Codex Overleaf Link

Codex Overleaf Link Empower Overleaf with Codex.

English | 简体中文 Chrome · macOS / Windows / Linux · Local Codex

Ask about the project, revise a passage, and review the result beside the PDF. Codex Overleaf Link brings a local Codex workflow into the Overleaf editor, with project context, model selection, and conversations in one place.

Interface captured on 2.5.0. A read-only review of the standard Overleaf example project.

Read, revise, and review in one workspace

Intent	Control	Result
Understand a section or investigate a problem	Ask	An answer grounded in the available project context, without writing to Overleaf.
Make a change to the paper	Auto	Changes are written back to the project and shown in the run record.
Review edits in Overleaf	Auto + Track	Text edits appear as Overleaf tracked changes.
Reverse a run	Undo changes	Eligible edits are restored and eligible newly created files are removed.

Undo also works after refresh. If a file was edited again afterwards, that file stays available for review; completed Undo steps are retained so a retry can focus on the remaining work.

Give the conversation the right context

Use @ or ＋ to attach project files, add @compile-log for a compile issue, or select text in the editor. Add to Chat provides context; Edit Selection sets the requested edit range. PDFs and images can be attached to the composer as references.

An unsent draft with two project files attached. File context remains visible in the composer.

Follow the work and open a subagent's conversation

A run keeps its activity and result together. Expand its timeline to inspect reads, commands, and edits. With Parallel Subagents enabled, the main agent can continue working while delegated readers or workers run alongside it. Open a worker card to read that conversation, then return to the main task.

The same real task, shown as an activity view and as a child conversation. These captures show completed workers. Parallel Subagents is experimental.

Write in My Style Experimental

Build a reusable writing-style skill from selected Overleaf projects and PDFs.

1. Open Settings → General & appearance → Writing style.
2. Choose references from projects or add text-based PDFs.
3. Generate the style, then enable it for the project. Add or change references and use Update style to refresh the skill.

The skill is intended to guide phrasing, rhythm, organization, and tone. Reference material supports the writing style; the current task supplies the paper's facts, results, and citations.

Reference selection and generation controls. No private writing samples are shown.

Bring the model that fits

Use the local Codex CLI's model catalog, choose a reasoning level in the composer, or configure a compatible provider in Settings → Models & connections.
