What is Stammer?
Stammer.ai is a fully white-label AI SaaS platform that enables digital marketing agencies, AI agencies, and automation agencies to build, sell, and manage custom AI chatbots and AI voice agents under their own branding. The platform allows agencies to deploy AI agents that handle customer support 24/7, qualify leads automatically, schedule appointments, answer customer questions, and drive revenue across 6+ channels including websites, social media, messaging platforms, and phone calls. Clients never see Stammer's branding—only the agency's custom domain, logo, colors, and company name.
Key features include a fully white-labeled dashboard, custom domain support (agents.youragency.com), client sub-account portals with real-time analytics dashboards showing ROI metrics, white-label API for integrating into any tech stack (CRM, website, app), 20+ AI chat agents and 20+ AI voice agents on the Agency plan, 1M+ characters knowledge base capacity, live chat with human handoff capability, MasterChat for internal AI agents, and support for user's own API keys to skip usage costs. The platform supports 160+ languages, offers 99.9% uptime, and has processed 12M+ conversations across 35K+ live AI agents.
Stammer is specifically designed for AI agency owners, web design agencies, digital marketing agencies, and automation agencies looking to scale their operations by adding AI solutions to their service portfolio without hiring developers. Agencies can position AI agents as their proprietary technology, charge premium prices ($300-$500 MRR per client or higher), stack multiple revenue streams (voice + chat + email for $800-$1,200/month per client), and scale from $0 to $50K MRR in 6 months. The platform is GDPR compliant and made in the USA.

Frequently asked questions about Stammer
What is Stammer.ai (TL;DR)?
Stammer.ai lets you build, sell, and manage both chat-based AI agents and voice-based AI agents under your own brand at scale. You can customize everything—name, logo, colors, links—so it looks and feels like your own platform. Clients never see Stammer, only your company branding on your custom domain.
What can AI Agents do?
Chat AI agents create website chatbots, integrate with social media channels or CRM platforms to handle customer support, knowledge recall, sales outreach, lead generation, and scheduling. Voice AI agents answer inbound phone calls, replace voicemail, handle repetitive conversations, make outbound calls for lead qualification, and transfer to humans when needed. Both work 24/7 across 6+ channels.
How much do messages and calls cost?
Each AI agent runs on the model you choose, and cost depends on that model. You can also connect your own OpenAI API keys and skip usage costs for chat messaging only. Chat messaging: GPT-4.1-nano = $0.001/message, GPT-4o-mini = $0.002, GPT-4o = $0.01, GPT-5 = $0.01, Claude 3.7 Sonnet = $0.03, Grok 2 = $0.02. Voice calls: GPT-4.1-nano = $0.11/minute, GPT-4.1-mini = $0.12, GPT-4.1 = $0.16, GPT-5 = $0.15, Claude 3.7 Sonnet = $0.17.
What is the Agency Wallet?
The Agency Wallet is your prepaid balance for usage on the Stammer platform. Each time a chat agent replies or a voice agent answers a call, the cost for usage is taken from your wallet. Your clients also get their own Sub-Account Wallet where they pay you directly for usage. Example: You buy a GPT-4o chat response for $0.01 and resell it to your client for $0.05, keeping $0.04 profit.
How do I add funds to my wallet?
Two ways: (1) Manual top-up—add money anytime with the '+ Add Balance' button. (2) Auto-billing—set a low balance trigger and recharge amount, like auto-reload $10 when balance drops below $10. Both methods are also available to your client's Sub-Account wallet.
Do I get credits when I sign up?
Yes. Paid plan subscribers get free credit added to their Agency Wallet. This helps you test both chat and voice agents and onboard your first client without extra upfront costs.
How do agencies make money with Stammer?
Agencies monetize in three ways: (1) Set-Up fees—charge one-time onboarding fee when building and launching an agent for a client. (2) Subscriptions—offer ongoing packages for chat or voice AI agents, usually $300-$500 per month per agent. (3) Usage fees—add markup on extra messages, call minutes, or storage (commonly 3-5x your cost). You choose one, two, or all three options. Every AI agent launched generates recurring revenue.
How does billing work for clients?
Your clients pre-load funds into their Sub-Account Wallet. Each time a chat agent sends a message or a voice agent takes a call, funds are deducted at the price you set. When their balance runs low, they add more funds to their wallet. 100% of these funds gets sent to you as new revenue—you keep the full markup.
Can I use my own API keys?
Yes, you can use your own OpenAI API keys and skip usage costs for chat messaging only. This applies to chat agents on all plans. Voice agents still incur usage costs per minute regardless of API keys.
How does human handoff work?
Human handoff is done via a combination of editing the base system prompt and adding automation within the system it is integrated into. When the AI determines a transfer is needed, it routes to your human team. This requires custom prompt configuration rather than a built-in button feature.
