Why Platform and Tone Matter

A caption that works on LinkedIn rarely works on TikTok. LinkedIn rewards concise, professional framing with a business takeaway; TikTok rewards short, punchy hooks that match the platform's fast-scroll culture. Selecting your platform before generating changes the caption's structure and hashtag style, not just the wording.

Write Captions From a Photo

Attach an image and the AI actually looks at it — the subject, setting, colors, and mood — and writes captions grounded in those specific details instead of generic filler. You can attach an image with or without a topic: with no topic, the AI builds the caption entirely from what it sees; with a topic, it blends your context with the image content. JPEG, PNG, WEBP, and GIF are supported up to 5MB.

Tips for Better Captions

Be descriptive:More context = better captions
Mention your audience:"for fitness beginners" improves targeting
Include your goal:"to drive sign-ups" shapes the CTA
Match tone to platform:"witty and playful" for TikTok, "bold and confident" for LinkedIn
