A “prompt” on TikTok is basically a starter idea or instruction that tells people what kind of video to make or how to respond. It can be a built‑in TikTok feature (like “Add yours” prompts) or just a line of text/voice that gives viewers a clear challenge, question, or theme to follow.

What “prompt” means on TikTok

  • A prompt is a short cue that says “Do this in your video,” for example a question, challenge, or theme.
  • It can appear as text on screen, in the caption, as a sound/voiceover, or as an in‑app prompt like “Add yours.”
  • Other users respond to that prompt by making their own videos that follow the same instruction, often turning it into a mini‑trend.

Types of prompts you’ll see

  • Challenge prompts – Ask users to try a dance, transformation, or task (“Show your 2019 vs 2026 glow up”).
  • Question prompts – Invite opinions or stories (“What’s the cheapest thing you do that feels rich?”).
  • “Add yours” prompts – A TikTok feature where someone posts a specific theme, and others tap “Add yours” to add their own video to that thread.
  • Story / POV prompts – Lines that start a story or point of view, guiding how others should act or narrate in their own videos.

Why prompts matter and how they’re trending

Prompts make it easy for viewers to join in because they remove the “What should I post?” problem and give a ready‑made idea. A clear, specific prompt also creates a strong hook, which helps videos get attention in TikTok’s fast‑scroll feed and can turn into viral trends when lots of people respond to the same idea.

Example to make it concrete

Imagine a video text that says: “Add yours: Show the first clip from your 2020 camera roll.” That line is the prompt; everyone who responds posts their own first 2020 clip using the same prompt, and TikTok groups those responses together via the “Add yours” feature.
