely undisclosed - no transparency
  • No RAG Benchmarks: No published accuracy metrics, retrieval precision/recall, or latency measurements for evaluation
  • Search Fuzziness Constraint: Lower fuzziness values limit searches to first 1,500 files - meaningful limitation for large deployments
  • Character Storage Limits: 50M character maximum on Business tier - may constrain large enterprise knowledge bases vs unlimited competitors
  • Unpredictable Credit Consumption: Most common user complaint - 'credits depleted quickly and unpredictably' makes budgeting difficult
  • US-Only Data Residency: No documented EU data residency option - blocks customers with strict data localization requirements (GDPR, Digital Sovereignty)
  • No ISO 27001 Certification: Only SOC 2 Type II documented - ISO 27001 absence may limit enterprise procurement in regulated industries
  • 1-Day Free Tier Log Retention: Severely limits troubleshooting and security incident investigation vs 30+ day industry standard
  • Learning Curve for Complex Workflows: Despite 'vibe coding' simplicity, sophisticated multi-agent systems and delegation rules require workflow design expertise
  • Support Quality Inconsistency: Mixed reviews noting slow/unresponsive support for non-enterprise tiers - support quality varies significantly by plan
  • No Manual Model Performance Comparison: Cannot A/B test different LLMs or compare model performance - manual experimentation required
  • Limited RAG Customization: Cannot tune embedding models, chunk sizes, overlap, similarity thresholds, reranking - black box implementation
  • Credit-Based Pricing Opacity: Difficult to forecast costs vs fixed per-seat or per-query pricing - budget planning challenging
  • NOT Ideal For: Developers needing RAG APIs, teams requiring transparent RAG implementation, EU data residency requirements, organizations needing predictable pricing, technical teams wanting embedding/retrieval control
