AI personalization made easy: Use AI variables without an API key

Use AI for lead enrichment, segmentation, and automation directly in your sequence builder

Updated over a month ago

Heeeey lemlister!

lemlist just made it easier than ever to personalize and clean your lead data using the power of AI—without needing to connect your own OpenAI API key! 🚀

With our new credit-based system, you can now use AI variables straight from your sequence builder and add smart logic to automate actions like a pro.

Let’s break it down 👇


✨ What’s new with AI variables?

Before this update, using AI variables meant setting up an OpenAI account and connecting your API key. That could be tricky and time-consuming.

Now, AI variables work through lemlist credits, so you can:

  • Use AI without creating or connecting an API key

  • Add AI steps directly into your sequence builder

  • Create waterfall enrichments (chain multiple AI steps)

  • Apply conditions (like if/else) for smart automation

  • See exactly how many credits will be used before running steps


💡 How AI variables work

1. Using AI with credits

  • You’ll spend 1 credit per AI result

  • Credits are only used if a valid result is returned

  • No credits are used when there’s no meaningful response

  • You can still connect your own OpenAI API key if you prefer

  • All credit usage is tracked in your history

2. Adding AI steps in your sequence

You can now:

  • Enrich leads using AI directly in the sequence builder

  • Combine AI steps to create a waterfall flow

  • Use conditional logic to customize actions based on AI output

This makes your campaigns smarter and more targeted than ever!

3. Credit usage visibility

  • You’ll see how many credits each AI step needs

  • Before a step runs, you’ll get a cost preview

  • Your credit usage history is always available


✅ Why this update rocks

  • No API key required – Start enriching leads right away

  • Easy access – AI variables are built into sequences

  • Smart automation – Use AI with conditions and logic

  • Clear usage tracking – Know your credit spend in advance


Ready to enrich your campaigns with AI?

Just go to your sequence builder, add an AI step, and start automating with smarter data. 💡
