How to Switch from Stammer AI to Trillet

Let's be direct about the money first, because most migration guides get this backwards. Stammer AI's Agency plan is $197/month and includes 20+ voice agents with unlimited client resale, which is genuinely cheaper on base price than Trillet's $299/month Agency plan. If the lowest platform fee is your only decision criterion, Stammer wins that line item, and you should know it before reading another word.

Agencies still switch, and the reason is not base price, it is architecture. Stammer is a chat-first platform that added voice as a module, with voice minutes priced per third-party LLM. Trillet is a native voice-first platform that owns its own voice stack, runs at sub-1-second latency (averaging ~400ms), bills a flat $0.12/minute, and includes HIPAA, SOC 2 Type II, GDPR, and TCPA compliance on every plan. When voice is your primary revenue line, those differences compound. This guide covers what actually changes, what transfers, and how to move 5 to 10 clients in a weekend, without pretending the switch saves you money on the base fee.

What Stammer AI Does Well

An honest migration decision starts with what you would be giving up. Stammer is a mature white-label brand with real strengths, and pretending otherwise helps no one.

Cheaper base entry. At $197/month with 20+ voice agents and unlimited client resale, Stammer's Agency plan undercuts Trillet's $299 base by roughly $100/month. For a small agency counting every dollar of fixed cost, that is a real advantage.
Broad multi-model catalog. Stammer lets you pick the LLM behind each agent, with voice priced per model (roughly $0.11/minute for lighter models up to $0.17/minute for premium ones). Agencies that want to tune cost per client by swapping models value that flexibility.
Chat-first depth. Stammer was built as a chatbot platform first. If a large share of your offering is text-based website chat and CRM-embedded chat workflows, Stammer's chat tooling is more developed than a voice-native platform's, and it fits agencies whose clients live in chat and GoHighLevel-style workflows.

If chat is the core of your agency and voice is a minor add-on, Stammer may still be the better fit. The rest of this guide is for agencies where voice is the growth engine.

Why Agencies Move to a Voice-First Platform

Agencies migrating to a voice-first platform consistently cite the same reasons: they want native voice quality, predictable economics, and compliance they can sell into regulated verticals. Each one matters more as voice becomes the majority of agency revenue.

Native Voice Instead of Voice-as-a-Module

Stammer started as a chatbot platform, and voice was added on top of it, priced per third-party LLM. That is a reasonable architecture for a chat-led product, but it means voice roadmap items, latency work, and voice-specific features sit inside a chat platform's priorities.

Trillet is a native voice AI platform, not a wrapper. It owns and controls its own voice infrastructure end to end: one provider, one point of accountability, no upstream dependency to inherit outages or price hikes from. That ownership is what lets Trillet target sub-1-second responses (averaging around 400ms, well below the natural conversational pause threshold) so the call feels like a real receptionist rather than a laggy bot.

What to do: If more than half your agency revenue comes from voice agents, evaluate whether voice is the platform's core product or a secondary module. For the full picture on this distinction, see voice AI wrapper vs native platform and the white-label voice AI guide.

Flat, Predictable Per-Minute Pricing

Stammer's voice cost changes with the model you select, from roughly $0.11 to $0.17 per minute. That flexibility is a feature, but it also means your cost of goods shifts every time you change a model, and forecasting margin across a client book takes more work.

Trillet charges a flat $0.12/minute overage on both Studio and Agency plans, regardless of what runs under the hood, with 300 minutes included on the Agency plan and transferred-call minutes billed at just $0.05/minute. One rate, no model math. For agencies pricing client retainers, a predictable per-minute cost makes margin easy to model.

Unlimited Sub-Accounts on Agency

Trillet's Agency plan includes unlimited client workspaces, so growing from 15 to 50 clients does not add per-agent platform fees. Stammer's $197 Agency plan already includes 20+ voice agents (and additional voice agents are only +$5/month each beyond that), so most agencies will not hit add-on fees soon, but the ceiling is different: Trillet's unlimited model means the platform fee never grows with your client count.

Compliance Included on Every Plan

Trillet includes HIPAA, SOC 2 Type II, ISO 27001, GDPR, TCPA, ACMA, and DNCR compliance on every plan at no additional cost, and acts as the agency's compliance and infrastructure partner so you can pursue regulated deployments (healthcare, legal, financial services) that competitors cannot touch. Healthcare alone is one of the highest-value verticals for voice AI agencies, with retainers commonly running $500 to $1,000/month per client.

Before selling into a regulated vertical, verify any platform's current compliance posture, including Stammer's, against your clients' requirements. Trillet's advantage here is that the certifications are held by the platform and available to every agency plan, not gated behind an enterprise tier or a paid add-on.

