GuideGuide is a grids-and-guides plugin for Photoshop, Illustrator and Figma: create rows, columns and baseline grids, save reusable guide sets, and place guides based on canvas, artboard or selection.
Annual subscription (specific amount not published in available sources). 14-day free trial, no signup required. Free for students and teachers for the duration of their education/employment.
Designers doing precise grid-based layout work across multiple tools (Photoshop, Illustrator, Figma) who want consistent, reusable guide sets rather than manually placing guides each time.
Saved guide sets are reusable across projects and tools: set up a standard grid once and apply it consistently rather than rebuilding guides from scratch on every new file.
