Upload a manuscript or pick from Slima
Last updated May 14, 2026 · 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 / .markdown) | One file = one chapter |
| Plain text (.txt) | No chapter split, single file |
| PDF (.pdf) | Text extracted from the file |
| EPUB (.epub) | Text extracted from the file |
Uploads have a size and word limit (subject to change) — if you exceed it, you'll be told at upload time.
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)
Upload creates a new book
When you upload a manuscript, Slima creates a new Slima book and saves the content into it (synced to your account). The reading report runs against that new book.
So if you want to keep writing in Slima afterward, just open that book — no need to import again. (If you're separately bringing an older draft into Slima, you can also use the Import existing manuscript flow.)
