Stammer.ai is a white label platform for building AI chat and voice agents that agencies resell to their own clients. It covers no-code setup, lead capture, booking and usage-based billing.
About Stammer.ai
What Is Stammer.ai
Stammer.ai is a subscription platform where agencies build AI chat and voice agents, then ship them under their own brand. The company reports 35,000 live agents and 1,300 agencies running on the platform. That number shapes what the product is: not a chatbot you put on your own site, but an AI agent builder an agency uses to sell chatbots to many clients at once.
The core problem it solves is operational. An agency that wants to resell AI chatbot and voice services needs three things at the same time: a builder that doesn't require developers, a way to bill clients for messages and call minutes, and a storefront that carries the agency's name instead of a vendor's. Stammer.ai bundles all three. Chat replies, voice minutes and extra agents come out of a prepaid wallet, and the agency sets its own retail prices on top.
The restrictions matter before you commit. White labeling only starts on the $99 Pro plan, so the $49 Standard tier carries Stammer.ai branding and can't be resold as your own product. Message and voice costs vary by the model you pick, and they're billed separately from the subscription. Everything is web-based, there's no desktop app, and the platform is aimed at agencies rather than a single business running one agent.
Getting Started
- Create an account at app.stammer.ai. The Standard plan starts with a 7-day trial, and Pro starts with 14 days.
- Add funds to the agency wallet. Replies, voice minutes and extra agents draw from that balance, so the account needs credit before an agent can answer anyone.
- Build the first agent: pick a chat or voice template, upload the knowledge base, set the tone, and connect the channels you want it to run on.
- Turn on lead capture and scheduling, then test a live conversation before you hand the agent to a client under your own domain and colors.

Key features
White Label Chat and Voice Agents
Pro and Enterprise plans strip Stammer.ai branding, so an agency runs a white label chatbot platform on its own domain with custom logos and colors. The AI voice agent handles phone calls in the same workspace and can place them too. Chat covers website traffic, SMS and messaging channels. The Standard plan builds the same agents but keeps the vendor's branding, so it's fine for testing and useless for reselling.
Agency Wallet and Usage Reselling
Every reply, voice minute and extra agent is charged against a prepaid wallet, and the agency decides what to charge clients on top. That structure suits agencies because usage scales with client activity instead of a flat seat fee. Published overage rates sit at $0.01 per extra reply and $0.10 per extra voice minute on Standard.
Model Choice and Bring Your Own Keys
Agents can run on different underlying models, and message costs track the model: a lightweight option costs a fraction of a cent per reply, while a frontier model runs closer to a cent. Pro adds the ability to plug in your own OpenAI or Anthropic API keys, which gives an agency direct control over model spend and vendor relationships.
Lead Capture and Appointment Booking
The agents collect names, emails and qualifying details before or during a conversation, then hand the record to the agency or client. Scheduling connects to a calendar so the agent books a slot in the same chat instead of sending the visitor to a separate form. Both features are included from the Standard plan up.
MCP Support and Channel Integrations
Pro unlocks every connector, including web chat, Facebook, Instagram, WhatsApp, SMS and API access, plus Model Context Protocol support for pulling in external data sources and tools. MCP matters for agents that need live information from a CRM, order system or internal database rather than a static knowledge base.
White Label API and Client-Facing Endpoints
Pro exposes API endpoints that run under the agency's own brand, so a client integrating the assistant sees your domain and not Stammer.ai. Enterprise adds custom API endpoints and custom AI functions for workflows the standard builder doesn't cover.
Pros and cons
Pros
- The white label layer is genuinely complete on Pro: domain, logo, colors and API endpoints all carry the agency's brand.
- Usage billing through the wallet makes client costs predictable, since replies and minutes are metered rather than bundled into a flat fee.
- Chat and voice live in one platform, so an agency doesn't need a separate phone agent vendor for after-hours calls.
- Bring-your-own API keys give agencies a way to control model costs and keep their own provider relationship.
- MCP support means agents can pull live data from outside systems instead of answering only from uploaded documents.
Cons
- The $49 Standard plan can't be white labeled, so anyone planning to resell needs the $99 Pro plan from day one.
- Message and voice costs are separate from the subscription and vary by model, which makes a simple monthly quote hard to promise a client.
- No free plan and no desktop app. Trials exist, but a business that wants to test slowly has to do it inside a 7 or 14 day window.
- The product assumes an agency model. A single company running one chatbot pays for reselling features it won't use.
