TextCortex

TextCortex is an AI-powered productivity and enterprise AI platform designed to help individuals and organizations use artificial intelligence across writing, research, knowledge management, data analysis, workflow automation, and everyday business tasks. The platform has evolved from an AI writing assistant into a broader enterprise AI infrastructure product centered on AI agents, company knowledge, connected applications, and access to multiple large language models from different providers. TextCortex currently describes its platform as a way to organize, deploy, and govern AI agents across an organization.

TextCortex was founded in 2021 in Berlin, Germany. The company initially focused heavily on AI-assisted writing and natural-language generation, providing tools that could help users rewrite, summarize, expand, translate, and generate text directly inside the applications where they worked. TextCortex later expanded into knowledge management, AI agents, automation, integrations, and enterprise AI deployment.

One of the platform’s major capabilities is its AI writing assistance. TextCortex can help users create and improve different types of text, including emails, articles, marketing copy, summaries, rewrites, and other professional communications. Its browser extension places AI assistance directly into many websites and applications, reducing the need to switch between a separate chatbot and the application where the user is actually working. TextCortex currently says its browser experience works across 30,000+ platforms and websites.

TextCortex has expanded significantly into AI agents. Users can create custom agents designed for specific tasks, and the platform provides a visual agent builder intended to let organizations configure agents without writing code. Agents can be connected to company data and external tools so they can retrieve information and, where supported, take actions rather than simply return a generated answer.

The platform’s Knowledge Bases are designed to give AI agents access to an organization’s own information. Users can connect documents, company files, internal resources, and supported applications so that agents can retrieve relevant information when answering questions or completing tasks. TextCortex’s documentation describes knowledge bases being used for areas such as sales and customer success, HR, legal and compliance, product and engineering, and marketing and content.

Knowledge management is particularly important to TextCortex’s current positioning. Rather than relying only on general-purpose language models, the platform can search connected organizational data and generate responses grounded in that information. TextCortex describes this as combining knowledge search with AI so employees can find information, summarize documents, and generate insights from company knowledge.

TextCortex also provides Deep Research and web-search capabilities. These tools allow users and agents to gather information from internal knowledge and the internet, making the platform useful for research, analysis, reporting, and decision support. Its current pricing page lists knowledge search, deep research, and data-analysis functionality among features available across its plans.

Another major capability is data analysis. Users can upload spreadsheets and reports and ask TextCortex to analyze, summarize, or transform the information. The platform is designed to combine data analysis with its knowledge and agent functionality so users can work with both structured and unstructured information in the same environment.

TextCortex has also developed workflow automation tools. Its current platform includes visual workflow automation and scheduled automations that allow AI agents to run recurring tasks without requiring the user to be present. The company says automations can be scheduled daily, weekly, or monthly, with results delivered through notifications or email.

The platform follows a model-agnostic approach. Rather than tying users to a single AI provider, TextCortex provides access to multiple models, including models from OpenAI, Anthropic, Google, Mistral, and other providers. Recent platform updates have added newer models such as GPT-5.5 Pro, Claude models, Gemini models, and DeepSeek models. This allows organizations to select models according to capability, cost, or specific task requirements.

TextCortex also emphasizes data privacy and enterprise security. The company states that customer data is not used to train or fine-tune models, and it hosts its services on GDPR-compliant infrastructure in the European Union. Enterprise features include SSO, SCIM, SAML, centralized billing, dedicated deployment, and priority support. The platform also states that it is SOC 2 and ISO 27001 certified.

Integrations are a major component of the platform. TextCortex provides direct integrations with applications such as Google Drive, Google Docs, Microsoft OneDrive, Microsoft Outlook, Microsoft Teams, SharePoint, Dropbox, Notion, Slack, Salesforce, HubSpot, Zendesk, Freshdesk, Jira, Klaviyo, Apollo, and other services. It also supports Zapier and Make, allowing organizations to extend TextCortex into thousands of additional applications.

Its integration system is increasingly built around connectors and agent skills. Connectors provide agents with access to data and applications, while skills determine what an agent does with that access. For example, TextCortex describes workflows where an agent can retrieve information from a CRM, use a knowledge base to understand the context, and then perform an action in another application.

TextCortex’s Browser Extension remains an important part of the product. It enables users to access AI assistance within websites and applications, making it useful for writing, summarization, research, translation, and general productivity work. TextCortex also provides desktop and mobile experiences in addition to its browser-based tools.

The platform also includes a Text Generation API, allowing developers to generate an API key from their account and integrate TextCortex’s generation capabilities into software and workflows. More recent API updates added chat-response formats and streaming responses, expanding its usefulness for application developers and custom AI implementations.

TextCortex is multilingual and currently states that it supports more than 25 languages. Its official FAQ specifically names English, Dutch, German, Ukrainian, Romanian, Spanish, Portuguese, French, and Italian, while its earlier localization work introduced an interface available in more than 25 languages.

The platform is aimed at a broad range of professional teams. Current TextCortex material discusses use cases involving marketing, sales, customer support, HR, legal and compliance, product and engineering, finance, research, knowledge management, and employee productivity. This reflects the platform’s transition from a writing assistant into a more general enterprise AI system.

TextCortex reports 2.4 million users worldwide and publishes enterprise case-study metrics around productivity, AI adoption, and time savings. These are company-reported figures rather than independently audited product-performance results, so they are best treated as vendor claims.

The platform is particularly strong for organizations that want to combine AI writing, company knowledge, multiple AI models, agentic workflows, and existing business applications in one environment. It is less focused on simple consumer-only AI writing than the earlier generation of TextCortex products. For businesses with complex knowledge and workflow requirements, its enterprise functionality is a major advantage, while smaller users may find some of the advanced capabilities unnecessary.

Review

TextCortex has evolved considerably and is now more compelling as an enterprise AI platform than as a simple AI writing assistant. Its combination of AI agents, knowledge bases, research, multiple AI models, integrations, workflow automation, and data analysis makes it suitable for organizations that want AI to operate across existing business systems.

Third-party feedback is generally positive. G2 currently lists TextCortex at 4.7/5 based on 872 reviews. Recent reviewers have praised the platform for flexibility, AI model selection, writing assistance, knowledge-base functionality, and customizable agents. Some users have also reported issues with limited creations or consumption-based usage, particularly when using the platform heavily.

Trustpilot currently gives TextCortex a 3.5/5 TrustScore from 364 reviews, showing a more mixed picture. Some recent negative reviews focus on billing and subscription experiences, while positive reviews highlight multilingual writing support and the browser extension. Because reviews on different platforms can vary substantially, the product’s G2 score and Trustpilot score should be considered together rather than relying on either one alone.

One of TextCortex’s biggest advantages is its model flexibility. Users are not limited to a single AI provider, and organizations can connect their own data to agents and knowledge bases. This can make TextCortex more useful than a standalone chatbot for companies that need AI to work with internal documents, workflows, and business applications.

The main drawbacks are complexity and pricing structure. TextCortex now offers a large collection of enterprise functions, connectors, models, agents, and usage mechanisms, which can be more than a casual user needs. Premium AI usage also draws from a compute budget, and additional usage can incur extra charges. This makes understanding actual usage costs important for organizations with heavy AI workloads.

TextCortex is a strong choice for businesses seeking AI agents, knowledge management, research, workflow automation, writing assistance, and multi-model AI access in one platform. Its current enterprise capabilities distinguish it from traditional AI writing tools, although smaller users may find simpler alternatives easier to adopt.
