| SolarDialer | Retell AI | |
|---|---|---|
| Setup time | Minutes: sign up, upload your leads, pick an industry. New accounts are reviewed before their first call. | You write the agent's prompt, pick its voice, speech recognition and model, connect phone numbers, and build the campaign logic around it. |
| Scripts ready for 51 industries | Ready for 51 industries: opening line, answers to objections, qualifying questions and rules, all editable. | You write and test the script yourself; any templates are starting points, not ready-made scripts per industry. |
| Compliance gate built in | Yes: before every call, the lead's calling hours in each of its time zones, holidays, attempt limits and the do-not-call list are checked. | Building blocks only: calling hours by time zone, holidays, attempt limits and do-not-call checks for an outbound campaign are generally yours to build. Check their docs for what's included. |
| Live transfer to your closer | Yes: your closer's phone rings, they hear a short briefing, then the lead joins. | Possible: a transfer you set up and test yourself. |
| Pricing model | 22¢ a minute on our phone lines (14¢ agent + 8¢ line), or 14¢ with your own carrier. Calls nobody answers are free. | Usage-based, per minute, depending on the model and voice you choose. |
| Contracts | None. Add credit, pay for the minutes used, stop any time. | Pay as you go, with enterprise agreements. |
