# ThinkEx

> A workspace for source-heavy study, research, and creation.

ThinkEx is a workspace for source-heavy work. Keep PDFs, documents, images, folders, and AI chat in the same place, then choose exactly what the AI should use.

## When a Chat Thread Is Not Enough

ThinkEx is not a file dump behind a chat box. The sources stay visible and usable while you work:

* Open PDFs, documents, images, and folders in a workspace.
* Arrange sources side by side while you read, compare, or write.
* Ask AI about the exact items or selected passages you choose.
* Share workspaces with other members when the work is collaborative.

## How It Is Different

| 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 |

## Built On Cloudflare

It uses Durable Objects for workspace, document, AI, sandbox, and conversion coordination; D1 for relational app data; R2 for workspace file storage; Workflows for extraction; Containers for code execution and file conversion; Workers AI, Browser Rendering, and Email for product features.
