💬 AI chat for productivity
Use the chatbot to draft text, improve writing, translate, brainstorm, summarize long content, explain technical topics, prepare messages, compare ideas and get quick assistance. It can help students, writers, creators, professionals and anyone who wants a flexible AI assistant.
🔐 Privacy and transparency
Your prompts, images, audio and files are processed only when you use the related features. AI requests are routed through secure API services, and the app explains data handling in its Privacy Policy.
