ProWritingAid vs Wordtune: pricing, features and which to choose

ProWritingAid began in London in 2013 after founder Chris Banks built software to help with a novel. The company says it remains independent and has taken no venture capital. It now says the service helps millions of creative and business writers around the world. Its stated audience includes novelists, business writers, teachers, students, and English-language learners. The product has expanded beyond spelling and grammar into a writer’s toolkit covering planning, drafting, line editing, story critique, and publishing preparation. Its central identity is a writing assistant that combines detailed diagnostics with story-focused feedback, while leaving decisions about revisions to the writer. The company presents storytelling, practice, and feedback as central to its approach.

A typical workflow can begin in the Web Editor, where users upload or paste a document, or through Desktop Everywhere for Windows or Mac. Browser extensions for Chrome, Edge, and Firefox provide access on websites and webpages, while integrations include Microsoft Word, Google Docs, Scrivener, Apple Notes, Notion, Apple Pages, and Atticus. Reports cover grammar, spelling, punctuation, style, readability, sentence structure, sentence length, repetition, consistency, clichés, dialogue, pacing, sensory detail, and word choice. Rephrase offers alternative wording, Word Explorer and Thesaurus support word selection, and customizable settings let users manage terminology and preferred rules. Story tools include Story Canvas, Chapter Critique, Manuscript Analysis, Plot Analysis, Character Analysis, Virtual Beta Reader, and Marketability Analysis.

ProWritingAid suits writers who want extensive manuscript diagnostics and story feedback, though its many reports can require time, interpretation, and editorial judgment. It is less suitable for people wanting only a minimal correction layer, a general-purpose text generator, or primary support for languages other than English. Grammarly is a closer editorial fit for everyday workplace correction, LanguageTool for multilingual checking, and AutoCrit for fiction-focused manuscript work. ProWritingAid says analyzed text is deleted after processing, except documents explicitly saved in its encrypted Web Editor, and says customer writing is not used to train its models. Its AI documentation also says users retain rights to their writing, while publishers, schools, contests, and clients may set their own AI-use rules. Pick it when report depth and story-level feedback matter most.

Wordtune is an AI writing assistant made by AI21 Labs Ltd, launched in 2020 as a browser extension. It later added summarization, mobile access, whole paragraph generation, and a dedicated web editor for longer work. The product remains accessible, but Israeli reporting in April 2025 said AI21 halted Wordtune development and left it in maintenance mode while shifting attention toward enterprise and business products. That distinction matters for buyers because Wordtune still covers rewriting and summarization, while its product direction appears less active than its feature set. AI21 remains the current owner as of October 22, 2026. No public user or funding total is attached to Wordtune itself, so its scale cannot be quantified from published company details.

Wordtune covers the common editing loop from rough sentence to finished passage. In the web editor, users can rewrite text, change tone, expand or shorten passages, correct grammar and spelling, summarize documents, ask AI questions, generate ideas, and continue writing from context. Its browser extension places inline suggestions inside text boxes and supports Gmail, Google Docs, Slack, and social or web applications. Users can work through Chrome, Edge, Firefox, Arc, or the iPhone app. Wordtune supports English rewriting and translation input from Spanish, Mandarin, Arabic, Hindi, Korean, Hebrew, Russian, German, French, and Portuguese into English. The workflow suits paragraph revisions, email polishing, and quick alternatives more than autonomous long form authorship.

Wordtune is strongest when the job is producing contextual phrasings, adjusting tone, or reshaping a paragraph inside the writing surface. Its maintenance mode reporting may concern buyers seeking active feature development, a published consumer model roadmap, self hosting, or a broad proofreading suite. QuillBot offers explicit paraphrasing modes such as Academic, Formal, Simple, Expand, and Shorten. ProWritingAid is another writing focused alternative with deeper style reports. Sudowrite, Novelcrafter, NovelAI, and Squibler are relevant writing alternatives with different documented scopes. Pick Wordtune for contextual rewriting and tone alternatives at a low annual entry price, provided its current development status fits your needs.
