Tatoeba Sentence Corpus Scraper

Tatoeba Sentence Corpus Scraper

Scrape Tatoeba sentence pairs by language, search term, or tag, up to a million per run. Every sentence comes with its translation, language codes, and tag metadata. No API key or login. Export to CSV, JSON, Excel, or XML.

Tatoeba's official API needs registration and rate-limits you. This reads the public sentence corpus directly, filtered by source language, target language, search term, or tag, and returns each match in one fixed schema.

Who uses it	What they scrape Tatoeba for
Language learners	Find example sentences for a word or phrase in their target language

What it does

This Actor collects Tatoeba sentences and their translations by language pair, search query, or tag, and returns each one as a flat row.

• 🔍 Search term: filter sentences by a word or phrase, like 'hello'.
• 🌐 Language pair: choose source and target languages from 50+ options.
• 🏷️ Tag filter: narrow to proverbs, idioms, greetings, and more.
• 📊 Flat output: each sentence and its translation in one row, ready for analysis.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

Configure the run

Drive the Actor from a search term, source language, target language, and tags, alone or together, and filters run as each sentence is read so only matches reach your dataset. The Input tab lists every parameter.

A first run with the defaults:

{
  "maxItems": 10,
  "query": "hello",
  "fromLanguage": "eng"
}

A larger pull:

{
  "maxItems": 200,
  "query": "hello",
  "fromLanguage": "eng"
}

Then prompt it in plain language to run the scraper and read back the results.

Troubleshooting

Why am I getting no results?

Your filters may be too restrictive. Try removing the tag or search term, or choose a more common language pair. Also check that the query is spelled correctly.

The run is taking too long.

Lower maxItems or narrow your filters. Scraping a million sentences with many translations can take time.

Some sentences are missing translations.

Not every sentence has a translation in your target language. Leave toLanguage empty to see all available translations, or choose a more common language.

I get an error about language codes.

Use the dropdowns to select languages; they provide valid ISO 639-3 codes. If you type a code manually, ensure it is in the list.

FAQ

Question	Answer
Do I need a Tatoeba API key?	No. This Actor reads the public Tatoeba website directly, so no registration or key is required.
How many sentences can I scrape in one run?	You can set maxItems up to 1,000,000. The run stops when it reaches that number or no more matches exist.
Can I filter by both language and search term?	Yes. Set fromLanguage, toLanguage, and query together to get only sentences in that pair containing that term.
What are tags?	Tags are labels like 'proverb', 'idiom', or 'greeting' that Tatoeba users assign to sentences. Use the tags input to filter by them.
What languages are supported?	The fromLanguage and toLanguage dropdowns list 50+ languages, including English, Spanish, Chinese, Japanese, and Esperanto.
Can I get all translations for a sentence?	Yes. Leave toLanguage empty to return every available translation for each source sentence.
What output formats are available?	You can export the dataset as CSV, JSON, Excel, or XML from the Apify platform.
Is the data live?	Yes, each run fetches the current public Tatoeba pages, so you get up-to-date sentences and translations.
Can I schedule regular scrapes?	Yes, use Apify's scheduler to run this Actor daily, weekly, or on any cron schedule.
What if I get no results?	Check your filters. A very specific query or rare tag may return nothing. Try broadening the search term or removing a filter.
