What our research says

ChatJourney

ChatJourney is a small, free browser extension that fixes one real annoyance, ChatGPT's flat, hard-to-search conversation list, by laying past chats out as a visual timeline. It's a one-person open-source project rather than a company, so there is no paid tier, no support team, and no guarantee of continued maintenance.

Pros

  • Free and ad-free with no account or payment required beyond the ChatGPT login it reads from
  • Processes chat history locally rather than uploading it to a separate server
  • Open-source code is publicly viewable rather than a closed black box

Cons

  • Built and maintained by a single independent developer, with no company or support team behind it
  • Limited to ChatGPT; does not cover other chat assistants

Sider

Sider puts a chat panel on top of whatever page you're on, so you can ask about an article or PDF without copying it into a separate tab. The catch is that heavier use beyond the free daily cap needs a paid tier, and pricing quoted across review sites is inconsistent, so the entry price is worth confirming before committing.

Pros

  • Works as a sidebar on any web page rather than a separate chat tab
  • Routes one prompt to several models (GPT, Claude, Gemini, DeepSeek, Grok)
  • Ships native apps for iOS, Android, Windows, and Mac plus browser extensions
  • Can chat with PDFs and YouTube videos, not just plain text

Cons

  • Free tier is capped at a small number of daily uses
  • Independent pricing write-ups disagree on exact plan costs depending on where you check
  • No public API for developers

Which one fits

Choose ChatJourney if you need

  • Heavy ChatGPT users with long conversation histories who need faster navigation
  • Anyone wanting a free, local-processing tool rather than one that uploads chat data elsewhere

Choose Sider if you need

  • Reading and summarizing long articles or PDFs without leaving the page
  • Comparing answers from several models in one panel
  • People who want one subscription instead of several separate chatbot logins
