editGPT is an AI proofreading and editing product that combines a Custom GPT inside the GPT Store with a free browser extension for Google Chrome, Mozilla Firefox, and Microsoft Edge. Built by Salar Bajo and published under the editgpt.app brand, the tool layers a Microsoft Word style track changes interface on top of ChatGPT so writers can see, accept, or reject every revision the model proposes. The Custom GPT was first published when the GPT Store opened in early 2024, while the browser extension predates it, having launched on Product Hunt on February 28, 2023.
Unlike a general purpose chatbot, editGPT is designed for one specific writing workflow: paste in a draft, ask the model to fix grammar, clarity, flow, or awkward phrasing, and then review the output as a marked up document rather than as raw rewritten prose. The Chrome extension reports approximately 40,000 active users and a 4.2 star average rating across 49 ratings on the Chrome Web Store, and the Custom GPT version has been used in more than 1,900 conversations on ChatGPT.
The editGPT browser extension was the original product. According to its Product Hunt launch, the Chrome extension first shipped on February 28, 2023, only a few months after the public release of ChatGPT. A second Product Hunt launch followed on December 22, 2023, after a major rewrite that added a richer track changes panel and additional editing modes. The developer initially described the project on Reddit as a way to turn ChatGPT into something closer to Grammarly, letting writers see exactly what the model had changed instead of comparing two blocks of text by hand.
When OpenAI opened the GPT Store to all paid ChatGPT users in January 2024, the team published a companion Custom GPT under the same name. The Custom GPT mirrors the extension's editing prompts so that users who do not want to install a browser add on can still interact with editGPT through the standard ChatGPT interface. The two products are designed to be used together, and the Custom GPT's first message instructs ChatGPT to remind users that the experience is best when paired with the browser extension.
The Chrome listing shows the extension at version 1.0.31, last updated on November 7, 2025, with a package size of about 54 KiB. The Firefox version, maintained on Mozilla Add-ons under the developer handle jiconaar, sits at the same version number with a package size near 51 KB and is licensed under the Mozilla Public License 2.0. Across review history the extension has needed frequent updates because ChatGPT's front end markup changes often, which can break the injected editGPT button until a patch ships.
The Custom GPT version of editGPT is a thin wrapper around GPT-4 that uses a short system prompt to focus the model on proofreading rather than open ended chat. The system prompt instructs the model to follow whatever proofreading instructions appear in the user's first message, and to fall back to a default of fixing awkward phrasing if no instruction is supplied. It also asks the model to append a reminder that editGPT pairs with the browser extension to every first reply in a thread, and contains a light hearted defense against prompt injection that tells the model to respond with a Fresh Prince of Bel Air style joke if anyone tries to extract the custom instructions.
The GPT exposes six conversation starters that match its main editing modes:
It does not ship with uploaded knowledge files, custom actions, or external API tools, so it relies entirely on GPT-4's native language ability. This makes it lightweight and fast but also means that, on its own, the GPT cannot show diffs or accept or reject changes; users get back a rewritten passage and have to compare it to the original by hand. The browser extension exists specifically to fill that gap.
The editGPT browser extension only activates on chat.openai.com and the newer chatgpt.com domain. After installation it injects an editGPT toggle near the message input field. When the toggle is enabled and a user sends a proofreading prompt, the extension intercepts the model's reply and renders it as a track changes view: deletions appear with strikethrough styling, insertions appear in a contrasting color, and the original wording remains visible alongside the suggested edit.
Users can then highlight any portion of the response and click an Accept or Reject button to commit or discard that specific change. A Reset button restores the entire passage to its original wording, a Show or Hide markup toggle switches between marked up and clean views, and a Clipboard button copies the current accepted version of the text to the system clipboard without any markup, so it can be pasted directly into another document. This workflow is modeled on the way Microsoft Word's track changes feature lets editors negotiate edits in shared documents.
The extension is implemented as a small content script. Public listings describe permissions limited to clipboard write access and reading data on chatgpt.com, and the developer's data disclosure on the Chrome Web Store states that editGPT does not collect or sell user data and does not transfer it for unrelated purposes.
In addition to its in browser workflow, editGPT supports importing and exporting Microsoft Word .docx files while preserving track changes. A user can upload a Word document with existing tracked edits and comments, ask editGPT to revise it, and then export the result as a .docx file in which the AI's edits appear as standard Word track changes. This lets the output drop into a normal editorial review pipeline, where a human editor can use Word's native Accept and Reject controls to finish reviewing the AI's suggestions. Document formatting such as headings, bold, and italics is preserved through the round trip.
