The short version
ElevenLabs makes the best AI voices on the market. Period. If your top priority is the most natural-sounding speech possible (for a flagship product launch, a branded cinematic experience, or a premium hospitality site), ElevenLabs Convai gets the nod.
Spelo wins on speed and reach. Most Spelo installs go from "found this on a Tuesday" to "voice live on the homepage" the same afternoon. The widget reads your existing pages and can navigate them while talking, which means you do not write knowledge bases, prompts, or tool wiring. You install, you watch the first conversation, you iterate.
When ElevenLabs Convai is the right call
- You need a specific cloned voice, such as a celebrity, founder, or brand persona.
- The voice itself is part of the product story (entertainment, audiobooks, gaming).
- You have engineering capacity to wire up tools and design conversation paths.
When Spelo is the right call
- You want voice on your website fast, with no flow design step.
- The agent needs to actually do things on the page (scroll, click, filter, fill).
- You sell, book, or qualify online and silent bouncing visitors are the bigger problem than voice fidelity.
- You want a free tier to test before committing budget.
Can you use both?
Some teams do. ElevenLabs handles the marketing video voice-overs and the in-app TTS. Spelo handles the conversational widget on the public website. The two never collide.
FAQ
Common questions, honest answers
Still curious? Email hello@spelo.ai . Usually a same-day reply.
Is Spelo an ElevenLabs Conversational AI alternative?
For website use, yes. ElevenLabs Conversational AI is a powerful platform: you build an agent, give it tools, and embed it. Spelo is a finished widget: you paste one script tag and the agent works because it reads your live website. Same end result on a website; very different time to ship.
Which has better voice quality?
ElevenLabs leads on voice synthesis itself; their voices are widely considered the most natural in the industry. Spelo uses OpenAI Realtime, which is excellent for conversational flow but has a smaller voice library. If voice quality is the deciding factor, ElevenLabs wins. If conversational responsiveness is, the gap closes; both feel natural in a real call.
How does pricing actually compare?
ElevenLabs charges by usage (audio minutes converted plus Convai costs). Spelo bundles minutes into flat plans starting at $29/mo, with a free tier that includes real conversational minutes. For a website with light voice usage, Spelo is dramatically cheaper. For a phone-volume contact center, ElevenLabs can be more economical at scale.
Can ElevenLabs Convai click around my page like Spelo can?
No. ElevenLabs Convai answers questions and can call your APIs as tools, but it does not scroll, highlight, or fill out forms on your live website. Spelo is built around the page itself: the agent reads your DOM in real time and can navigate, scroll, click, and prefill forms while it talks. That is the core feature difference.
Can I get ElevenLabs voices in Spelo?
Not out of the box today. Spelo standardizes on OpenAI Realtime voices to keep the audio path simple (browser ↔ OpenAI direct via WebRTC). If you need a specific cloned voice, an ElevenLabs Convai build is the more direct path.
Which is more secure?
Both are reasonable. Spelo never sees the audio; voice streams directly between the visitor browser and OpenAI over WebRTC, and our servers only mint short-lived tokens. ElevenLabs handles audio on their infrastructure. Pick based on which vendor you would rather have in your data flow.
Which one will rank in Google search?
That is the wrong question. Neither widget changes your SEO directly. What matters is whether your site converts the traffic Google sends. Spelo turns silent visitors into voice conversations and contacts; that is where the conversion lift comes from.
