Feature Comparison
Perkoon
Truly Free Peer-to-Peer (P2P) Transfers
This is the core of Perkoon. When both you and your recipient are online, files are beamed directly from your browser to theirs. The data never passes through Perkoon's servers, which means there are absolutely no file size limits, no mandatory accounts, and complete privacy. Because this method costs Perkoon essentially nothing to run, it's completely free for you to use, forever. It's file sharing in its purest, most efficient form.
Honest Encrypted Cloud Storage
For when your friend or colleague is offline, Perkoon offers a paid cloud storage option. This feature is built on transparency: your files are encrypted on their servers, and you pay a fair price that directly covers the cost of providing that storage and bandwidth. There's no hidden agenda or data monetization. It's a straightforward solution for asynchronous file sharing without compromising on security.
Native AI & Automation Ready
Perkoon is built for the future. Instead of forcing AI assistants to awkwardly scrape a website, Perkoon provides a direct way for them to interact with the service through window.__perkoon. This means your AI agents can upload, download, and manage transfers programmatically and efficiently, opening up powerful possibilities for workflow automation without the typical technical headaches.
Simple CLI and Browser Tools
Accessibility is key. Alongside its user-friendly web interface, Perkoon offers a simple Command Line Interface (CLI) tool. This allows tech-savvy users, developers, or automated scripts to integrate file transfers directly into their workflows, from servers to local machines, making Perkoon a versatile tool for both casual and power users.
The Ultimate Piano
Play Piano Online Instantly
Jump right into playing without any downloads or installations. Simply open your web browser and start making music. You can use your mouse to click keys, your computer keyboard as a piano, or connect a real MIDI keyboard for a more traditional playing experience. The tool features high-quality, realistic piano samples that make every note sound beautiful and authentic, encouraging you to play and explore.
MIDI Player with Falling Notes Visualization
Learn songs faster by watching them come to life. Upload any MIDI file, and you'll see the notes light up on the keyboard as they play, just like in popular learning apps. You have full control: slow down the tempo to a comfortable speed, loop tricky sections to practice them repeatedly, or even step through the song note-by-note to master every detail without feeling rushed.
Real-Time Chord Detection & Explorer
Unlock the secrets of harmony as you play. This smart feature listens to your playing and instantly displays the name of the chord you are creating on the screen. It’s a fantastic, hands-on way to learn how chords are built and how they relate to each other. The accompanying Chord Explorer lets you dive deeper into music theory, showing you the notes that make up any chord you select.
Integrated Audio & YouTube Player
Practice along with your favorite music seamlessly. You can upload your own MP3 files or paste a YouTube video link directly into the tool. Slow down the playback speed without changing the pitch to learn complex solos note-for-note. Use the A-B loop function to isolate and repeat a challenging four-bar phrase over and over until you nail it, turning any song into an interactive lesson.
Use Cases
Perkoon
Sending Large Project Files to a Client
Need to send a massive video edit, design portfolio, or dataset that's over 50GB? With Perkoon's P2P transfer, you can send it instantly and for free. Just generate a link, share it with your client while you're both online, and the file transfers directly to them without any size restrictions or upload waits to a third-party server.
Sharing Personal Photos and Videos Privately
Tired of services compressing your memories or snooping on your content? Use Perkoon's P2P transfer to share original-quality photos and videos from your holiday or family event directly with loved ones. Since the files go browser-to-browser, they remain completely private between you and the recipient.
Automating Backup Scripts with CLI
As a developer, you can use Perkoon's CLI tool to automate file backups. Write a simple script that uses the CLI to upload crucial logs, database dumps, or project archives directly to your Perkoon cloud storage at regular intervals, creating an efficient, automated off-site backup solution.
Enabling AI Agents to Handle File Tasks
Imagine an AI research assistant that can automatically fetch datasets or save its generated reports. By leveraging Perkoon's native AI integration, you can configure your agent to use the service directly. It can upload collected data or download necessary files without you manually intervening, streamlining complex research or content creation workflows.