The combined editGPT product positions itself as an AI proofreading assistant rather than a general writing chatbot. Public feature listings consistently mention the following capabilities:
| Feature | Description |
|---|---|
| Track changes UI | Marked up view of insertions and deletions inside the ChatGPT interface, with selectable Accept and Reject controls. |
| Multi level editing | Distinct prompts for grammar only, awkward phrasing, clarity and flow, and trimming, exposed both as conversation starters and as quick action buttons. |
| Custom prompts | Saveable user defined editing prompts so writers can store their own house style instructions. |
| Word import and export | Upload a .docx file, edit it through editGPT, and export back to .docx with AI edits represented as native Word track changes. |
| Multi language editing | Marketing materials advertise editing in 20 or more languages, with some third party reviews reporting up to 80 languages with automatic detection. |
| Project mode | Long form document support for essays, reports, and manuscripts on the paid plans. |
| Privacy posture | The Chrome Web Store data disclosure states user data is not collected, sold, or transferred for unrelated purposes. |
EditGPT does not advertise built in plagiarism detection or AI content detection tooling. The track changes feature is sometimes pitched as a way to demonstrate that a piece of writing went through a human review process, since each accepted edit is recorded in the document, but editGPT does not score text for AI authorship the way services such as GPTZero or QuillBot AI detector do.
The editGPT browser extension is free to install, and a free tier of the editing service exists alongside two paid plans. Pricing is published on editgpt.app and summarized by several third party review sites; exact monthly word allotments can shift as the product is updated.
| Plan | Cost | Word allowance | Notable features |
|---|---|---|---|
| Free | 0 USD per month | About 10,000 words per month with a per request cap near 600 words | Multi language proofreading, basic editing prompts, track changes UI |
| Pro | About 12 USD per month | Roughly 200,000 to 300,000 words per month | Custom prompts, suggestion panel, Word import and export, long form Project mode |
| Elite | About 25 USD per month | Up to 1,000,000 words per month | All Pro features plus bulk editing and team workflows |
The Custom GPT inside ChatGPT is itself free to use for any ChatGPT Plus subscriber, since GPT Store access is included with a paid ChatGPT subscription. Users who want only the in chat experience without Word integration or higher word limits can rely on the Custom GPT alone, while users who want the full track changes workflow inside ChatGPT need the browser extension and, for heavier use, an editgpt.app subscription.
Reviews of editGPT, both on the Chrome Web Store and on independent blogs, tend to share the same shape. Writers and editors who depend on the tool describe it as one of the more practical AI editing extensions because it lets them keep authorial control: every change is visible and reversible, which makes it less risky to apply to professional writing than a tool that silently rewrites entire paragraphs. Several reviewers specifically call out non native English speakers as primary beneficiaries, since track changes makes it easy to learn from the model's grammar and phrasing suggestions instead of just accepting them blindly.
The most common complaint is reliability. Because the extension is glued to ChatGPT's web interface, every significant front end change at OpenAI risks breaking the editGPT button or the markup overlay. Multiple Chrome Web Store reviews describe the extension going dark after a ChatGPT update and then returning a few days or weeks later once the developer ships a patch. Reviewers in mid 2025 flagged a similar break following the rollout of GPT-5, with the extension working again once a follow up release was published.
A second category of feedback concerns the tool's scope. Some users have asked for a Grammarly style real time underlining experience that flags issues as you type rather than only after a prompt is sent, and others have requested deeper stylistic rewriting beyond grammar, clarity, and flow. EditGPT's approach has remained closer to a one shot revision pass than to live in line suggestions, which keeps it lightweight but limits how it competes with full writing assistants such as Grammarly.
Product Hunt activity supports the picture of an actively maintained tool with a small but loyal user base. The original 2023 launch and the December 2023 relaunch together attracted more than 160 upvotes and a five star rating from a small number of reviewers, and the editgpt.app site continues to be updated with new feature pages such as the Word track changes landing pages.
EditGPT sits in a niche between general purpose chatbots and dedicated writing assistants.
| Tool | Primary interface | Strength | Limitation relative to editGPT |
|---|---|---|---|
| Grammarly | Standalone web app, browser extension, desktop apps | Real time inline suggestions across many websites | Does not run inside ChatGPT, and uses its own editing models rather than GPT-4. |
| QuillBot | Web app and extension | Paraphrasing, summarization, AI detection | Less focused on track changes review of model output. |
| ChatGPT alone | Chat interface | Open ended editing and rewriting | No diff view, so users must compare original and rewritten text by hand. |
| editGPT | Custom GPT plus browser extension | Track changes overlay on top of ChatGPT replies, Word import and export | Depends on ChatGPT's web UI; breaks when that UI changes. |
This positioning explains why editGPT has remained popular despite its occasional outages. For users who already pay for ChatGPT Plus and want a tighter editing loop without leaving the chat window, no other tool offers the same combination of in browser track changes and Word document round tripping.
