Most “best ChatGPT Chrome extensions” listicles are affiliate dumps. This one is written by someone who builds one of them, so the bias is upfront: I’ll tell you exactly when ChatExport AI is the right pick and when something else is.
The category breakdown matters more than the rankings. Here are the five jobs ChatGPT Chrome extensions actually do.
1. Exporters — save conversations as files
The reason most people install a ChatGPT extension. You want a PDF, a Word doc, a Markdown note, or a Notion page from the chat.
Best free: ChatExport AI — disclosure: I built it. Eleven export formats, fourteen platforms (not just ChatGPT), 100% local processing, free tier with 5 exports/day. Notion sync and project export are Pro at $2.99/mo. No account required. Compared to alternatives →
Best for ChatGPT-only basic save: SaveGPT — one-trick PDF + Word exporter. Decent if ChatGPT is the only AI you use. Comparison →
Best open source: ChatGPT Exporter (pionxzh) — MIT-licensed, ChatGPT-only, four formats (PDF, MD, JSON, HTML), no Pro tier. If you want to read the source, this is the pick. Comparison →
Worth knowing about: Chat2Doc — five platforms (ChatGPT, Claude, Gemini, DeepSeek, Grok), PDF + Markdown free, Word and selective-message export gated behind Pro. Workspace-based — requires sign-up before the extension is usable. Auto-generated table of contents is a nice touch if you need it. Detailed comparison →
2. Prompt managers
Reusable prompt libraries. You write a prompt once, save it, recall with a slash command.
Best paid: AIPRM — large community prompt library, team folders, prompt versioning. Cluttered UI, but no real free competitor.
Best free / minimal: PromptBase Library extension — minimal prompt-recall, no community-prompt clutter.
This category is plateauing as ChatGPT’s own Custom Instructions and GPTs cover most of what these extensions originally provided.
3. Summarisers — webpage / video summarisers powered by ChatGPT
You’re on a long page or a YouTube video; you want a TL;DR via ChatGPT.
Best for YouTube: Glasp Chrome Extension or YouTube Summary with ChatGPT — both pull the transcript and prompt ChatGPT for a summary. Glasp adds annotation + social.
Best for arbitrary pages: WebChatGPT — adds web-search context to your prompts.
These tools are not the same as exporters. Don’t confuse “summarise this YouTube video” with “save my ChatGPT conversation”.
4. Sidebar augmenters — keep ChatGPT next to your work
Embed a ChatGPT sidebar on every page so you can ask without switching tabs.
Best free: Monica — solid free tier, sidebar with multiple model support.
Best paid: Merlin — more features, but the paid tier overlaps with paying for ChatGPT Plus directly.
If you’re already paying for ChatGPT Plus, an augmenter is duplicate cost — just open chatgpt.com in a sticky tab.
5. Code helpers
For developers who want ChatGPT context-aware on GitHub, Stack Overflow, etc.
Best for GitHub: Cursor (it’s a fork of VS Code, not technically a Chrome extension, but it covers this category in 2026 better than any extension does).
Best for Stack Overflow: ChatGPT for Search Engines — adds an answer panel next to SO results.
This category is shrinking — IDE-integrated AI has made browser code helpers redundant for serious work.
So which extension should you actually install?
Two-part answer:
- Export tool — pick based on platform breadth. ChatGPT-only? Open source matters? → ChatGPT Exporter. Use multiple AIs and want one habit? → ChatExport AI. Just need a quick PDF? → SaveGPT or even Chrome’s built-in print.
- One sidebar tool — only if you don’t pay for ChatGPT Plus. Monica is fine.
That’s it. Most other categories are either solved by ChatGPT’s built-in features (Custom Instructions, GPTs) or by IDE-integrated AI tools (Cursor).
