Golden hour rarely waits.

Medium

Chasing the last light before it disappears — this is why I never skip sunset walks.

Long

There's something about golden hour that slows everything down. No filters, no editing. Just the moment as it was.

I used to spend 20 minutes per post thinking of captions. CaptionAI cuts that to 10 seconds. Literally the best tool I've added to my workflow this year.

The TikTok captions are scarily good. The viral hook optimization actually works — my last 3 videos blew up and I genuinely think the captions had something to do with it.

As a YouTuber, the SEO descriptions and auto-timestamps alone are worth the subscription. I've seen a real uptick in search-driven views since switching.

I manage content for 4 brands simultaneously. The bulk generate feature is a game changer — what used to take my team 3 hours now takes under 15 minutes.

The language support is incredible. I post in both English and Indonesian and the captions are always natural — never that weird machine-translated feeling.

CaptionAI supports photos (JPG, PNG, WEBP) and videos (MP4, MOV, WEBM) up to 200MB. For videos, our AI extracts frames and analyzes scene context — not just the thumbnail.

9 platforms: Instagram, TikTok, YouTube, Facebook, LinkedIn, X (Twitter), Pinterest, Threads, and Telegram. Each has its own formatting rules, character limits, hashtag strategy, and tone guidance built in — so captions are always platform-appropriate.

Casual, Humor, Raw, Relatable, Aesthetic, Storytelling, Educational, Trending, Viral, Hype, Motivational, Professional, Thought Leader, Luxury, and Sales. Each has a distinct writing style. You can also add a custom hint on top — like 'keep it short' or 'no emojis' — to fine-tune the result further.

Yes. All plans — including Free — support all 110 languages. English, Indonesian, Spanish, Japanese, Arabic, Hindi, and 104 more. No language restrictions based on plan.

Each generation uses one credit — photo or video. You get three caption lengths (short, medium, long) plus a full tiered hashtag set in a single generation. Credits reset monthly and do not carry over.

Yes. Cancel at any time from your account settings — no questions asked. You keep access until the end of your billing period.

API access and bulk generation are available on the All-in-One plan ($22/month). The API lets you integrate CaptionAI directly into your own tools and workflows using standard REST calls.
