Overview of Each Tool
ChatGPT Writer is a privacy-focused browser extension designed to automate the writing of emails and messages. It integrates directly into platforms like Gmail and LinkedIn, allowing users to generate high-quality replies or original messages based on a few keywords or the context of an existing conversation. It is built for efficiency, acting as a personal writing assistant that lives inside your browser's text fields.
ShareGPT is a simple yet powerful extension that solves a common problem: the difficulty of sharing a full ChatGPT conversation with others. With a single click, it generates a permanent, shareable URL for your entire chat log, preserving the formatting of both your prompts and the AI's responses. Beyond just sharing, it features a community "Explore" page where users can browse and learn from the most interesting conversations shared by others.
Detailed Feature Comparison
The fundamental difference between these tools lies in their placement within your workflow. ChatGPT Writer is an input tool. When you are in Gmail or LinkedIn, you click the extension icon to generate text. It reads the email you are replying to and drafts a response that matches the tone and context. It supports all languages and works on virtually any website, making it a versatile tool for anyone whose job involves heavy digital communication.
In contrast, ShareGPT is an output tool. It adds a "Share" button directly into the ChatGPT interface. Instead of manually copying and pasting text or taking multiple screenshots of a long conversation, ShareGPT hosts the conversation on its own website. This is particularly useful for developers sharing code solutions, teachers sharing logic puzzles, or prompt engineers showing off their latest "jailbreaks" or complex workflows.
From a privacy perspective, ChatGPT Writer emphasizes that your data stays private and is only used to generate the requested text. ShareGPT, by its very nature, is designed for public or semi-public sharing. While you can share links privately, the tool is often used to contribute to the public knowledge base of how people interact with LLMs. In fact, ShareGPT data has historically been used to train open-source models like Vicuna, highlighting its role in the broader AI ecosystem.
Pricing Comparison
- ChatGPT Writer: Operates on a freemium model. The free version offers a generous amount of usage, but power users who need "Unlimited" generations and access to the latest models (like GPT-4o) typically need to subscribe to a Pro plan, which usually ranges from $14 to $19 per month.
- ShareGPT: This is a completely free, open-source project. There are no subscription tiers or limits on how many conversations you can share. Users can contribute to its development on GitHub, and the hosting of shared links is currently provided at no cost to the user.
Use Case Recommendations
Use ChatGPT Writer if:
- You spend hours every day replying to emails in Gmail or Outlook.
- You are a recruiter or salesperson reaching out to prospects on LinkedIn.
- You want to improve the professional tone of your messages without leaving your browser tab.
Use ShareGPT if:
- You want to show a friend or colleague a cool or funny response you got from ChatGPT.
- You are a developer who needs to share a complex debugging session with a teammate.
- You want to bookmark and archive your most valuable AI conversations for future reference.
Verdict: Which One Should You Choose?
Because these tools perform different tasks, the "winner" depends entirely on your needs. If you are looking to increase your productivity and automate your writing, ChatGPT Writer is the superior choice. It is a dedicated utility for getting work done faster.
However, if you are looking for a way to collaborate or document your AI journey, ShareGPT is an essential, lightweight tool that every ChatGPT power user should have installed. Since both are browser extensions and do not conflict with one another, most users will actually find the most value in installing both: use ChatGPT Writer to draft your messages, and use ShareGPT to save the most interesting prompts that led to those drafts.
