It provides tools for generating logos, business cards, social media graphics, and brand guides, with options for customization and various file formats for web and print use.

Brandmark offers a comprehensive suite of tools for logo design and brand identity creation, aligning well with the concept's focus on brand guideline and asset management. It provides centralized storage for various brand assets, an editable brand guide, and shareable links. The platform also includes features for organizing assets, handling logo variants, defining color palettes, and setting typography.

The 'See example assets' link clearly demonstrates a brand guide with various sections and downloadable assets.
