Write Instagram Reels captions for a Reel I am publishing. You are an experienced social editor who understands that the video carries the main action while the caption adds context, stakes, proof, or a clear next step. Use my natural voice and the facts I provide. Do not invent results, testimonials, personal stories, partnerships, prices, or claims about what the audience will achieve. Reel content and spoken words: [REEL DETAILS] Audience and what they care about: [AUDIENCE] My voice and examples of how I write: [VOICE EXAMPLES] Post goal: [POST GOAL] Required facts, offer details, or disclosure: [REQUIRED DETAILS]
Create six caption options, each 90 to 160 words. Use six distinct approaches: contrarian observation, practical takeaway, personal lesson, behind-the-scenes context, audience question, and direct invitation. Start each with a first line that makes sense before the “more” break and does not merely say “wait for it” or restate the first frame. For every option, include: - Caption text with short paragraphs suitable for mobile reading. - One primary call to action that matches my post goal: save, comment, share, follow, visit a link, or send a message. - A separate set of 3 to 8 relevant hashtags, mixing broad and specific terms; avoid irrelevant reach-bait tags. - Any disclosure wording needed for sponsorship, affiliate links, or a material claim. Do not use engagement bait such as “comment YES” unless it has a real purpose. Do not promise outcomes the Reel cannot support. Ask up to 3 clarifying questions only if a required input is missing. Before answering, check that the caption contributes information not already clear from the video and that the CTA is achievable without confusing viewers.
Fill in
| Placeholder | What to enter | Example |
|---|---|---|
| [REEL DETAILS] | Describe what appears in the Reel, the spoken words, and its key takeaway. | A 24-second Reel showing three before-and-after edits to a client onboarding email; voiceover explains that the subject line should state the customer’s next action. |
| [AUDIENCE] | Describe the people you want to reach and the problem or interest they share. | Freelance copywriters and small SaaS founders who write onboarding emails themselves. |
| [VOICE EXAMPLES] | Paste a few lines from past captions or describe your preferred tone and wording. | I write short, calm captions with concrete examples. I avoid hype and usually end with one useful question. |
| [POST GOAL] | State the single action you want viewers to take after watching. | Get people to save the post and download my free onboarding checklist through the link in bio. |
| [REQUIRED DETAILS] | List facts, URLs, prices, dates, disclosures, or phrases that must appear. | Mention that the checklist has 12 items; no affiliate or sponsorship disclosure is needed. |
How to use
- Paste the Reel’s transcript or a scene-by-scene description, because the caption should add to the video.
- Choose one caption approach that matches the post’s actual purpose instead of publishing all six as slight variants.
- Confirm every product detail, result, disclosure, and link direction before posting.
- Follow up with: “Make option 3 25% shorter, retain the first line, and replace the CTA with a question that invites useful comments.”
Variations
Short caption
Use this for a fast Reel where the visual already explains most of the point.
Write 10 short Instagram Reel captions, 25 to 55 words each, for [REEL DETAILS]. My audience is [AUDIENCE] and my voice is [VOICE]. Each caption must add one useful context point that the video does not explain, use a different opening line, and end with one appropriate CTA for [GOAL]. Add 3 to 5 specific hashtags beneath each option. Use only supported facts from [FACTS]. Do not use vague excitement, engagement bait, or claims of results. Check that every caption reads naturally on a phone and that no hashtag is unrelated to the Reel.
Product Reel
Use this for a Reel demonstrating a product, feature, or service.
Write five Instagram Reels captions for a product demonstration of [PRODUCT]. The video shows [DEMO DETAILS]. Address [AUDIENCE]’s likely concern about [OBJECTION] without making unsupported performance claims. Each caption should be 110 to 150 words and include: an opening line, a clear explanation of who the product is for, one factual feature or use case from [APPROVED FACTS], and a CTA to [CTA]. Include required disclosure from [DISCLOSURE] exactly if supplied. Flag any claim that needs evidence before publishing.
Series episode
Use this when the Reel belongs to an ongoing educational series.
Write a caption for episode [EPISODE NUMBER] of my Instagram Reel series about [SERIES TOPIC]. This episode teaches [EPISODE LESSON], and previous episodes covered [PREVIOUS TOPICS]. My audience is [AUDIENCE]. Produce one caption of 130 to 170 words that makes the episode understandable to a new viewer, connects it to the series without requiring them to watch earlier posts, and asks one informed question. Include a simple suggestion to save or follow only if it fits [GOAL]. Use facts from [SOURCE NOTES] only. Check that the caption does not repeat the narration line by line.
Tips
- Put the practical detail that makes the Reel worth saving in the caption, such as a checklist, exception, or exact example omitted from the edit.
- Use only one main CTA; asking viewers to save, comment, follow, click, and share in the same post weakens the decision.
- When a Reel contains a claim about money, health, performance, or results, state the conditions or source rather than letting an edited clip imply a universal outcome.
- Hashtags should describe the subject and community, not every broad category your account could fit into.
FAQ
How long should an Instagram Reel caption be?
Use the space needed to add value to the video. Short captions work for a self-explanatory visual; a teaching or product Reel may need a compact explanation and a clear next step.
Should captions repeat the Reel transcript?
No. Use the caption for context, a caveat, a written example, or a question the video does not cover.
Can AI create hashtags for my Reel?
Yes, but treat them as suggestions. Remove tags that are broad, misleading, banned, or unrelated to the actual content.
