5 captions across 10 vibes with tiered hashtag stacks and post-type awareness.
An Instagram caption generator turns your photo description or post topic into ready-to-post captions in the vibe you pick. The good ones include hashtags grouped by reach and adapt to the post type (feed, Reel, Story, carousel).
This generator returns 5 captions per batch across 10 vibes with tiered hashtag stacks (15-20 tags per batch) and 30+ language support. Free for 5 batches per day with no signup. Predis, Copy.ai, and Jasper start at $32 to $39 per month.
Type what the photo shows or what your post is about. One sentence is enough. Add the post type (feed, Reel, carousel, Story).
Witty, aesthetic, motivational, casual, professional, storytelling, vulnerable, sales-led, controversial, or Q&A.
5 ready-to-post captions in your vibe plus 15-20 tiered hashtags (high-volume, mid-volume, niche).
A mix of short hooks (under 80 chars), medium captions, and 1 long-form storytelling caption (up to 2,200 chars). Pick based on your post goal.
15-20 hashtags grouped by reach: high-volume (1M+), mid-volume (100K-1M), and niche (under 100K). Mix calibrated for your follower count.
Witty, aesthetic, motivational, casual, professional, storytelling, vulnerable, sales-led, controversial, Q&A. Same input, very different feels.
Pick emoji-heavy (Gen Z, lifestyle), light (1-2 per caption), or no emoji (B2B, finance). All emojis tested for cross-client rendering on iOS, Android, web.
Reel captions are tighter and hook-led (under 80 chars). Story captions are short and prompt-driven. Carousel captions structure around slide flow.
Spanish, German, French, Portuguese, Hindi, Arabic, Mandarin, Japanese, Korean, Italian, plus 22 more. Cultural idiom localized; not translated English.
Save your tone profile, signature phrases, and banned words. Every batch then writes in your voice. Free tier is one-shot.
We do not store the topics or photo descriptions you type. Sessions expire on browser close. Premium offers encrypted history.
Predis.ai caps free at 15 posts per month. Copy.ai starts at $36/month. We give you 25 captions every 5 days for free, no signup.
Every output uses caption patterns benchmarked against 100K+ high-engagement Instagram posts. We know which hook structures actually stop the scroll.
Each caption pre-tested against the 'see more' cutoff (125 chars on feed). Your hook always lands above the fold. Long captions structured for scrolling completion.
Run 50 brainstorms a day. Nothing accumulates. We do not train on your captions or topics. Privacy first by default.
Daily posts across feed, Reels, and Stories. The generator gives you fresh angles when you have run out of ideas. Vary the vibe weekly to keep your feed fresh.
You sell handmade products and post 3x a week. The generator handles caption-writing fatigue so you can focus on photographing, packaging, shipping.
You are growing an audience around your expertise. Storytelling and vulnerable vibes build connection. Sales-led vibe converts when you have something to sell.
Posting on behalf of 10 client accounts. Each account has its own voice. Premium brand voice profiles per account so the same generator writes 10 different ways.
You took a great photo on Sunday morning and have 4 minutes before posting. You need a caption that does not sound like every other 'sunday vibes' post.
You are launching a product and need a caption that sells without being cringe. Sales-led vibe with a soft CTA, not a hard pitch.
Your engagement dropped 30% in the last 6 weeks and you suspect your captions are too generic. You need to test 10 different vibes to find what your audience responds to.
You are running a Reel campaign and the captions need to be 80 chars or less so they fit the on-screen overlay. Short captions with high punch.
You posted a vulnerable share last week and got 5x your normal engagement. You want to replicate the structure without being repetitive.
Your brand voice is established but you write 5 posts a week and you are tired. You want a draft that reads like you, not like a generic AI.
