How docrew delivers
Your files stay on your device
Passports, contracts, medical records -- docrew processes them locally via sandboxed Python. Only extracted text reaches the AI model. ChatGPT requires uploading files to OpenAI's servers.
Real parallel agents
Run two or three agents simultaneously in split panes and watch them all work at once. ChatGPT's Codex runs background tasks in a list -- you don't see the live work.
Select-to-context editing
Agent writes a document, you see it inline, select a paragraph, type 'rephrase this' and see the result instantly. No file downloading, no switching apps.
Mobile-to-desktop delegation
Send a task from your phone while commuting. Your desktop agent processes local files and sends back the result. ChatGPT mobile has no connection to your desktop files.
Where ChatGPT chats well
- Massive brand recognition and the largest user base of any AI assistant.
- GPT Store with thousands of community plugins for specialized tasks.
- Built-in web browsing capabilities.
