Zentor AI assistant is a cross-tool productivity workspace that connects to the apps people already use to handle recurring knowledge work. It is designed for solo founders, freelancers, students, creators, marketers, sales teams, managers, recruiters, consultants, and developers who want an AI assistant that can act inside their tools rather than only provide chat responses. Zentor connects with Notion, Airtable, Slack, Discord, Gmail, Google Drive, Google Calendar, Google Tasks, and Outlook. Users can summarize sales activity, check inventory and supplier lead times, draft invoice follow-ups, create tailored resumes and cover letters, update application trackers, schedule reminders, search content libraries, prepare responses, and produce ready-to-use documents, images, and presentations. Its persistent workspace memory stores preferred formats, tone, and repeat workflows, while integrations support AI automation across email, documents, spreadsheets, messaging, research, scheduling, and content operations. Zentor reduces manual coordination by completing work in the systems where it belongs, instead of making users copy answers between separate AI chats and business apps. Its memory can be exported or deleted and is designed to remain portable across AI models, providing a practical alternative to isolated assistants and fixed-rule automation tools. Zentor is available as a paid web workspace with a monthly subscription and usage credits.
