About Buno
We built Buno because resizing is not design.
The story
Every campaign we worked on had the same hidden cost. The idea took an hour. Turning it into every size took the rest of the day: moving logos, shrinking headlines, checking that nothing was hidden behind a Story button.
That work matters, but it's not creative. It's production. So we built Buno to do it: one master banner in, every platform-ready size out.
Buno isn't a scheduler and doesn't post for you. It does one job: making sure what you post looks right in every size, from a 1080 × 1920 Story to a 320 × 50 mobile banner.
What we believe
- 01
Your time is for ideas.
Software should handle the repetitive parts, like checking 37 sizes for hidden text.
- 02
Simple beats clever-but-confusing.
If you can write a post, you can use Buno. No design skills needed.
- 03
Every size deserves a real layout.
Stretched and cropped is not good enough. Buno rebuilds each size for its shape.
- 04
AI should fit your workflow.
Use the assistant you already like, such as Claude or Cursor. Buno does the production.
