What is TextCortex?

TextCortex is an enterprise AI platform that combines writing assistance, knowledge management, and custom AI agents into a single infrastructure for organizations. Originally launched as an AI writing tool, it has evolved to serve over 2.4 million users worldwide, with a particular focus on mid-market and enterprise teams that need secure, context-aware AI embedded into their existing workflows. The platform runs via a browser extension compatible with 30,000+ applications, a web interface, a desktop app for Mac, and an API and is accessible without switching tools. Headquartered in Berlin, Germany, it is EU-hosted, GDPR-compliant, SOC 2 certified, and ISO 27001 certified, which sets it apart for organizations with strict data sovereignty requirements.

Key Features

  • AI Text Generation: Creates sentences, paragraphs, and longer content from prompts or sample text, covering emails, blog posts, marketing copy, and more.
  • Paraphrasing and Rewriting: Rephrases content while preserving the original meaning, with multiple output options and the ability to rewrite articles up to 2,000 words on the Unlimited plan.
  • AI Text Summarization: Condenses long documents into brief summaries, useful for research, reports, and internal knowledge sharing.
  • Multi-language Support: Generates and localizes native content in over 25 languages, going beyond translation to support global content workflows.
  • Company Knowledge Search: Connects to internal sources such as SharePoint, Google Drive, wikis, and CRM systems so AI agents can answer questions with citations drawn from company data.
  • Interactive AI Agents (ZenoChat): A no-code builder lets teams create custom agents trained on company knowledge, using multiple LLMs including GPT, Claude, Gemini, and Mistral, with no vendor lock-in.
  • AI Workflow Automation: Automates recurring tasks like market research, email outreach, and report creation through integrations with Zapier, Make, and Pipedream.
  • Grammar and Tone Check: Detects spelling and sentence errors, evaluates emotional tone, and checks for plagiarism to support writing quality at scale.

Use Cases

  • Students: Use the paraphrasing and rewriting tools to rephrase notes and improve academic papers, resulting in better writing quality and originality without producing fully AI-generated work.
  • Content creators and marketers: Generate ideas, produce draft copy for blogs and social media, and maintain consistent brand tone, reducing the time spent overcoming writer's block.
  • Enterprise and global teams: Upload up to 100GB of company documents, PDFs, and drive data to build internal knowledge bases, then use AI agents to handle customer support queries, internal search, or data analysis tasks.
  • Professionals using daily apps: Enhance emails, documents, and support tickets directly inside Gmail, Outlook, Freshdesk, Google Docs, and Zendesk through the browser extension, without leaving the tools they already use.
