The whole document, not another isolated AI action.

Diglot replaces the overlap between a chatbot, translator, grammar checker and citation tool — for people who think in one language and publish in English.

AI Writing Assistant

Move from rough documents to clearer English drafts without jumping into a separate chatbot. Diglot keeps drafting, rewriting, and polishing inside the same document.

  • Start from a rough draft
  • Rewrite selected passages
  • Adjust tone to fit the audience
  • Keep document context while editing

AI Translator

Translate in context while you write, compare alternatives, and refine the final English output without leaving the page.

  • Translate words and full phrases
  • Compare translation options
  • Keep source meaning in view
  • Edit translated text immediately

Grammar Checker

Catch grammar, spelling, punctuation, and awkward translated phrasing as part of the drafting flow, not as a separate cleanup step.

  • Fix grammar and spelling inline
  • Improve clarity and sentence flow
  • Correct punctuation quickly
  • Review for business and academic English

Paraphrasing Tool

Rewrite awkward sentences, compare cleaner alternatives, and keep the version that best matches your meaning and tone.

  • Rephrase sentences and paragraphs
  • Keep the original meaning
  • Reduce repetition
  • Improve fluency in English

Autocomplete and Citations

Pause at the end of a sentence and Diglot suggests the next one in grey; Tab keeps it. Then cite the paragraph in APA, MLA, Chicago or any of 10,852 CSL styles.

  • Suggestions continue your own argument
  • /cite-paragraph adds in-text citations and the reference list
  • Real sources, looked up in a registry
  • Every insertion waits for your approval

Your Own PDF Library

Upload the PDFs you are writing from. /library answers from them, names the page, and drops the fact into your paragraph with the citation.

  • Answers come from your sources, not the open web
  • Page numbers stay attached to the quote
  • The citation lands in your paragraph
  • Review the edit before it is applied

Review Before You Submit

Run four checks at once: proofreading, source quality, citation gaps and a peer review of the whole draft, the way a careful reader would before you submit.

  • Major and minor issues across the whole document
  • Show in text jumps to the passage each comment is about
  • Fix it in the same editor, edit by edit
  • Peer reviews included on every plan

Deep Research

Ask a research question. Deep Research searches scholarly databases and your library, then writes a report with numbered references as a document in your workspace.

  • A report with the sources it used
  • Opens as a document you can edit and cite from
  • PubMed, arXiv, OpenAlex, Semantic Scholar and your library
  • 1 report a month on Free, 30 on Pro

Many researches shows that students which use social media more than three hours per day have lower grades. In our opinion this is because the constant notifications make difficult to concentrate, so the information is not stay in the memory.

The slips your first language puts in your English

  • Thank you for your comprehension

    Thank you for your understanding

    “Comprensión” is a false friend: in English it is “understanding”.

  • Actually, we use the old system

    Currently, we use the old system

    “Actualmente” means “currently”, not “actually”.

  • I assisted to the conference

    I attended the conference

    “Asistir a” means to attend; “assist” means to help.

Typical slips for each language group. Diglot flags them in your own draft and explains the habit behind each one.

A Stanford study (Liang et al., Patterns, 2023) found AI detectors falsely flagged 61% of TOEFL essays written by non-native English speakers.

Why Diglot fits bilingual writing better than generic AI tools

Diglot is built for people who think in one language and need to write clearly in English. Instead of forcing users to jump between a translator, a grammar checker, a paraphrasing tool, and a blank document, Diglot keeps the full writing workflow in one place.

Write, translate, and revise without leaving the same document

This matters most for non-native English speakers, ESL students, and multilingual professionals. You can draft ideas quickly, translate key phrases, improve grammar, and rewrite awkward sections without losing momentum or meaning.

Use AI help where it matters most

Diglot is especially useful when you need help turning translated thoughts into natural English. The AI writing assistant supports drafting and revision, while grammar checks and paraphrasing help make the final text clearer and more confident.

One app for drafting, translation, refinement, and citations

Instead of optimizing around one narrow function, Diglot supports the whole path from rough idea to finished document. That makes it useful for academic writing, client communication, content creation, and everyday English writing practice.

If you are comparing tools like QuillBot, Wordtune, or Grammarly, Diglot stands out by focusing on bilingual workflows and second-language writing instead of only polishing text that was already drafted in fluent English.

What is Diglot, and who is it for?

What is Diglot?

Diglot is an AI writing workspace for people who think in one language and publish in English. It connects smart search, drafting, translation, revision, citations, vocabulary and authorship evidence in one document.

Who is Diglot for?

It is built for non-native English speakers who write in English regularly — students, researchers, and professionals — rather than for native speakers looking for a general grammar checker.

Is Diglot the same as the diglot weave method?

No. The diglot weave method is a language-teaching technique that mixes words from a second language into text in your first language. Diglot is a writing application. The names are unrelated beyond the shared root.

Can Diglot help if an AI detector flagged my writing?

Diglot can issue an Authorship Certificate containing signed supporting evidence of how the document developed. It can help you explain your process, but no certificate can guarantee acceptance by a university, publisher or employer.

Do I have to write in English to use Diglot?

No. You can draft in your own language and publish in English, keeping translation and grammar review inside the same document rather than pasting between tools.

Is there a free version?

Yes. The Free plan covers the core bilingual workflow with limited word counts, so you can test how you actually work before deciding whether a paid plan fits.

publish in English
