A closer look
Give CapIO a topic, a description, or a photo — get a caption you'd actually post. In 11 languages, tuned to whatever platform you're writing for.
CapIO turns a rough idea into finished text — no blank cursor, no staring at your camera roll for inspiration.
Type what your post is about, or a rough description, and get caption options built from it.
Upload an image and let CapIO write around what's actually in the picture.
Write once for the feed you're actually posting to — CapIO shapes tone and length to fit it.
English, French, Spanish, German, Portuguese, Dutch, Japanese, Korean, Italian, Chinese, Russian.
Past generations are kept in your content history, so a good line is never lost in a scroll-back.
Playful, direct, poetic — choose how a post should sound, not only what it says.
Enter a topic, or describe what your post is about.
Optional — upload an image for the caption to be built around.
Tell CapIO where it's going and which language it should be written in.
Get caption options back, ready to paste and post.
Switch languages per post — CapIO doesn't just translate, it generates natively in each one.
