How it works

Set the rules once. Onmark applies them every day, for every person on the team.

  1. Upload

    Add your brand guide PDF, logo files, fonts and a few past designs your team is proud of.

  2. Learn

    Onmark pulls your colours, type, logo rules, layouts and tone of voice into a Brand Profile that you review.

  3. Create

    Anyone types “Flyer for Friday’s 20% off sale” and gets three on-brand options to edit and export.

  4. Check

    Any design, from Canva, a freelancer or a phone, gets a Brand Score and a list of fixes before it goes out.
