Upload a manuscript or pick from Slima
3 min read
AI Beta Readers doesn't require your draft to live in Slima. Two paths in:

Pick from existing Slima books
Easiest. On the Beta Readers home list:
- All your "active" + "archived" books
- Click → next step (pick service)
- Slima reads the book directly; no re-upload needed
Upload an external manuscript
Got a draft elsewhere? Drop it in:
Supported formats
| Format | Handling |
|---|---|
| Word (.docx) | Heading 1 splits chapters |
| Markdown (.md) | One file = one chapter |
| Scrivener (.zip) | Binder structure preserved |
| Plain text (.txt) | No chapter split, single file |
Upload limit: 20 MB per file and 300K words per upload.
After upload
- Slima parses chapter structure + word count
- Preview: "N chapters, N,NNN words"
- Pick which chapters to include in the report (e.g. only the first 3)
Not turned into a Slima book
Uploaded manuscripts don't auto-become Slima books — they're scoped to this run. If you want to write in Slima too, use the Import existing manuscript path separately.
What gets read
| Source | Default scope |
|---|---|
| Slima book | Files tagged "Manuscript" (notes excluded) |
| Uploaded manuscript | All chapters (you can deselect) |
