BitPull 是一款面向开发者的免费桌面应用（macOS、Windows、Linux）。它通过 MCP 与 Claude Code、Codex、Cursor 等 AI 工具共享代码知识，并共享计算能力：CPU、内存和开放 AI 模型。使用他人的资源需要消耗积分；出借自己的资源可以赚取积分。

您的 AI 可以找到他人已经编写、签名并描述过的代码，并且只读取需要的文件，因此消耗更少的 token。摘要、测试或日常修改等简单任务可以交给社区电脑上的开放 AI 模型完成。

安全。任务以端到端加密方式到达，并在无法访问互联网和您文件的沙箱中运行。由您决定何时出借、出借多少以及出借什么，并可设置每日、每周和每月上限。在您开启之前，出借始终处于关闭状态。

使用网络只需安装 BitPull 应用。出借 CPU 和内存还需要 Docker 或 Apple Container；出借 AI 模型需要 Ollama，或由 BitPull 自动安装的图像、语音和音乐引擎。应用会显示您电脑上哪些是必需的、哪些是可选的。

使用他人资源时消耗积分，他人使用您的资源时您获得其花费的 80%。我们提供免费方案，Base（每月 4.50 欧元）和 Pro（每月 9.90 欧元）方案包含更多积分和优先级；您也可以充值。

可以。AI 助手可在 bitpull.cloud/llms.txt 和 bitpull.cloud/install.json 找到所需的一切，包括经过校验的安装程序以及必需和可选组件列表。BitPull 已收录于官方 MCP 注册表：“npx -y bitpull mcp”可将其连接到 Claude Code、Codex、Cursor 等工具，登录由您在网站上批准。

原因： The master switch "Lending on" is off (Pause / Resume only pauses lending that is already on), or a rule blocks lending right now: computer in use (idle minutes), on battery, outside the chosen hours, a daily/weekly/monthly limit reached, or almost no memory offered.

1. In "Lending rules" tick "Lending on" and press "Save rules".
2. Set "Only after minutes of inactivity" to 0 to lend while you use the computer.
3. Offer enough memory: "Max memory (MB)" is in megabytes, e.g. 4096 = 4 GB.
4. Read the line under the lending status: it says what the network sees or why nobody can use the computer.
5. From a terminal or an AI assistant: bitpull status, then bitpull set enabled=on idleMinutes=0 maxMemoryMb=4096

提示信息： Lending is switched off, Lending resumed, 0 lending now

已在 BitPull 中修复： 0.1.10 shows the reason in the app

原因： Lending is on, but this computer has neither a working sandbox (Docker or Apple Container passing BitPull's isolation check) nor an AI model to offer. The message continues with the exact reason.

1. Follow the reason shown after the message (the entries below cover the common ones).
2. Or download an AI model in "AI models to share" (models need Ollama or the built-in engine, not Docker).
3. Then press "Check again" in "Set up this computer"; BitPull also retries by itself every 5 minutes.

提示信息： Nobody can use this computer yet, docker: rejected

已在 BitPull 中修复： 0.1.13 retries a failed check every 5 minutes

原因： The Docker Hub account saved in Docker Desktop has expired credentials, so every image download fails, even of public images.

1. Open Docker Desktop, click your account (top right) and choose Sign out.
2. Sign in again, or stay signed out (public images download without an account).
3. On Linux run: docker logout
4. In BitPull press "Check again".

提示信息： failed to authorize: failed to fetch oauth token, 401 Unauthorized, Docker Hub login is no longer valid

原因： BitPull looked for Docker only in the default folder and in the PATH it had when it started; Docker installed later, elsewhere or per user was not found.

1. Update BitPull (Check for updates); version 0.1.8 or later finds Docker in every install location and re-reads the PATH.
2. Start Docker Desktop and wait until it is running, then press "Check again".
3. If BitPull shows a reason after "Docker" in "Set up this computer", follow it; the Windows user must be in the docker-users group.
4. In PowerShell: bitpull doctor shows what is detected and why.

提示信息： docker not found in PATH, not installed

已在 BitPull 中修复： 0.1.8

原因： Docker Desktop itself does not start, usually because WSL 2 needs an update, virtualization is off, or it needs a restart.

1. Restart the computer and wait 2-3 minutes for Docker Desktop (the whale icon stops moving).
2. Update WSL: open PowerShell as administrator and run: wsl --update ; then restart.
3. Open Docker Desktop and read its own error: e.g. "Virtualization support not detected" means enabling virtualization in the BIOS/UEFI.
4. Then press "Check again" in BitPull.

