What counts toward your AI use: Error Assist suggestions, AI assistant message exchanges, or an invocation of any language or generator tool (including accepting a suggestion).
If you reach your daily limit, a notification appears in the AI features. You'll see when your allowance resets and the option to upgrade your plan. AI access resumes automatically when the allowance resets—no action needed.
If you upgrade your plan, your allowance resets immediately to the new tier.
Where to find AI tools
AI tools appear in several places in the editor:
AI assistant: open from the left bar
Error Assist: appears in the error logs when a compile error is detected
Language suggestions: shown inline as you write; navigate with the toolbar controls when suggestions are active
Generators (equation, table, title, abstract, keywords): available in the Insert menu or via the TeXGPT button when nothing is selected
Rewrite tools and Synonyms (Paraphrase, Make concise, Make scientific, Split, Join, Translate): available from the AI action menu — open it via the robot/TeXGPT icon, or via the floating AI sparkle menu that appears when you select text. Available actions are filtered based on how much text you've selected
TeXGPT: a dedicated button at the far left of the main toolbar, before undo/redo.
Check citations: available from the AI action menu (robot icon or floating AI sparkle menu)
AI settings
All AI and language preferences now live in the Settings modal, split across two tabs:
Editor tab:
Toggle AI shortcuts on text selection
Toggle AI shortcuts on empty lines
Toggle sentence completion (requires accepting AI terms of service)
Turn the combined floating menu on or off
Spelling and language tab: choose your suggestion model — including the Writefull model — and manage language suggestion settings.
Enabling and disabling AI features
To turn off all AI features:
Go to Account settings and scroll to the Integrations section.
Select Disable AI features.
This turns off all AI tools in the editor, including Error Assist and language suggestions.
Who can use Overleaf AI
Overleaf AI features are available to all users. However, users whose accounts are managed by an organization, or whose institution has opted out of AI features, can't access the features. You will need to contact your local admin for more details.
Data and privacy
Some AI features send content to third-party services, including OpenAI. You'll be asked to accept the AI terms of service the first time you use a feature that involves external processing. Accepting once covers all AI features — you won't be prompted again.
Your data is never used to train AI models.
What gets sent for each feature:
Error Assist: the error message, relevant lines of code, and file names in your project
AI assistant: content from your project needed to answer your question; the assistant may also query third-party search engines
Language suggestions and rewrite tools: the selected text or surrounding context
Citation suggestions: citation data via Dimensions
For full details, see Overleaf's privacy notice and the list of third-party processors.
Troubleshooting
Can I undo an AI suggestion once applied? Yes — use Undo in the toolbar or Ctrl/Cmd+Z.
Why are suggestions sometimes incorrect? AI can misinterpret complex or custom LaTeX commands. Always review suggestions before applying them. The more specialised your LaTeX, the more likely you'll need to adjust a suggestion.
Why hasn't an AI fix worked for my error? Error Assist works best with errors that include a full error message in the logs. It won't show for code-check errors that appear as you type. See fixing LaTeX errors for more help.
Where did the Writefull toolbar go? It's been removed. Its tools moved into the main toolbar, the Insert menu, and the AI action menu — see Where to find AI tools above for exact locations.
Where did Summarize and Explain go? These actions have been removed and are no longer available.
I can't find the floating menu (add comment / tracked changes / AI actions). Check whether it's been turned off in Editor settings.
Where did Writefull's own settings go? They've moved into the main Settings modal, under the Editor and Spelling and language tabs.
