Craftstead

Independent software studio

Small tools.
Thoughtfully made.

Craftstead makes focused software for ordinary, repetitive work. Two products so far: Mass Rename, which renames a folder of files from a spreadsheet, and Eldertongue, an Old English dictionary with the full inflection table on every entry.

One developer Two products Separate sites, separate support

Mass Rename's review screen: six files matched to new names from a CSV, with counts for conflicts, illegal names and unmatched rows.

Products

Two tools, each with one job.

They are separate products with their own sites, pricing and support. This page is the shared front door.

01 — File utility

Mass Rename

Rename hundreds of files from a spreadsheet, without uploading a single one.

Give it a CSV or Excel sheet with the current and new names, add the files or a folder, then check the preview row by row. It builds a renamed ZIP in the browser tab, plus a report of what changed and what did not. There is no backend that receives your files; once the page has loaded it also works offline.

Who it is for Invoice scans, photo deliveries, product shots and any folder whose names arrived in a list rather than in the files.

Inputs
CSV, TSV and XLSX, or paste from Excel and Google Sheets.
Names
Build from several columns; the extension actually on disk always wins.
Folders
Rename inside subfolders without moving files between them.
Checks
Conflicts, illegal names and unmatched rows are listed before anything is written.
Price
Free for 50 files per batch. A $19 one-time licence removes the limit; 30-day refund.

02 — Reference

Eldertongue

An Old English dictionary where every form of a word lives on one page.

Each entry carries senses, IPA, syllables, etymology and, where the source record has one, the complete declension or conjugation table. Every cell links to that form, so a reader can go from cyninges back to the genitive row it came from. Bēowulf is available line by line, with its vocabulary linked.

Who it is for Students checking an inflection, readers working through a text, and anyone tracing an English word back through Old English.

Coverage
14,544 headwords with an entry page, drawn from 68,489 Wiktionary entries indexed.
Forms
Declension and conjugation tables with every cell linked to its own place in the entry.
Lookup
Search by headword, or browse English words whose definitions mention an Old English term.
Reading
The whole of Bēowulf, line by line, with linked vocabulary.

About

A small studio, deliberately.

Craftstead is an independent software studio run by one developer. The name is the shared identity behind the products, not a company with a support department: each product is sold, documented and supported on its own domain.

The work starts from a narrow job — a folder that needs new names, a word that needs its paradigm — and stops when that job is done. No dashboards to maintain, no account to create, no subscription where a one-time tool will do.

The products are built to be understood in a minute and used without a manual. Where a product makes a technical promise, such as keeping files in the browser, that promise is stated and limited on that product's own site — not stretched into a promise about everything here.

Contact

Write to the studio.

Product questions are answered fastest on the product's own support page. For everything else — licensing, a bug that spans both, or something you think should exist — email is best.
