Put your own volume in. Watch the bill drop.

Drag to your monthly AI agent volume and compare MediaSFU infrastructure against published voice-agent platform rates.

Third-party figures are published list rates as of mid-2026 and vary with plan, bundling, and provider mix. All-in costs on bundled platforms are commonly higher once STT, LLM, TTS, and telephony are added — always model your own volume and provider mix.

Solution capsules

AI support that a team can actually run

Ask support a question as a customer, then see the same conversation land on the operator side.

One session, two surfaces, and a record of what happened.

Embed on your help centre, pricing page, or in-app support panel.

Customer · Support agent · Team lead

What you'll see happen
  1. Support is ready for the customer
  2. Customer asks a question
  3. Operator dashboard opens on the same session
  4. Operator responds, co-pilots, or takes over

Try it now

Ask as the customer. Watch the operator side.

Type what a customer would really send — "where is my order?" — then watch it land on the dashboard beside it.

Runs in this browser. Nothing is created until you press start.

The whole integration

That entire dashboard is one tag and a key

All six widget types install exactly this way. Build one in the dashboard, paste these four lines, and replace a single value. There is no SDK to learn, no build step, and no backend to stand up.

The operator console — live sessions, conversation replay, human takeover.
