Claim this listingFindThatSoftware verdictEditorial ruling
Shortlist it if you regularly assemble long PDFs with repeated cross references, such as legal briefs, tender bundles, compliance reports or manuals, and you are tired of adding go-to-page links one by one in Acrobat. The free tier is a real trial: run your own document through the scan and the CSV match report before paying anything, and only buy Pro if the matches look right.
Read the full verdict
Check that your PDFs have selectable text and are not signed or encrypted, because scanned bundles need OCR elsewhere first and signed files are rejected. The trade-off against Acrobat Pro or a full PDF editor is narrow scope for a one-time price with local processing; if you already pay for a PDF editor and only link a few references a month, you probably do not need this. The product went live on the Chrome Web Store in late October 2026 with one user and no ratings, so treat it as an early release from a months-old company.

In short
Kastovia PDF Reference Linker is listed under E-signature & Documents, reviewed for Indian buyers. All-in it runs about ₹4,570 one-time for a GST-registered business (€49 one-time sticker plus about 3.5% card forex). FindThatSoftware rates it best for lawyers, paralegals and compliance teams building PDF bundles with many repeated exhibit or annexure references; a poor fit for scanned or image-only PDFs, or signed, encrypted and XFA files, which the vendor says are unsupported.

More
The vendor lists the price in euros with tax included. The Dodo Payments checkout opened from India offered to pay in rupees at a converted price, still labelled tax included, with 18 percent GST shown inside the total, so the rupee amount moves with the exchange rate. The vendor offers a full refund on request within 14 days of purchase, which deactivates paid export.
Indicative, not a bill. The exchange rate is a single mid-market reference, not a live feed, and GST-registered businesses may reclaim input credit. Confirm current pricing on the vendor site.

What is Kastovia PDF Reference Linker?
PDF Reference Linker is a Chrome extension from Kastovia Holdings LLC, a small software and automation company registered in Tbilisi, Georgia in June 2026. You map each reference label (such as Exhibit A or Section 4) to a destination page once, by hand, from the PDF's own bookmarks or from a CSV with label and target page columns, and the extension finds every exact whole-word match in the selectable text. You review each source and destination, deselect false positives, download a CSV match report, and with Pro export a separate copy of the PDF with internal click links; the original file is never overwritten. The vendor says all reading, matching and export run inside the extension, and only the license check and checkout touch the internet. Version 1 handles one unsigned, unencrypted PDF at a time up to 50 MiB and 500 pages, 500 labels and 10,000 matches, and it has no OCR, no fuzzy matching and no matching of labels that wrap across lines.
What you gain, and what you give up.
The case for
- Free tier covers the full scan, match review and CSV report, so you can test on a real document before paying
- The vendor says PDFs, filenames and mappings never leave the device; only license checks go online
- One-time Pro price with no subscription and no license expiry for version 1, usable on three browser installs
The catch
- Very new: version 1.0.0 was updated on the Chrome Web Store on 26 October 2026 with one user and no ratings, from a company registered in June 2026
- Exact whole-word matching on a single line only, with no OCR, so wrapped labels and scanned pages are missed
- Every paid export needs an online license check, so linked export does not work offline
- Priced in euros by a Georgian company; the checkout served to an Indian buyer added GST, but there is no statement about issuing GST invoices with a buyer GSTIN
Best for
- Lawyers, paralegals and compliance teams building PDF bundles with many repeated exhibit or annexure references
- Technical writers and consultants who produce long reports or manuals with appendix cross references
- Buyers who want document text kept on their own machine rather than uploaded to a web PDF service
Who should avoid it
- Scanned or image-only PDFs, or signed, encrypted and XFA files, which the vendor says are unsupported
- Teams that need a general PDF editor for forms, signing, OCR or external web links
- Anyone who does not use Chrome on a desktop

Kastovia PDF Reference Linker questions
Does Kastovia PDF Reference Linker give a GST invoice in India?
- Whether Kastovia PDF Reference Linker issues an India GST invoice is not verified yet. Foreign-billed tools usually don't, in which case a registered business reclaims GST via reverse charge; confirm the vendor's billing before you buy.
Is Kastovia PDF Reference Linker good for Indian small businesses?
- It suits lawyers, paralegals and compliance teams building PDF bundles with many repeated exhibit or annexure references. It bills in a foreign currency, so expect the card forex markup on every charge. It is not the right pick for scanned or image-only PDFs, or signed, encrypted and XFA files, which the vendor says are unsupported.
Does Kastovia PDF Reference Linker have a free plan?
- Kastovia PDF Reference Linker lists a free plan, but check the official pricing page for current usage limits before choosing it.
