API and processing

Semantic Scholar API Key - optional. Adds higher rate limits for citation lookups, search, and PDF discovery. A free key is available from Semantic Scholar.
AI Processing Batch Size - how many items are processed at once (1-50, default 5). Lower values use less memory.
Maximum Token Threshold - maximum tokens per request (1,000-128,000, default 4,000). Higher values allow larger documents but can cost more.
Strip AI Thinking Process - hide the reasoning section from thinking-capable models (on by default).
PDF Fetch Timeout - seconds to search for a PDF before falling back to the browser (10-120, default 30).

CAPTCHA Prompt for PDF Downloads - when Google Scholar shows a CAPTCHA during a PDF fetch, choose Ask each time, Always solve, or Never (skip Scholar).

Database Location - where Sciwand stores its local database and cache. Change Directory lets you move it; you can Move Data or Start Fresh. The app quits after migrating, so restart it manually.
Optimize Databases - reclaims disk space by defragmenting the database files. No data is deleted.

Clear Sciwand Data - permanently delete selected data: reference-manager data (Zotero, Mendeley, EndNote, Bookends), custom columns, items and documents, or vector embeddings. Cleared reference-manager data needs a re-sync. Tick what to remove, then Delete Selected (you must confirm).
Full Reset - delete all cached data and require a full library re-sync. The app restarts afterwards.
