Library
Upload once, reuse anytime — Library is where the documents you want your Twin to pull from live.
Introduction
Library is your Twin's persistent file repository. Anything you upload here stays available as reusable context — you can attach files to a future chat with one click instead of re-uploading every time.
This is the place for any file you want your Twin to draw on — reference documents, sample work, communication-style guides, email templates, whatever you'd otherwise re-attach to chats over and over.
What Shows Up in Library
Library is the surface for files you've manually added to your Twin. That includes:
- Files you upload directly using the Upload button on the Library page.
- Files you attach in a chat. Once uploaded, these are stored as Library files and appear in the list.
Library does not automatically pull in content from connected Data Sources, meeting transcripts, email attachments, or files your Twin generates in chats.
Library vs. Data Sources
Both surfaces give your Twin knowledge to draw from. The difference is how content gets in.
| Library | Data Sources | |
|---|---|---|
| What it's for | Files you manually upload as persistent, reusable reference material | Content from connected systems that syncs continuously |
| How content gets in | You upload it | An admin connects the source; content syncs automatically |
| Who controls it | You | Your admin |
| Best for | A deck, RFP, or style reference you want to chat with repeatedly — a file that isn't in (or shouldn't be synced from) a connected system | Day-to-day work artifacts in tools like Confluence, Box, GitHub, SharePoint |
What You Can Upload
Library accepts the common file formats your Twin's extraction pipeline can process:
.pdf · .docx · .doc · .pptx · .xlsx · .csv · .txt · .md · .html · .json · .png · .jpg · .jpeg
Limits: Up to 10 files per upload, with a combined size up to 200MB per upload request.
After upload, your file is processed and indexed — typically within a minute or two. Once it's ready, your Twin can ground answers in it.
Uploading Files
- Click Library in the left navigation.
- Click Upload in the top-right corner.
- Select one or more files from your computer (up to 10, up to 200MB total).
- Wait for processing to complete. The file appears in the list with its name, sharing state, and date added.
Chatting With a Library File
The fastest way to use Library is to select files and start a chat with them pre-loaded as context.
- On the Library page, select one or more files using the checkboxes on the left of each row. The header updates to show
X files selected. - Click Chat in the bulk-action toolbar that appears.
- You're taken to a new chat with the selected files attached as removable context chips in the message bar. Remove any you don't want before sending.
- Ask your question. The Twin grounds its answer in the attached files.
You don't always need to start from Library. Once a file is uploaded, your Twin will surface it as context in any chat where it's relevant. Selecting files from Library is the fastest way to scope a chat to a specific set of documents.
Sharing Files
Every file in Library has a sharing state, shown in the Sharing column. The lock icon means the file is private. Click the icon on any row to change who can access it.
Sharing levels
| Level | Who can access |
|---|---|
| Restricted | Only your Twin can use the file. People with persona access to your Twin cannot see it. |
| Only me (default) | You, and anyone with full persona access to your Twin. |
| Specific people | You explicitly invite teammates by name or email. |
| Anyone at [your org] | Everyone in your organization can access the file. |
How sharing interacts with personas
The default — Only me — extends access to anyone you've given full persona access to your Twin. So if a colleague has full persona access, they can ground their queries on your Library files unless you've set the file to Restricted.
Deleting Files
Library files stay until you delete them — there is no automatic expiry. Once removed, the file is no longer accessible to you or anyone it was shared with, and your Twin no longer grounds answers in it.
What To Put in Library
Library is for reference content your Twin can pull from on demand. A few common examples:
Sales and customer-facing reference material
- A gold-standard RFP response you want future drafts to mirror.
- A pricing sheet, product one-pager, or competitor positioning doc you reach for in customer chats.
Personal style and voice
- A communication style guide with examples of how you write emails, Slack messages, and internal updates.
- Your go-to email templates — initial outreach, follow-up, decline, escalation.
- Sample work in your own voice — your best status reports, customer responses, or exec summaries — that your Twin can use as reference when drafting on your behalf.
Project context that doesn't live in a connected system
- A vendor-sent PDF you want to chat with repeatedly without re-uploading.
- A locally-iterating deck that isn't in Drive or SharePoint yet.
- An exported CSV you want to ask analytical questions against.
What NOT to put in Library
- Content already in a connected Data Source — let Data Sources sync it instead of duplicating.
- One-off files for a single question — drag them into the chat and move on. They'll appear in Library anyway, and you can delete them later if you don't want them lingering.
Frequently Asked Questions
Library is for files you manually upload and want as persistent Twin context. Data Sources are connected systems (Confluence, Box, GitHub, SharePoint, and so on) that sync content automatically. Both end up as queryable knowledge for your Twin — the difference is how content gets in, and whether you or an admin is in control.
Typically a minute or two. Larger files or bulk uploads of 10 files at once can take longer. You'll see the file appear in the list once processing starts; it's ready to chat with once indexing is complete.
Yes. Files stay in Library until you remove them — there's no auto-expiry. Deleting a file removes it from your Twin's knowledge and revokes access for anyone you'd shared it with.
By default, Only me — meaning you, plus anyone you've granted full persona access to your Twin. You can tighten that to Restricted (your Twin only), or open it up to Specific people or Anyone at [your org] from the sharing modal.
Yes. Open the sharing modal on the file and choose Anyone at [your org]. Everyone in your organization will be able to use the file as context with their Twin.
Not by default — Library is your personal file repository. Individual files can be made org-accessible by sharing them with Anyone at [your org].
Library supports .pdf, .docx, .doc, .pptx, .xlsx, .csv, .txt, .md, .html, .json, .png, .jpg, and .jpeg. You can upload up to 10 files at once, with a combined size of up to 200MB per upload request.
Yes. In-chat uploads are stored as Library files and appear in your Library list, so you can reuse them later without re-uploading.
No. Library is for files you manually upload. Twin-generated artifacts and meeting transcripts are stored separately.
