Promptbook versus n8n

When to choose Promptbook

When the next step depends on what the agent finds. For example, give it rules for sorting nonstandard invoices and handling exceptions, and let it choose how to proceed.

When to choose n8n

When you want to see each step and branch, such as writing a new contact to your CRM and sending a notification. Add AI to the steps that need it.

Feature details

Self-hosting

PromptbookThe engine that runs and schedules agent work lives on your computer, company server or VPS under your control.

n8nn8n Cloud or your own n8n instance.

Runs with your computer off

PromptbookClosing the controls leaves work running. Shutting down the engine host stops it. An engine on a running server can continue.

n8nDepends on the instance and connected systems. n8n Cloud is independent of your desktop.

Where your data lives

PromptbookAgents, tasks and conversations stay in project files on your host, with an auditable Git change history. Git does not encrypt files or undo actions in external services; Wallet stays outside it.

n8nOwn instance database and files, or n8n Cloud

AI models

PromptbookClaude, GPT, Gemini, Qwen and other models through supported tools and extensible integrations, including local models depending on the adapter and task. You are not tied to one vendor. External models receive the inputs they need.

Scheduled tasks

PromptbookGive a team of agents an ongoing responsibility, goal and rules. The engine runs one-off and recurring tasks.

n8nPublished workflows started by schedules or events, with optional AI agent nodes.

Integrations

PromptbookA universal browser operates web apps much like a person, including services without a ready-made connector or API. Capabilities depend on access, permissions and each service’s restrictions.

n8nReady-made nodes, HTTP/API, MCP and custom code

Passwords and credentials

PromptbookWallet is an encrypted credential vault on your host, separate from Git. A protected integration fills verified sign-in forms without putting passwords in the agent’s context. Protection requires keeping Wallet isolated from agent tools.

n8nEncrypted credentials in the instance database; own key

Trust model

PromptbookZero Trust for the App–engine connection: working content is encrypted between endpoints, and neither the relay nor central backend decrypts it. External AI and tools receive authorized inputs; account and operational metadata remain separate.

n8nOwn instance or trust in n8n Cloud; TLS and access administration

Mobile and remote control

PromptbookUse the control App to assign work, follow chats and manage the project over an authenticated E2E connection to your own engine. The local Console has separate access on the engine host. Closing the App does not stop the operation.

n8nWeb UI; secure remote access yourself when self-hosting
