How to add text to a GIF without it jittering across frames

the short answer

To add text to a GIF with aigif, paste the GIF into the Chrome extension and describe the caption you want; instead of overlaying a static layer that jitters, it re-renders the text consistently across every frame, then you export.

Adding a caption to a GIF sounds trivial until you try it. Most tools paste a text layer on top, and because a GIF is moving, that text often jitters, drifts, or sits awkwardly over the action. The caption ends up looking bolted on.

aigif handles text as part of the GIF rather than a sticker over it. You describe the caption and it re-renders the GIF with the text baked in consistently. Here is how to do it.

Overlay vs. re-render

An overlay tool draws your text on a fixed layer above a moving image. It is quick, but the mismatch shows: the GIF moves and the text does not, so it reads as two separate things stuck together.

Re-rendering treats the caption as part of the frame. aigif applies the text across the GIF so it holds position and style consistently, which is why the result looks made rather than captioned.

Beyond a plain caption

Because you are describing the change, you are not limited to dropping a line of text in the centre. Ask for a specific tone, a placement, a style, or a rewrite of existing text, and keep adjusting the prompt until it reads exactly how you want.
