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.

UndercoverGPT

Discreet Access

UndercoverGPT offers users discreet access to ChatGPT through cleverly designed cover websites. This feature allows users to navigate the tool without attracting attention, making it ideal for restricted environments.

Seamless Integration

The tool is designed to integrate seamlessly with daily activities, ensuring that users can access AI assistance while continuing their work or studies without interruption.

Enhanced Productivity

By enabling covert access to ChatGPT, UndercoverGPT significantly enhances users' productivity. Individuals can obtain information, generate ideas, and solve problems more efficiently without the fear of being caught.

Privacy and Security

UndercoverGPT prioritizes user privacy and security. It employs robust measures to ensure that all interactions remain confidential, giving users peace of mind while they access the tool.

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.

UndercoverGPT

Academic Research

Students can utilize UndercoverGPT for academic research without the risk of being penalized for using AI tools in restricted settings. This allows them to gather information efficiently and enhance their academic performance.

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.
