Choose the workflow that fits your team.

ElevenLabs is widely known as the top tool for voice cloning and realistic AI voices. However, it is mainly a voice creation tool used by content creators, game makers, and engineers building custom chatbots. Using ElevenLabs for a bulk cold calling campaign means you have to build the entire phone system yourself, from buying the phone numbers and connecting Twilio, to writing the code that tells the AI how to handle interruptions and questions.

Kolz AI acts as a ready-to-use ElevenLabs alternative specifically built for B2B sales teams and call centers. Instead of building software, you just upload an Excel list of contacts and hit launch. Kolz AI handles the entire process: dialing the numbers, managing the natural two-way conversation, and summarizing the lead's interest. You get professional, sales-ready AI voices right away without writing a single line of code.

ElevenLabs uses a credit-based monthly payment model. When you use their calling tools, the costs can go up quickly because you are paying top dollar for highly realistic voices on top of your own phone and AI costs. Trying to run large sales campaigns (like thousands of calls a day) through ElevenLabs can lead to confusing and high bills, often pushing the cost to over $0.12 per minute.

In contrast, Kolz AI offers a very clear pricing model: a flat $0.03 per minute. There are no monthly payments, no confusing credit systems, and no need to pay separately for a phone provider. By picking Kolz AI as your ElevenLabs alternative for cold calling, you get a clear, cheap rate that lets you grow your campaigns easily.

The core output of ElevenLabs is exceptional audio and raw transcription logs, which are perfect for creative applications but create friction for sales teams. Sales representatives need actionable data, not just audio files, to close deals.

Kolz AI bridges this gap by delivering an "Excel-In, Excel-Out" experience. When your Kolz AI campaign finishes, you receive your original uploaded spreadsheet back, but it is now fully enriched. Every contact row is appended with the Call Status, a Lead Score (Hot, Warm, or Cold), a brief AI-written summary of the conversation, and a link to the call recording. This allows your human team to instantly focus on following up with the most qualified opportunities.
