Our verdict
Trellus is a clever embedded dialer and real-time coach that lives inside your existing sales engagement tool, with a free tier and a low entry price. The catch is that it is still per-seat with opaque credit add-ons, leans on parallel dialing for its premium tier, and depends on a host platform. Dialfyne is a standalone, usage-based platform: reps are free, the dialer is power-not-parallel, and platform email plus AI roleplay share the same credit balance, all drivable from Claude or ChatGPT.
FAQ
Trellus has a free tier and per-seat paid plans, plus credit add-ons whose real cost is often demo-gated, so what you actually pay can be hard to pin down up front. Dialfyne is usage-based with reps free and one shared credit pool, and the pricing is published.
Trellus offers both, and markets parallel as its premium tier. Dialfyne is a power dialer by design, keeping a human on every call for conversion quality and compliance.
If you want a standalone, usage-based platform instead of a per-seat extension, Dialfyne is the closest fit, with a power dialer, platform email, and AI roleplay in one place. See our Trellus alternative page.
Dialfyne is a standalone platform rather than an in-SEP extension, and it connects to HubSpot and Pipedrive natively plus any tool over MCP, so your assistant can build lists and launch campaigns directly.
