## Harold

Harold is built on a simple premise: most document tools extract text, but few make that text trustworthy. 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

## Knowt

Knowt is a study platform built around flashcards and AI study tools, and it markets itself as the leading free Quizlet alternative. Its pitch is consolidation: rather than juggling several apps, students upload their class materials once and get flashcards, notes, summaries, and practice tests generated in one place. Importing existing Quizlet sets takes a couple of clicks, including images and formatting.

The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go.

Knowt is free to use for core studying, with unlimited learn mode and free practice tests. It is widely adopted in education, with millions of students and teachers using it and a strong presence in AP exam preparation, alongside SAT and ACT resources and a Chrome extension for on-screen study.

**Pricing & Plans:** Knowt's core features are free: unlimited learn mode, free practice tests, flashcard creation, imports, and AI study tools with reasonable usage limits. Optional paid upgrades (Plus/Unlimited-style tiers) unlock higher AI generation limits and premium features. No credit card is required to start studying.

- **AI PDF Summarizer and Flashcards:** Upload up to 30 files and Kai instantly produces notes, flashcards, summaries, and practice resources from them.
- **Import and Lecture Recording:** Convert Quizlet, Kahoot, Wayground, and YouTube content, or record live lectures to generate notes and study sets.
- **Exam Predictor and Planner:** Upload class files to get a study plan and exam prediction that highlights what your professor emphasizes most.
- **Voice Tutoring and Podcasts:** Kai quizzes you by voice and can turn any note or flashcard into a podcast for study on the go.
- **Study Modes and Exam Prep:** Free learn mode, matching games, spaced repetition, and practice test rooms cover AP, ACT, and SAT prep.

**Strengths:** Free core with unlimited learn mode and practice tests; One-click Quizlet import preserves formatting and images; AI turns PDFs, slides, and lectures into study materials; Strong AP, SAT, and ACT prep resources plus a Chrome extension

**Limitations:** Some AI generation limits encourage upgrading to paid plans; Advanced study plans rely on accurate file uploads; Best experience requires creating an account to save materials
