Textbuddy

Textbuddy is a web-based text analyzer and AI-powered editor designed for writers, editors, and content creators who prioritize clarity and conciseness. It combines traditional "plain language" proofreading with advanced AI rewriting to strip away complexity and improve readability.

Key capabilities include:

• Text analysis and highlighting for long sentences, complex words, keyword repetitions, formatting errors, plus passive voice, adverbs, filler words, and vague words (some checks are English-only).
• AI assistant (GPT-4-powered) to rewrite selected sentences or paragraphs into plain English, fix grammar, spelling, and punctuation, generate draft text, and run unlimited custom prompts.
• Writing support tools such as one-click synonyms, a built-in readability score, CEFR language levels, word and character counts, text statistics, and keyword lists.
• Multi-language support for more than 50 languages.
• Privacy-First Workflow: The platform does not save user content, and the AI is explicitly configured not to use submitted text for model training.

Pricing: Freemium — free version available without login; Premium at $9/month (billed yearly) or $19/month (billed monthly), includes unlimited GPT-4 with no credits or limits, 14-day money-back guarantee. Volume discounts available for 10+ licenses.

What makes it notable is its focus on plain-language editing paired with a GPT-4 rewriter, a strong privacy stance (content stays on your device, not saved or sold, AI will not use it for training), and enterprise-grade security (SOC 2 compliant, AES-256 encryption at rest, TLS 1.2+ in transit via the OpenAI GPT-4 Enterprise API).
