One Prompt Library That Works Inside ChatGPT, Claude, and Gemini — Without Tab Switching
The Prompt Architects Chrome extension puts your full saved library inside every major AI tool so you access the same structured prompts regardless of which model you're using.
Free to start · No credit card · No API key · Works in ChatGPT, Claude & Gemini
You're Not Using One AI Tool. You're Maintaining Three Separate Prompt Silos.
The typical AI power user doesn't rely on a single model. ChatGPT for fast drafts, Claude for long-form reasoning and document work, Gemini when the task connects to Google Workspace. Each tool is useful for something different — which is fine. What's not fine is that every tool has its own chat history, its own blank box, and no shared memory of the prompts that worked last time. You end up rewriting the same instructions in three places, with slight variations each time, getting slightly different results that shouldn't differ.
The per-tool silo problem compounds with team size. One person runs a prompt in Claude and gets a result they like. Another person runs what they think is the same prompt in ChatGPT and gets something different. The difference isn't always the model — sometimes it's the prompt. When prompts live in individual chat histories, there's no way to know whether you're running the same thing or a drifted version of it.
Copy-pasting from a separate prompt doc works, but it's friction — enough friction that most people don't bother, and enough drift happens between pasting and tweaking that the 'same' prompt isn't the same for long. A library that lives inside each AI tool, visible in the sidebar, doesn't require switching windows or pasting anything.
How to Use One Prompt Library Across ChatGPT, Claude, and Gemini
- 1
Install the Prompt Architects Chrome extension
Install from the Chrome Web Store — no API key required, no account setup before you start. The extension adds a sidebar panel that activates automatically when you open ChatGPT, Claude, Gemini, or Grok.
- 2
Build your library once
Save your best prompts in the Prompt Architects web app or directly from the extension sidebar. Organize them by category and name them by task rather than topic. The library you build is the one that appears in every AI tool's sidebar — there's no per-tool setup.
- 3
Insert prompts directly from the sidebar
When you're inside ChatGPT, Claude, or Gemini, open the Prompt Architects sidebar, search or browse your library, and click to insert a saved prompt into the active input field. You can adjust it before sending — the insertion is a starting point, not a locked template.
- 4
Enhance prompts on the spot
If you write a new prompt from scratch inside any AI tool, you can run the Prompt Enhancer directly from the extension sidebar without leaving the tool. The enhanced version inserts into the chat input. Your best results can then be saved to the library immediately, building your collection as you work.
Per-tool silos versus one shared library
Before
You have a strong content brief prompt in a ChatGPT thread from three weeks ago. You're working in Claude today. You open a new tab, find the ChatGPT thread after a minute of scrolling, copy the prompt, paste it into Claude, and make small edits. Later you realize the version you pasted was slightly different from the one you'd already refined.
After
You open Claude, click the Prompt Architects sidebar, search 'content brief', and insert the saved and tested version in two seconds. The prompt is identical to what you've used in ChatGPT and Gemini. No copying, no drift, no hunting through old threads.
The prompt is the same regardless of the AI tool. What changes is which model you send it to — and that difference is intentional.
What One Cross-Platform Library Changes
No per-tool prompt maintenance
You maintain one library, not three. Update a prompt in Prompt Architects and it reflects everywhere — ChatGPT, Claude, Gemini — without editing each tool's history or remembering which version is current.
Consistent output when you switch models
Running the same structured prompt across different AI tools lets you compare model output fairly. When the prompt is the variable, model differences are informative. When the prompt drifts between tools, the comparison is noise.
No tab switching during active work
The sidebar extension means your library is a click away inside the tool you're already using. Retrieving a saved prompt takes seconds, not the context-breaking detour of opening a separate window, finding the right document, and copy-pasting.
Works across text, image, and video prompts
Prompt Architects libraries support text prompts for ChatGPT, Claude, and Gemini as well as specialized image prompts for Midjourney and Ideogram and video prompts for Veo 3 and Kling. One place for every prompt format your work requires.

Questions About Using Prompts Across AI Tools
Can I use the same prompts in ChatGPT, Claude, and Gemini?
Yes, with minor caveats. Most well-structured prompts work across all three models without modification. Occasionally a prompt tuned for Claude's conversational style produces different output in ChatGPT, but the structural elements — role, task, format, constraints — transfer well. The Prompt Architects Chrome extension makes the same library accessible inside all three tools so you can test this directly.
How do I avoid rewriting my prompts every time I switch AI tools?
Save your working prompts to a Prompt Architects library instead of leaving them in chat history. The Chrome extension puts that library inside ChatGPT, Claude, Gemini, and Grok simultaneously. Switching models doesn't mean finding and copying your prompt again — it's already in the sidebar.
Which AI tool gives the best results — ChatGPT, Claude, or Gemini?
It depends on the task. Claude tends to perform well on longer documents and nuanced reasoning. ChatGPT is a strong general-purpose default and has broad plugin and tool support. Gemini is particularly useful when work intersects with Google Workspace. Most consistent approach: run the same structured prompt in the model that fits the task, rather than committing to one model for everything.
Does the Prompt Architects Chrome extension work inside ChatGPT and Claude?
Yes. The extension activates when you open ChatGPT, Claude, Gemini, or Grok and adds a sidebar panel with your full saved library and the Prompt Enhancer. You can browse, search, insert, and save prompts without leaving the AI tool's interface. No API key is required.
How do I sync my prompt library across multiple AI platforms?
Your Prompt Architects library is cloud-stored and appears in the extension sidebar on every platform automatically. There's no per-platform sync step. Install the extension once, build your library once, and it's available inside every supported AI tool from that point on.
Does Prompt Architects support image and video prompts as well as text prompts?
Yes. The library supports text prompts for ChatGPT, Claude, Gemini, and Grok, as well as image-specific prompt formats for Midjourney and Ideogram and video prompt formats for Veo 3 and Kling. All prompt types live in the same library and are accessible from the same sidebar.
One Library. Every AI Tool You Use.
Install the Chrome extension free — no credit card, no API key. Your prompt library appears inside ChatGPT, Claude, and Gemini immediately.
