Stammer AI Review 2026: Pricing, Agent Limits, Reviews and Convocore Compared

What Stammer AI is

Stammer sells chat and voice AI agents that agencies brand as their own. Agents run on a website embed, Instagram DMs, Messenger, WhatsApp, SMS, an API and custom channels; phone numbers run through a Twilio integration ^2,5. Stammer says it has 35,000+ live agents, 12 million+ conversations and 1,300+ agencies; these are its own figures ².

Billing to clients runs through a prepaid Agency Wallet. Clients fund sub-account wallets at prices you set, and Stammer says 100% of those funds go to you and it never takes a percentage of what you charge ^1,2.

Stammer pricing in 2026

We read Stammer's pricing page on 29 October 2026. Yearly billing saves 20%. Standard has a 7 day trial and Pro a 14 day trial, both with a card ¹.

• Some third-party reviews describe $197 and $497 Stammer plans. Stammer's own pricing page does not list them, so we do not use them.

How the bill grows with clients

Stammer limits agents; Convocore limits client accounts on the lower plan. The chart assumes each client runs one chat agent and one voice agent and leaves out usage, phone numbers and extra concurrent calls on both sides. Convocore's White Label plan covers 20 clients; above that, White Label Elite ($349) has unlimited clients.

Stammer vs Convocore

Convocore's White Label plan is $199 a month ($133 billed yearly) with unlimited agents, 20 client accounts, 3 phone numbers, 10 concurrent calls and $60 of monthly usage. Elite is $349 with unlimited clients, client self signup and 25 concurrent calls. Voice usage is a $0.02 a minute platform fee plus voice and model providers at cost ⁴.

Other Stammer alternatives

These platforms also let agencies resell AI agents. Prices come from each vendor's page on 29 October 2026.

Which to choose

Stay with or choose Stammer if you are starting with a handful of clients, mainly sell chat agents, and want the lowest entry price with a 14 day trial.

Choose Convocore if you expect more than about 10 clients, sell voice agents that need concurrent lines and phone numbers included, or want one flat fee to budget against. White Label is $199 a month; Elite at $349 adds SaaS mode and unlimited clients.

What the evidence does not show

• Stammer does not name its speech engine and we found no independent latency test.
• G2 and Capterra had no Stammer listing we could open.
• The cost chart leaves out usage, which depends on each client's volume and model choice.

Deciding between Stammer and Convocore

Count your clients and the agents each one runs, then price both. Under about 10 clients with one chat and one voice agent each, Stammer's plan fee is lower; above that, Convocore's flat White Label fee is. Then add expected voice minutes on each side.

Switching from Stammer AI to Convocore

Agencies usually leave Stammer.ai when per agent and per feature add-ons make delivery cost hard to forecast as the client list grows. Here is how to move from Stammer.ai to Convocore without a gap in coverage, what carries over, and what the overlap costs. You can build the agent and test it in chat on the Free plan before paying.

Steps

1. Export what you have in Stammer.ai. For each client, copy the agent prompts, knowledge base content and channel list, and note which numbers belong to which client.
2. Rebuild the agent in Convocore. Create an agent, paste your prompt and greeting, pick a voice, and rebuild each tool or function as a tool node or webhook. Keep the same names and fields so your downstream systems see the same data.
3. Load the knowledge base. Crawl your website or upload files (PDF, Word, TXT, Markdown, CSV, JSON or HTML). On Business the crawler refreshes weekly, and daily on White Label, so answers stay current without re-uploading.
4. Connect a phone number and channels. Start with call forwarding from one existing line so callers dial the same number. Then attach numbers properly: buy one inside Convocore, connect your own Twilio account, or bring your carrier over SIP trunking.
5. Run both side by side. Send one channel, one number or after hours traffic to Convocore for about 14 days while Stammer.ai handles the rest. Read transcripts daily and fix gaps in the prompt or knowledge base.
6. Cut over, then cancel. Move the rest of the traffic once quality matches your Stammer.ai baseline, keep Stammer.ai live for a few days as a fallback, then cancel or downgrade.

What transfers

Knowledge base

Transfers fully. Re-crawl the same URLs or upload the same files. Workspace limits are 25,000 documents on Pro, 100,000 on Business and 500,000 on White Label.

Prompts and instructions

Copy over as text. Remove Stammer.ai specific variable syntax and function names, then retest each tool call.

Phone numbers

Keep them. Numbers on Twilio connect through your own Twilio account; numbers on another carrier connect over SIP trunking or can be ported. Forward calls during a port so no calls drop.

Client accounts

Recreate each client as a sub-account. White Label includes 20 client sub-accounts and unlimited agents; White Label Elite has unlimited sub-accounts and client self-signup. Your branding and custom domain carry the same look, so clients see no change.

Integrations

Not copied automatically; reconnect them. Calendar and email integrations are on every paid plan, CRM integrations and live handoff start on Pro, and webhooks, the full REST API and MCP start on Business.

Conversation history

Stays in Stammer.ai. Export transcripts and recordings you need for records before you cancel. Convocore logs every conversation from the first day.

Timeline

Move 1 or 2 pilot clients in the first week, run them for 14 days, then move the rest in batches per niche using the pilot agents as templates.

Cost of running both

Expect one month of overlap while pilot clients run on both. White Label is $199 a month for 20 client sub-accounts, unlimited agents, 10 concurrent calls and $60 of monthly usage credit. Cancel Stammer.ai once the last batch of clients has moved.

Method and limits

• Facts come from pages we opened on 29 October 2026. Figures we only saw in search snippets or in competitor reviews are left out.
• Convocore's prices come from the pricing catalog. Convocore competes with Stammer, so it has a commercial interest. If you find an error, write to support@convocore.app.
