Real fixes from the editor

What Diglot actually changes

  • Before We have discussed about this problem

    After We discussed this problem

    "discuss" takes no "about"

  • Before the team is lack of resources

    After the team lacks resources

    wrong word form

  • Before the first version of the report until Wednesday

    After the first version of the report by Wednesday

    "by" for a deadline

Sentence rewrites

Not sure it sounds right? Compare three better versions

Select a sentence and pick a tone: standard, academic, formal, casual or concise. Your original stays until you choose.

  • Three versions side by side
  • Use, insert below or copy
  • Same meaning, more natural wording

Write in your language

Stuck on a sentence? Write it in your language first

Type the hard part in Spanish, Chinese or any language you think in. Diglot turns it into English right inside your document.

  • The rest of your English stays as it is
  • Use the translation, or insert it below
  • Keeps your terms with a personal glossary

Whole-draft polish

Polish the whole draft and approve every edit

Ask Cowriter to make a draft clearer or more formal. Removed words show in red, new words in green, and nothing changes until you accept.

  • Accept all, or review one edit at a time
  • Explains what it changed and why
  • Points out claims that may need a source

Essay check

Find every grammar slip in one pass

Diglot underlines each issue and lists it beside the text: what is wrong, why, and the fix.

  • "researches shows" to "research shows"
  • "which use" to "who use" for people
  • Fix one by one, or fix all

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 Transformer replaced recurrence with attention alone , and pre-trained encoders such as BERT carried the idea to language understanding . Attention mechanisms first improved neural machine translation .

We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely.

Your first language

The slips your first language puts in your English

Choose your language group. A generic checker fixes the sentence; Diglot also names the habit behind it, so it stops coming back.

  • 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.

FAQ

Questions, answered

What can I check with Diglot?

You can review grammar and wording in your own English text, translate passages, and compare alternative phrasing. Suggestions are generated with AI and can be wrong, so review them before using them.

Is Diglot only for students?

No. You can use the editor for your own emails, reports, articles, and academic drafts. Choose the wording that fits your reader and purpose.

Do I need an account?

Yes. The button on this page opens free account registration, then you can start working on your draft. No credit card is required for the Free plan.

What does the Free plan include?

The Free plan includes limited grammar, translation, and rewriting usage. Check the pricing page for the current quotas. A paid plan is optional if you need higher limits.

Does Diglot replace English lessons or human review?

No. It is a writing and editing tool. Use explanations as a starting point, and ask a teacher, colleague, or editor when meaning or specialist terminology is uncertain.

Will a rewrite always preserve my meaning?

No automatic rewrite can guarantee that. Compare the proposed text with your original, especially names, numbers, technical terms, and qualifications. Accept only the changes you want.
