DeepSeek's appeal is pretty specific: strong reasoning at a fraction of the cost of the big-name models, which is exactly why people lean on it hardest for the prompts that actually need multi-step thinking — a tricky proof, a gnarly refactor, a "walk me through your reasoning" debugging session. Those are also the prompts most worth saving precisely, because the wording that reliably triggers DeepSeek's reasoning mode is not something you want to reconstruct from memory every time.
PromptDock is a free Chrome extension that fixes this directly inside chat.deepseek.com: save a prompt once, then type // in the chat box to insert it instantly — no tab switching, no digging through old sessions.
DeepSeek's chat interface gives you conversation history, and that's it. There's no separate space for a named, reusable prompt — the phrasing that reliably gets it into deep reasoning mode instead of a shallow surface answer, or the exact system-style preamble you use before pasting in a block of code.
So the default workaround is the usual one: a notes doc, a pinned message, a habit of just retyping the prompt pattern from memory and hoping you remember the phrasing that actually worked.
Here's the actual workflow, and it's the whole product in one sentence: open chat.deepseek.com, 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 folder, use the arrow keys, hit Enter, and the full prompt lands in the message box with your cursor positioned wherever you set it. Roughly two seconds from "I need that exact phrasing" to "it's in the box."
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 your best DeepSeek prompts aren't actually unique each time — they're the same reasoning-pattern with one or two details swapped. That's what PromptDock's {{variables}} templates are for:
Insert it with //, and PromptDock prompts you to fill in topic and concern before dropping the finished prompt into the chat box. One saved template now covers every reasoning task you throw at DeepSeek, instead of you re-deriving the exact wording that reliably triggers careful step-by-step output.
Most people using DeepSeek for its cost and reasoning strengths are still cross-checking output against ChatGPT or Claude, or reaching for Perplexity when a question needs live sources. Every other prompt-saving method — DeepSeek's own history, a bookmark, a notes doc — stays trapped in whichever tool you wrote it for.
Save a reasoning-prompt template once in DeepSeek, and it's already sitting there the next time you open Claude to sanity-check the same problem. For the fuller case on why this matters day to day, see our guide on reusing prompts across every AI tool, or the broader rundown of every way to save ChatGPT prompts — most of the trade-offs apply to DeepSeek too.
Prompts you write for DeepSeek often include real problem data — code you're debugging, figures from actual work, drafts you're reasoning through. PromptDock stores your entire library locally in Chrome's extension storage. There's no PromptDock account to create, no login screen, and no server your prompts get uploaded to.
<all_urls>.If privacy and pricing across the category are on your mind, our comparison of prompt manager alternatives and roundup of the best AI prompt managers in 2026 go through this in more depth — most competitors require an account and a recurring subscription; PromptDock requires neither.
Group prompts by project or problem type, and filter with tags when the palette list grows past a couple dozen.
Keep your daily-driver reasoning prompts at the top of the palette so they're the first thing you see.
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 DeepSeek reply worth reusing later — and save it in two clicks.
No network requests, no cloud dependency. The palette renders instantly because it's reading from local storage.

No subscription. Pay $19 once, keep Pro forever.
Not ready to install? Start with our free 50 ChatGPT prompts pack — most work just as well pasted into DeepSeek, and you can import the whole set into PromptDock in one click whenever you are. If you want the shortcut-first version of this pitch, see how the // slash command works across every supported AI site.
Stop re-deriving the same DeepSeek prompt. Install PromptDock, save your first prompt, and press // in DeepSeek — it takes less time than reading this sentence again. Add to Chrome — it's free →No. DeepSeek's chat interface keeps conversation history, but there is no separate library of named, reusable prompts you can search and insert into a fresh conversation with a shortcut.
Select any prompt text on chat.deepseek.com, right-click, and choose "Save to PromptDock" — or open the extension popup and add it manually. It's saved locally in Chrome, instantly available everywhere PromptDock works.
