Powsoo is a drop-in widget that adds visual intake cards to AI voice platforms. When a user is on a voice call with your agent, Powsoo renders synced cards in the browser so users can tap-to-confirm emails, phone numbers, dates, and other intake fields instead of spelling them out.

How do I add Powsoo to my voice platform?

Create a widget in the Powsoo dashboard and connect your Retell account, then drop one web component and one versioned script tag into your site. You add powsoo_show_card as a custom function on your agent. Setup takes about 5 minutes.

Which voice platforms does Powsoo support?

Retell today. Vapi and ElevenLabs support are coming soon. SMS fallback works for traditional PSTN calls.

Can I customize the look of the cards?

Yes. Powsoo supports full theming via JS configuration: colors, fonts, border radius, spacing. For deeper control, use Powsoo Atoms (React components) to build your own UI.

Where does the data go after a user confirms?

Powsoo fires webhooks the moment a card is confirmed, with the field name, value, and call session ID. Drop the payload straight into your CRM, database, or backend.

Does Powsoo work for phone calls?

Pure phone calls (PSTN) don't have a screen, so Powsoo's web widget can't render directly. Instead, Powsoo offers an SMS fallback: when the agent needs to confirm an email or phone number, the caller gets a one-tap SMS link.

Is Powsoo HIPAA / GDPR compliant?

Powsoo is built with healthcare and EU customers in mind. We're SOC 2 Type II in progress and offer DPAs and BAAs on the Pro plan and above.

Retell vs ElevenLabs: AI voice agents compared

Updated 2026-07-14

Retell and ElevenLabs come at voice agents from different strengths. Retell is a purpose-built voice-agent platform aimed at English-first US phone use: it bundles the call pipeline, adds a visual flow builder, publishes SOC 2 and HIPAA on its pay-as-you-go plan, and charges by the minute from $0. ElevenLabs built its reputation on text-to-speech, and its ElevenAgents product extends that into full agents with 70+ languages, retrieval (RAG) built into every tier, and delivery over phone, WhatsApp, and web chat. ElevenLabs sells subscription tiers with a fixed bundle of agent minutes, from a free 15 minutes up to 12,375 minutes on Business, with extra minutes at $0.08. So the choice is compliance and fast English-first launch (Retell) against voice quality, language reach, and multi-channel delivery (ElevenLabs). Pricing verified July 2026.

Reach versus compliance

ElevenLabs leads where the call is not in English or where the voice itself sells the brand. Language detection across 70+ languages and native text-to-speech make it the stronger pick for international or voice-first deployments, and RAG in every tier means agents answer from your knowledge base without a bolt-on. It also reaches callers on WhatsApp and web chat, not just the phone.

Retell leads on the regulated, English-first US call. It publishes SOC 2 and HIPAA readiness on the pay-as-you-go plan and will sign a BAA, so a healthcare or finance team can go live without moving to an enterprise contract first. ElevenLabs does not detail agent compliance on its public pricing, so confirm that with its sales team for a regulated workload.

Which to choose

Choose Retell for an English-first US phone agent that needs compliance in place and a fast, builder-driven setup. Choose ElevenLabs when calls span languages, when voice quality is part of the product, or when you need WhatsApp and web alongside phone, and your volume fits one of its monthly minute bundles.

Neither shows a screen

Great voice does not fix a misheard email. On both platforms the caller speaks the value and the transcriber interprets it, so a single wrong character still slips through. Powsoo adds a synced on-screen card during the call: the caller taps the correct email, date, or number and a webhook returns it clean. It works on Retell and ElevenLabs alike.

Frequently asked questions

Is Retell or ElevenLabs better for non-English calls?

ElevenLabs. Its agents support 70+ languages with automatic language detection, and voice quality is its core strength. Retell is English-first and US-focused, so multilingual deployments favour ElevenLabs.

Which pricing model is more predictable?

ElevenLabs bundles a set number of agent minutes into each monthly tier, so cost is predictable when your volume fits the plan, with overage at $0.08/min. Retell is pure usage-based from $0, which suits variable or low volume where a fixed subscription would waste minutes.

Can I add on-screen confirmation to either?

Yes. Both are audio-only, but a visual layer such as Powsoo renders tap-to-confirm cards during the call on either platform, so callers confirm emails and numbers by sight.
