AI Tools

AI Summarize

Summarize a PDF of any length. Long documents are handled with map-reduce — each chunk is summarized, then combined — so the input size is effectively unbounded.

PRO / ENTERPRISE only 100 credits / callSynchronous

Overview

Upload a PDF; the summary comes back inline in the response (no download URL). Billed a flat 100 credits per call, whatever the document length.

POSThttps://api.bytefuse.in/api/v1/ai/summarize

Paid plans only

The AI tools require a PRO or ENTERPRISE plan. Anonymous calls return 401; an authenticated free-tier account returns 403. This gate runs before any credits are touched.
