Writing AI
Writing AI helps with blog posts, marketing copy, emails, social content, scripts, and documentation. It is one of the highest-volume use cases for AI — which makes pricing especially important to get right.
Common use cases
- ✓Blog posts and articles
- ✓Marketing copy and ads
- ✓Email campaigns
- ✓Social media content
- ✓SEO content at scale
- ✓Technical documentation
Why cost matters here
Writing is often the highest-volume AI use case in an organisation. Content teams generating tens of thousands of words per week can spend hundreds of dollars per month on AI — or they can get the same output for $10–30/month by choosing the right model for their output volume.
