    Create a shareable Word Aligner diagram that shows which words match across two or more stacked lines of text (a translation and its source, an interlinear gloss, IPA, etc.). Returns a URL that opens the interactive diagram, plus a preview image. Use this when the user wants to translate a phrase and show word correspondences, align a translation with its source (including RTL scripts like Hebrew or Arabic, or vertically written ones like Japanese and Mongolian), or build a Leipzig-style interlinear gloss. Word indices are 0-based token positions. Tokenize each line the same way the tool does before assigning indices: - Whitespace always splits ("I have been going" -> I[0] have[1] been[2] going[3]). - The characters in settings.tokenSplitChars (default ".-|") also split and are then removed from the rendered text, so "go.PST.IPFV" becomes three tokens (go, PST, IPFV) and the dots disappear. For Leipzig glosses set tokenSplitChars to "-|" to keep the dots. - Punctuation stays attached by default ("Hello, world!" -> Hello,[0] world![1]). - In RTL lines, word 0 is the logically first word (rightmost on screen); index in reading order. - Japanese and Chinese are written without spaces and nothing is segmented for you: put spaces where the alignment units should be. For a vertically written script set settings.axis to "columns". Every line then becomes a vertical column and the connectors run sideways. Set orientation per line: "vertical" stacks the characters (Japanese, Chinese), "sideways" rotates the line a quarter turn (traditional Mongolian, and Latin runs inside vertical text), "upright" leaves a translation as horizontal word boxes. The first line is the leftmost column, so for Japanese and Chinese, whose columns read right to left, list the translation first and the script second. Each alignment is [lineA, wordA, lineB, wordB]; the two lines must be neighbours in the stack (|lineA - lineB| = 1), which means one above the other in rows and side by side in columns. To express many-to-one, list each target word as its own tuple. Tokens that share a connection group get the same color automatically.

Aligner — word-by-word translation visualizer

aligner.tinygods.dev

Word Aligner is a free web tool that shows which word matches which across stacked lines of text. Type or paste a sentence and its translation, click a word and then its match on the line above or below, and curved connectors draw the alignment between them. Add extra rows for glosses or IPA, then export the diagram or share it with a link.

No accounts, no machine translation — you stay in control of every link. Great for lessons, social posts, grammar notes, and conlang documentation.

What it's for

  • Language learners — see exactly why a translation says what it does: which source word became which target word, what gets dropped, and where word order changes.
  • Teachers — build handouts, slides, and flashcards; export a clean PNG or SVG and drop it into a lesson without retyping anything.
  • Linguists — produce Leipzig-style interlinear glosses with morpheme alignment, case/agreement tags, and free translations.
  • Conlangers — show how a constructed language maps onto English, with custom script fonts, gloss rows, and IPA.

What it does

  • Multi-line alignment — stack as many rows as you need (source, translation, gloss, IPA); links connect vertically adjacent lines.
  • Manual word linking — click a word, then its match; supports one-to-many and many-to-one links and freely crossing connectors for reordered translations.
  • Interlinear glosses & IPA — add annotation tiers above or below any line.
  • Right-to-left scripts — Hebrew, Arabic, and mixed LTR/RTL layouts.
  • Vertical writing systems — stand the whole diagram up as columns for Japanese tategaki, Chinese, or traditional Mongolian; characters stack or the line rotates, chosen per line, so a horizontal translation stays readable beside it.
  • Tokenization control — choose how text splits into word boxes (split characters, a join marker for fixed expressions, optional punctuation handling).
  • Per-line typography — font, size, spacing, and direction per line; custom and Google Fonts.
  • Exports — PNG, SVG, PDF, and a self-contained HTML file; exports match the preview, including custom-font shaping.
  • Shareable URLs — the whole alignment (text, links, and visual settings) is encoded in a ?data= link.

Examples

Browse ready-made examples — bilingual pairs, Turkish interlinear with IPA, RTL scripts, vertical Japanese and traditional Mongolian, Tagalog compounds, Japanese–Chinese–English word order, and more interlinear glosses — at aligner.tinygods.dev/examples. Open any one in the editor to adapt it.

How it works

Edit your lines in the line editor, then link words in the preview.

Tune colors, tokenization, and fonts in settings, then export or share.

Word alignment vs. interlinear vs. parallel text

  • Interlinear translation places a gloss directly under each source word — compact, but it hides reordering. Aligner keeps both sentences on their own line and draws connectors, so reorderings, splits, and merges stay obvious.
  • Parallel text is side-by-side bilingual reading for long-form study. Aligner focuses on one sentence pair at a time with explicit connectors showing which tokens correspond.

API

Word Aligner has a free HTTP API for generating alignment links programmatically.
