Questions & Answers

As answered by people managing OpenScan and CAPTD.app.

How would you describe the primary audience of your product?

CAPTD.app's answer:

Photographers — from hobbyists building an audience to working professionals (wedding, portrait, landscape, and event photographers) who need to post consistently but find writing captions and hashtags a time-consuming distraction from actually shooting. Also freelance and small-business photographers who use the dedicated Marketing workspace to promote their own services, print sales, or upcoming shows.

What makes your product unique?

CAPTD.app's answer:

CAPTD is the only content pack generator built specifically for photographers, not creators in general. It understands photography-specific genres — wedding, portrait, landscape, street, wildlife, architecture, and more — and adapts tone accordingly, rather than producing the same generic caption regardless of what's in the frame. It also goes further than captions alone: every generation includes a caption, hook, hashtags, alt text, a voiceover script, and a matching audio suggestion, tailored per platform. It works with zero signup, and pairs content generation with a full suite of free photography calculators and planning tools most competitors don't offer at all

Why should a person choose your product over its competitors?

CAPTD.app's answer:

Most AI caption tools are built generically for any creator and treat photography like any other content category. CAPTD was built by a working photographer specifically for photographers, so it understands the difference between a wedding shot and a landscape shot, and writes accordingly. It also solves more of the actual workflow — hashtags, hooks, alt text, and audio suggestions in one generation, not just a caption — and includes a genuinely useful free tool suite (exposure calculators, golden hour planning, an AI shooting assistant) alongside the paid content generation, so there's real value even before someone becomes a paying customer.

What's the story behind your product?

CAPTD.app's answer:

CAPTD was built by a photographer with 25 years of experience as a television cameraman, who could compose a shot in half a second but consistently lost twenty minutes hunting for three lines of caption. After realizing this was a shared struggle — a 2026 industry survey found over half of photographers want help with social media, and nearly a third call it one of the most stressful parts of running their business — CAPTD was built to solve that specific gap: a tool that actually understands photography, not a generic AI writer repurposed for it

Which are the primary technologies used for building your product?

CAPTD.app's answer:

React, TypeScript, Vite, Supabase (database, auth, storage), Google Gemini (AI generation), Vercel (hosting), Resend (transactional email), and PostHog (privacy-respecting analytics)
