Can SallyAI write captions and hashtags automatically?

Yes — SallyAI automatically generates captions and hashtags optimized per platform, based on the content you're posting and your historical engagement data. Upload an image or paste a topic; SallyAI returns platform-specific copy with hashtag sets tailored to each network's conventions.

Caption generation

• Platform-aware — short and punchy for X (under 280 chars), longer for LinkedIn (1,300-2,000 chars sweet spot), visual-first for Instagram (caption supports the image)
• Brand-voice consistent — captions sound like you, drawn from your trained voice profile
• Hook-first structure — opening line designed to stop the scroll
• Multiple variants — generate 3-5 caption options to A/B test or pick from
• CTA-aware — includes calls-to-action that match your campaign goal (engagement, click, sign-up, share)

Hashtag generation

1. Volume-balanced sets — mix of high-volume (broad reach), mid-volume (target audience), and niche (community) tags
2. Per-platform conventions — Instagram (10-20 hashtags in comment), LinkedIn (3-5 in post), X (2-3 max), TikTok (3-7)
3. Banned-list aware — avoids shadow-banned, deprecated, or off-brand hashtags
4. Trending tag suggestions — surfaces relevant trending tags in your niche
5. Custom branded hashtag enforcement — your campaign or brand hashtags always included

Image and video caption assist

Drop an image into SallyAI and it can describe what's in the image, suggest a caption that complements (not just describes) the visual, and generate alt text for accessibility — all in one pass. For videos, paste the script or transcript and SallyAI extracts a hook, a body, and a closing CTA.

Continuous improvement

SallyAI learns from which captions and hashtag sets actually perform — engagement rate, save rate, click-through, comment quality. Over 30-60 days, the suggestions get sharper to your audience's behavior, not the average user's.

Caption and hashtag generation is included in SallyAI at $29/month on top of any MiOpsAI plan. Try it free.
