How to Use AI to Come Up with TikTok and Reels Ideas

Short videos reward consistency, and consistency needs ideas. Most creators hit the same wall: a good week of posting, then a blank screen and the feeling that everything has already been done. The trick isn’t more inspiration; it’s a simple system that turns what you know into a steady flow of video ideas.

AI is brilliant at the brainstorming half of that system. It can help you define a handful of content pillars, generate dozens of angles, write punchy hooks and sketch quick shot lists. What it can’t do is film you, give you a personality or know what’s trending this morning. That’s your job. This guide takes about an hour to set up, then twenty minutes a week.

What you’ll need

• A clear idea of your niche and who you’re making videos for
• A phone with a decent camera and some natural light
• Your TikTok or Instagram account and its analytics
• A notes app or spreadsheet for your idea bank
• An AI chatbot and about an hour

Step-by-step: plan TikTok and Reels ideas with AI

1. Define your pillars. Pillars are three to five themes you’ll keep coming back to, such as tips, behind the scenes, mistakes and stories. Ask the AI to suggest pillars for your niche (prompt 1).
2. Generate a big idea bank. For each pillar, ask for 20 specific video ideas. Specific beats general: “three mistakes I made with my first sourdough” works better than “baking tips”.
3. Write hooks first. The first second or two decides whether people keep watching. Ask the AI for several hooks per idea (prompt 2) and say them out loud to see which sound natural.
4. Check trends yourself. Scroll the app’s own trending sounds and formats. Ask the AI how to adapt a trend you’ve spotted to your niche, rather than asking it what’s trending.
5. Script quickly. For each chosen idea, ask for a 30-second outline with on-screen text and a shot list (prompt 3). Keep it loose so you sound like you.
6. Batch film. Film four or five videos in one session, changing tops or backgrounds between them if you like. Editing is easier when you’ve planned the shots.
7. Review every week. Note views, watch time, shares and comments. Paste the numbers into the chat and ask what patterns stand out (prompt 4).

Copy-paste prompts

1. Find my content pillars

I make short videos about [NICHE] for [AUDIENCE]. I enjoy making [TYPES OF VIDEO], I'm comfortable [ON CAMERA / VOICEOVER ONLY / HANDS ONLY], and I can film [WHERE AND HOW OFTEN].
Suggest 5 content pillars for my account, each with a one-line description and 3 example video ideas. Make the ideas specific, not generic.

2. Hooks that stop the scroll

Here's my video idea: [IDEA]. My audience is [AUDIENCE].
Write 10 opening hooks under 12 words each, in different styles: a bold claim, a question, a mistake, a surprising number, a "watch me" and a relatable moment. Keep them honest; the video must deliver on the hook. Also suggest on-screen text for the first two seconds.

3. 30-second script and shot list

Turn this idea into a 30-second TikTok or Reel: [IDEA AND CHOSEN HOOK].
Give me: the hook, three short beats, a closing line or call to action, suggested on-screen text, and a simple shot list I can film on my phone. Write in a casual, spoken style with short sentences.

4. What’s working?

Here are my last [NUMBER] videos with topic, hook, length, views, average watch time, shares and comments: [PASTE DATA]
What patterns do you see in topics, hooks and length? Suggest 5 new ideas based on what's working, and 2 experiments to try next week.

Recommended tools

• ChatGPT: fast for idea banks and hook variations.
• Claude: good at turning rambling notes into tight scripts.
• Gemini: handy if you keep your idea bank in Google Sheets.
• Grok: useful for quick, punchy angles.
• CapCut or the in-app editor: for captions, cuts and text overlays.

Good short-form ideas often grow into bigger projects: you can plan a podcast episode around a topic that takes off, design YouTube thumbnails in Canva for longer versions, or write a newsletter people actually open to keep your followers coming back.

Tips and mistakes to avoid

• Don’t rely on AI for trends. Chatbots don’t know what’s trending today. Check inside the app.
• Sound like a person. Read AI scripts aloud and rewrite anything that sounds stiff.
• Deliver on the hook. Misleading hooks hurt watch time and trust.
• Use captions. Lots of people watch with the sound off.
• Credit and license properly. Use sounds from the app’s library and credit other creators when you stitch or remix.
• Label paid partnerships. Use the platform’s branded content tools when you’re paid or gifted.
• Keep an idea bank. Jot down ideas the moment you have them; AI is great for expanding a scribbled note.

FAQ

How often should I post short videos?

Post as often as you can keep up with without the quality falling apart. Three good videos a week usually beats seven rushed ones.

Can AI make the videos for me?

There are tools that generate video, but audiences respond to real people and real moments. Use AI for planning and scripting, and film yourself.

Should I post the same video on TikTok and Instagram?

Many creators do, but remove watermarks and adjust captions and hashtags for each platform.
