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 replaces manual entry and spreadsheet validation with an end-to-end pipeline: capture the invoice, verify the extracted data, route it to the correct approver, and keep every step visible to the finance team. The platform leans on machine learning and LLM-driven OCR to read invoices accurately, including header information, line items, and tax details, for both vendor-based and service-based formats. Organization-defined rules then determine who approves what, so approvals move faster and comply with internal policy. A vendor portal lets suppliers submit invoices themselves and monitor status, which reduces back-and-forth. Serina is offered in several product tiers for different invoice types, from direct and utility invoices through PO-based matching and vendor self-service, plus a separate accounts receivable product. It integrates with leading ERP and payment systems and publishes a pricing calculator and demo booking for teams that want a tailored quote. The vendor lists a UAE focus alongside a US offering. **Pricing & Plans:** Serina is a paid B2B platform sold through several product tiers (Serina, Serina Plus, Serina 360, Serina Order Processing, and Zebo for accounts receivable). Public pricing is not listed on the site; the vendor provides a pricing calculator and demo booking for quotes. - **LLM-based OCR data capture:** LLM-driven OCR captures invoice headers, line items, and tax details automatically, cutting manual data entry on vendor-based and service-based invoices. - **Automated validation:** Automated rules check extracted data before it moves on, reducing the validation effort that typically consumes AP team hours. - **Workflow and approval routing:** Route invoices to the right approvers based on organization-defined rules, with visibility into each queue and workflow stage. - **Dashboards and spend analytics:** Interactive dashboards track outstanding payments, vendor activity, and financial data so finance leaders can act on real-time insight. - **Vendor portal and self-service:** Let suppliers upload invoices directly and track status in real time, reducing follow-up calls and streamlining vendor onboarding. **Strengths:** Automates capture, validation, and approval in one platform; LLM-driven OCR handles both direct and PO-based invoice formats; Vendor portal and self-service reduce manual follow-up; Dashboards give real-time visibility into invoices, POs, and payments **Limitations:** No public price list; buyers must request a quote; Most content and case studies focus on the UAE market; Best value requires integration with existing ERP and payment systems [Profile (Markdown)](https://openaitools.app/tool/serina.md) ## Frequently Asked Questions ### How do LightPDF and Serina compare in monthly traffic?
