Harold extracts data from invoices, receipts, purchase orders and statements, then applies a rules engine to validate it — checking that totals match subtotals and VAT, that supplier IDs are correct and that every line item adds up — before push to your systems. The key differentiator is where Harold catches problems. Instead of silently passing half-extracted documents downstream, it flags or fixes issues at the point of entry. A supplier mapping feature lets you map document aliases to your internal supplier IDs once and reuse that mapping forever, and output templates let you shape the export to exactly what your ERP, finance team or Zapier flow expects. Harold connects via Zapier or a ready-to-import file, and supports newer and legacy ERPs including Sage, Pegasus, SYSPRO and WinMan, as well as spreadsheets and inbox ingestion. Pricing is simple and predictable with a £19/month Founder rate, a £29/month Standard plan, a £79/month Premium tier and an Enterprise option for high-volume processing. **Pricing & Plans:** Harold uses simple tiered subscriptions: a free start to train your first document, a limited Founder rate at £19/month, Standard at £29/month, Premium at £79/month and Enterprise at £149/month, each with set monthly extraction and automation limits. - **Document extraction:** AI pulls headers, totals, line items and references from invoices, receipts, purchase orders and statements into structured data. - **Rules validation engine:** IF checks, formulas and conditional logic catch wrong totals, missing fields and bad supplier IDs, or transform data on the fly. - **Supplier mapping:** Map any supplier alias on a document to your internal supplier ID once, and Harold applies it automatically from then on. - **Output templates:** Shape exports to match your ERP, finance team or Zapier flow with CSV, Excel, JSON and webhook output templates. - **ERP and Zapier integrations:** Connect via Zapier or a ready-to-import file to send clean data into new and legacy ERPs, accounting tools, Excel or Google Sheets. **Strengths:** Validates data before it reaches accounting systems, not just extracts it; Works with both modern and legacy ERPs plus spreadsheets and Zapier; Supplier mapping and reusable output templates cut repetitive setup; Live pricing and a free way to test with your own documents **Limitations:** Priced in GBP, which may not suit all international buyers; Document box and automation limits rise only with higher tiers; Setup requires training documents per supplier for best accuracy; No self-serve enterprise features without contacting sales [Profile (Markdown)](https://openaitools.app/tool/harold.md) ## LightPDF LightPDF positions itself as an all-in-one document workspace rather than a single-purpose converter. 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. A free plan covers basic PDF tools with a 10MB file cap; paid plans start around $5.99/month, with a yearly tier and a one-time lifetime option. AI features consume monthly credits that differ by plan. - **AI document agent and chat:** Upload a PDF and ask questions in natural language, follow up on details and see which passages the answers came from. A separate chat mode works with YouTube videos. - **Layout-preserving translation:** Translate whole documents, including scanned and image-based PDFs, into 20+ languages while keeping the original formatting and layout intact. - **AI data extraction to spreadsheets:** Convert invoices, receipts, bank statements and purchase orders into structured, editable Excel files automatically. - **Full PDF editing and conversion suite:** Edit text and images, OCR scanned pages, convert to and from Office formats, then merge, split, compress, watermark, sign and annotate. - **Cross-platform access:** One account works on web, Windows, Mac, iOS and Android, so documents and paid features follow you between devices. **Strengths:** Very broad toolkit that covers both everyday PDF chores and advanced AI document tasks; Free tier is usable for light jobs, and the paid plans are cheaper than many competing PDF editors; Layout-preserving translation and AI data extraction handle scanned documents that trip up simpler tools; One subscription covers five platforms, including desktop and mobile apps **Limitations:** Free plan caps files at 10MB and adds watermarks on some outputs; AI features run on a credit system, so heavy usage means top-ups or a higher tier; Advanced AI operations like text editing or logo removal consume credits quickly [Profile (Markdown)](https://openaitools.app/tool/lightpdf-com.md) ## Frequently Asked Questions ### How do Harold and LightPDF compare in monthly traffic?
