If you're looking for a platform that integrates ChatGPT with a Chrome Extension for auto-filling posts and comments on popular websites, DapperGPT is a great option. It has a clean interface and a range of powerful features, including a Chrome Extension for auto-filling posts and comments. The extension is free to use with a valid OpenAI API Key, and premium features can be purchased with a one-time payment or yearly subscription.
Another great option is HARPA, a Chrome extension that uses AI models like ChatGPT to automate web tasks. It has over 100 web-aware commands across a range of tasks, including content generation and web scraping. HARPA runs on your computer, which means it doesn't send your data to the cloud, so it's a good option for automating web tasks.
For a more integrated experience with web pages, QuickyAI transforms any webpage into a ChatGPT interface. It supports custom prompts and one-click content summarization, which is useful for tasks like answering emails and rewriting paragraphs. The extension works with major browsers and supports GPT-4 and GPT-4 32k models, so you get strong AI abilities.
