Social Media Prompts

Hooks, captions, hashtags, titles and thumbnails β€” AI prompts that do the thinking work behind posts that travel.

Most posts do not fail on the video or the photo β€” they fail on the first three seconds and the first line. These nine prompts attack exactly those pressure points: hooks that stop the scroll, captions that earn comments, titles and thumbnail words designed for a small phone screen, and reply banks that keep your comment section warm without eating your day.

Each prompt asks the AI for options, not one answer β€” ten hooks, five captions, twelve titles. That is deliberate: a creator's real skill is choosing, and ten decent options with two great ones hidden inside beats one mediocre 'final' answer every time.

How to use these prompts

1

Generate wide, then choose narrow

Ask for the full set of options, pick the strongest two, and test those. Never post the first option the AI gives you β€” it is statistically the most obvious one, and obvious does not stop thumbs.

2

Keep a swipe file of winners

When a hook or caption performs well, save the exact wording in a notes file with its view count. After a month you will own a personal formula book no generic list can match.

3

Stay honest at scale

Every prompt below bans fake claims on purpose. Clickbait that lies buys one video a spike and costs the channel its trust β€” the only asset that compounds.

The Social Media Prompts 9 prompts

TikTok Hook Generator

Ten scroll-stopping first-3-seconds hooks plus two full 30-second spoken scripts.

Best for Β· ChatGPT
Act as a viral TikTok scriptwriter. My niche is [niche] and this video is about [topic]. Write 10 scroll-stopping hooks for the first 3 seconds β€” each under 12 words β€” using curiosity, a bold claim, a common mistake, or a surprising number. No clickbait lies: every hook must be true to the video. Then pick the 2 strongest hooks and write the full 30-second spoken script for each one in simple everyday words I can say naturally on camera, and suggest one short on-screen text line for each script.

Tip: Say the hooks out loud before filming. If a hook cannot be spoken in one breath, it will not survive the first three seconds no matter how clever it reads.

Viral Caption Writer

Five caption options with a hook first line and a question that invites comments.

Best for Β· ChatGPT
Act as a social media copywriter. Write 5 caption options for a [platform] post about [describe the post, photo or video]. My audience is [who]. The tone should be [funny / emotional / professional]. Each caption must have: a strong first line that works as a hook on its own, 2–3 short lines of value or story, and one genuine question at the end that invites comments. Use emojis only where they add meaning, maximum 3 per caption. Keep every caption under 60 words and make all five clearly different from each other.

Tip: The closing question does the heavy lifting β€” comments are the strongest signal you can send the algorithm in the first hour. Never replace it with 'like and share'.

Hashtag Research Set

A balanced 15-tag set for your account size: large, medium and niche tags with sizes explained.

Best for Β· ChatGPT
Act as a social media growth analyst. My niche is [niche], my platform is [TikTok / Instagram], and my account has about [number] followers. Build a hashtag set for a post about [topic]: 3 large tags (over 1M posts), 5 medium tags (100K–1M posts), and 7 small niche tags (under 100K posts). For every tag, write its rough size and one short reason it fits my post. Then give me one ready-to-paste block of all 15 tags, and finish by warning me about any banned or spammy tags commonly used in this niche that I should avoid.

Tip: Small accounts grow on small tags. A post can top a 40K-post tag and get discovered; on a 50M-post tag it disappears in seconds. Keep the 3-5-7 balance.

YouTube Title Maker

Twelve honest, phone-readable title options in three styles, with the top 3 ranked.

Best for Β· ChatGPT
Act as a YouTube strategist who studies click-through rate. My video is about [topic] and it is aimed at [audience]. Write 12 title options, each under 55 characters: 4 curiosity-gap titles, 4 titles with numbers, and 4 direct how-to titles. Every title must be honest to what the video actually delivers β€” no fake claims, no results I do not show. Use one power word per title and keep the language easy to read on a small phone screen. Afterwards, rank your top 3 and explain in one line each why that title would earn the click.