Multi-Channel, Not Just Voice

Trillet handles voice, SMS, web chat, and email natively. That covers the follow-up and confirmation surfaces most receptionist and lead-response workflows need, under one white-label roof, so you are not stitching a separate tool onto every client.

Honest Cost Comparison: Stammer AI vs Trillet at 15 Clients

An agency running 15 voice-heavy clients should model the real numbers, including the part where Stammer's base is cheaper. The table below uses the correct comparable plans: Stammer's $197 Agency plan (its 20+ included voice agents cover 15 clients with no per-agent add-ons) versus Trillet's $299 Agency plan.

Cost Component	Stammer AI (Agency)	Trillet (Agency)
Base plan	$197/month	$299/month
Included voice agents	20+ (covers 15 clients)	Unlimited sub-accounts
Additional voice agents	+$5/month each beyond the included 20+	Included (unlimited)
Voice usage (3,000 min)	~$330 to $510 ($0.11 to $0.17/min by model)	$324 (300 min included, then flat $0.12/min)
Transferred-call minutes	Billed per model	$0.05/min
Estimated monthly total	~$527 to $707	~$623
Compliance	Verify current posture	HIPAA, SOC 2, GDPR, TCPA included
Latency	Chat-first, voice add-on	Native, sub-1s / ~400ms

The honest read: Stammer is cheaper on base ($197 versus $299), and if you run its lighter models it can also come out cheaper on total monthly cost. Trillet's case is not "cheaper," it is "predictable and native." You get one flat per-minute rate that does not change with the model, 300 included minutes, unlimited sub-accounts, native voice quality, and compliance on every plan. Whether that is worth roughly $100/month more on base depends on how much voice matters to your book.

What Transfers and What You Rebuild

Migration between any two voice AI platforms involves rebuilding some components. Knowing what carries over and what needs manual work prevents surprises and helps you estimate accurate timelines.

What You Keep

Client business information. Your clients' business names, phone numbers, addresses, service lists, pricing, hours, and FAQs all transfer. This is your data, not Stammer's. Export it or pull it from your CRM.

Call forwarding setup. Your clients' phones forward to whatever number you point them at. Switching the destination from a Stammer agent number to a Trillet agent number takes about 30 seconds per client. No carrier changes, no number porting, no downtime.

Client contracts and billing. Your client relationships, contracts, and billing arrangements are yours. The underlying platform is invisible to your clients when you are properly white-labeled.

Calendar connections. Both platforms connect to Google Calendar and Cal.com (which also covers Outlook). You reconnect the same accounts on Trillet.

What You Rebuild

Voice agent configurations. Agent personalities, scripts, greetings, and conversation flows need to be recreated. Trillet's website scraping can auto-build a trained agent from a client's website and reviews in minutes, so you are not starting from a blank page.

Knowledge bases. Stammer's knowledge base content does not export to a universal format. Copy the text into Trillet's knowledge base builder, or use Trillet's automatic website and review scraping to rebuild it faster than the original manual build.

Conversation histories. Past call transcripts and chat logs stay in Stammer. Export them before canceling if you need them for records. Going forward, Trillet provides call transcripts, summaries, and recordings.

Automations and integrations. Any workflows connected to Stammer triggers need to be reconnected on Trillet. GoHighLevel is Trillet's one native CRM integration, alongside native Google Calendar, Cal.com, and Stripe billing. Other tools (HubSpot, Salesforce, and more) connect via MCP (Model Context Protocol), the in-call API, and webhooks, plus Trillet's 500+ integration partners, which often replaces old Zapier workarounds.

Step-by-Step Migration: 5 to 10 Clients in a Weekend

A structured migration moves 5 to 10 clients from Stammer to Trillet in a single weekend without client-facing downtime. The key is parallel operation: both platforms run simultaneously until each agent is verified.

Step 1: Set Up Your Trillet Agency Account (Friday Evening, 30 Minutes)

Sign up for the Trillet Agency plan at $299/month. Configure your white-label settings: custom domain, logo, brand colors, and client dashboard branding. This is a one-time setup that applies to all future clients. If you are still comparing options, the white-label voice AI guide walks through how agencies structure pricing and onboarding.

Step 2: Create Sub-Accounts and Build Agents (Friday to Saturday, 15 to 20 Minutes per Client)

For each client, create a sub-account in Trillet's dashboard. Paste the client's website URL, and Trillet scrapes the site plus online reviews to auto-generate a trained voice agent. Review the generated knowledge base, adjust details, and add the custom FAQs or pricing specifics you had in Stammer. For 10 clients, budget roughly 3 hours, most of it review and refinement rather than setup.

