Feature Comparison
Perkoon
Truly Free Peer-to-Peer (P2P) Transfers
Perkoon's core feature is its unlimited, free P2P file transfer. When both sender and recipient are online, files are beamed directly from one browser to another without ever passing through Perkoon's servers. This means there are no file size limits, no mandatory sign-ups, and absolute privacy for your data. Because this method costs Perkoon virtually nothing to facilitate, they can offer it as a free service forever, with no hidden catches or data monetization.
Honest Encrypted Cloud Storage
For sending files to someone who is offline, Perkoon provides encrypted cloud storage as a paid feature. This approach is transparent: the free P2P model covers online transfers, while the paid cloud storage honestly covers the cost of running and maintaining secure servers. Your files are encrypted on their servers, providing a secure holding area until your recipient is ready to download, without pretense of it being free.
Native AI and Automation Integration
Perkoon is designed for the modern workflow by offering built-in tools for automation and AI agents. Through features like window.__perkoon, AI assistants and scripts can interact with the service programmatically without resorting to inefficient screen-scraping techniques. This makes it possible to integrate file sending and receiving into automated pipelines, agentic workflows, and custom tools seamlessly.
Simple CLI and Browser Tools
Beyond the web interface, Perkoon offers a Command Line Interface (CLI) tool, providing power users and developers with a fast, scriptable way to transfer files. The web service itself works optimally on modern browsers like Chrome, Edge, and Brave, with clear communication about any limitations on Firefox and Safari, ensuring a reliable experience across platforms.
Sourcicle
Personal Email Finder
Sourcicle partners with top data providers to deliver the most accurate personal email finder available. This feature allows you to locate direct, verified email addresses for candidates directly within your browser, eliminating the guesswork and unreliable data from free tools. It integrates seamlessly into platforms like LinkedIn, so you can find contact details without leaving the profile you're viewing, saving valuable time and increasing your outreach success rate.
AI Outreach Assistant
Craft winning outreach messages directly from the browser extension using proven templates from real sourcing success stories. This AI assistant helps you personalize emails at scale, suggesting compelling subject lines and body text that resonate with candidates. It moves beyond generic generation, using insights from actual high-response campaigns to improve your communication and boost engagement rates without starting from scratch every time.
Sourcer-centric Email Sequencing
This feature provides automation so reliable it's boring. You can create sophisticated, trigger-based email sequences, automatically handle replies with AI, and utilize pre-built, winning sequence templates designed for maximum response rates. It manages the entire follow-up process for you, ensuring no candidate falls through the cracks while allowing you to maintain a personalized touch throughout the automated campaign.
AI-Powered Analytics & Reporting
Go beyond basic metrics like open and reply rates. Sourcicle's analytics tell you what's really working in your campaigns. The AI generates insightful, client-ready reports that demonstrate your sourcing value with clear data. This allows you to analyze campaign performance, optimize your strategies based on actionable intelligence, and easily report results to stakeholders or clients without manual data compilation.
Use Cases
Perkoon
Sending Large Project Files to Clients
Freelancers and agencies can use Perkoon's free P2P transfer to send large video edits, design mockups, or code repositories to clients instantly. There's no need to compress files or upgrade to a "pro" plan just to bypass a size limit. If the client is unavailable, the secure cloud hold ensures the file waits for them.
Private Document Exchange
For lawyers, journalists, or anyone handling sensitive information, Perkoon's P2P mode is ideal. Since files travel directly between browsers and are never stored on an intermediary server, it provides a much higher degree of privacy and security for confidential documents compared to traditional cloud transfer services.
Automating Backup and Sync Tasks
Developers and IT professionals can leverage Perkoon's CLI and native automation APIs to build custom scripts. For example, you can automatically back up log files to a colleague's machine or sync generated reports directly from a server process to a team storage bucket, all without manual intervention.
AI Agent File Operations
When an AI agent needs to send a generated image, document, or dataset to a user, it can use Perkoon's built-in window.__perkoon interface directly. This allows AI assistants to perform file transfer tasks reliably as part of a larger automated workflow, instead of struggling with simulated clicks on a website designed for humans.
Sourcicle
High-Volume Candidate Sourcing
For sourcers needing to build large, qualified pipelines quickly, Sourcicle streamlines the process. You can research candidates on LinkedIn, find their personal emails instantly with the integrated finder, and add them to a targeted outreach sequence—all without ever switching tabs or risking LinkedIn restrictions. This use case is ideal for filling multiple roles simultaneously or building talent pools for future needs.
Running Personalized Outreach Campaigns
When you need to engage passive candidates with tailored communication, Sourcicle's AI Outreach Assistant and sequencing tools are vital. You can launch a multi-touch email campaign that feels personal, using localized messaging and smart follow-ups. The system handles the scheduling and tracking, allowing you to manage hundreds of personalized conversations efficiently and increase your response rates significantly.
Demonstrating ROI to Clients or Stakeholders
Recruiters and agencies need to prove their value. Sourcicle's AI-powered analytics automatically generate clear, professional reports that showcase key metrics and campaign effectiveness. Instead of spending hours compiling data, you can provide clients with immediate, transparent insights into sourcing activities, candidate engagement, and overall performance, building trust and justifying your service.
Avoiding LinkedIn Jail and Tool Fatigue
For professionals tired of juggling multiple expensive tools and living in fear of LinkedIn account bans, Sourcicle offers a consolidated solution. By performing key actions like email finding and data extraction safely within its own framework, it minimizes risky behavior that triggers restrictions. It replaces a stack of separate applications with one integrated assistant, reducing cost, complexity, and risk.

Frequently Asked Questions
Perkoon FAQ
Do you store my files?
For P2P transfers, your files never touch our servers; they go directly from the sender's browser to the recipient's. For cloud transfers (used when the recipient is offline), files are encrypted and stored temporarily on our servers to facilitate the delivery. We are transparent that this is the part of the service that incurs a cost.
Can Perkoon see what I'm sending in a P2P transfer?
No. In a P2P transfer, the data stream is established directly between the two browsers involved. Our servers only help set up the connection but cannot intercept or see the actual file data being transferred. We literally cannot see what you are sending.
Why is the P2P transfer free forever?
The P2P technology we use allows browsers to connect directly to each other. This process costs us very little in terms of server resources and bandwidth. Therefore, we can offer it for free indefinitely. We only charge for the cloud storage feature, which genuinely requires us to maintain and pay for server infrastructure.
What if the other person is offline?
If your recipient is not online to receive the direct P2P transfer, Perkoon offers an encrypted cloud storage option. You can upload the file to our secure servers, and we will hold it for your recipient to download at their convenience. This is a paid feature, and details can be found on our pricing page.
