What Writing Studio does best
Sources you can open and check
Highlight a claim and Writing Studio finds a source that backs it, shows the exact passage, and rates how strongly it supports what you wrote. Each citation you add this way keeps that passage.
Search results with the passage that matches your claim.
One workspace from first source to final draft
Bring your sources in, write with an AI that has read them, review the draft, then cite and export. Nothing lives in a separate tool.
Every source you save, cite or upload, checked against its record.
Open about AI use
Set AI rules on each document, add an AI use statement, and keep a Writing Receipt that shows how a document was written. This helps when your school asks how you used AI.
Writing history, with the Writing Receipt you can share.
Catches claims without a source
If no source supports a claim, Writing Studio tells you instead of citing it anyway. You find the gap before your reader does.
Your key, your choice of model
Use Claude, ChatGPT, Gemini or Grok with your own API key. AI features then don’t use your plan allowances. Citation checks still count.

Frequently asked questions
Is Writing Studio better than ChatGPT?
They are built for different jobs. ChatGPT is stronger as a general assistant. Writing Studio is stronger for academic writing, because every citation links to a real passage in a source you can open.
Is Writing Studio free?
Yes. The free plan includes unlimited documents, sources and citations, full export, and a daily allowance of AI help. No credit card is needed.
Which one is cheaper?
Both have a free plan. ChatGPT Plus is $20 per month. Writing Studio Plus is $29 per month, or $15 per month billed yearly, and Pro is $69 per month, or $35 per month billed yearly. The two cover different things, so compare what you need.
Which is better for citations?
Writing Studio finds the source for a claim, shows the exact passage and flags claims that nothing supports. ChatGPT does not list a built-in citation checker on its site, so you check each source yourself.
Does Writing Studio check for plagiarism or AI writing?
Not yet. Plagiarism checks are not part of Writing Studio, and AI detection is coming soon with GPTZero. ChatGPT does not list a plagiarism checker or AI detector on its site.

Writing Studio is a web workspace. You can export your work to Word (which opens in Google Docs), PDF or LaTeX. ChatGPT has web, iOS, Android and desktop apps, and extensions for Word and Google Sheets.
Can I import my Zotero or Mendeley library?
Yes. Export your library from Zotero or Mendeley as a .bib or .ris file and import it. A direct connection isn’t available yet. You can also upload PDFs.
Can I use ChatGPT inside Writing Studio?
Yes. You can add your own OpenAI key and use it in Writing Studio, or a Claude, Gemini or Grok key instead.
Does ChatGPT train on my chats?
ChatGPT’s pricing page says content may be used to train its models on individual plans, with an opt-out available. Check OpenAI’s privacy information for details.
Can I use both?

Does Writing Studio use my writing to train AI?
