Instagram Caption, Carousel & Hashtag Engine

Build a full Instagram post: hook line, caption, carousel slide copy, alt text, and a researched hashtag set for any niche.

Act as an Instagram content strategist and caption editor for niche accounts that grow from saves and profile visits, not from dancing or giveaway bait. Build one complete post package: hook, caption, carousel, alt text, hashtags, and a follow-up content plan. Inputs: - Niche: [What the account is about] - Topic: [This post's idea] - Audience: [Who should stop scrolling] - Offer or CTA: [Follow / save / comment / DM keyword / link in bio / none] - Voice: [Direct / Warm / Witty / Expert] - Proof I can cite: [Metric, client result, or "none"] - Format mix: [Carousel is main / static is main, still write carousel] - Words I never use: [List, or "none"] Generate: 1. First-line hooks (5): Each under 8 words. These are the first line of the caption (and can double as cover text). Mix: specific claim, confession, open loop, numbered promise, blunt reframe. Mark the recommended one. No "Swipe to..." as a hook. 2. Caption (80-150 words): Open with the recommended hook as its own line. Then 1-2 short paragraphs. One concrete example or proof point (or a clear mechanism if Proof is "none"). White space. No hashtag dump in the body. End with one comment prompt that is answerable in a few words, plus the Offer or CTA if one exists. 3. 7-slide carousel copy: - Slide 1: Cover. Hook + 3-5 word subtitle. Promise what they will leave with. - Slides 2-6: One idea per slide. Max 28 words per slide. Headline + 2-4 supporting lines. Slide 4 or 5 should be the most saveable (framework, list, or before/after). - Slide 7: Recap in 3 bullets + CTA. Design notes: suggested layout (big type vs. photo + overlay), contrast, and what not to cram. 4. Alt text: One accessibility-first alt text for the cover (125-150 characters) that describes the visual and the topic, not "image of a carousel." 5. Hashtag set (research-style, 18 total): - Tier 1 (5): High-intent niche tags, likely 10k-500k posts if known, otherwise labeled as "niche-specific, verify volume." - Tier 2 (8): Mid-niche and adjacent community tags. - Tier 3 (5): Small, specific tags (location, method, audience identity). Format as a paste-ready block. If you are not sure a tag is real, omit it. Never invent a hashtag that sounds like a slogan. 6. First comment: Exact text to post immediately. Use it for the full hashtag block OR a leftover tip plus a question. Say which approach you chose and why. 7. Next 3 posts: Title, format (carousel / static / Reel), and one-line hook each, so this post is part of a sequence, not a one-off. Constraints: - No fake hashtags. No #Love, #InstaGood, #Motivation, #Success, #Viral. If a tag is guessed, mark it "verify" and prefer fewer tags. - Caption word count is 80-150. Count it. Do not pad with emojis. - Carousel slides are not a caption reprint. Each slide must stand alone in a screenshot. - Do not invent client results. If Proof is "none," use a process, teardown, or opinion with a qualifier. - Voice matches [Voice]. Sound like the account owner, not a social media agency.
