What is Stammer?
Stammer is a white-label AI agent builder that lets agencies create, brand, and resell chat and voice AI agents to unlimited clients under their own domain and branding. It provides the full infrastructure for building AI-powered customer service, lead generation, and appointment-setting agents — without writing code — and packages them into a client-facing platform that carries no Stammer branding.
Features & Benefits
- AI Chatbot Builder – Build conversational chat agents for customer support, lead generation, appointment setting, and sales outreach, deployable on websites, social media channels, and CRM platforms.
- AI Voice Agent Builder – Create voice AI agents that handle inbound phone calls, make outbound calls for lead qualification, replace voicemail, and transfer to human agents when needed.
- White-Label Dashboard – Rebrand the entire platform with a custom domain, logo, and color scheme so clients interact with the agency’s product, not Stammer’s.
- Client Sub-Accounts – Set up individual client accounts with separate wallets, usage tracking, and billing, with full pricing control and no revenue sharing.
- Knowledge Base – Train AI agents on custom content up to 5M characters to give agents accurate, brand-specific responses.
- Live Chat & Human Handoff – Combine AI agent responses with live human chat support and transfer conversations to a human agent when needed.
- MasterChat – Deploy internal AI agents for use within the agency’s own operations rather than for client-facing use.
- Custom AI Functions – Build custom logic and behaviors into agents beyond standard conversational responses (Full SaaS and Enterprise plans).
- Bring Your Own API Keys – Connect personal OpenAI API keys to bypass platform usage costs for chat messaging.
- Multi-Model Support – Select from GPT-4.1-nano, GPT-4o-mini, GPT-4o, GPT-5, Claude 3.7 Sonnet, and Grok 2 as the underlying model for each agent.

Real-World Applications
Digital agencies looking to add AI services to their existing offerings can use Stammer as an AI agent builder to launch a recurring revenue stream without building proprietary technology. Chat and voice agents can be configured for a client’s specific use case — customer support, lead qualification, or appointment booking — and delivered under the agency’s own brand. Agencies set their own pricing, mark up usage costs, and collect 100% of client revenue.
Web design and marketing agencies serving small and medium businesses may use Stammer to upsell AI chatbot and voice agent services to existing clients without adding development overhead. The no-code builder lets non-technical team members configure and deploy agents, while the white-label API enables integration into client websites and CRM systems as a bespoke service. One-time setup fees combined with monthly subscriptions create a predictable recurring income model.
Customer service operations deploying AI agents for inbound call handling and chat support can use Stammer’s voice AI agents to manage high call volumes without additional staffing. Human handoff ensures that complex or sensitive conversations escalate to a live agent rather than being handled entirely by AI. The knowledge base trains agents on company-specific information so responses remain accurate and on-brand.
Enterprise teams and SaaS companies requiring large-scale agent deployment can access Stammer’s enterprise tier for custom integrations, single sign-on, self-hosting options, MCP server integration, and custom AI models. The sub-account billing structure scales across hundreds or thousands of clients with individual usage tracking and automated wallet top-ups, removing manual billing overhead at scale.
