Frequently Asked Questions

No — you can generate Content Packs in any workspace (Snapshot, Video, Slideshow, Spotlight) 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. (The Snapshot workspace covers nine of the ten — every one except long-form YouTube, which needs an actual video, so it's only available in the Video and Spotlight workspaces. YouTube Shorts is available in the Snapshot, Video and Slideshow workspaces and in Spotlight's Get clients mode; Pinterest in the Snapshot and Spotlight workspaces; X and Bluesky are available in the Snapshot, Video and Spotlight 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 Spotlight (a quick business profile for a campaign, a podcast or YouTube episode in Episode mode, or one photo or video in Get clients mode). 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 promoting your photography business, with three modes. Campaign needs no photo or video: 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 one call to action — instead of personal storytelling. You can add the exact offer, a price, a real deadline and real proof (results, reviews, awards); posts use only what you enter there — never an invented price, deadline, review or fake urgency — and you can mark a post as an ad, gifted or a paid partnership so CAPTD labels it. CAPTD fits the call to action to each platform (link in bio on Instagram, a comment keyword on TikTok, the link in the first comment on LinkedIn, the link itself elsewhere) and adds UTM tags to your link so you can see which platform sent visitors — you can switch the tags off. Episode promotes a podcast or YouTube episode. Get clients writes a post from one photo or video so it brings enquiries. You can add optional typed text or a voice note in every mode.

A caption goal next to "Tell the story", for a single photo, that writes posts meant to start a conversation. Pick one of five kinds: Which edit? (two edits of one photo — the caption asks followers to vote, with a poll sticker on Instagram and Facebook, a poll to post on X, LinkedIn and Threads, and a vote line on Bluesky, TikTok, YouTube Shorts and Pinterest, which have no poll for a photo post), Before and after (your edit next to the original), Ask for critique (one specific question about the photo), Question hook (ends with one real question people can answer) and Behind the shot (the story of the moment, with the camera details you choose to share). Which edit? and Before and after take an optional second photo so the caption can compare the two. Behind the shot shows the camera details read from your photo — edit or remove any of them before you generate; only what you leave is sent, nothing is stored, and the location is never read from the photo for it. Engage is available on every plan that has Snapshot, with the same platform caps, Creator Voice, hashtags and alt text as any pack.

A mode of the Spotlight workspace for posts meant to win paid work. Add one photo or video, plus your business details once (what you shoot, where you're based, whether you travel, how people book you, and anything to always mention) — they're saved, and you can edit or clear them at any time. The caption tells the moment first, then adds one line on what you offer that this photo shows, and CAPTD places your booking line itself: "link in bio" or "DM me" on Instagram, a comment keyword on TikTok ("Comment BOOK and I'll send you the link"), the link in the first comment on LinkedIn, your website, email or number on the other platforms, and the website in a Pin's own link field on Pinterest — with UTM tags on your website unless you switch them off. You can also say who your work is for and add real proof (reviews, results, awards), and mark a post as an ad, gifted or a paid partnership. Nothing about your business is invented — no prices, offers, dates, awards, reviews or client names except what you typed yourself. Get clients comes with the Spotlight workspace: Solo and Studio, or Pro with the Spotlight add-on.

Yes — in the Spotlight workspace's Episode mode. Upload MP3, M4A, WAV, AAC, OGG or WebM, up to 3 hours and 500 MB. You get a transcript with speaker labels and timestamps to correct (give each speaker their name, fix names and terms), then posts for seven platforms, an episode description, pull quotes, chapters, five title ideas, key takeaways, the resources mentioned, a guest bio, three to five clip moments with start and end times, and optional newsletter and blog drafts. You can download the transcript as TXT or SRT. It costs 1 pack for up to 60 minutes plus 1 for each extra hour started (1–3 packs), shown before you upload and charged only if the transcription works; the first pack you generate from the transcript is included. The audio is deleted as soon as it's transcribed. Only upload a recording you have the rights to and that everyone in it has agreed to.

Yes. In Episode mode you can record up to 30 minutes in the browser (keep the screen on; if the browser stops the recording you can keep what was recorded), import an episode from your podcast's RSS feed (pick one of the latest 20 — only a show you own or have the rights to), or upload a subtitle file (SRT, VTT or TXT, such as YouTube Studio's caption download). A recording or an import costs the same packs as an upload; subtitles need no transcription, so the pack costs 1 pack as usual. Subtitle files are read in your browser and never uploaded.

Yes, in Episode mode. Upload an MP4 or MOV and CAPTD takes the audio out in your browser — only the audio is uploaded for the transcript, never the video. Under the episode pack you can then make quote cards (images of the pull quotes), video clips of the suggested clip moments or any part up to 90 seconds (cropped to 9:16, 1:1 or 16:9, with captions), or audiograms from the audio (a waveform with captions). Clean audio evens out the loudness to the podcast standard and lowers background noise; you can turn it off. All of it is made in your browser and saved on your device — nothing is uploaded, and it needs a recent Chrome, Edge or Safari.

Correct the transcript (CAPTD can suggest speakers' names from introductions, for you to confirm), pick one of your saved templates for how each output should be written, and generate. Besides the posts, description and quotes you get chapters, title ideas, takeaways, resources, a guest bio, clip moments and a YouTube pack (description with YouTube-ready chapters, tags and a comment to pin). Afterwards you can translate the whole pack into another language in one click (pull quotes stay word for word as they were said, with the translation shown under each), and chat with the episode — up to 20 questions per pack, answered only from the transcript, with timestamps; any quote in an answer is checked against the transcript word for word. Each post gets one invitation to listen, fitted to its platform, with UTM tags on your episode link, and you can mark a sponsored episode so every post carries the label — with the sponsor's name when the episode itself names it ("Paid partnership with …").

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 without re-encoding. Either way, all metadata (including GPS location) is removed before anything is uploaded.

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 Spotlight workspace — Campaign, Episode and Get clients modes — is bundled free with Solo and Studio, and available on Pro as the Spotlight add-on (+€4.99 one-time, 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 and Starter get one taste generation per account, once only.

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.

Only if you let it. If your photo contains location data, CAPTD turns it into a nearby place name on your device, using an offline city list — the coordinates never leave your device and are never stored. The place is only used if you tap Use. Without location data, our AI looks at the uploaded photo (metadata already removed) for a well-known landmark or city and offers it as "Recognised from the photo"; that's a guess, it's only used if you tap Use, and CAPTD never identifies people. All metadata is removed before a photo is uploaded, and you can turn suggestions off with "Suggest places from my photos".

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.

Yes — see our full Privacy Policy for details on data handling, third-party services, and your rights under GDPR.
