If you live in Claude for research, writing, or coding help, you've probably built up a mental folder of prompts that just work — the exact phrasing that gets Claude to write in your voice, the debugging prompt that always gets a clean root-cause answer, the outline structure your editor likes. The problem is that none of it lives anywhere. It's scattered across old conversations, a Notes app, or your own memory — and rewriting it from scratch is the tax you pay every single time.
PromptDock is a free Chrome extension that fixes this with one habit: type // in the Claude message box, and a searchable palette of your saved prompts opens right there. Pick one, it's inserted, you keep typing. No tab-switching, no copy-paste, no account required.
This trips people up because Claude does have Projects, and Projects do feel like they should solve this. They don't — not for prompt reuse. A Project stores background knowledge and instructions for one ongoing body of work (a codebase, a client, a book draft). Claude's Styles let you set a standing tone. Neither one gives you a library of discrete, named, individually reusable prompts you can insert on demand into any conversation.
So what actually happens in practice: you scroll back through old chats trying to find that one prompt from three weeks ago (Claude's search is decent but indexes conversations, not prompt snippets buried inside them), or you keep a running doc of prompts and copy-paste from it, tab-switching every time. Both work. Both also cost you real time, every day, forever — and neither one follows you when you also use ChatGPT or Gemini for other tasks.
This is exactly the gap a dedicated Claude prompt manager extension is built to close: a place to save prompts once, find them instantly, and insert them without leaving the chat box.
Here's the actual workflow, and it's the whole product in one sentence: open claude.ai, click into the message box, type //, and a small palette appears above your cursor listing your saved prompts.
Type a few letters to filter by name or tag, use the arrow keys, hit Enter, and the full prompt lands in the message box with your cursor positioned wherever you set it. The whole thing takes about two seconds — faster than remembering where you saved it, let alone retyping it.
Getting prompts into your library is just as low-friction:
A dedicated keyboard shortcut also opens the palette without typing the trigger characters, for anyone who prefers not to touch the mouse.
Most of the prompts people rewrite aren't actually unique each time — they're the same structure with one or two details swapped. That's what PromptDock's {{variables}} templates are for. Save a prompt like:
Insert it in Claude with //, and PromptDock prompts you to fill in language and concern before it drops the finished prompt into the chat box. One saved template now covers every code review you ever ask Claude to do — Python or Rust, performance or security — instead of you hand-editing the same paragraph from memory each time. The same pattern works for outline requests, tone-matching prompts, research briefs, or anything else where only a couple of words actually change between uses.
Most people using Claude seriously are also using at least one other model — comparing answers, using Gemini for something Google-specific, or falling back to ChatGPT for a particular plugin or GPT. Switching tools shouldn't mean losing your prompt library, so PromptDock doesn't scope it to one site. The exact same // trigger and the exact same saved prompts work across:
Save a prompt once, from any of those tabs, and it's instantly available with // in all the others — because the library lives in your browser, not inside any one site. For the fuller case on why this matters day to day, see our guide on reusing prompts across every AI tool, and if you want the full landscape of the category, how the best AI prompt managers of 2026 compare.
PromptDock stores your prompts in Chrome's own local extension storage, on your device. There is no PromptDock server your prompts get sent to, no sign-up flow, no email required to start. That matters more than it sounds: a lot of prompt libraries contain sensitive material by nature — internal process docs, client-specific instructions, draft strategy, code you're debugging. A 2026 privacy review of AI browser extensions found that over half collect user data of some kind; PromptDock's local-first design means there's simply nothing to collect.
<all_urls>.If you're evaluating whether a prompt manager extension is even the right approach versus a plain notes doc, our complete guide to saving AI prompts walks through every method honestly, including the trade-offs of each.
Group prompts by project or client, and filter with tags when the palette list grows past a couple dozen.
Keep your daily drivers at the top of the palette so they're the first thing you see, before you even type a filter.
Move your whole library in or out as JSON — useful for backups, or migrating from another tool or a notes doc.
Open the palette from anywhere in the page with a shortcut, no need to type // first.
Highlight any text on any page — including a Claude reply you want to reuse as a prompt later — and save it in two clicks.
No network requests, no cloud dependency. The palette renders instantly because it's reading from local storage.
Free starts you at up to 10 saved prompts, forever, no card and no account. Every fresh install also unlocks the full Pro feature set — unlimited prompts, templates, sync — for a 7-day trial, so you can decide with the real thing in hand rather than a stripped demo.
No subscription. Pay $19 once, keep Pro forever.
Stop retyping the same Claude prompts. Install PromptDock, save your first prompt, and press // in claude.ai — it takes less time than reading this sentence again. Add to Chrome — it's free →No. Claude has Projects and Styles, which store context and tone, but there is no native way to save a named prompt and re-insert it with a shortcut. That's the gap PromptDock fills.
Install PromptDock, save a prompt (typed in, imported, or captured with right-click → Save to PromptDock on any page), then open claude.ai and type // in the message box. A searchable palette opens right there; pick a prompt and it's inserted with your cursor ready to go.
Yes. PromptDock is one local prompt library that works the same way — type // — in Claude, ChatGPT, Gemini, Perplexity, DeepSeek, Grok, Microsoft Copilot, Mistral, Poe and Google AI Studio.
No. Prompts are stored locally in Chrome's extension storage on your device. There's no PromptDock account and no PromptDock server. You can export your library to a JSON file anytime for your own backup.
Yes — the free plan stores up to 10 prompts forever, no card required. Every install also unlocks every Pro feature (unlimited prompts, templates, sync) for a 7-day trial. Pro afterward is a single $19 one-time payment, not a subscription.
