What is Stammer?

Stammer is a white label AI chatbot platform built specifically for digital agencies that want to offer AI-powered customer engagement tools under their own brand. Agencies configure the platform with their domain, logo, and custom embed links, then deploy chat agents on behalf of clients without any client-facing Stammer branding visible. The core business problem Stammer solves is the build-versus-buy gap agencies face when clients request AI chat capabilities. Building a proprietary chatbot infrastructure is expensive and slow; white-labeling a third-party tool without proper branding controls undermines the agency's own positioning. Stammer closes that gap by providing a fully brandable backend — including a white-labeled API — so agencies can deliver a finished product that looks and feels like their own technology. Each client gets a dedicated sub-account, giving the agency centralized control over deployments while keeping client data and configurations separated. AI agents built on Stammer can handle lead qualification, appointment scheduling, follow-up sequences, and inbound customer support across web chat, SMS, and email channels. The messaging credits system includes rollover and auto-billing, which removes the friction of manual credit management for agencies running multiple active client deployments. Stammer's multilingual support covers over 160 languages, extending its value to agencies with international client portfolios. The platform's REST API integrates AI agents with third-party CRMs, marketing platforms, and workflow tools, allowing the agency to position the chatbot as one component of a broader automation stack rather than a standalone widget. Agencies with a small client base generating low monthly conversation volume may find Stammer's paid-only model harder to justify compared to freemium alternatives like Botpress. The platform delivers its highest ROI when an agency has at least several active client accounts generating consistent chatbot traffic.

Stammer is a white label AI chatbot platform that lets agencies build, brand, and resell AI-powered chat agents to clients under their own domain and logo.

Stammer is widely used by professionals, developers, marketers, and creators to enhance their daily work and improve efficiency.

Key Features

1

White Label Customization

Stammer allows agencies to deploy the entire platform under their own domain, logo, and brand identity. Client-facing interfaces show no Stammer branding, and the agency's name appears across all touchpoints — including embed scripts and API responses — giving the agency full brand ownership over the product they deliver to clients.

2

AI Chatbot Creation

Agencies build AI agents inside Stammer that handle inbound lead qualification, appointment booking, multi-step follow-up sequences, and customer support queries across web chat, SMS, and email. Each agent can be configured with custom knowledge bases, escalation rules, and response tone to match the client's brand voice and service requirements.

3

Client Sub-Account Management

Each client operates inside a dedicated sub-account, keeping configurations, conversation histories, and credit balances fully separated. Agencies manage all sub-accounts from a single admin dashboard, enabling centralized oversight without requiring client access to the agency's master account or billing information.

4

Messaging Credits System

Stammer's credit system tracks conversation volume per client account, with unused credits rolling over monthly rather than expiring. Agencies can configure auto-billing thresholds to automatically purchase additional credits when a client account runs low, eliminating manual monitoring for accounts with variable but consistent conversation volumes.

5

Comprehensive API Access

The fully white-labeled REST API allows agencies to connect Stammer's AI agents to virtually any third-party platform their clients use — CRMs, e-commerce backends, calendar systems, or custom-built applications. This API layer transforms the chatbot from a standalone tool into an integrated component of the client's broader automation infrastructure.

Pros & Cons

✓ Pros (9)

White Label Customization Agencies maintain complete brand ownership across every client-facing touchpoint, including the API layer. No visible Stammer branding in any deployed product means the agency presents a cohesive, proprietary-feeling service rather than a reskinned third-party tool — which directly supports premium pricing with clients.

AI Chatbot Creation The chatbot builder supports multi-step, multi-channel agent workflows that go beyond simple FAQ bots. Lead qualification, appointment booking, and follow-up sequences can all be configured within the same agent, reducing the number of separate tools an agency needs to manage a client's full customer engagement pipeline.

Client Sub-Account Management Centralized sub-account management gives agencies operational clarity across their entire client portfolio without context-switching between separate logins. Billing, credit allocation, and configuration access are all managed from one dashboard, which becomes particularly valuable as an agency scales past five or more active client accounts.

Messaging Credits System The rollover credit model prevents agencies from losing paid capacity at month-end due to lower-than-expected client usage. Auto-billing thresholds mean high-volume client accounts scale their credit consumption automatically without manual intervention, reducing the operational overhead of credit management across a diverse client portfolio.

Comprehensive API Access The white-labeled REST API connects Stammer's AI agents to any platform using standard webhook and API integration patterns — including CRMs like Salesforce and HubSpot, e-commerce platforms like Shopify, and calendar tools like Calendly. This integration depth allows agencies to position Stammer not as a chatbot product but as an AI infrastructure layer.

Scalability Stammer's account architecture is designed to grow from a single-client pilot to a full SaaS agency model without requiring platform migration. Agencies can add client sub-accounts, expand credit pools, and increase API throughput as their client base grows, without rebuilding their deployment infrastructure.

Multilingual Support AI agents built on Stammer can conduct conversations in over 160 languages without requiring separate agent configurations per language. For agencies serving international clients or managing chatbots for businesses with multilingual customer bases, this eliminates the need to maintain parallel agent setups for different language markets.

Robust Integration Capabilities Stammer's integration layer covers the most common platforms agencies encounter in client environments — marketing automation, CRM, e-commerce, and scheduling tools — through standard API connections. Agencies can extend this further using webhook triggers to connect Stammer agents to custom internal systems or less common third-party platforms.

