Frequently Asked Questions

No — you can generate Content Packs in any workspace (Snapshot, Video, Slideshow, Marketing) with no signup, no login, and no email required. Signing up is entirely optional and only unlocks one feature: History, which saves your generated Content Packs to your account so you can revisit them and access them across devices. If you never sign up, CAPTD works exactly the same for generation — you just won't have a saved history to look back on.

From the History page, sign up with an email and password, or continue with Google — whichever you use, any Content Packs you already generated anonymously carry over automatically onto the new account, nothing is lost or reset.

From the History page, use the "Already have an account? Log in" link below the sign-up options — it works with email/password or with Google, same as signing up.

Because social media is one of the biggest pain points in photography. According to Format's 2026 State of the Photography Industry survey, 56% of Format's surveyed photographers say they want help with social media, and 31% call it one of the most stressful parts of running their business. 60% of Format's surveyed photographers said AI could specifically help with social media planning — which is exactly where CAPTD comes in.

A caption, image-aware hashtags, a matching royalty-free music suggestion, a description, a platform-specific hook, alt text, and a voiceover script — tailored to your chosen tone, style, platform and language.

Instagram, TikTok, YouTube, YouTube Shorts, LinkedIn, Facebook, Pinterest, X (Twitter), Bluesky and Threads — each with output tailored to that platform's conventions, not one generic caption reused everywhere. (YouTube Shorts is available in the Snapshot, Video and Slideshow workspaces; Pinterest is only available in the Marketing workspace; YouTube — the long-form platform — needs an actual video, so it's only available in the Video and Marketing workspaces, not Snapshot or Slideshow; X and Bluesky are available in the Snapshot, Video and Marketing workspaces but not Slideshow, since neither has a native carousel format; Threads is available in every workspace. The Slideshow workspace supports Instagram, Facebook, TikTok, YouTube Shorts and Threads.)

English, Italian, Spanish, French, German, Portuguese, Japanese, Chinese (Simplified), and Russian. Everything in a Content Pack generates in your selected language.

CAPTD has 4 dedicated workspaces, each built around a different primary input: Snapshot (a photo, single or in a batch), Video (a video, up to 150 MB and 3 minutes — about 2 minutes of phone footage at default settings), Slideshow (2–10 photos and/or videos in order, for a connected per-slide caption), and Marketing (no photo or video — just a quick business profile). All 4 also accept optional typed text or a voice note as extra context on top of that primary input, and all produce the same kind of Content Pack, tailored to each workspace's format.

A dedicated workspace for photography businesses running paid campaigns — no photo or video needed. You fill in a 7-field business profile (target audience, product/service, campaign goal, key message, call to action, offer, brand tone), and CAPTD shifts every field toward promotion — benefit-led hooks and captions, buyer-relevant hashtags, and a standalone CTA line — instead of personal storytelling. You can still add optional typed text or a voice note on top of the profile.

A dedicated workspace for multi-slide posts: upload photos and/or videos in order and CAPTD writes one caption per slide, forming a connected story as people swipe, plus one overall caption for the whole post. Available on Instagram, Facebook, TikTok, YouTube Shorts and Threads, each with its own slide-count and photo/video rules — Instagram, Facebook and Threads allow 2–10 mixed photo-and-video slides; TikTok needs 4–10 photo-only slides; YouTube Shorts allows up to 10 photo-only slides. A Stories toggle is also available for Instagram, Facebook and TikTok (Threads has no Stories format), for shorter, more casual copy suited to a Stories post.

It follows each platform's own technical format. Instagram and Facebook's Content Publishing API and Threads' carousel posts all support mixing photos and videos within the same post, so we allow it on those three. TikTok's Photo Mode carousel and YouTube's image-carousel format are both photo-only at the platform level — there's no video slide to upload even if we wanted to support it — so CAPTD blocks video uploads for those two platforms rather than letting you build something that won't actually publish.

Yes. Every field in a Content Pack has its own Copy, Edit and Regenerate controls, so you can tweak just the hashtags or ask for a fresh caption without redoing the whole pack.

