Generates 3-10 caption variants per Instagram post type (feed photo, carousel, Reel, Story, IGTV / long-form video) — each with a HOOK (first 125 chars before the "...more" cut), 20-30 mixed-volume hashtags split into niche / medium / broad / branded buckets, optional alt-text for accessibility, optional best-time-to-post hint, and an emoji-density toggle. Each variant uses a distinct angle (story / question / claim / list / personal) so you can A/B which voice converts.
Later starts at $25/mo. Buffer is $6-12/mo per channel. Hootsuite runs $99-249/mo. Jasper ($49-125/user/mo) and Copy.ai ($49+/mo) have IG caption templates buried inside larger writing suites. All four are scheduling tools with caption generation as a side feature. Free.ai is purpose-built for caption craft (post-type-aware system prompts, hashtag-volume mixing, hook-first focus, alt-text). Free.
Yes — Qwen 3 30B on our GPUs. 5 short captions with hashtags costs about 600 tokens. Free signup gets 10,000 tokens — ~16 sessions. Premium models (Claude Sonnet, GPT-5) write punchier hooks worth the swap when you're paying for a paid social campaign.
(1) Feed photo — main grid post, hook matters because of 125-char cut. (2) Carousel — 2-10 swipeable slides, treat as Twitter-thread-on-IG with swipe cues. (3) Reel — short vertical video, caption mirrors video hook + may mention trending audio. (4) Story — 24-hour content, micro captions with sticker suggestions (poll / question / quiz / countdown / slider). (5) IGTV / long-form — caption acts as video description with timestamps + why-watch hook.
Default 20-30 hashtags split into 4 buckets: 8-10 NICHE (under 50K posts — best discovery), 8-10 MEDIUM (50K-1M — sustainable reach), 4-6 BROAD (1M-10M — competitive), 2-3 BRANDED (your tag if applicable). Mixed-volume strategy outperforms all-broad or all-niche per Hootsuite's 2024 hashtag report. Toggle hashtags off if you put them in the first comment.
Instagram's accessibility feature for screen-reader users (blind / low-vision audience plus 7-13% of users who can't see images on slow connections). Required for inclusive content + good IG SEO ranking. Toggled on by default. The model writes literal what-is-in-the-image alt-text, not vibe descriptions.
No — banned phrases include 'Drop a 🔥 if you agree', 'Double tap if', 'Tap that follow button', and other engagement-bait. The model picks softer CTAs (comment / save / share / DM / tag a friend / link in bio) that don't get demoted by Instagram's anti-engagement-bait algorithm.
The first 125 characters of your caption — what readers see before the "...more" truncation. Captions that hook in those 125 chars get 5-8x more "tap to expand" rate per Buffer's 2024 data. Each variant lists its hook explicitly so you can compare which one survives the cut best.
No — first session free. Sign up for 10K tokens, generation history, premium models. ~16 sessions per signup grant.
Yes — describe your post in Portuguese, Hindi, Japanese, Arabic, Spanish, etc. and captions return in the same language with regionally appropriate hashtags. Critical for non-English creator markets where Instagram penetration is highest (India, Brazil, Indonesia).
A/B testing rule from creator data: the same image with 5 different hook angles (story / question / claim / list / personal) shows 3-7x variance in saves and shares. The model is forced to vary so you don't ship 5 captions that all sound the same.
Yes — POST to /v1/chat/ with the IG caption system prompt (in template source). Useful for content-scheduling SaaS, agency client deliverables, or e-commerce platforms auto-generating product post copy. Bearer auth, monthly limits. Docs at /api/.
