Limitations & Considerations
Managed service approach: Less control over underlying RAG pipeline configuration compared to build-your-own solutions like LangChain
Vendor lock-in: Proprietary platform - migration to alternative RAG solutions requires rebuilding knowledge bases
Model selection: Limited to OpenAI (GPT-5.1 and 4 series) and Anthropic (Claude, opus and sonnet 4.5) - no support for other LLM providers (Cohere, AI21, open-source models)
Pricing at scale: Flat-rate pricing may become expensive for very high-volume use cases (millions of queries/month) compared to pay-per-use models
Customization limits: While highly configurable, some advanced RAG techniques (custom reranking, hybrid search strategies) may not be exposed
Language support: Supports 90+ languages but performance may vary for less common languages or specialized domains
Real-time data: Knowledge bases require re-indexing for updates - not ideal for real-time data requirements (stock prices, live inventory)
Enterprise features: Some advanced features (custom SSO, token authentication) only available on Enterprise plan with custom pricing
NO Public REST API: Cannot manage agents, create workflows, or query knowledge base programmatically - blocks developer integration
NO Official SDKs: No Python, JavaScript, Ruby, Go, or any language SDK for programmatic access - workflow automation only
NO CLI Tools: No command-line interface for automation or scripting - dashboard-only management
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
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
Platform Category Mismatch: Fundamentally a workflow automation platform (competes with Zapier/Make) NOT a RAG-as-a-Service platform - architectural comparison to CustomGPT.ai is misleading
