Already have your terms in a spreadsheet? Upload or paste a CSV of term, definition pairs and Brainfy builds an instant deck — with automatic delimiter detection — then study it with spaced repetition.
If your study material already lives in Excel, Google Sheets, or a plain CSV, there is no reason to retype it. Brainfy reads a two-column term/definition layout and turns each row into a card — and it auto-detects whether your file is comma, tab, or semicolon separated.
From Excel or Google Sheets, save or download a CSV with term in the first column and definition in the second.
Drop the file into a deck or paste the text — Brainfy auto-detects the delimiter, so commas, tabs, and semicolons all just work.
Your rows become a deck for spaced repetition plus Learn, Test, and Match — and you can export back to CSV anytime.
Two columns: term in the first, definition in the second — one card per row. A header row is fine. Comma, tab, or semicolon separators are auto-detected.
Yes — paste the text directly into a deck and Brainfy detects the delimiter. CSV, TSV, Anki text, and Quizlet exports all work.
Export your sheet as a CSV (or copy the cells) and import that. Brainfy reads the CSV/TSV, not the native .xlsx file.
Yes — every deck exports to CSV, which re-imports into a spreadsheet, Anki, or Quizlet. No lock-in.
Yes — free during beta, no ads, no signup needed to try.
