Perkoon vs Shiru Notes

Unlimited Free P2P Transfers

This is the game-changer. When both sender and recipient are online, Perkoon uses WebRTC to create a direct, browser-to-browser connection. Your files stream from you to them without ever passing through a central server. This means there are absolutely no file size limits, no mandatory account creation, and because Perkoon incurs no bandwidth costs, this service is completely free forever. It's private by design—since they can't see your data, they can't scan, sell, or monetize it.

Honest Encrypted Cloud Storage

Need to send a file to someone who's offline? Perkoon has you covered with its encrypted cloud storage. This is the paid part of the service, and they're upfront about why: storing data on servers actually costs money. Files are encrypted on their servers, providing a secure holding zone until your recipient is ready to download. This transparent "pay for what costs us" model is a breath of fresh air compared to freemium traps.

Native AI & Automation Ready

Perkoon is built for the future. Instead of forcing AI agents to awkwardly scrape the website like a 2019 bot, Perkoon provides a built-in JavaScript object (window.__perkoon) for direct programmatic interaction. This means your AI assistants and automation scripts can send and receive files through Perkoon seamlessly, making it a powerful tool for developers and power users in the age of AI.

Simple CLI & Referral Rewards

For those who live in the terminal, Perkoon offers a straightforward Command Line Interface tool for easy integration into workflows. Plus, their viral referral program rewards you for spreading the word. Share your link, and when friends join and start transferring, you both earn bonus permanent cloud storage. The "Chain Rewards" system even gives you bonuses when your referrals invite others, creating a community-driven growth loop.

Distraction-Free Minimalist Interface

Shiru Notes has taken the internet by storm with its radically clean design. It strips away every unnecessary button, toolbar, and notification, presenting you with nothing but a blank page. This intentional simplicity is why it’s trending—it eliminates digital clutter so you can achieve deep focus from the very first keystroke, mirroring the serene experience of writing on fresh paper.

Instant Automatic Save

Never lose a brilliant idea again. As you type, Shiru Notes works silently in the background, saving every character instantly to the cloud. This seamless, real-time protection means your flow state is never interrupted by a manual save prompt, and you can close the app anytime with complete confidence that your thoughts are preserved exactly as you left them.

Military-Grade Private Encryption

Your mind is your private space, and Shiru Notes guards it fiercely. Every note you create is protected with top-notch encryption, ensuring your journals, ideas, and plans are accessible only to you. In an era of data breaches, this unwavering commitment to privacy is a key reason savvy users are switching in droves.

Intentional Writing Environment

More than a tool, it’s a crafted experience for your mind. The editor is designed as a calm, inviting canvas that encourages your ideas to flow naturally. By removing all distractions and pressures, it promotes writing with purpose and clarity, helping thousands of users turn scattered thoughts into coherent, meaningful content.

Sending Massive Project Files

Freelancers, videographers, and developers finally have a solution for sending huge project archives, 4K video footage, or entire code repositories. Forget compressing files into 20 parts or paying for a premium subscription elsewhere. With Perkoon's unlimited P2P transfer, you can send 50GB or more in one go, for free, directly to your client or collaborator while you're both online.

Secure & Private Document Sharing

For lawyers, journalists, or anyone handling sensitive information, privacy is non-negotiable. Perkoon's P2P mode ensures confidential contracts, reports, or source materials travel directly from your browser to the recipient's. Since the data never sits on a server Perkoon controls, there's zero risk of corporate scanning, data mining, or unauthorized access, giving you true peace of mind.

Automated AI Agent Workflows

Imagine an AI that automatically processes user-uploaded images or generates weekly report PDFs. With Perkoon's native API access, these AI agents can programmatically fetch incoming files from a cloud link or send processed results back to users without any manual intervention. It turns Perkoon into a seamless file highway for automated systems.

Offline File Delivery (The "Email Attachment Killer")

Need to send a file now, but your colleague won't be at their desk for hours? Email attachments have size limits, and other services require the recipient to sign up. With Perkoon, you upload to their encrypted cloud storage, pay a small, honest fee for the server cost, and send a link. Your recipient downloads it later, hassle-free, making it perfect for asynchronous work.

