Ever uploaded a document to ChatGPT and then spent 10 minutes trying to find it again three days later?
OpenAI quietly introduced a Library feature back in March 2026 ... and it's now available to all users, including free accounts. It solves one of the most annoying things about ChatGPT.
Here's how it works.
Every file you upload to ChatGPT ... PDFs, Word documents, spreadsheets, presentations, images ... gets saved automatically to your Library. Same goes for any files ChatGPT creates for you, including generated images.
The useful bit is you can pull any saved file back into a new chat. Just use the attachment menu and choose "Add from library." No more scrolling through months of old conversations.
A few things worth knowing:
- Your chats are NOT stored in Library ... it's purely for files
- Memories are separate too ... Library doesn't touch those
- Project files live in their own space inside Projects
- Deleting a chat doesn't delete the files you uploaded ... they stay in Library until you remove them
Storage depends on your plan. Free gets 500MB. Plus and Business get 20GB. Pro gets 100GB.
My honest take?
It sounds small but it changes how you work. If you're regularly uploading client templates, engagement letters, or reference documents ... you only need to upload them once. Then reuse them across any conversation.
Having said that, I prefer to keep important files that I want to be referenced often as 'project files'. And I find myself now working mainly inside Codex (ChatGPT) and Cowork.
Have you spotted the Library in your ChatGPT yet? Are you using it? ๐
