The workspace built for how you study, research, and create.
ThinkEx is a workspace for source-heavy study and research.
Instead of uploading sources into a chat, you keep the actual materials in view: PDFs, docs, images, folders, and AI chat. Arrange them, pick what the AI should use as context, and keep the work grounded in your actual materials.
- Open PDFs, documents, images, and folders in a workspace.
- Put sources side by side while you read or compare them.
- Ask AI about the specific items you choose.
- Share a workspace with collaborators (fellow humans).
| Compared with | What they are good at | Where ThinkEx differs |
|---|---|---|
| ChatGPT, Claude, Gemini | Fast AI conversations | Chat is part of the workspace, next to sources and docs |
| NotebookLM | Asking questions over uploaded sources | Sources stay open, arrangeable, editable, and shareable |
| Obsidian | Markdown files and local knowledge bases | PDFs, images, docs, AI chat, and sharing are first-class |
| Google Drive, Dropbox | Storing and sharing files | Files become source material with docs and AI beside them |
