Captions for a TikTok texting-story video
Separate the captions inside the video from the post caption below it, and write each for a different job: one for silent viewers, one for the first line of the post.
Try it: start from this sample
Two captions, two jobs
Captions inside the video are text that is part of the picture, useful for viewers who watch without sound. The post caption is the text under the video. Do not repeat one in the other. The in-video line says what the viewer is watching, the post caption tells them why to stay or what to do next.
A worked example from the sample: the in-video line is "Booking a dentist, apparently" and the post caption opens "She wanted a root canal. She got a cinnamon one." Two lines, two jobs, no overlap, and neither one spoils the final bubble.
Make the on-screen caption readable
Aim for text that can be read on a phone held at arm's length. Keep a caption to one or two lines and under about twelve words. In the sample, a caption like "Booking a dentist, apparently" works above the chat, because it adds context the first bubble does not. The Creator plan can add auto-generated captions and voiceover; edit the generated text before you export, because names get misspelled.
Write the post caption in the first line
Captions are limited in length, so the first line must carry the point. Try one sentence that teases the last bubble without spoiling it, for example "The bakery had the better offer." Then, on a second line, say that the story is fictional. Hashtags come last, and only a few.
Keep it clear of the buttons
These numbers are typical as of November 2026; check the platform's own help page. TikTok places its own caption at the bottom and its buttons on the right, so keep your burned-in text away from those edges.
Tips
- Put burned-in captions in the upper third, clear of the posting app.
- Use sentence case; capital letters slow reading down.
- Spell every character name the same way in video and post.
- Read the post caption aloud: if the first line is dull, rewrite it.
- End the post caption with a plain fiction label.
Questions
Do I need captions inside the video?
They are optional but useful. Many people watch with the sound off, and a short line of on-screen text tells them what the chat is about. The Creator plan can generate captions automatically for you to edit.
Should the caption give away the ending?
No. Tease the situation or the last line without revealing it. A caption that settles the question removes the reason to watch to the end.
How should I label a fictional story?
Use a plain phrase such as "Fictional story" or "Not an actual conversation" in the post caption. Short clips travel without context, so say it on every post, not just the first.
Can I write captions in another language?
Yes. The chat text can be in any language you type. Voiceover on the Creator plan supports English, Spanish, French, German, Italian, Portuguese, Polish and Hindi.
Use it for simulated, labelled content. ChatsRat makes mock-ups and fictional conversations for creators, designers and teachers. Do not use it to pass off a made-up conversation as a real one, to impersonate a real person, or as proof of anything. See the Acceptable Use policy.
