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.
The Ultimate Piano
Real-Time Chord Detection & Explorer
As you play freely on your connected keyboard, The Ultimate Piano instantly analyzes and displays the names of the chords you are creating. This real-time feedback is a transformative tool for understanding harmony in context. It demystifies chord progressions and helps you internalize how different notes combine, moving your knowledge from theoretical memorization to practical, hands-on understanding during improvisation or song learning.
Interactive Scale & Chord Trainer
Move beyond static diagrams with a fully interactive learning mode. Select from 14 different scale types or any chord, and the platform will instantly visualize it across the keyboard and even play it for you. The Scale Trainer provides detailed performance analysis, guiding your technique and accuracy. This feature structures your growth, ensuring you build a solid theoretical foundation and technical proficiency in a guided, progressive manner.
Integrated Multimedia Practice Players
Your practice evolves by playing with real music. The Ultimate Piano includes a MIDI player with falling notes, a standard audio player for MP3s, and a dedicated YouTube player. You can slow down any audio, set A-B loops to drill difficult sections, and watch notes light up in sync. This integration bridges the gap between isolated exercises and actual performance, allowing you to learn songs, play along with tutorials, and develop your timing and ear in a musical context.
Comprehensive Metronome & MIDI Recorder
Develop impeccable timing with a fully-featured metronome offering customizable time signatures, subdivisions, and a speed training function to gradually increase tempo as your skill grows. Complementing this is the built-in MIDI recorder, which captures every nuance of your performance. This allows you to track your evolution over time, analyze your playing, and export your creations to use in other digital audio workstations, marking clear milestones in your progress.

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.

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.
The Ultimate Piano
The Self-Taught Beginner's Foundation
A complete newcomer can start their musical evolution without feeling overwhelmed. They can use the computer keyboard or mouse to begin, with Kids Mode making it engaging for young learners.

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.
