Limited White-Labeling: Guru branding typically present in web app and extension - internal tool focus vs external customer experiences
English-Only UI: Content supports all languages with translation to 50+, but user interface remains English-only for administrators
Model Abstraction: No user control over LLM selection - optimized for simplicity but reduces flexibility for technical users
AI Credit Management: Usage limits require monitoring and management - organizations may need to purchase additional credits
Enterprise Requirements: Advanced features (IP whitelisting, SSO, SCIM, private models) require Enterprise plan with custom pricing
Setup Complexity: Initial configuration of integrations, permissions, and verification workflows requires thoughtful planning
Change Management: Successful deployment requires organizational adoption of verification workflows and knowledge ownership culture
External Use Limitations: Platform designed for internal teams - not optimized for external customer support chatbots or public-facing agents
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)

Additional Considerations
Cannot create content directly: Glean focuses purely on search and retrieval - not suitable for organizations needing content creation within platform
Platform designed for large organizations: Feature set and pricing optimized for large enterprises - smaller teams may find it overkill and less cost-effective
AI production challenges: 68% of organizations report moving only 30% or fewer AI experiments into full production highlighting persistent scaling difficulties beyond proof-of-concept
Integration complexity: Requires strategic overhaul of processes to ensure seamless technology incorporation into existing workflows
Change management: Overcoming resistance to change demands strong leadership and commitment to fostering innovation and adaptability environment
Data reliability monitoring: Potential for inaccuracies in AI outputs necessitates rigorous monitoring frameworks to ensure data reliability and trustworthiness
Cybersecurity concerns: As AI deployment expands, cybersecurity threats become more pronounced requiring enhanced protective measures for sensitive information
Bias in AI models: Models can inadvertently learn and replicate biases in training data leading to unfair or discriminatory outcomes particularly in hiring, customer service, legal decisions
Training investment required: Enterprises must invest in training workforce to effectively use AI tools - upskilling employees, hiring AI talent, or partnering with consultants
Security risks and shadow IT: Many organizations hesitate due to uncertainties from security risks and shadow IT - ad hoc generative AI adoption comes with heavy risks and costs
Content Maintenance Requirements: Platform value depends on organizational discipline in refreshing knowledge base regularly - requires disciplined maintenance where teams must actively verify cards and keep ownership clear
Search Limitations: Guru's search struggles when knowledge isn't perfectly documented and tagged within its system of Cards - if answer exists only in Slack thread or past conversation, Guru's search won't find it leading to "no results found" dead ends
Enterprise-Specific Limitations: Version history for published cards but not for drafts making collaborative edits hard to track or revert; editor cannot create step-by-step guides or decision trees requiring employees to scan long text
UI Performance Concerns: UI becomes laggy when Knowledge base and team grows - performance degradation at scale
Initial Setup Complexity: New users may find UI slightly complex particularly when managing large collections or reorganizing knowledge across departments - initial setup defining collections, permissions, and verification rules can take time especially for companies with many departments
Pricing Consideration: Per-user seat-based model can be expensive for very large deployments (1,000+ users) vs query-based alternatives - pricing structure requires consideration especially for smaller businesses
Limited Customization: User interface while generally user-friendly may lack flexibility in terms of customization potentially limiting company's ability to fully brand experience or tailor to specific visual preferences
Integration Gaps: While Guru integrates with popular tools like Slack users desire more native integrations with other platforms to further streamline workflows and data synchronization
No Built-In Customer Portal: Guru offers no built-in portal for customers - publishing content online needs extra API work
Internal Focus Trade-off: Platform designed for internal teams - NOT optimized for external customer support chatbots, public-facing agents, or lead capture capabilities
Best For: Companies prioritizing internal knowledge management with verified content workflows and distributed expertise capture
NOT Ideal For: External customer support chatbots, public-facing conversational AI, organizations without verification workflow culture, teams needing deep LLM customization
