## Overview

GPT Text Replacer is a small Chrome extension built by the studio behind Onward! Games. It is aimed at a very specific workflow: you have text sitting in a web page field — a draft comment, a paragraph in a CMS, a support reply — and you want it rewritten without leaving the page. After entering your OpenAI API key, choosing a model and setting a system prompt, selecting text triggers the model and the extension writes the result back over your selection.

The point is friction. Most AI writing helpers force you to open a separate chat, paste your text, copy the answer and paste it back. This extension collapses those steps into a single selection and replace action inside the browser, which is handy for repetitive editing tasks.

Because it uses your own key, there is no recurring cost from the developer and no third-party service handling your text beyond OpenAI itself. The trade-off is a minimal feature set: there is no history, no multi-turn chat, no preset prompt library and no accounts. It is a single-purpose utility, and the current listing is quite old with a very small audience, so treat it as a lightweight personal tool rather than a maintained product.

## Pricing & Plans

Free extension. You must supply your own OpenAI API key and pay OpenAI directly for the tokens used; the developer sells no separate plan.

## Key Features & Capabilities

- **In-place replacement:** Select text on a page and have the extension substitute it with a GPT-generated version without copy-pasting between windows.
- **GPT-4 with GPT-3.5 fallback:** Choose the more capable GPT-4 model or the lighter, faster GPT-3.5 depending on the task and cost.
- **Custom system prompt:** Define the instructions that shape every rewrite, so tone, style and formatting stay consistent with your needs.
- **Own API key:** Runs entirely on your personal OpenAI key, so there is no subscription and no developer-side proxy in between.
- **Tiny footprint:** Around 25 KB, with no account required and no data collection declared by the developer.

## Primary Use Cases

- **Rewrite drafts in place (Writer):** Polish a sentence or paragraph directly in the field where it lives instead of shuffling text to a chat window.
- **Quick copy edits (Marketer):** Select and reformat selected copy across web forms and editors without leaving the page.
- **Improve customer replies (Support agent):** Rephrase an email or ticket reply you drafted in a browser-based inbox.
- **Explore alternate wording (Student):** Try alternative phrasings of a line to see what reads better, using your own prompt instructions.

## Strengths

- Replaces text directly in the page, avoiding copy-paste round trips
- Supports both GPT-4 and the cheaper GPT-3.5
- Configurable system prompt for consistent rewriting style
- Uses your own API key, so no developer subscription
- Very small and lightweight with no account needed

## Limitations

- Requires your own funded OpenAI API key
- No history, presets or chat interface
- Listing is old (2023) with an extremely small user base
- In-place rewriting can overwrite text, so results should be checked
