A private, local-first marketing + SEO system. Audit any site across 5 pillars, test whether AI engines cite you, then generate images, captions, hashtags, and structured long-form content with meta + schema baked in — without subscriptions, accounts, or data leaving your machine.
Generate stunning images, captions, and hashtags for your brand in seconds. Bring your own API keys — you only pay for what you use.
Start MarketOSPlug in your API keys. Pay providers directly. No markup, no middleman.
A professional marketing workspace for teams who care about quality, privacy, and efficiency.
Paste your website. Describe what you need. MarketOS generates images with captions and hashtags, or long-form written content across 0+ types — all matched to your brand voice.
Audit any site in under a minute. Score it across five pillars. Test whether ChatGPT, Perplexity, and Google AI Overviews actually cite your brand. Then generate content that fills the gaps — with meta tags, JSON-LD schema, FAQs, and a drop-in llms.txt already included.
Paste any URL. We score Technical health, On-page quality, GEO readiness, E-E-A-T, and Performance — with real Core Web Vitals pulled live from Google PageSpeed Insights (mobile + desktop).
The killer feature nobody else ships. We generate 8 real buyer-intent queries, run each through Gemini with Google Search grounding, and parse the sources. You see your AI visibility rate, the specific queries you missed, and which competitor domains dominated.
Follows your sitemap (with homepage-link fallback), audits up to 15 same-site pages in parallel, flags duplicate titles, thin pages, schema coverage gaps, noindex mistakes, broken anchors, missing hreflang — plus robots.txt, sitemap.xml, llms.txt, and security.txt validation.
Generate across 100+ content types — blog posts, AEO answer pages, pillar clusters, FAQs, case studies, email sequences. Every output includes an SEO pack: title tag, meta description, slug, TL;DR, FAQs, Article + FAQ JSON-LD, and internal-link suggestions.
100+ content types across 11 categories, tuned to your brand voice. Exportable to PDF, DOCX, or TXT. Every piece pairs with the audit above to cover the gaps it finds.
MarketOS reverses the SaaS model. We bring the intelligence to your device, not your data to our servers.
Plug in your own API keys from OpenAI, Google, or Anthropic. You pay them directly at cost. We add zero markup and see zero traffic.
Everything is stored locally on your device in a high-performance SQLite database. Your prompts, images, and strategies never leave your machine.
Buy it once, own it forever. Standard Windows/Mac software with no monthly subscriptions, no seat limits, and no recurring fees.
Visual marketing + SEO content + full privacy — in one workspace.
Both plans are 100% BYOK. Your license unlocks the software — the AI spend is all yours. Every image, audit, caption, and content call runs on your own provider keys and bills directly to your account. We never proxy, meter, or mark up AI usage.
