Project Font Pro handles font replacement inside After Effects. It can replace all fonts in a project at once or target just some of them using filters, so you can swap one font for another or change only a font's weight, size, color or alignment.
Searches can run across an entire project, specific comps or the active comp. The panel shows how many layers use each font and how many remain after filtering, lists the comp where a font appears, and lets you open that comp in one click. It can also find missing fonts and replace them all at once with a new font, and grab the style from an existing text layer to apply it to any font.
Version 1.4 added a compact UI, regex filters for layer names and easier font selection. Project Font Pro supports After Effects 2020 through 2026, and a demo video is available.
