Limitations & Considerations
  • No Custom Chatbot Flows: Cannot create your own custom chatbot flows limiting advanced functionality for sophisticated conversation paths
  • No Live Chat Integration: Lacks human agent takeover preventing seamless transition from bot to human support
  • Clunky Lead Generation: Data collection (name, email capture) described as clunky, causing some users to disable feature
  • Limited Segments: Cannot create custom segments of contacts for targeted messaging and analytics
  • Document Processing Limitations: Won't be good at questions dealing with whole document - works by slicing text and finding relevant sections
  • Training Data Size Limits: Limited to how big training data set you can use, problematic for organizations with extensive documentation
  • Expensive After Basic: Users find Chatbase expensive after basic plan, limiting access to essential features
  • Complex Integration: Integrating with existing systems can sometimes be complex requiring technical expertise
  • Limited Marketing Features: Missing advanced features for proactive engagement and marketing outreach campaigns
  • OpenAI Account Limitation: Only one OpenAI account linking can lead to performance issues and technical difficulties
  • Accuracy Issues Reported: When transitioning between GPT versions, users encountered accuracy problems with incorrect or nonexistent responses
  • Information Leakage: Instances where chatbot retrieved or shared information beyond training resulting in inaccurate responses
  • Reliability Problems: Constant breaks and errors in production with system crashing or returning nonsensical errors (Trustpilot reviews)
  • Abysmal Customer Support: Painfully slow response times and inability to understand basic problems per negative Trustpilot reviews
  • Billing Issues: Continued charges after subscription cancellation with useless support providing no clear answers or refunds
  • High cost barrier: ~$50/user/month with ~$60K minimum ACV excludes SMBs, startups, and budget-conscious teams
  • No public pricing: Requires sales contact creating friction for evaluation and budget planning vs transparent competitors
  • Paid POCs: No free trial, POCs reportedly cost up to $70K for large enterprise pilots
  • Renewal increases: 7-12% annual price increases unless renewal caps negotiated upfront
  • NO FedRAMP certification: Not suitable for US federal government deployments
  • Limited consumer channels: No native WhatsApp, Telegram integrations - designed for internal enterprise use only
  • Complex implementation: Initial indexing takes "few days" depending on data volume, requires enterprise IT coordination
  • Cross-language queries in early access: English query finding Spanish documents still in testing phase
  • Best for: Large enterprises (1K-100K users) with complex permission hierarchies, $60K+ budgets, and need for permissions-aware AI across 100+ datasources
  • NOT suitable for: SMBs, startups, simple document Q&A without permission requirements, organizations prioritizing transparent pricing
  • 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-4, GPT-3.5) and Anthropic (Claude) - 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

Best For: Permissions-aware AI is genuinely differentiated - real-time enforcement across 100+ datasources addresses critical enterprise concern

Migration & Switching Considerations

Switching between Chatbase and Glean requires careful planning. Consider data export capabilities, API compatibility, and integration complexity. Both platforms offer migration support, but expect 2-4 weeks for complete transition including testing and team training.

Pricing Comparison Summary

Chatbase starts at $15/month, while Glean begins at $50/month. Total cost of ownership should factor in implementation time, training requirements, API usage fees, and ongoing support. Enterprise deployments typically see annual costs ranging from $10,000 to $500,000+ depending on scale and requirements.

Our Recommendation Process

  1. Start with a free trial - Both platforms offer trial periods to test with your actual data
  2. Define success metrics - Response accuracy, latency, user satisfaction, cost per query
  3. Test with real use cases - Don't rely on generic demos; use your production data
  4. Evaluate total cost - Factor in implementation time, training, and ongoing maintenance
  5. Check vendor stability - Review roadmap transparency, update frequency, and support quality

For most organizations, the decision between Chatbase and Glean comes down to specific requirements rather than overall superiority. Evaluate both platforms with your actual data during trial periods, focusing on accuracy, latency, ease of integration, and total cost of ownership.
