Working with autonomous AI agents often involves a familiar cycle of trial and error. A user provides a prompt, the system begins building or researching immediately, and only later do mismatches in assumptions, missing details, or overlooked edge cases become clear.
The result is repeated revisions, wasted effort, and outputs that require substantial rework to align with the original intent.
Manus has introduced 'Plan Mode' as a response to this pattern.
According to a blog post, the feature allows the agent to pause and generate a structured plan before any building or execution begins.
Users activate it manually by typing a slash command on the web interface or selecting it from the plus menu on mobile. Once engaged, Manus evaluates the request, researches feasibility where relevant, and may ask clarifying questions if context is incomplete.
It then produces a Markdown document outlining goals, steps, constraints, and potential issues.
The plan remains fully editable.
Users can revise sections directly, request further adjustments from the agent, or iterate until the document matches their requirements.
Only after explicit confirmation does Manus proceed with the work. This ensures that no changes are made to existing projects, websites, applications, or other outputs until approval is given.
The feature can also be invoked mid-task, at which point the agent pauses current activity, prepares a plan for the next phase, and waits for confirmation before continuing.
Plan Mode is particularly oriented toward development and complex multi-step work.
It surfaces business logic conflicts, unstated assumptions, and edge cases early in the process, when corrections cost less than post-build fixes.
A single short sentence can serve as the starting point.
For instance, a request to build a landing page expands into details on audience, copy, components, and integrations. A request for a task manager with accounts and a database produces schema suggestions, authentication flows, and API structures. Updates to live sites or deployment steps similarly generate plans that highlight impacts and configurations before any action is taken.
The approach fits within a broader set of tools on the platform aimed at reducing iteration overhead.
These include the ability to roll back to earlier versions, copy sites for experimentation without risk, and use branches to explore alternative paths during planning.
Plan Mode itself does not activate automatically, preserving the option for quick, straightforward tasks to proceed without the extra step. It is available now across web and mobile for all users.
By separating planning from execution and placing confirmation under user control, the feature shifts the interaction model. Alignment happens in text before resources are committed to building, which can limit the frequency of misdirected work while still allowing the agent to expand incomplete ideas into comprehensive specifications.