Community Development Approach Stammer's product roadmap is influenced by active user feedback from its agency community, meaning frequently requested features — such as new integration connectors or credit management controls — have a defined path to implementation. Agencies using the platform early gain disproportionate influence over which operational gaps get prioritized in upcoming releases.

✕ Cons (3)

Complexity for Beginners Agencies new to white-label SaaS models may find the combination of sub-account management, credit allocation, and API configuration overwhelming during initial setup. The platform assumes the user understands agency-client billing structures and chatbot deployment concepts before onboarding, with limited step-by-step guidance for teams starting from scratch.

Pricing for High Volume Stammer's messaging credit model becomes increasingly expensive as client accounts generate higher conversation volumes — a cost that compounds across a large agency portfolio. Agencies projecting significant growth in chatbot-handled conversations should model their credit costs at scale before committing to the platform to avoid margin compression later.

Limited Information The publicly available documentation does not cover edge cases in API configuration, credit consumption calculation, or sub-account permission structures in sufficient depth. Agencies attempting to implement complex integrations or multi-tier reseller models often need to escalate to support rather than resolving questions independently through self-serve documentation.

Who Uses Stammer?

Digital Marketing Agencies

Digital marketing agencies use Stammer to expand their service offering into AI chat without building proprietary technology. By white-labeling Stammer, they deliver branded AI chatbot products to clients as a managed service, creating a recurring revenue stream that complements their existing SEO, paid media, and content work.

AI and Automation Agencies

Specialist automation agencies use Stammer as the chatbot layer within broader workflow automation stacks that include tools like Zapier, Make, and HubSpot. The white-labeled API integrates Stammer's AI agents into multi-tool pipelines, allowing these agencies to offer end-to-end automation solutions with AI chat as one component.

E-commerce Platforms

E-commerce operators working with agencies deploy Stammer-powered chat agents for pre-sale product inquiries, order status follow-ups, and abandoned cart re-engagement sequences. The multi-channel capability — covering web chat and SMS — covers the communication touchpoints most relevant to online retail customer journeys.

Customer Support Services

Outsourced customer support providers use Stammer to automate tier-one inquiry handling for their clients, reducing the volume of conversations that require human agent involvement. The 24/7 availability of deployed AI agents allows support teams to manage higher client volumes without proportional headcount increases.

Uncommon Use Cases

Non-profit organizations have deployed Stammer-built chatbots for donor onboarding and recurring giving program management, using the appointment scheduling capability to book calls with major donor prospects. Event management companies use AI agents to handle venue inquiries, speaker submissions, and attendee scheduling at scale during high-traffic registration periods.

Final Verdict

Stammer is the most operationally complete choice for agencies building a chatbot reseller business — particularly for those needing sub-account separation and full API white-labeling without managing custom infrastructure. The primary limitation is cost scalability: high-volume agencies will see messaging credit costs compound as client conversation volumes grow, requiring careful margin planning.

FAQs

5 questions

Is Stammer suitable for small agencies with only a few clients?

Stammer's paid-only model means small agencies with fewer than three or four active chatbot clients may struggle to justify the monthly cost. The platform's ROI scales with client volume — agencies running five or more concurrent chatbot deployments will find the sub-account management and credit rollover system most economically efficient relative to the subscription cost.

How does Stammer compare to GoHighLevel for agency chatbot delivery?

GoHighLevel offers a broader agency platform covering CRM, email marketing, and funnel building alongside chatbot functionality. Stammer focuses exclusively on AI chatbot creation and white-label delivery, which means deeper chatbot configurability and a more refined reseller architecture. Agencies wanting an all-in-one platform often prefer GoHighLevel; those prioritizing chatbot depth and API control lean toward Stammer.

Can Stammer AI agents handle appointment scheduling without human involvement?

Yes. Stammer agents can be configured to present available time slots, capture booking details, and confirm appointments without human agent involvement. Integration with calendar tools like Calendly or Google Calendar through the API enables real-time availability checking. The scheduling workflow can be embedded in lead qualification sequences, so appointment booking happens within the same conversation flow.

What happens to unused messaging credits at the end of the month?

Stammer's credit system rolls over unused credits to the following month rather than expiring them. This protects agencies from losing paid capacity during quieter periods in a client's business cycle. The rollover model is particularly valuable for agencies managing seasonal businesses, where conversation volumes fluctuate significantly between peak and off-peak periods.

Does Stammer work for non-English speaking client markets?

Stammer AI agents support over 160 languages without requiring separate agent configurations per language. The model detects the user's language from the conversation and responds accordingly. Agencies serving international clients or managing chatbots for businesses with multilingual audiences do not need to build and maintain separate language-specific agents for each market.

Expert Verdict

Stammer is the most operationally complete choice for agencies building a chatbot reseller business — particularly for those needing sub-account separation and full API white-labeling without managing custom infrastructure. The primary limitation is cost scalability: high-volume agencies will see messaging credit costs compound as client conversation volumes grow, requiring careful margin planning.

Summary

Stammer is an AI Tool that gives agencies a complete white label infrastructure for building, branding, and reselling AI chatbot services. Its sub-account management, multilingual support, and white-labeled API address the core operational needs of agencies managing multiple client deployments simultaneously. The paid-only pricing model means agencies should evaluate it in the context of a committed client pipeline rather than exploratory use.

It is suitable for beginners as well as professionals who want to streamline their workflow and save time using advanced AI capabilities.
