Limitations & Considerations
Single Flow Management: Larger bots get unwieldy because everything lives inside single flow - no folder organization like ManyChat for complex conversation trees
NO Live Chat Support: Doesn't include live chat feature - blended human-AI support approach unavailable without Zapier workarounds
Separate Bots Per Channel: Need to build separate chatbot for website vs WhatsApp - no unified multi-channel bot creation
Limited Advanced Features: Once you need fallback behavior, confidence scoring, or content indexing control, limitations appear
Barebones Analytics: Analytics pretty barebones compared to enterprise platforms with detailed conversation intelligence and custom report builders
Knowledge Base Management Challenges: For e-shop or site with lots of pages, nightmare to sort which pages to add - no Excel import for bulk management
Data Quality Dependency: If data isn't clean, bot might pull irrelevant answers - heavily dependent on training data quality and curation
NO Flow Import/Export: Cannot import or export flows, no option to copy or duplicate full group of blocks for version control
Screen Reader Accessibility: Does not support accessibility for blind users using screen readers - inclusivity limitation cited in reviews
Setup Time Investment: Configuring chatbot tone takes manual effort, assembling strong knowledge base not plug-and-play despite 5-minute claims
Learning Curve: Takes while to learn how to use builder and tools despite drag-and-drop interface and visual design
Integration Gaps: Heavy reliance on Zapier might limit functionality if service experiences downtime - not all third-party platforms supported natively
Interface Overwhelm: Drag-and-drop can be overwhelming for new users unfamiliar with chatbot design principles and flow logic
Best for Small-to-Medium Bots: Works best for small to medium-sized bots rather than massive enterprise-level projects with complex requirements
B2B Messaging Gaps: NO native Slack, Microsoft Teams, or Telegram integrations - limits enterprise internal use cases
NO Official SDKs: Must build own HTTP clients or rely on community implementations - no official JavaScript or Python SDKs
Enterprise Compliance Gaps: NO SOC 2, HIPAA, ISO 27001 certifications disqualifies platform for regulated industries (healthcare, finance, government)
NOT a RAG-as-a-Service Platform: Fundamentally a knowledge base tool with embedded AI—not a flexible RAG backend
AI Answers Enterprise-Gated: Core AI capabilities require expensive Enterprise plan (~$39K/year)—not available on $249/month Small Business tier
Undisclosed AI Model: No transparency on LLM provider—users cannot select or customize models
Limited Data Source Flexibility: PDF, public web, Zendesk only—missing Google Drive, Dropbox, Notion, SharePoint, YouTube
No Automatic Content Syncing: Manual updates through visual editor—no real-time integration with external knowledge sources
Missing Consumer Messaging: No Slack, WhatsApp, Telegram, Microsoft Teams native integrations (confirmed by user reviews)
No Omnichannel Messaging: Primarily website embedding and help desk integration—limited multi-channel support
Cannot Edit on Mobile: Guide creation and editing restricted to desktop—mobile limitation for on-the-go teams
No Real-Time Analytics: Flow reports update every 15 minutes—not true real-time monitoring
Limited Developer API: No Python/Node.js SDKs, GraphQL, Swagger specs, or API sandbox for testing
Overage Pricing Escalation: View limits can trigger expensive automatic upgrades after 2 consecutive months
Not Ideal For: Developers seeking pure RAG API, multi-tenant SaaS RAG backends, use cases needing model selection/fine-tuning, or flexible data source integration
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
Additional Considerations
Simplicity as Strength: Platform strongest feature is simplicity designed so anyone regardless of technical background can build powerful GPT-enabled chatbot quickly
No-Code Accessibility: Drag-and-drop interface makes creating AI chatbots accessible to non-technical users with minimal learning curve

Latest AI Models: Powered by latest large language models including GPT, Gemini, and Claude ensuring cutting-edge performance
WhatsApp Native Integration: Works seamlessly on websites and WhatsApp providing mobile-first customer engagement capabilities
Proven Reliability: G2 reviews praise "chatbots have never gone down" with 4.8/5 rating from 53-63 reviews demonstrating strong uptime
Support Deflection Success: User reported 45% of support questions resolved reducing email inquiries from 1,500+ monthly for efficiency gains
Security & Privacy: Industry-standard security with data encryption in transit and at rest, GDPR compliant with regular security audits
Training Flexibility: Upload documents, add websites, connect data sources to train AI chatbot automatically on custom content
Trade-Off: Simplicity vs Advanced Features: Exceptional usability and ease comes at cost of advanced features like custom flows, live chat, enterprise compliance
Best Fit: Small to mid-size businesses prioritizing rapid deployment, simplicity, and cost-effectiveness over enterprise-grade features and compliance
Limited UI customization: Limited ability to customize user interface and workflows to match specific brand requirements is primary user concern
Basic collaboration tools: Without real-time editing or advanced team management features can hinder team productivity when multiple people need to work together
No offline access: Guides unavailable without internet connectivity reducing usability in areas with unreliable internet
Performance degradation: Can degrade with very large or complex guides causing slower responsiveness indicating scalability concerns
Restricted language options: Limit efficient creation of multilingual content which may be barrier for global organizations
Mixed media support missing: Users find missing features wishing for mixed media support and enhanced reporting tools
Step ordering difficulties: Users report limitations in feature usability and difficulties with step ordering though support offers helpful workarounds
Requires coding knowledge: Unlike most competitors, doesn't advertise as no-code platform - need coding knowledge to track events, target users, stream data, and style content
Image workflow limitations: Inability to use images in base offering limits utility in some workflows with some advanced features requiring extra costs
View-based pricing: Charges additional fees based on guide views - customers exceeding 4,000 guide views/month pay extra $250-500 monthly depending on volume
Integration reliability: Users find lack of integrations limits ability to fully connect Stonly with other tools - Stonly/Zendesk integration isn't as reliable as desired (stops working every few weeks)
