Stammer

Pick Stammer if you run an AI agency, web design firm, or consultancy looking to add a recurring revenue stream with minimal dev work. The white-labeling is comprehensive—you get your own domain, branding, and client portal that makes you look like the original developer. Setup is no-code, so you can have a client live in hours, not weeks. Pass on Stammer if you need advanced AI capabilities like custom model fine-tuning, multilingual support beyond basic English, or complex workflow automation. The AI agents are trained on your business data but follow a relatively rigid script—they’re great for FAQs and lead gen but not for nuanced conversations. The closest alternative is arguably Voiceflow or Tidio, but Stammer’s differentiator is its pure agency reseller play. Voiceflow offers more flexibility in conversation design, while Stammer focuses on quick deployment and maximum margin control. If you want to charge $500+/mo per client and keep all of it, Stammer wins. But if you want to build complex conversational flows from scratch, Voiceflow is better. Real-world caveats: The phone voice agent quality is good but not indistinguishable from human—background noise or heavy accents can trip it up. The messaging integration works well, but some custom channels require API work. Also, pricing page details aren’t fully public; you need to start a trial to get specifics beyond "starting at $49/mo". The 14-day free trial is a plus, but no credit card required is convenient. Overall, Stammer is a revenue tool for agencies, not a standalone AI platform for enterprises. It’s best for those who sell services to SMBs and want to add AI without hiring engineers.

Stammer is a white-label platform that lets AI agencies and businesses build and deploy AI chat and voice agents across multiple channels. It is designed for customer support, lead qualification, and appointment booking, operating 24/7 with human-like interaction. With over 35,000 live agents and 12 million conversations processed, Stammer emphasizes reliability (99.9% uptime) and full customization under your own brand. Key features include a no-code dashboard to create both AI chatbots for websites and messaging apps (Instagram, Facebook Messenger, WhatsApp) and AI voice agents for phone calls with natural conversation flow. Automated lead collection and scheduling (Google Calendar, Calendly, Cal.com) are built-in, along with seamless human hand-off when needed. The platform also offers a client portal with real-time analytics to demonstrate ROI, and a rebrandable API for integrating into existing tech stacks. Stammer is specifically tailored for agencies that want to resell AI solutions as their own product. It provides complete white-label control (domain, logo, colors), pricing flexibility (keep 100% markup), and integration revenue opportunities. Use cases span home services, e-commerce, healthcare, real estate, legal, and other service sectors. Compared to competitors, Stammer stands out for its agency-focused reseller model, no revenue sharing, and the ability to bundle voice, chat, and email solutions for recurring revenue. Its main limitation is a lack of advanced NLP customization beyond business data training.
