Textrix - Paraphrase, Summarise, and Extract Text from PDFs on iOS

Paraphrase in 30 languages. Summarise long passages. Pull text out of PDFs. All on iPhone.

Rewording a paragraph in another language, summarising a five-page brief into something you can actually skim, pulling the text out of a scanned PDF — three jobs that all live in different apps, all need a laptop, and all take longer than they should.

I built Textrix to do them on the phone in seconds. Paste your text, pick what you want done, tap once. The actual transformations run through DeepSeek so the output is closer to a competent human than a 2018 thesaurus.

Rephrase in 30 Languages

The Rephrase tab takes a passage and rewrites it — same meaning, different words and sentence structure — in any of 30 languages. English, Arabic, Chinese, German, French, Japanese, Italian, Spanish, Portuguese, Ukrainian, Indonesian, Finnish, Polish, Dutch, Swedish, Turkish, Russian, Kazakh, Azerbaijani, Uzbek, Bulgarian, Czech, Danish, Korean, Estonian, Greek, Hungarian, Latvian, Lithuanian, and Romanian.

The language list runs along the bottom. Pick one, paste your text, hit Rephrase. The output keeps the meaning but uses different vocabulary and structure — useful for non-native writers who want their sentences to read more naturally, or for anyone who needs the same idea phrased two different ways.

Summarise into 3 Sentences

The Summarize tab does what it says: takes any block of text and returns a 3-sentence summary. No bullet points, no preamble, just the gist.

The prompt is tuned to extract the load-bearing claims and drop the connective tissue, so the result reads like a competent skim. Good for articles, emails you don’t want to fully read, contracts you should fully read but won’t, and academic abstracts.

PDF to Text Extraction

Upload a PDF, get the text out. Built on PDFKit so it works with any PDF that has a real text layer (most modern PDFs do). The extracted text lands in a screen where you can copy it, save it, or feed it back into the Rephrase or Summarize tabs.

Textrix PDF-to-text extraction with output ready to copy or save

The classic use case: someone emails you a 12-page PDF and the part you actually need is a single paragraph in the middle. Extract, summarise, done.

The Workflow That Stitches It Together

The three tabs aren’t isolated. The most common path is:

Upload PDF → extract text
Summarise the extracted text into 3 sentences
Rephrase the summary in another language if you need to forward it on

The whole loop takes under a minute on the phone, which is the point. The desktop alternative is opening three different web tools, copy-pasting between them, and probably leaving a tab open you’ll forget to close.