Step 3: Configure Integrations (Saturday Morning, 10 Minutes per Client)

Reconnect each client's calendar (Google Calendar or Cal.com) and CRM. GoHighLevel connects natively; other systems connect through MCP, the API, or webhooks. Rebuild any Stammer automations as equivalent webhook or API triggers in Trillet.

Step 4: Test Each Agent (Saturday Afternoon, 5 to 10 Minutes per Client)

Call each Trillet agent from a test number. Verify it answers correctly, books against the right calendar, sends SMS follow-ups, and handles common questions. Confirm response latency feels natural (Trillet targets sub-1-second responses, averaging around 400ms). Test edge cases: questions outside the knowledge base, a full calendar, and callback requests.

Step 5: Switch Call Forwarding (Sunday Morning, 2 Minutes per Client)

Update each client's call forwarding destination from the Stammer agent number to the new Trillet agent number. This is a settings change on the client's phone, not a carrier change and not number porting. Calls start routing to Trillet immediately, with zero downtime because the forwarding switch is instant.

Step 6: Monitor the First 48 Hours (Sunday and Monday)

Watch the first calls come through on Trillet's dashboard. Review transcripts and summaries, confirm integrations fire, and close any knowledge base gaps real caller questions reveal.

Step 7: Cancel Stammer AI (After Verification)

Once every client is confirmed working on Trillet, cancel your Stammer subscription. Export any historical data you need first.

What Trillet Does Not Do (Honest Caveat)

Trillet is a voice-first platform spanning voice, SMS, web chat, and email. It is not a chat-first chatbot platform. If your agency sells text-based website chatbots as a core product and needs deep chatbot tooling under one dashboard, Stammer's chat-first architecture is more developed for that job, and you would either keep Stammer for chat or pair Trillet with a dedicated chat solution.

The decision comes down to your revenue mix. If voice is the growth engine and chat is a minor line, the move to a native voice platform makes operational and quality sense. If chat and voice split roughly evenly, weigh whether running Trillet for voice plus a separate chat tool beats Stammer's combined offering for your specific client base.

Frequently Asked Questions

How long does it take to migrate from Stammer AI to Trillet?

A single operator can migrate 5 to 10 clients in one weekend. The bottleneck is reviewing and refining each agent's knowledge base, not the platform setup. Trillet's website scraping builds a baseline agent in minutes, and call forwarding switches take about 30 seconds per client.

Is Trillet cheaper than Stammer AI?

Not on base price. Stammer's Agency plan is $197/month and Trillet's is $299/month, so Stammer is cheaper to start, and with its lighter models it can also be cheaper on total monthly cost. Trillet's value is a flat, predictable $0.12/minute rate, 300 included minutes, unlimited sub-accounts, native voice quality at sub-1-second latency, and compliance included on every plan. You are paying for architecture and predictability, not a lower sticker price.

Will my clients notice the switch?

If you are properly white-labeled on both platforms, clients see your brand, not the underlying technology, and the call forwarding change is invisible to their callers. Moving from a chat-first platform to a native voice platform, callers may notice faster, more natural responses.

Does Trillet offer a free trial like Stammer AI?

Trillet does not offer a free trial. Every plan comes with a 28-day money-back guarantee, no questions asked. You can run real client deployments for 28 days and get a full refund if it is not the right fit, which tests the platform against actual call volume rather than a synthetic demo.

Can I run both platforms simultaneously during migration?

Yes, and you should. Keep Stammer active while you build and test agents on Trillet. Only switch call forwarding once each agent is verified, and only cancel Stammer once all clients are confirmed working. Budget for one month of overlap cost.

What if I need both chat and voice agents?

Trillet handles voice, SMS, web chat, and email, but it is not a text-based website chatbot builder. If website chat is central to your offering, pair Trillet for voice with a dedicated chat platform, or weigh whether Stammer's combined chat-plus-voice approach still fits your client mix. Many agencies find voice generates higher-margin recurring revenue than chat and choose to specialize. For a fuller comparison, see how other agencies weigh Stammer AI against voice-first alternatives.

Updated for July 2026: corrected Stammer pricing ($197 Agency, +$5/voice agent, 20+ voice agents included), reframed the migration case around native voice quality rather than base price, and fixed Trillet's channels (voice, SMS, web chat, email), latency (sub-1s/~400ms), and integrations (GoHighLevel native; HubSpot and others via MCP, API, and webhooks).
