Feature Comparison
Perkoon
Unlimited Peer-to-Peer (P2P) Transfers
This is the foundational, free-forever feature. Using WebRTC technology, Perkoon establishes a direct, encrypted connection between two browsers for real-time file transfer. Since the data never passes through Perkoon's servers, there are no file size limits, no mandatory sign-ups, and absolute privacy. This model is sustainably free because it incurs negligible infrastructure costs, passing the savings and freedom directly to the user.
Honest Encrypted Cloud Storage
For situations where the recipient is offline, Perkoon offers a paid cloud holding service. Files are encrypted on Perkoon's servers before storage. This feature is transparently priced to cover the actual costs of server maintenance and bandwidth, representing an ethical alternative to services that hide real costs behind data mining and privacy invasions.
Native AI & Automation Integration
Perkoon is architecturally prepared for the future. It exposes a dedicated JavaScript object (window.__perkoon) allowing AI agents and automation scripts to interact with the transfer service programmatically. This eliminates the need for unreliable screen-scraping, enabling machines to send, receive, and manage files as a native utility within automated workflows.
Simple CLI and Browser Tools
Complementing its web interface, Perkoon provides a straightforward Command Line Interface tool. This caters to developers, power users, and automated systems, enabling file transfers to be integrated into scripts, build processes, and backend operations, ensuring flexibility across different user environments and technical proficiencies.
Sourcicle
Personal Email Finder
Sourcicle partners with premier data providers to deliver the most accurate personal email finder on the market. This tool moves beyond guesswork, providing verified contact information directly within your workflow, eliminating the need for external, unreliable databases and saving countless hours of manual searching.
AI Outreach Assistant
Craft winning outreach messages directly from the browser extension using AI trained on real emails from proven success stories. This feature helps you generate personalized, compelling copy that resonates with candidates, dramatically improving open and reply rates without starting from a blank page every time.
Sourcer-centric Email Sequencing
This is automation refined to perfection—so effective it becomes a seamless, "boring" part of your process. Create sophisticated, trigger-based email sequences, handle replies intelligently with AI, and utilize built-in winning sequence templates designed for maximum response rates, all managed from a single dashboard.
AI-Powered Analytics & Reporting
Move beyond basic metrics like reply rates. Sourcicle's analytics provide deep, AI-driven insights into what's truly working in your campaigns, and can instantly generate client-ready reports. This transforms raw data into strategic intelligence, guiding your sourcing strategy's continuous evolution.
Use Cases
Perkoon
Sending Large Project Files to Clients
Freelancers and agencies can instantly send massive video edits, design prototypes, or code repositories directly to a client's browser without worrying about compression, split archives, or expired download links. The P2P transfer handles unlimited sizes with no account required from the client, streamlining professional delivery.
Asynchronous Collaboration Across Time Zones
When a team member is offline, a user can upload files to Perkoon's encrypted cloud storage. The recipient receives a notification and can securely download the files at their convenience, ensuring work continues smoothly without being constrained by simultaneous online presence or insecure email attachments.
Integrating File Transfer into Automated Workflows
Developers can use the CLI tool or AI API to automatically upload build artifacts, backup logs, or transfer processed data between services. An AI agent can be instructed to fetch a report and send it via Perkoon as part of a scheduled task, making file transfer a reliable, programmable step in a larger process.
Privacy-Conscious Personal Sharing
Individuals sharing sensitive documents, personal photos, or large media collections can use Perkoon's P2P mode for peace of mind. The direct browser-to-browser transfer ensures that no third party, including Perkoon itself, can access or scan the content, upholding a strong standard of digital privacy.
Sourcicle
High-Volume Technical Sourcing
For sourcers needing to build extensive pipelines for hard-to-fill tech roles, Sourcicle streamines the process. Quickly find personal emails for passive candidates on GitHub or LinkedIn, launch targeted, localized AI outreach sequences, and track campaign performance with precision, all without leaving the browser.
Agency Recruiters Managing Multiple Clients
Agency professionals can use Sourcicle to maintain a consistent, high-quality outreach brand for various clients. The AI assistant adapts tone, and the analytics provide clear, shareable reports on candidate engagement for each client, demonstrating tangible value and streamlining communication.
Mitigating LinkedIn Profile View Limits
Talent professionals fearful of "LinkedIn jail" from excessive profile viewing can use Sourcicle's email finder to source contact information without relying solely on LinkedIn's InMail system. This diversifies outreach channels and reduces dependency on a single platform, ensuring sourcing activities remain uninterrupted.
Building a Structured, Repeatable Sourcing Process
Teams looking to mature from ad-hoc sourcing to a scalable, documented function can implement Sourcicle as their core engine. The sequencing, templates, and analytics create a repeatable framework for candidate engagement, allowing for optimization and consistent results across the entire talent team.

Frequently Asked Questions
Perkoon FAQ
Is the P2P transfer really free forever?
Yes. The peer-to-peer transfer technology operates directly between user browsers. Since Perkoon does not use its own servers or bandwidth to facilitate the data transfer for P2P, the operational cost is effectively zero. Therefore, this service can be offered without charge indefinitely, with no hidden catches or data monetization.
What happens if the recipient is not online when I send a file?
If the recipient is offline, the P2P connection cannot be established. In this case, you can use Perkoon's encrypted cloud storage feature (a paid option) to upload the file. The file is held securely on Perkoon's servers until the recipient comes online and accesses their unique download link.
How does Perkoon ensure my privacy?
For P2P transfers, privacy is inherent; files stream directly between devices and are never stored on or accessible to Perkoon's servers. For cloud storage, files are encrypted on your device before being uploaded. Perkoon maintains a strict policy of no scanning, no selling of data, and no "corporate nonsense" regarding user files.
Can AI agents or scripts really use Perkoon without a browser?
Yes. Perkoon is built for automation. It provides a dedicated JavaScript API (window.__perkoon) on its web interface for AI agents to interact with programmatically. Additionally, a Command Line Interface (CLI) tool is available, allowing scripts and backend systems to initiate and manage file transfers directly, enabling full integration into automated pipelines.
Sourcicle FAQ
How does Sourcicle prevent "LinkedIn jail"?
Sourcicle helps you diversify your outreach strategy beyond LinkedIn InMail. Its primary tool is finding personal email addresses through partnered data providers, allowing you to contact candidates directly via email. This reduces your reliance on LinkedIn's internal messaging system and its associated usage limits, lowering the risk of account restrictions.
Is Sourcicle a replacement for an ATS (Applicant Tracking System)?
No, Sourcicle is designed to be a powerful sourcing and initial outreach companion that works alongside your ATS. It focuses on the "top of the funnel" activities: finding candidates, making initial contact, and nurturing early engagement. Successful candidates can then be seamlessly moved into your ATS for further interview and hiring process management.
What makes Sourcicle's AI outreach different from a basic email template?
Sourcicle's AI is trained on real, successful outreach emails from expert sourcers, not just generic templates. It helps you generate personalized messages that consider context and can adapt tone for localization, moving past robotic translation to create culturally relevant messages that feel natural and human-written.
How quickly can I get started with Sourcicle?
