PDF to Text API

Extract text from PDF documents: the complete document text, the text of every page separately, the document metadata (page count, title, author, subject, keywords, creator, producer, creation and modification dates, PDF version, encryption and outline flags), and a full in-document search that returns the matching pages with hit counts and context snippets. Supply a PDF by public URL, base64 or a raw binary request body; only public http/https URLs are accepted and private or internal hosts are blocked. Pure server-side computation (pdf.js, no third-party upstream, no per-page cloud cost). Ideal for document indexing and search, data extraction and ETL, invoice and contract processing, archiving and content pipelines.

OCR API

Extract text from images with optical character recognition in eight languages (English, German, French, Spanish, Italian, Portuguese, Dutch and Turkish). Get the full recognised text with an average confidence score and word and line counts, or word-level results where every word carries its own confidence and bounding box for layout-aware processing. Supply an image by public URL, base64 or a raw binary request body; large images are downscaled automatically before recognition to keep responses fast, and a warm engine keeps latency low after start-up. Pure server-side computation (Tesseract, no third-party upstream, no per-call cloud cost). Ideal for digitising documents and receipts, reading text from photos and screenshots, accessibility, and data-entry automation.

Sudoku API

Generate, solve and validate Sudoku puzzles through a fast, fully-local API. Create fresh puzzles at four difficulty levels (easy, medium, hard, expert), each guaranteed to have exactly one solution, returned as both an 81-character string and a 9x9 grid alongside the full solution. Solve any valid puzzle with a backtracking engine that also reports whether the solution is unique, and validate a grid to detect rule conflicts and completeness. Inputs accept an 81-character string (0 or . for blanks) or a 9x9 array, by GET or JSON POST. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for puzzle apps and games, newspapers and printables, tutors and training-data generation.

Password API

A fast, fully-local password toolkit: generate cryptographically-secure random passwords (configurable length, character classes and exclude-similar), estimate password strength (entropy bits, a 0-4 score, character-class breakdown, common-password detection, an offline crack-time estimate and actionable feedback), and create memorable diceware-style passphrases. Built on Node crypto, no third-party upstream, and inputs are never logged — so responses are instant, private and always available. Ideal for signup and account flows, admin tools, password managers and security features.