提示信息： Docker Desktop is unable to start, cannot download image busybox

原因： BitPull versions before 0.1.12 shared a temporary folder with Docker for each job; if file sharing was allowed, Docker kept those folders in its settings after BitPull deleted them.

1. Choose "Remove from configuration" (not "Create missing directories").
2. Update BitPull to 0.1.12 or later: jobs no longer share any folder with Docker, so this cannot happen again.

提示信息： shared folder invalid, one or more shared directories, Create missing directories, Remove from configuration

已在 BitPull 中修复： 0.1.12

原因： BitPull versions before 0.1.12 passed job files to Docker through a temporary folder of the computer.

1. Update BitPull to 0.1.12 or later: job files live in a Docker volume and no folder of the computer is shared.

提示信息： file sharing, Docker wants to access

已在 BitPull 中修复： 0.1.12

原因： BitPull's background service (bitpull-agent.exe) was still running and kept its file in use, e.g. after uninstalling.

1. Press Cancel, then in PowerShell run: Get-Process bitpull-agent, bitpull-desktop -ErrorAction SilentlyContinue | Stop-Process -Force
2. Run the installer again; if it still fails, restart Windows and run it first.
3. From 0.1.11 the installer stops the background service by itself.

提示信息： Error opening file for writing

已在 BitPull 中修复： 0.1.11

原因： A new version was being published and the package for this system was not ready yet.

1. Wait 15-20 minutes and press "Check for updates" again.
2. Since 0.1.12 releases become visible only when every system is ready.

提示信息： None of the fallback platforms, were found in the response

已在 BitPull 中修复： 0.1.12

原因： After an update or a restart the background service took more than 40 seconds to start, usually while Docker was still starting.

1. Wait a couple of minutes: the app retries every 30 seconds.
2. Or quit BitPull from its tray/menu-bar icon and open it again.
3. Update to 0.1.13 or later: the dashboard starts at once and slow checks continue in the background.
4. The details are in ~/.bitpull/agent.log (Windows: %USERPROFILE%\.bitpull\agent.log).

提示信息： The agent does not respond, agent.log

已在 BitPull 中修复： 0.1.13

原因： The current Lemonade engine needs to be told which hardware to use (graphics card or processor); BitPull did not send it.

1. Update the computer that lends the model to 0.1.14 or later and download the model again: BitPull now picks the best engine for that computer.

提示信息： both 'recipe' and 'backend' are required, engine install failed

已在 BitPull 中修复： 0.1.14

原因： Reasoning models (e.g. Qwen 3.5) could spend every token reasoning before answering; models running on a lender's processor are slow (a few tokens per second).

1. The computer that lends the model should run BitPull 0.1.14 or later: models answer directly.
2. Wait longer: bitpull set waitMinutes=20, or the "Wait up to" field in the app, or waitMinutes in the MCP tools.
3. A job that is still running is not lost: check it later (job_status).

提示信息： The model is still working, Model job running, empty answer

已在 BitPull 中修复： 0.1.14 (answers), 0.1.15 (adjustable wait)

原因： A sleeping computer is off the network. The screen turning off is fine; system sleep is not.

1. Keep "Stay awake while lending" on (0.1.15 or later): the computer does not sleep while it runs a job.
2. To lend all the time: Windows Settings > System > Power > Screen and sleep > When plugged in, put my device to sleep after: Never. macOS: System Settings > Battery > Options > Prevent automatic sleeping on power adapter when the display is off.

提示信息： offline

已在 BitPull 中修复： 0.1.15 keeps the computer awake during jobs

原因： Codes from bitpull login --device (or the bitpull_login tool) last 10 minutes and work once.

1. Run bitpull login --device again and approve the new code on bitpull.cloud/device while logged in.

提示信息： Code not found or expired, The code expired

原因： BitPull builds are not notarized (macOS) or Authenticode-signed (Windows) yet; the downloads are verified by SHA-256 instead.

1. Install with the script, which verifies the SHA-256 and avoids the macOS prompt: curl -fsSL https://bitpull.cloud/install.sh | sh
2. macOS from the disk image: right-click the app > Open, or System Settings > Privacy & Security > Open Anyway.
3. Windows: More info > Run anyway.

提示信息： is damaged and can't be opened, unidentified developer, Windows protected your PC
