How FileMind compares
Zotero and Mendeley are reference managers: they organize what you import into them. FileMind works on the folder of PDFs you already have, and hands the result to your reference manager. Here is where each one fits.
| Capability | FileMind $39 one-time | Zotero Free | Mendeley Free | Manual Free |
|---|---|---|---|---|
| Works on the PDFs you already have, without importing | Point it at any folder | Import into a Zotero library first | Import into a Mendeley library first | Yes |
| Metadata extraction | DOI/arXiv lookup, then layout parsing; evidence and confidence score on every field | Retrieves metadata for imported PDFs | Extracted on import | Copy-paste from the publisher |
| File renaming | Batch proposals in confidence tiers; you approve before anything changes | Renames attachments from item metadata | File Organizer renames on import | One file at a time |
| Undo a whole rename batch | Journaled, one-click rollback | No | No | No |
| Search inside the papers | Keyword + meaning-based hybrid, reranked | Full-text keyword search | Full-text keyword search | Ctrl+F in the file explorer |
| Ask questions, answered from your papers with citations | Yes, page-level citations enforced | Not built in (third-party plugins exist) | No | No |
| Scanned PDFs made searchable | Bundled OCR, runs locally | Not built in | Not built in | No |
| Where your files live | In your own folders, renamed in place | Zotero storage, or linked files | Mendeley library | Your own folders |
| Privacy | Everything local; no account; cloud AI optional | Local; cloud sync optional | Account and cloud sync required | Local |
| Price | $39 one-time | Free (open source); paid storage tiers | Free; paid storage tiers | Free |

FileMind + Zotero: better together
Zotero is a very good reference manager, and it can rename the PDFs you import from
their metadata. What it cannot do is start from a Downloads folder with 600 unnamed
papers in it. FileMind does that part: it scans the folder as it is, looks up each
paper's DOI or arXiv record, shows you the evidence for every proposed
Author_Year_Title.pdf
name, renames what you approve, and indexes everything for semantic search and cited Q&A.
When the folder is clean, FileMind pushes papers to Zotero directly, or exports BibTeX, RIS and CSV. Use FileMind for the backlog and for discovery; keep Zotero for citations in your writing.
Why not just rename files manually?
The math: 1,000 papers × 2 minutes each = 33 hours of copy-pasting metadata. That's before accounting for the papers where the title isn't on the cover page, the ones with identical author/year combinations, or the scanned PDFs with no extractable text at all.
FileMind does the same work in minutes, and shows you the exact reasons behind every proposed name. You review and approve; it does the mechanical work, and any batch can be rolled back.
Why not Mendeley?
Mendeley Reference Manager needs an Elsevier account and syncs your library to Elsevier's servers. It organizes what you import into it, on its terms, and if you leave, the organized library is in a format you don't control.
FileMind renames your files in place. Your PDFs stay exactly where they are, in your filesystem, named as readable strings, backed up with whatever tool you already use. The entire FileMind database is a single SQLite file you can inspect, copy, or delete at any time. No account, no cloud required, no vendor lock-in.
