Text selection units.

Target exact character positions or a relative portion of text.

Index selection addresses exact positions; percentage selection addresses a share of the text. The first row emphasizes three characters while the second emphasizes half the line. Both strings and their selector units remain editable.

A prompt to start from

Use Tesseract. Create a restrained Bone comparison with two Denim number rows. In the first text layer, use an index selector from 0 to 3 to lift and darken exactly the first three characters. In the second, use a percentage selector from 0 to 0.5 to affect half of its ten characters. Label the two rows quietly at the left and introduce their selector amounts in sequence. Keep strings and range units explicit in the project.

Read the prompt

Set up Tesseract by Mirage so you can create editable designs, edit videos, and make motion graphics in this agent’s environment. Read https://github.com/mirage-hq/Tesseract and check the requirements for this local or hosted environment. If it is supported, follow the official plugin or skills installation guide, use its required runtime version, verify the download checksum, and confirm a short preview renders correctly. Then ask what I want to make and which brand references or source assets I have. Keep the editable project and source assets with the finished render.