An optional feature that learns your natural speaking style from voiceover recordings you make in the app, then nudges future captions and scripts to sound more like you.

Yes — upload a video (up to 150 MB and 3 minutes — about 2 minutes of phone footage at default settings; on phones with 4 GB of memory or less the ceiling is 50 MB, under a minute at default settings) and CAPTD analyzes both what's shown on screen and any speech. It compresses the video in your browser before upload, so a shorter clip or a lower capture resolution is what makes a big file fit.

Yes, automatically, before upload. Photos are resized and re-encoded for the copy CAPTD analyzes — it never touches the original file on your device, so nothing you later post is affected. Videos are compressed the same way, except an MP4 that is already 32 MB or smaller, which is uploaded as it is.

Yes — Batch mode lets you upload several photos and generate a separate, independent Content Pack for each one, then export the results as a CSV.

A bundle of 4 extra tools for the Snapshot workspace. Multi-Version Generation writes 2-3 full alternative content packs per photo — not just a different caption, a genuinely different pack each time — so you can pick and mix the best hook, caption, hashtags and more from each version. Shooting Insights surfaces useful details straight from your photo's EXIF data, like moon phase, effective focal length, and long-exposure or night-shot detection. Saved Hashtag Banks let you save and reuse your own named hashtag sets instead of retyping them every time. And the Posting Plan suggests a simple weekly posting plan based on your own recent generation history. It's included free with Solo and Studio, and available on Creator and Pro as a +€6.99 one-time bundle (expires with your credits).

A separate set of tools at /tools for analysing your own photos — not part of Content Pack generation. All of its tools except three run entirely in your browser and are free and unlimited for everyone. The three exceptions (Composition Analysis, Scene Recognition and Editing Suggestions) use Google Gemini vision, are limited to 30 combined analyses per month, and are bundled with Creator and above (see below).

The browser-only tools are free and unlimited on every plan, including Free. The three AI-vision tools are bundled with Creator, Pro, Solo and Studio; they are not available on Free or Starter, and are not sold as a separate add-on.

Yes. The Free plan gives you 10 Content Packs for Instagram, for the lifetime of the account and with no account required — plus one Video and one Slideshow generation to try. Paid plans unlock more platforms, batch upload and more packs.

Starter, Creator and Pro are one-time purchases — buy a set number of Content Packs and use them whenever, within 6 months. Solo and Studio are subscriptions, billed monthly or annually, with a fresh pack allowance every billing month and every workspace and add-on feature included.

One-time Content Pack credits stay valid for 6 months from purchase, and unused credits expire at the end of that period. Subscriptions release a fresh monthly allowance for as long as you're subscribed — including on annual plans — and unused packs don't roll over into the next month.

The Marketing workspace is bundled free with Solo and Studio, and available on Pro as a +€4.99 one-time add-on (expires with your credits) — Free, Starter and Creator don't get it at all. Slideshow works differently — it's bundled free (no extra charge) with Creator, Pro, Solo and Studio plans; Free gets one taste generation, once only, and Starter doesn't include it at all.

Yes — cancel any time from the customer portal in your Lemon Squeezy receipt, or by emailing us. Cancellation stops the next renewal and takes effect at the end of the current billing period, with no pro-rata refund for unused time or unused packs within that period. One-time packs don't renew, so there's nothing to cancel. If you haven't used a single credit from a purchase, contact us within 14 days and we'll ask Lemon Squeezy to refund it in full.

No. We do not use your uploaded content to train AI models, and we do not sell your personal data to third parties.

They're used to generate your Content Pack, then automatically deleted within 90 days — you don't need to do anything. Your generated captions and text history stay available for as long as your session is active. Photos analysed by the AI Photography Assistant's Composition Analysis, Scene Recognition or Editing Suggestions tools are deleted immediately after that analysis, not kept for 90 days.

Yes — go to the Privacy Policy page and use the "Delete my data now" button under Your Rights Under GDPR. It immediately and permanently deletes every photo, video, generation, review and consent record tied to your session — no waiting, no email required.
