The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices. The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator. Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request. **Pricing & Plans:** Freemium.

It generates autonomous blog posts, guides, tutorials, and reference documentation, then organizes that material so it is legible to both traditional search engines and the large language models that increasingly answer developers' questions. The product sits at the intersection of an AI blog generator and an SEO/AI-discovery tool. Rather than writing one-off articles, Waldium is designed to maintain a living body of developer-facing content that supports product adoption and DevRel efforts, with analytics that show what is being found. Waldium is one of the products Structured Labs builds as part of its broader knowledge-infrastructure portfolio; the company is backed by investors including Y Combinator and General Catalyst.
