Manus has attracted significant interest as a general-purpose AI agent capable of autonomous browser-based task completion. With that interest comes questions—about how the credit system works, whether it is safe to let an AI browse on your behalf, what tools it integrates with, and where the practical limitations lie.
This FAQ addresses the most common questions based on user reports, official documentation, and community discussions.
Note: Manus is actively evolving. Some details may change as the product updates. Always check the official Manus documentation for the most current information.
Credits and Pricing
How does Manus’s credit system work?
Manus uses a credits-based system where different tasks consume different amounts of credits based on complexity:
- Simple tasks (single-site research, basic data extraction): Low credit cost
- Medium tasks (multi-site comparison, form filling): Moderate credit cost
- Complex tasks (extensive research, many-step workflows): Higher credit cost
Credits are typically replenished on a daily or monthly basis depending on your plan tier.
How many credits do I get on the free plan?
The free plan provides a limited number of credits per day—typically enough for a few basic tasks. The exact allocation may vary and has changed over time. The free tier is designed for evaluation and light use, not production workflows.
Are credits consumed if a task fails?
This is a common concern. Based on user reports, credits are partially consumed for failed tasks—you are charged for the work the agent completed before the failure, but not for the full task cost. This is a reasonable approach but means that complex tasks that fail late in execution can still consume significant credits.
Can I buy additional credits beyond my plan?
Paid plans typically include a monthly credit allocation. Some plans offer the ability to purchase additional credits, though the per-credit cost may be higher than the bundled rate.
Is there an unlimited plan?
As of early 2026, Manus does not offer a truly unlimited plan. Even the highest tier has usage caps, though they are generous enough for most individual users. Enterprise customers may negotiate custom limits.
Security and Privacy
Is it safe to let Manus browse the web on my behalf?
Manus operates a browser session in a sandboxed environment. This means:
- The browser session is isolated from your personal computer
- Manus does not have access to your local files or other applications
- Browsing activity occurs in Manus’s infrastructure, not on your machine
However, there are legitimate security considerations:
- If you provide login credentials for websites, those credentials pass through Manus’s systems
- Any information Manus accesses during browsing is processed by the agent
- The browsing session may interact with websites that track visitors
Should I give Manus my login credentials?
This depends on your risk tolerance and the sensitivity of the accounts:
- Low-risk accounts (public review sites, general shopping): Generally acceptable
- Medium-risk accounts (social media, non-financial services): Use with caution, consider the implications
- High-risk accounts (banking, financial, email, healthcare): Not recommended without thorough security evaluation
A practical approach: use Manus primarily for tasks that do not require authentication. When authentication is needed, consider creating dedicated accounts with limited permissions.
Does Manus store my browsing data?
Manus processes browsing data to complete tasks. Their data retention policy should be reviewed on the official site, but in general:
- Task inputs and outputs are stored for your history
- The specific browsing activity (pages visited, data extracted) is processed during the task
- Data retention periods vary by plan tier
Is Manus SOC 2 compliant?
Enterprise security certifications like SOC 2 are important for organizational use. Check the official Manus security page for current compliance certifications. As a relatively new product, these certifications may still be in progress.
Can my employer see what I use Manus for?
On individual plans, your usage is private between you and Manus. Enterprise or team plans may include administrative visibility and audit logging.
Features and Capabilities
What types of tasks can Manus handle?
Manus is designed for web-based tasks, including:
- Research: Gathering information from multiple websites
- Data extraction: Pulling specific data points from web pages
- Comparison: Comparing products, services, or information across sources
- Form filling: Completing web forms and applications
- Monitoring: Checking websites for changes or updates
- Booking: Navigating reservation and booking systems
What can Manus NOT do?
Manus has clear limitations:
- Cannot access non-web applications: Desktop software, mobile apps (unless they have web versions)
- Struggles with CAPTCHAs: Automated CAPTCHA challenges are a common blocker
- Cannot handle complex authentication: Multi-factor authentication, biometric verification
- Limited with heavy JavaScript applications: Some modern web apps do not render cleanly for automated browsing
- Cannot make phone calls or send emails: Action is limited to browser interaction
- Cannot access paywalled content: Unless you provide credentials (with associated security considerations)
Can Manus take screenshots?
Yes, Manus can capture screenshots of web pages during tasks. This is useful for verification and documentation.
How long can a single task run?
Task duration depends on complexity. Simple tasks complete in minutes. Complex multi-site research tasks may run for 15-30 minutes or longer. There are typically timeout limits to prevent tasks from running indefinitely.
Can I run multiple tasks simultaneously?
Concurrent task execution depends on your plan tier:
- Free tier: Typically 1 concurrent task
- Paid plans: 2-4 concurrent tasks depending on tier
- Enterprise: Custom concurrency limits
Integrations
Does Manus integrate with other tools?
Manus’s integration ecosystem is still developing. Current integration capabilities include:
- Output export: Results can be exported as text, tables, or documents
- API access: Available on enterprise plans for custom integrations
- Webhook notifications: Task completion can trigger webhooks
- File output: Generated reports and data can be downloaded
Can I connect Manus to my CRM, project management tool, etc.?
Direct integrations with specific business tools are limited. The most practical approach currently is:
- Manus completes web-based research
- You export the results
- You import into your target tool
API access on enterprise plans enables building custom integrations, but this requires development effort.
Does Manus work with Zapier or Make?
Zapier and Make integrations may be available through API or webhook connections, but native integrations are limited. Check the current integration directory on Manus’s website.
Can Manus send results to my email?
Basic notification and delivery features are available. Task completion notifications and result delivery options depend on your plan tier.
Reliability and Troubleshooting
How reliable is Manus for important tasks?
Reliability varies by task complexity:
- Simple, well-defined tasks: High reliability (85-95% success rate)
- Moderate multi-step tasks: Good reliability (70-85%)
- Complex, many-step tasks: Variable reliability (50-70%)
Always verify results for important tasks. Manus is a productivity tool, not a decision-making system. Human review remains essential.
What should I do if a task fails?
- Review the error report: Manus typically explains what went wrong
- Simplify the task: Break it into smaller sub-tasks
- Be more specific: Refine your task description with more explicit instructions
- Try again: Some failures are transient (page not loading, temporary site issues)
- Contact support: For persistent issues on paid plans
Why does Manus sometimes give incomplete results?
Common reasons:
- Website structure changes: A website layout update can confuse the agent’s navigation
- Dynamic content: Content loaded via JavaScript may not be visible to the agent
- Rate limiting: Websites may rate-limit or block automated access
- Timeout: Complex tasks may hit time limits before completion
- Scope creep: The task may be broader than anticipated, exceeding the agent’s capacity
Can I give feedback to improve Manus’s performance?
Most agent platforms, including Manus, accept feedback on task results. Rating task quality and reporting specific issues helps improve the system over time.
Best Practices
Getting the Best Results
- Be specific: Clear, detailed task descriptions produce better results
- Set boundaries: Define the scope of research, number of sources, and output format
- Use checkpoints: Let Manus check in at key points rather than running fully autonomously
- Start simple: Build complexity gradually as you learn the tool’s patterns
- Verify output: Always review results before acting on them
