Executive Summary

Many SMBs and creators — on the order of 20 million potential users — publish daily visual content but lack a reliable, scalable way to produce consistent captions and accurate alt-text, which wastes hours and creates accessibility and SEO risks. This problem is most acute for small marketing teams, agencies handling multiple clients, and creators who prefer batch workflows and need queued daily posts without sacrificing brand voice. You could build a SaaS that ingests image batches and CSV schedules to generate style-adapted captions, SEO-aware hashtags, and context-sensitive alt-text using modern vision‑language models, combined with bulk-editing, human-in-the-loop review, and one-click scheduling integrations to major platforms. Differentiators would include per-account style templates, confidence scores and edit suggestions for alt-text to support accessibility audits, and tiered pricing plus API access for agencies. The market is large and timely: roughly 20M SMBs/creators × $240 ACV gives a $4.8B addressable market, and internal metrics (market score 88/100, revenue potential 82/100) indicate strong demand and monetization potential. Rapid improvements in vision-language models and growing emphasis on accessibility and batch publishing create a narrow window to offer reliable automation that meaningfully reduces creator time per post. To win you must deliver measurable accuracy (aim for >90% alt-text acceptance in screen-reader tests), deep platform integrations, and workflow ergonomics that minimize manual fixes, while keeping privacy and predictable compute costs under control. Challenges include medium competition, edge-case image understanding, and potential legal/regulatory exposure around accessibility claims, so start with high-ROI verticals (e-commerce, accessibility-focused agencies) and validate a small adoption hypothesis (1–3%) before scaling.