The Ultimate Piano
The Complete Beginner's Starting Point
If you've never touched a piano before, this is your ideal launchpad. Start by learning the names of the notes with the helpful key labels. Use the "Kids Mode" with fun animal icons to make it engaging, or follow along with simple YouTube tutorials using the built-in player. The instant feedback from the tool helps you build confidence from your very first note.
The Song Learner's Practice Partner
Do you want to learn a specific song? Load the MIDI file or a YouTube tutorial of the piece. Use the falling notes to see exactly which keys to press and slow down difficult sections. Record yourself playing along with the MIDI recorder, then listen back to track your progress and identify areas that need a little more work.
The Music Theory Student's Visual Aid
Struggling to understand scales or chord progressions? Select a scale like the "Blues Scale in Ab" and see it highlighted across the keyboard while hearing it played. Use the Scale Trainer to get feedback on your accuracy and timing. Play random chords and use the real-time chord detection to learn their names, solidifying the connection between sound and theory.
The Busy Musician's On-the-Go Studio
Life is busy, but your practice doesn't have to stop. Since it works on tablets and smartphones, you can practice during your lunch break or while traveling.

Frequently Asked Questions
Perkoon FAQ
Is the P2P transfer really free forever?
Yes, absolutely. Perkoon's peer-to-peer transfer is free forever because of how it works. The files are sent directly from your device to the recipient's device without ever being stored on or passing through Perkoon's servers. This means it costs Perkoon virtually nothing in bandwidth or storage, so they can offer it completely free, with no hidden limits or future fees.
What happens if the other person is offline?
If the recipient is not online to receive the direct P2P transfer, Perkoon offers a solution: encrypted cloud storage. This is a paid feature. You can upload the file to Perkoon's secure servers, and they will hold it for your recipient. When the recipient comes online, they can download it from this temporary cloud storage. You only pay for this cloud storage feature.
Can Perkoon see what I'm sending with P2P?
No, they cannot. During a P2P transfer, your file is broken into encrypted chunks and streamed directly between your browser and the recipient's browser using a secure WebRTC connection. Perkoon's servers only help set up this direct connection (a process called signaling) but never handle the actual file data. They literally have no way to see your files.
Can I use Perkoon with any web browser?
For the best, unlimited experience, Perkoon recommends using Chromium-based browsers like Chrome, Edge, or Brave. These browsers fully support the required technologies. Firefox and Safari can be used, but they have inherent browser restrictions that may limit performance or file size for P2P transfers. It's always best to check the official site for the most current browser compatibility information.
The Ultimate Piano FAQ
Do I need to install anything to use Ultimate Piano?
No, you do not need to install any software! The Ultimate Piano is entirely browser-based. This means you can access it directly from your web browser (like Chrome, Safari, or Firefox) on your computer, tablet, or smartphone. Just visit the website, and you can start playing and practicing immediately.
Can I connect my MIDI keyboard?
Absolutely! Connecting a MIDI keyboard is highly recommended for the best experience. Simply plug your keyboard into your computer (usually via USB), and the Ultimate Piano will automatically detect it. You can then play with a realistic, weighted key feel. The tool also supports connecting a sustain pedal for more expressive playing.
What chords and scales can I learn?
The Ultimate Piano includes a comprehensive library for learning. You can explore and practice 14 different scale types, from major and minor to more advanced modes like Dorian and Mixolydian. The chord explorer covers a vast range, from basic triads (like C Major) to complex seventh and extended chords (like Gmaj7), giving you a deep understanding of harmony.
Can I practice along with my own songs?
Yes, you can! The built-in Audio Player allows you to upload your own MP3, WAV, or other audio files to play along with. Even better, the YouTube Player lets you paste a link to any YouTube video—like a song, tutorial, or performance—and practice directly alongside it. You can slow it down, set loops, and save markers for easy practice.
