用 osFoundry 实现本地优先、私密且可离线的 AI

在设备上运行模型，将私密频道挡在云外，离线工作。您的数据，您的机器。

osFoundry 是本地优先的：一个在设备上运行模型的桌面应用，私密频道永不同步，并完全支持离线工作。端到端加密保护那些确实需要同步的内容。本地同步引擎将您的工作空间投射到文件系统中，评分和索引通过 osIndex 在设备端进行，无泄漏本地 LLM 模式保证任何提示都不会离开您的机器。

快速解答

本地优先桌面应用——离线可用，在线时同步。
私密频道永远不离开您的设备，绝无例外。
对所有需要同步的内容采用端到端加密。
无泄漏本地 LLM 模式——提供方中立，绝不走云端路由。
本地同步引擎——工作空间即您磁盘上的一个文件夹。

简介

Most AI products are cloud services with a desktop shell: your prompts, files, and history live on someone else’s servers, and “privacy” means a policy promise. osFoundry inverts that. The desktop app is the primary home of your workspace — the local sync engine projects it into your file system as ordinary folders and files, models can run entirely on-device, and cloud features are opt-in additions rather than the foundation.

Privacy is enforced at the architecture level, not the policy level. A private channel is excluded from the sync queue at creation — its messages and attachments are never uploaded, so there is nothing on a server to leak, subpoena, or misconfigure. The no-leak local-LLM mode applies the same idea to inference: it is a workspace-level switch that disables every cloud route, so no prompt can leave the machine regardless of which chat or agent sends it.

Everything that does sync — because you chose multi-device or team features — travels end-to-end encrypted with workspace-controlled keys. The result is a gradient you control: fully offline and local, selectively synced, or cloud-augmented, per workspace and per channel.

在 osFoundry 中如何操作

Flag what is private — Create a private channel for sensitive work. It is excluded from sync at creation — messages and attachments are never enqueued for upload, and other devices on your account cannot see it.
Go local for inference — Install a local model from the catalog, then enable no-leak LLM mode in workspace settings to disable all cloud routes for prompts.
Verify it yourself — Disconnect from the network and keep working — chat with local models, edit notes, run offline-capable Room Apps. Sync resumes for non-private data when you reconnect.

使用场景

Legal and back-office teams: Draft against contracts and HR documents with a local model in a private channel — nothing ever leaves the machines that hold the files.
Consultants under NDA: One private channel per client. Client material stays on-device while general research uses cloud models in normal channels.
Frequent travelers: Full workspace on a laptop: local models, notes, and apps work in flight; encrypted sync catches up on landing.

常见问题

Does osFoundry require a cloud account to use?

No. The desktop app runs locally with no sign-in required. Cloud features (sync, hosted GPU, public app URLs) are opt-in.

Can I work entirely offline?

Yes — install local models, disable cloud routes, and the app works without network access. Sync resumes when you reconnect.

How is "private channel" different from a normal channel?

A private channel is flagged at creation. The local sync engine never enqueues its messages or attachments for upload. Even other devices on your account can’t see it.

Which data leaves my machine in the default setup?

Only what you opt into. Private channels never sync. Non-private data syncs end-to-end encrypted when you enable multi-device or team features; local-model prompts never leave the device, and no-leak mode extends that guarantee to the whole workspace.

Can I mix cloud models with local privacy?

Yes — route sensitive prompts to local models (or keep them in private channels) while public-information prompts use cloud models. The routing is configurable per path in osStudio.