Tip: Write the title before you finish editing. If none of the twelve excite you, the video's angle β€” not the title β€” is the problem, and it is cheaper to fix now.

Thumbnail Text Ideas

Ten 2–4 word thumbnail texts with expression and background-colour direction for each.

Best for Β· ChatGPT
Act as a YouTube thumbnail designer. The video topic is [topic] and the final title is [title]. Give me 10 thumbnail text options of 2–4 words each: huge, emotional, readable at tiny size, and NOT simply repeating the title. Use contrast and stakes (for example: 'I QUIT', 'BIG MISTAKE', '$0 VS $1,000', 'NOBODY KNOWS'). For each option, also suggest the facial expression the person in the thumbnail should make and one background colour that would stand out in a busy phone feed. End with your single strongest recommendation and why.

Tip: Shrink-test every option: zoom your thumbnail mock-up down to the size of a postage stamp. If you cannot read it there, real viewers on phones cannot either.

Comment-Reply Bank

Twenty-five copy-paste replies for praise, questions, trolls and jokes β€” warm, never rude back.

Best for Β· ChatGPT
Act as a friendly community manager for a [niche] page. Build me a reply bank I can copy and paste: 5 replies for praise comments, 5 for questions about price or how to buy, 5 for negative or rude comments (calm and classy β€” never insult back, never sound like a company), 5 for 'where are you from' and 'how can I contact you' questions, and 5 playful replies for joke comments. Keep every reply under 20 words, warm and human, and use [link] or [name] placeholders wherever I must fill in my own details.

Tip: Answer the first ten comments on every post personally, then switch to the bank. Early real replies start conversations; the bank keeps them going while you work.

Content Ideas for Any Niche

Twenty filmable content ideas for a solo creator with a phone and zero budget.

Best for Β· ChatGPT
Act as a content strategist. Give me 20 content ideas for a [niche] creator who films alone with a phone and has zero budget: 5 educational ideas, 5 story or personal ideas, 5 trends or challenges adapted to my niche, and 5 'mistakes and myths' ideas. For every idea write the working title, the hook line for the opening seconds, and one sentence explaining exactly how to film it. Mark with a star ⭐ the 5 ideas most likely to bring in NEW followers rather than entertain existing ones.

Tip: Film the starred five first, in one batch, on one day. Batch filming turns a month of 'what do I post?' stress into a single afternoon of work.

Story Poll Ideas (7 Days)

Fourteen story ideas β€” two per day for a week β€” built for taps, votes and replies.

Best for Β· ChatGPT
Act as a story-engagement expert for [Instagram / TikTok]. My niche is [niche]. Give me 14 story ideas β€” 2 per day for one week β€” designed to earn taps and replies: yes/no polls, this-or-that sliders, quizzes with one surprising correct answer, 'help me choose' questions, and honest behind-the-scenes moments. For each idea write: the exact on-screen question text (under 8 words), which sticker to use (poll, slider, quiz, question box), and what I should post next depending on which answer wins.

Tip: Always close the loop the next day: 'Yesterday 68% of you chose X β€” so today…' Followers who see their vote matter will vote again tomorrow.

Profile Bio Writer

Six bio options β€” three professional, three fun β€” each within the 150-character limit.

Best for Β· ChatGPT
Act as a personal-branding copywriter. Write 6 bio options for my [platform] profile. I am a [role / niche], I post about [topics], my audience is [who], and my goal is [followers / sales / community]. Every bio must fit within 150 characters and follow this structure: line 1 β€” who I help and how, line 2 β€” a proof point or a personality spark, line 3 β€” one clear call to action (for example 'DM me START' or 'New video every day'). Give me 3 professional versions and 3 fun versions. No hashtag stuffing, no cringe, no emojis in every line.

Tip: Your bio is a signpost, not a CV. If a stranger cannot tell in three seconds what they get by following you, rewrite line 1 before touching anything else.
