European alternatives to Grammarly
Grammarly built a $13B valuation on Microsoft 365 integration and network effects, but European users pay for US-trained models, US-hosted servers by default, and a feature stack (brand tone, team workflows, SEO-style checking) that SMEs never use.
Grammarly's dominance is real: 30M+ users, enterprise deals with Fortune 500 companies, and flawless Word/Google Docs embedding. The product was engineered for marketing teams and agencies needing tone consistency and campaign copy analysis across 50+ team members. But that breadth creates bloat. An individual writer in Stockholm sees premium features (tone detection, plagiarism scanning, full-stack writing analysis) bundled into a $12/month subscription, with no option to disable the ones they don't want. The Grammarly business model—free tier driving consumer adoption, premium tier funding enterprise sales—means individual pricing never dropped below US-market rates. Data flows to US servers by default; EU data residency is not marketed as a feature. The company's privacy policy is clear (GDPR-compliant) but treats Europe as a secondary market, not the primary user.
EU alternatives split into two categories: focused grammar assistants (LanguageTool, Ludwig, Duden Mentor) and full-stack writing suites with team collaboration (DeepL Write, Writefull, Neuroflash, ProWritingAid). LanguageTool, the oldest player, went open-source and self-hostable, winning enterprises needing on-premise deployment and multilingual support across 30+ languages. DeepL Write, backed by Applike (Berlin), defaults all processing to EEA infrastructure and integrated into a trusted enterprise platform serving 200K+ businesses including 50% of Fortune 500—directly competing with Grammarly's feature-parity but with EU-first architecture. Writefull carved out academic writers, trained on millions of journal articles, winning researchers by never storing or training on their text. ProWritingAid owns individual writers: 4M+ users, privacy-first (text never trains models), and actionable analysis (sensory details, pacing, dialogue tags) that Grammarly bundles but doesn't emphasize.

Our honest take
LanguageTool wins teams and enterprises needing multilingual support, on-premise deployment, and full API access (30+ languages, self-hostable, open-source). DeepL Write wins marketing teams wanting EU data defaults, tone adjustment, and Fortune 500 legitimacy without the feature bloat. ProWritingAid wins individual writers and novelists: 4M+ users, deeper style analysis, zero text-training, and cheaper ($99/year vs. Grammarly's $144/year). Writefull wins academics: journal-trained feedback, institutional licensing, zero training on researcher text.
Språkmotor's honest position: it beats Grammarly on EU hosting (all processing on Swedish servers), pricing for individuals (free tier with no premium upsell pressure), and focus (an AI writing assistant, not a marketing suite). It loses on scale (Grammarly's 30M users vs. Språkmotor's SME base), team features (Grammarly's workflow collaboration, tone-library management, brand voice templates are enterprise-grade), and integrations (Grammarly's Word/Docs/Slack/Outlook embedding is seamless; Språkmotor is standalone). For Swedish SMEs and individual writers wanting EU-hosted grammar assistance, Språkmotor competes. For cross-border teams, marketing campaigns, or Fortune 500 compliance, DeepL Write or Grammarly are stronger. For pure writing craft, ProWritingAid is deeper.
