About Online Text Lab

Online Text Lab is a fast, privacy‑first collection of text tools for writers, students, developers, teachers, editors, and anyone who works with words. From quick fixes (case conversion, trimming, cleaning) to deeper analysis (readability, keyword density, word/character counts) and utilities for the web (URL tools, encoding/decoding), our mission is to make everyday text tasks simple, reliable, and safe—right in your browser.

Why we built it

Most “free” text utilities come with trade‑offs: rate limits, login walls, or server uploads you don’t want. Online Text Lab is different. Our tools run client‑side— which means your text stays on your device. You get instant performance, no file transfers, and peace of mind when you’re working with drafts, assignments, sensitive snippets, or code.

What makes us different

Privacy by design: We don’t upload the content you type or paste. Processing happens locally in your browser. Your tool preferences are stored using local storage on your device so you can pick up where you left off.
Useful, not flashy: Clear interfaces, keyboard‑friendly controls, and thoughtful defaults. We focus on practical outcomes—accurate counts, clean exports, and copy‑on‑click that just works.
Free and accessible: Tools are free to use. We pay close attention to accessibility (proper labels, color contrast, focus states) so more people can use them comfortably with keyboard and assistive tech.
Performance at scale: Even larger texts remain responsive thanks to incremental parsing and lightweight UI components.

Popular tools at a glance

Word Counter: Live words, characters (with/without spaces), sentences, paragraphs, reading/speaking time, keyword density.
Advanced Text Cleaner: Remove extra spaces, normalize punctuation, strip HTML/URLs, merge lines—then export clean text.
Readability Test Tool: Quick readability metrics to estimate effort and grade level.
URL Utilities: Parse, inspect, encode/decode, and clean tracking parameters (UTM, etc.).
Random Number Generator: Secure (crypto), seeded, pool/no‑repeat draws, CSV/JSON export.
Anagram Solver / Word Unscrambler: Dictionary matches, wildcards, filters, and per‑length groupings.

How we keep the lights on

Online Text Lab is supported by privacy‑respecting analytics and advertising. We use Google Analytics to understand which tools are helpful and where to improve, and Google AdSense to cover hosting and maintenance. We don’t sell your data, and we don’t transmit the text you work on to our servers. See our Privacy Policy for details and opt‑out links where applicable.

Our approach to quality

Each tool is built with careful validation and edge‑case handling (emoji, diacritics, unusual whitespace, mixed encodings). We prioritize accurate output and deterministic behavior. If a tool could produce ambiguous results (for example, different “word” definitions across platforms), we document the chosen rules and provide tips so you can compare results with Word, Google Docs, or CMS counters.

Roadmap

More export formats (CSV/JSON where relevant) and one‑click “copy results.”
Batch utilities for repetitive tasks and bulk conversions.
Additional developer tools (headers, JSON validators, encoders/decoders).
Deeper readability and tone helpers that remain 100% client‑side.

Built in Finland, used worldwide

Online Text Lab is created and maintained in Oulu, Finland. We keep things simple: ship useful improvements, fix the rough edges, and listen to feedback. If something could be faster, clearer, or more accurate, we want to hear it.
