PDFBrains

AI Assist lets you drop PDF files into a chat interface and do muti-step merge, compress, split, organize, OCR and 20+ other tools, in a single click. You can reference attached files in your messages with @mentions, and the AI will propose step‑by‑step operations such as splitting, merging, reordering, or extracting pages for your approval. The AI only sees file names, never the actual content, and any server‑side processing like OCR is performed temporarily; the files are deleted as soon as the task finishes. This design keeps the documents in your browser and avoids permanent storage on the service. No sign‑up is required; you simply attach a PDF and receive answers in seconds. The tool is positioned as a quick way to interact with PDFs without exposing their full content to the AI.
