IN THEIR WORDS

What creators actually say.

"I used to spend 20 minutes staring at a blank caption box. Now I pick one, tweak a word, post. My Sunday mornings are mine again."

THE POWER OF CAPGEN

Built for the scroll-first era.

Captioning used to be the chore after the photo. CapGen flips it: read the image, match the voice, match the feed, automatically.

01

One photo. Eight voices.

Writes a distinct caption for each network, matched in length, tone, hashtags and cadence.

FREQUENTLY ASKED

Answers, unprompted.

CapGen uses a vision-language model to read your photo (subject, mood, composition, lighting) and then writes a caption for each network that matches its voice, length and hashtag conventions.
Instagram, TikTok, Facebook, X (Twitter), Threads, WhatsApp, Snapchat, and LinkedIn. Each caption is tuned to the platform's native tone and character limits.
Yes. Portraits, food, landscapes, products, events, pets. CapGen handles them all, and the tone and hashtag strategy adapts to the subject.
Your photo is processed only to generate your captions, then stored in your account so it appears in your collections. Delete a generation and its image is removed; delete your account and everything goes. Nothing you upload is used to train AI models.
For most everyday photos, they land on the first try. You can regenerate any network's caption in one click, or set the tone and length before generating.
Yes. Set a tone, theme, or the tags you want in the controls, and CapGen leans into those cues while staying true to what is in the photo.
On any paid plan, yes. Save a signature or brand-voice note and CapGen applies it to every caption on your account.
