How it works
Open your manga panel
Use a manga panel you generated in YarnSaga, or upload your own manga artwork to the canvas editor.
Drop a narration box
Pick a caption box for narration, or add a speech balloon or thought bubble alongside it, and place it on the panel.
Type and position
Type your narration or inner-voice text, drag the box to the corner or edge where it reads best, and resize the lettering to fit. Done.
What you get
Narration caption boxes
Clean rectangular boxes with no tail for narration, scene-setting, time cues and a narrator's voice — the manga staple.
Inner-voice text
Use borderless caption text for a character's inner monologue, the way manga separates thought from spoken dialogue.
Speech and thought too
Add round speech balloons and cloud thought bubbles on the same panel — one editor covers all lettering.
Readable lettering
Comic-style fonts sized for legibility, so narration reads cleanly at any panel size.
Layered and editable
Boxes sit on their own layer over the art — reposition or rewrite them anytime without touching the panel.
Export ready
Boxes bake into the exported image and the published page — no separate file to merge.

Common questions
What is a manga narration box?
A narration box is a rectangular text box with no tail, used for narration, scene-setting, time cues, or a narrator's voice — distinct from a speech balloon, which points at a speaker. YarnSaga lets you drop caption boxes onto any manga panel and type your text inside them.
Can I add inner-voice or monologue text?
Yes. Use a borderless caption for a character's inner monologue, the way manga separates unspoken thought from spoken dialogue. You can also use a cloud thought bubble if you prefer that convention.
Can I add speech bubbles on the same panel?
Yes. The same editor includes round speech balloons and cloud thought bubbles, so you can mix narration boxes and dialogue on a single manga panel.
Does the text stay editable?
Yes. Each box lives on its own layer over the art, so you can rewrite the text, resize the lettering, or move the box at any time without affecting the panel underneath.
Is the narration box tool free?
Yes. Adding narration and caption boxes is part of the free plan — no watermark and no separate lettering tool to buy.
Can I add narration boxes to my own manga images?
Yes. Upload your own manga artwork to the canvas and drop narration boxes on it, exactly the way you would on an AI-generated panel.
