Collaborative writing for researchers

Write with AI.
Still sound like you.

The twin drafts in your voice, grounded in the references you upload. Nothing enters your paper until you approve it.

Your voice, your references, your call.

Four things that keep you the author

A twin that learns your voice

Add writing you have already done. The twin builds a voice profile from it and drafts in that voice, not in a model's.

The twin proposes. You decide.

Every generation lands in a panel beside your text. Insert it, replace a selection, or discard it. The default is that nothing happens.

Grounded in your references

Upload the papers you cite. Drafting draws on them, and citations point at sources you chose.

Bilingual EN/AR, fully RTL

Switch the interface between English and Arabic at any time. Papers carry their own language and direction.

How it works

From your writing to your draft

  1. 1

    Add your samples

    Upload a few papers you have already written. Three or four is enough to work from.

  2. 2

    The twin learns your voice

    It reads the samples and builds a voice profile: sentence length, how you hedge, how you move between claims.

  3. 3

    Write with proposals you approve

    Ask for a paragraph. It arrives in graphite, beside your text. Insert it, replace a selection, or discard it.

Every generation is kept in history. Nothing enters your paper without your decision.

Why Writing Twin

Everything else makes you choose

What Google Docs gives you

Real-time co-authoring with people. No help writing a word of it.

What AI chatbots give you

A draft in its voice, cut off from your sources, and you alone with what it wrote.

Writing Twin is both

A live co-author and a twin that writes in your voice, grounded in the references you upload, with every proposal kept on the record.

What that looks like

Three moments from an actual paper

The results in Table 2 suggest a stronger seasonal effect than previous surveys reported. One explanation is sampling timing.

Both earlier studies collected data outside the monsoon window, which likely widened the apparent gap.

A proposal beside your text. Keep it, edit it, or discard it — nothing is inserted on its own.

FAQ

Before you sign up

What is Writing Twin?

An AI co-authoring tool that learns your own writing voice from samples you give it, then drafts alongside you — proposing text you review, edit and accept, rather than generating a finished piece in one shot.

How does the twin learn my voice?

From the writing samples you upload or paste in. The more it has read of your work, the closer its drafts get to sounding like you rather than a generic AI voice.

Is this ghostwriting — am I allowed to use it?

Writing Twin drafts with you, in your voice, and keeps a record of the collaboration between you and the twin on every paper. Whether and how you need to disclose AI assistance is set by your institution, publisher or examining body, and those rules vary — that decision is yours to make, using the authorship record as evidence of how a piece was written.

What's the pricing, and is there a trial?

A 7-day free trial, card required. After that, Starter is £11 a month or Researcher is £23 a month, both prices including VAT. Cancel any time from the billing portal.

What counts as a "twin action"?

A generation (the twin drafting or continuing your text) or an AI review — each counts as one action against your plan's monthly quota.

How do I delete my account?

About

Built for researchers who write in two languages

Writing Twin is built by Al Daim Digital, a UK software company, for researchers who write in English and Arabic.

The twin proposes, the author decides, and the record can prove it. For anything else, write to support@writingtwin.com.
