Searching for "Calls Bulk", "Callz AI", or "Kols AI"? It's Kolz.

You probably heard the name on a call, a podcast, or from a colleague — and the spelling didn't come with it. The product you're looking for is Kolz Bulk (K-O-L-Z), the AI bulk-calling platform by Kolz AI.

The name, all the ways people write it

Calls Bulk · Callz AI · Kols AI · Colz AI · Kolz — same product, one spelling: Kolz, at kolz.ai.

What Kolz Bulk actually does

  • Upload a spreadsheet of contacts (Excel or CSV)
  • Pick a pre-built AI sales persona — no coding, no APIs
  • The AI calls every lead, qualifies them, and returns your spreadsheet enriched with Hot/Warm/Cold scores, summaries, and recording links
  • $0.03/minute flat — no subscriptions, no seat licenses, no hidden fees. 100 free minutes to start, no credit card

There's a second product too: if you run a Shopify store, Kolz Winback calls your abandoned carts back for you.
