Feature Comparison

Perkoon

Truly Free Peer-to-Peer (P2P) Transfers

This is Perkoon's cornerstone feature. It enables direct, browser-to-browser file transfers with no intermediary server. This architecture means there are absolutely no file size limits, no mandatory account creation, and complete privacy as Perkoon cannot access the data stream. The service is free in perpetuity because this direct transfer model incurs negligible infrastructure costs for the company, a cost-saving passed directly to the user.

Honest Encrypted Cloud Storage

For when the recipient is offline, Perkoon provides a paid cloud storage solution. The service is upfront about this being a paid feature, as it honestly covers the cost of running and maintaining secure servers. Files stored in the cloud are encrypted, providing a secure holding zone. This transparent "pay for what costs us" model contrasts sharply with services that offer "free" tiers subsidized by data mining.

Native AI & Automation Integration

Perkoon is built for the future of work. It features window.__perkoon, a dedicated JavaScript object that allows AI agents and automation scripts to interact with the service programmatically without resorting to unreliable screen-scraping techniques. This native design makes it a robust tool for developers and users who incorporate AI assistants into their workflows for seamless file transfer automation.

Simple CLI and Referral Ecosystem

Beyond the web interface, Perkoon offers a Command Line Interface tool for power users who prefer terminal-based operations. Additionally, it features a community-driven referral program. Users can share a unique link; when new users sign up and perform transfers, both the referrer and referee earn bonus cloud storage, creating a sustainable growth model that rewards the community.

Shiru Notes

Simple by Design

Shiru Notes boasts a minimalistic interface that prioritizes clarity and focus. With its distraction-free design, users can immerse themselves in their thoughts without the clutter of unnecessary tools or notifications.

Instant Save

Never worry about losing your ideas again. Shiru Notes automatically saves your work as you type, ensuring that every thought is captured in real-time without the need for manual saving or interruptions.

Private and Secure

Privacy is a key pillar of Shiru Notes. All notes are encrypted, meaning they are accessible only to the user. This feature provides peace of mind, allowing individuals to write freely without concern for external access.

Write with Intention

The editor within Shiru Notes offers a calm and inviting space for users to unleash their creativity. It functions like a blank canvas, encouraging thoughts to flow naturally, making the writing process feel effortless and fulfilling.

Use Cases

Perkoon

Sending Large Media Files Freely

Videographers, photographers, and designers can send massive project files, raw footage, or high-resolution image sets without worrying about arbitrary caps, compression, or expensive subscription tiers. The unlimited P2P transfer is ideal for collaborative creative work where large data packets are the norm and budgets may be tight.

Secure and Private Document Sharing

Legal professionals, journalists, or anyone handling sensitive information can utilize the direct P2P transfer for confidential documents. Since the data never passes through a central server and Perkoon cannot see the content, it offers a higher degree of privacy for one-time secure document exchange compared to traditional cloud services.

Automated Workflow and AI Agent Tasks

Developers and tech-savvy users can integrate Perkoon into automated pipelines. An AI agent could be programmed to automatically back up generated reports via the CLI or use the native API to fetch and process files uploaded by a client, all without manual intervention, streamlining complex digital workflows.

When you need to send a file to a colleague or client who isn't currently available online, you can use Perkoon's encrypted cloud storage. You upload the file, and Perkoon holds it securely, generating a link you can send. The recipient can then download it at their convenience, solving the common problem of asynchronous file sharing.

Frequently Asked Questions

Perkoon FAQ

How can P2P transfers be completely free?

P2P transfers are free because of the underlying technology. The files are streamed directly from the sender's browser to the recipient's browser without ever being stored on or routed through Perkoon's servers. This direct connection means Perkoon incurs virtually no bandwidth or storage costs for these transfers, allowing them to offer the service for free indefinitely.

What happens if the recipient is offline?

If the recipient is not online to receive a direct P2P transfer, Perkoon offers encrypted cloud storage as a solution. This is a paid feature. The sender can upload the file to Perkoon's secure servers, where it is held encrypted. A link is then provided that can be sent to the recipient for download at their convenience.

Can Perkoon see the files I send via P2P?

No, absolutely not. During a peer-to-peer transfer, the file data is encrypted and transmitted directly between the two users' web browsers using WebRTC data channels. Perkoon's servers only facilitate the initial connection ("signaling") but never have access to the actual file content, ensuring true privacy.

Is Perkoon compatible with AI agents and automation?

Yes, uniquely so. Perkoon is built with a native API for automation, exposed via window.__perkoon in the browser. This allows AI agents and scripts to interact with the service directly to initiate transfers or check statuses programmatically, eliminating the need for fragile and inefficient web scraping techniques.
