Switching from Stammer.ai
A Stammer.ai alternative with guardrails, traces and your own model key
Stammer.ai is built for reselling: its $99/month Pro White Label plan includes your own domain and resale billing. Rylvo is built for running client assistants you can defend — guardrails, human takeover, test-before-publish and a trace behind every answer — with 25 assistants on the $100/month Pro plan and your own model key at cost.
Rylvo and Stammer.ai, side by side
| Rylvo | Stammer.ai | |

Why teams switch
More assistants per plan
Pro covers 25 client assistants and 50 channels, so adding a client doesn't change your bill.
Answers you can explain
When a client asks “why did the bot say that?”, open the trace: the passages it used, the rules it applied, the tools it called.
Rules outside the prompt
Guardrails redact personal data and block unauthorised promises before a reply is sent — not just a line in a prompt.
Bring any model
Use the model each client needs through your own key. You pay the provider at cost.
What every Rylvo assistant comes with
Website → assistant in a minute
Paste a URL; Rylvo reads the pages and builds an assistant that answers from them. No API key needed to start.
Lead alerts
When a visitor leaves an email or phone number, the owner gets an email with what they asked, and the lead lands on the Leads page.
Guardrails
Personal data is redacted, promises the business never made are blocked, and a request for a person hands off straight away.
Human takeover
Operators can pause the assistant and reply in the conversation themselves (Pro).
Test before it goes live
Separate Test and Production, with test suites and releases, so a change is checked before customers see it.
A trace behind every answer
See the passages it used, the rules it applied, the tools it called and what the answer cost.
When Stammer.ai is the better choice
- You need a fully rebranded client dashboard on your own domain — Rylvo white-labels the widget, not the dashboard.
- You want resale billing to clients built in rather than invoicing them yourself.
Questions
- Can my clients log in?
- Yes, two ways: invite them to your workspace with a view-only role (they see every assistant in it), or run each client in their own workspace and connect it to yours with approved, role-scoped agency access. The dashboard is Rylvo-branded; the widget their customers see is not.
- How do I charge my clients?
- Invoice them directly at your own price. Rylvo bills you a flat plan, and model usage goes to your own provider account at cost, so your margin is yours to set.
