Pinterest just rolled out another algorithm refresh prioritizing fresh visuals + keyword-smart descriptions. Google is indexing Idea Pins faster than ever. Yet most creators paste the same recycled caption into every pin.

Only three platforms delivered descriptions formatted exactly how Pinterest’s 2026 SEO guidelines recommend, and InVideo AI was the only tool that also generated board descriptions, Idea Pin scripts, and seasonal scheduling.

FAQs
Do I really need Pinterest-specific AI instead of generic ChatGPT prompts?
Generic prompts ignore crucial formatting: 500-character limit, keyword placement, affiliate disclosures, CTA style. InVideo AI’s Pinterest model was trained on 40k viral pins and respects every rule automatically.
Will InVideo AI work for Idea Pins or only static pins?
It covers both. You get slide-by-slide scripts, on-screen text, recommended audio vibes, and even email/newsletter repurpose blocks.
Can I add affiliate disclosures automatically?
Yes. Toggle “Affiliate / Sponsored” and MyMarky inserts FTC-compliant language (EN + ES) and automatically appends your unique tracking links or UTM codes.
