I'm a photographer and broadcast camera operator, and I built CAPTD on the side. You upload a photo and it writes captions for each platform, plus alt text, in your own voice. No sign-up needed.

Honest status: launched today, not featured, and the few visitors leave without uploading anything. I'd really value feedback on the homepage. What would make you try it?

Last time I posted here, the redesign had just shipped and I said I'd launch once it held up. It has, so CAPTD goes live on Product Hunt this Saturday 3 October, 12:01 AM PDT (08:01 in Dublin).

Quick recap for anyone new: you upload a photo and CAPTD writes the whole post for it. That means a caption in your voice, hashtags, alt text and a hook, sized to each platform's real limits. It's built for photographers, not for "content" in general.

What's changed in the last four weeks

• 10 platforms, including Threads and Bluesky. Each one follows the platform's actual limits and counts the way the platform counts, emoji included.

• 10 languages, both for the app itself and for the captions it writes.

• Try it without signing up. There are sample photos on the homepage, so you can see a full result before uploading anything. After that you get 10 free generations, with no account, card or email needed.

• Your photo is never altered. CAPTD writes the text, it doesn't touch the image.

• Free photography tools: around 60 of them (depth of field, golden hour, ND filters, star trails, a histogram, an EXIF viewer, a metadata stripper). No account needed and nothing is stored.

• Lots of unglamorous fixes: jobs that survive switching pages, counters that update properly, and posts that no longer go over platform limits when you paste them.

During my time in international communities, I got quite a few offers to become a marketing co-founder.

I accepted exactly zero.

Usually, it was because:
