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.
