Editor Software

What Editor Software does

Editor Software (UK) Ltd is a privately held UK software company that develops StyleWriter 4, a Microsoft Word add-in that copy-edits documents into clear, plain English. The product runs a rule- and pattern-based NLP engine against a proprietary graded dictionary to flag passive verbs, jargon, spelling inconsistencies, and wordy phrasing, and to suggest plain-English rewrites; it also produces readability statistics and supports custom style rules. Three commercial editions are sold — Starter ($90), Standard ($150), and Professional ($190) — as one-time perpetual licenses, accompanied by a free 14-day trial, a free electronic writing course, and a House Style module for organizations.

The company serves a mixed base of individual writers, journalists, students, and academics alongside enterprise and government customers, with case-study logos including the City of Los Angeles, the Environmental Protection Agency, SNR Denton, Halifax-Bank of Scotland, the Parliamentary Health Service Ombudsman, and references to Fortune 500 use. Distribution is primarily direct-to-consumer via the editorsoftware.com e-commerce site using PayPal for payment and SoftwareKey for licensing, with a parallel direct enterprise motion for site licenses and educational/campus-wide deals. Marketing is content-led through the company blog, free writing guides, and the Clear Writing Club / Clear Writing Style sub-sites, supported by LinkedIn, Facebook, and Twitter.

Editor Software appears to be a small, founder-led, bootstrapped business. Nick Wright, the Director and designer of StyleWriter, conceived the product from his earlier work as a publications manager in the Australian civil service. The company holds no disclosed external funding, parent company, or acquisition activity, and has no public revenue or headcount disclosures. Geographic reach is concentrated in the UK, US, and Australia across English-speaking markets, and the product carries the endorsement of the UK's Plain Language Commission.

Broad incumbents

• Microsoft Editor: Microsoft Editor is built into Word and Microsoft 365 and is increasingly positioned as a comprehensive grammar and style assistant. As the platform owner, it represents a structural competitive threat to StyleWriter's Word add-in model.

Direct peers

• Antidote: Antidote is a comprehensive writing assistant offering grammar, style, and dictionaries integrated into a single tool, popular in professional and editorial contexts. It competes directly with StyleWriter on deep style and editorial analysis.
• ProWritingAid: ProWritingAid provides in-depth writing reports on style, readability, overused words, and sentence structure, with a similar paid-software model targeting professional and business writers. It is one of the closest direct competitors to StyleWriter in comprehensive copy-editing.
• Ginger Software: Ginger offers grammar checking, sentence rephrasing, and translation tools for individual and enterprise users. It overlaps with StyleWriter's proofreading and style-suggestion capabilities, particularly for non-native English writers.
• Grammarly: Grammarly is the leading AI-powered writing assistance platform offering grammar, spelling, style, and tone suggestions across web, desktop, and mobile surfaces. It directly competes with StyleWriter in copy-editing and plain English improvement for individual and enterprise users.
• WhiteSmoke: WhiteSmoke is a grammar, style, and spell checker sold as packaged software with similar perpetual/subscription pricing tiers. It competes head-to-head with StyleWriter's Starter/Standard/Professional editions.
• Hemingway Editor: Hemingway Editor highlights complex sentences, passive voice, and adverbs to promote clearer writing. It targets the same plain-English, readability-improvement use case as StyleWriter with a simpler, web/desktop tool.
• PerfectIt: PerfectIt is a Word-based proofreading plugin that enforces house style and consistency across long documents, used heavily by editors and publishers. It overlaps StyleWriter's House Style and consistency-audit capabilities for professional editors.

Emerging players

• Linguix: Linguix is an AI-based writing assistant offering grammar checks and style suggestions across web extensions and enterprise integrations. It represents an emerging AI-native competitor in the same copy-editing category as StyleWriter.
• Wordtune: Wordtune is an AI rewriting assistant that rewrites and rephrases sentences for clarity and tone. It competes with StyleWriter's plain-English rewriting functionality from an AI-native angle, particularly for professional and business writers.
