About SEMrush

SEMrush is a global SaaS company and leading authority in SEO and marketing analytics. With millions of users across industries, their content strategy must combine reach, credibility, and velocity. To support new growth initiatives, SEMrush needed a leaner, faster way to create high-quality video content, without inflating creative headcount.

The challenge 

Daily, on-brand video content demands a lot: trend analysis, scripting, visuals, editing, analytics, and scheduling. SEMrush needed a way to scale this cycle across channels without the cost, delay, or inconsistency of manual processes.

Our approach

We set out to eliminate manual delays in SEMrush’s content production, while keeping quality and brand voice fully intact.

One AI system = four traditional roles

We built an AI video agent that replaced:

  • Strategy
  • Scripting
  • Video editing
  • Performance analysis

All with one fully autonomous system.

Continuous trend scanning

The agent scans platforms daily to:

  • Detect trending topics
  • Analyze formats, hashtags, and timing
  • Identify what’s working in the recommendation feed

Content that builds itself

From scripts to visuals to final videos:

  • All assets are generated by AI
  • Every piece aligns with SEMrush’s tone and visual identity
  • AI avatars serve as the on-brand content face


Hands-free publishing

Using n8n and Google Sheets:

  • Videos are automatically scheduled and published
  • No manual uploads or approvals required
  • Filters and post logic are fully customizable

Learning and adapting in real time

After publishing, the system:

  • Tracks views, retention, clicks, sentiment
  • Clusters audience behavior
  • Optimizes next content batch automatically


Final outcome

A lean, fast-moving content engine that:

  • Delivers viral content consistently
  • Cuts production time drastically
  • Reduces cost per video
  • Performs like a full creative team, without the overhead
“Teamlex helped us test and validate content strategies at scale through automation. Their AI content engine delivered speed, precision, and insights, without the usual human bottlenecks.”
