Frequently Asked Questions
What makes a great social media caption? ▼
Great captions hook the reader in the first line (before "see more"), match the brand voice, invite engagement (question, CTA), use relevant hashtags naturally, and are the right length for the platform. Instagram loves longer storytelling; Twitter demands brevity.
Do I need to upload an image? ▼
No — you can switch to "Describe It" mode and type what the image or post is about. The AI generates equally strong captions from a text description. Uploading an image lets the AI see visual details you might miss.
How many hashtags should I use? ▼
Instagram: 3–10 (recent data shows fewer performs better). LinkedIn: 3–5. Twitter/X: 1–2. TikTok: 4–6. Too many looks spammy. The AI tailors the hashtag count to the selected platform.
Can I use the captions directly? ▼
Yes — they are ready-to-post. We recommend a quick read-through to adjust anything that doesn't match your voice exactly, but they are designed to be used as-is or with minor tweaks.
Is this tool free? ▼
