Windows · Your AI library, on every PC

Prompts and skills
you built at work,
ready at home.

Stop copy-pasting the same prompts, skills and snippets between AI tools and computers. Save them in JianHe once, sign in, and they sync to your other PC. AI agents like Codex and Claude Code search and use them directly through the jianhe CLI.

ACROSS DEVICES

One library,
every PC, every AI.

The prompts and skills you build up at the office work just as well on your home PC. Save them in JianHe once, and let sync and AI handle the rest.

01

Save it on your work PC

Create prompts and snippets from the floating ball as you go. For skills you already have, ask AI to run skill scan to find the skills in Codex and Claude Code on this PC, then import them into JianHe once you confirm.

02

Sync to the cloud automatically

With an account and VIP, JianHe syncs whenever you make a change, launch the app or open the floating ball. Even with the app closed, a Windows scheduled task keeps syncing.

03

Pick up on your home PC

Open the floating ball and copy what you need. Or let AI search your items, compose content with a prompt, or read a complete skill into its own Skills folder.

On your work PC · ask AI to runjianhe skill scan --jsonjianhe skill import "<skill folder>" --json
On your home PC · ask AI to runjianhe item search "weekly report" --jsonjianhe compose --prompt <id> --input-file notes.mdjianhe skill context <id> --json

WHAT'S INSIDE

From saving to using,
every step feels easier.

Save, organize, use. Every good item finds its way back into your real desktop work.

01 / AI takes over

Let AI fetch it for you

Copy the AI request template from “More” in one click and send it to Codex or Claude Code. AI can search and read your prompts, skills and snippets, compose with prompts directly, and check skills before importing them into JianHe.

02 / Library

Keep what you use most

Prompts, skills and snippets each have their place. Categories, ratings and search help you find what you need fast.

03 / On your desktop

Always at hand while you work

Drag the floating ball anywhere and it snaps to the screen edge. Press Ctrl + Shift + Space to summon it, pick a prompt, enter your text, then compose and copy in one click.

HOW IT WORKS

Three steps to put AI in charge of your library.

From install to handoff, it follows the way you already work.

01

Install JianHe

During setup, tick “Add JianHe CLI to user PATH”. No admin rights needed. Once installed, the floating ball on your desktop is where everything starts.

02

Turn on AI CLI access

Turn on the switch under “More → AI CLI access” in the floating ball so AI can read items and import skills. It’s off by default.

03

Hand the request to AI

Copy the request template from “More → AI & Skill setup guide”, send it to Codex or Claude Code, and let it do the rest.

MADE FOR YOUR DESKTOP

Portable without sync.
AI access, with boundaries.

◌

No VIP? You can still move

A .jianhe transfer file carries everything offline: prompts, complete skills, snippets, categories, ratings, order and settings. No account needed, and it works between Windows and Android.

⌘

Clear security boundaries

AI CLI access stays off until you turn it on. When AI reads a skill, JianHe never runs its scripts automatically, and settings like hotkeys and CLI permissions stay on this PC.

COMING SOON · JianHe Community

Great prompts
shouldn’t stay
on one PC.

The JianHe Community is in the works. Once it launches, you’ll be able to discover prompts and skills others share publicly and save them to your JianHe in one click, or share the ones you’ve polished yourself.

  • ⌕
    DiscoverBrowse public prompts and skills by scenario and tag, and stop rewriting the same prompts from scratch.

FAQ

Before you download.

Which systems does JianHe support?

The current installer is for 64-bit Windows 10/11. Installers for other desktop platforms aren’t available yet.

Is the app available in English?

Yes. Since version 0.1.8 the desktop app and the cloud console are available in English. Pick English in the installer, or switch any time under More → Language.

What do I need for cross-device sync?

A JianHe account with VIP. Sync covers prompts, complete skills, snippets, categories, ratings and order; hotkeys, CLI permissions and usage history stay on each PC. After VIP expires, you can still sync cloud content down to your PC, but new content is no longer uploaded. With VIP you can also open the cloud console in your browser to view and organize synced items.

Can I use it without an account?

Yes. JianHe’s local features don’t need an account, and you can export a .jianhe file to move all your data between PCs offline.

Which AI tools are supported?

jianhe is a standard command-line tool, so any AI agent that can run terminal commands can use it. skill scan finds the Skills folders of Codex and Claude Code automatically; point it anywhere else with --root.

What can AI do with JianHe?

Search and read prompts, skills and snippets, compose content with prompts, read complete skill packages, and import new skills into JianHe. Prompts and snippets currently have to be created in JianHe itself. After you revise a skill, just ask AI to import it again; the new version is saved as a separate skill.

When will the JianHe Community launch?

The community is in preparation. Once live, you’ll be able to browse, save and share public prompts and skills. Final features and timing will be announced on this page.

Will AI automatically run scripts inside skills?

No. JianHe only hands skill content to the AI. Whether any steps run, and with what permissions, is decided by the app the AI runs in and what you allow.

Why is there no main window after installing?

JianHe uses a floating ball on your desktop as its entry point. It docks to the edge of the screen and expands when you click it; you can also press Ctrl + Shift + Space to open the quick menu.

How do I verify the download?

The installer is named JianHe-Setup-0.1.12.exe. You can check it against the SHA-256 checksum file published alongside it. The installer isn’t code-signed yet, so Windows may show a security warning.

On your next PC,
your library is already waiting.