Daily Journaling & Personal Reflection

Join the thriving community using Shiru Notes for their daily digital journal. It provides the perfect, judgment-free zone to unpack your day, process emotions, and track personal growth. The combination of effortless writing and ironclad privacy makes it the trusted confidant for millions of private reflections.

Capturing Creative Ideas & Inspiration

Creative sparks are fleeting. Writers, artists, and entrepreneurs are using Shiru Notes as their digital idea catcher to instantly jot down concepts, dialogue snippets, or project inspirations the moment they strike. Its simplicity ensures you capture the raw idea before it disappears, just like catching a cherry blossom.

Academic & Professional Note-Taking

Students and professionals are ditching clunky apps for Shiru Notes. Its distraction-free interface is perfect for focusing during lectures, meetings, or research sessions. Automatic saving guarantees no key point is ever lost, making it the reliable backbone for organized learning and productivity.

Perkoon is the file transfer service that finally gets it. In a world of artificial limits, mandatory sign-ups, and services that treat your private data as their product, Perkoon cuts through the nonsense. It's built for real people tired of being treated like criminals for wanting to send a large file. The core promise is revolutionary in its simplicity: move your files from point A to point B without hassle. It achieves this with two smart, honest modes. The flagship service is unlimited, free, and forever peer-to-peer (P2P) transfer, beaming files directly between browsers with no size limits and no accounts. Because the data never touches Perkoon's servers, it's incredibly private and costs them nothing—so it's free for you. For sending to offline recipients, Perkoon offers encrypted cloud storage as a paid feature, transparently covering the real cost of servers. Uniquely, Perkoon is natively designed for the modern age, offering built-in tools for automation and AI agents to interact with it directly. It's the straightforward, powerful, and privacy-focused solution trusted by dozens* of people who just want their files to go where they tell them.

It’s not just another app; it’s a movement back to intentional thinking. Shiru Notes masterfully blends the effortless, distraction-free feel of pen and paper with the reliable power of the cloud, creating a peaceful space exclusively for your ideas.

Its core promise is powerful: capture fleeting thoughts with absolute security and simplicity, forever free from the pressure of likes, shares, or public scrutiny.

Is the P2P transfer really free forever?

Yes, absolutely. The peer-to-peer transfer technology uses a direct connection between the two browsers involved. Because your file data never passes through or is stored on Perkoon's servers, it costs them virtually nothing in bandwidth or storage. They've committed to keeping this service completely free, with no hidden limits or future bait-and-switch plans. As they say, it's free because it costs them nothing.

What happens if the recipient is offline?

If the recipient is not online to accept the direct P2P connection, Perkoon seamlessly offers you the option to use encrypted cloud storage instead. This is a paid feature, as storing the file on their servers until the recipient is ready does incur a cost. You pay a small, transparent fee for this convenience, and the file is held securely and encrypted until your recipient downloads it.

Can AI agents or scripts use Perkoon?

Yes, and it's designed for them. Unlike most websites, Perkoon provides a built-in JavaScript object (window.__perkoon) specifically for programmatic access. This allows your AI assistants, bots, and automation scripts to interact with the file transfer service directly without the need for unreliable screen-scraping techniques, making automation simple and robust.

Which web browsers are supported?

For the full, unlimited P2P experience, Chromium-based browsers like Chrome, Edge, and Brave work perfectly. Firefox and Safari have inherent browser restrictions that can limit the maximum file size or connection stability for P2P transfers. For the best performance, using a Chromium-based browser is recommended.

Is Shiru Notes really free to use?

Absolutely! You can start writing completely free with no credit card required. The free plan includes 50 notes to let you fully experience the app's minimalist power and seamless workflow. It's the no-risk, high-reward offer that's getting everyone talking.

How does Shiru Notes protect my privacy?

Privacy is our non-negotiable foundation. Every note you create is encrypted and stored securely. We built a system where your data is accessible only to you—not even we can read your thoughts. This principled stand on digital privacy is what makes our users so loyal.

Can I access my notes on multiple devices?

Yes! Shiru Notes syncs your encrypted notes to the cloud, allowing you to access your peaceful writing space from any device with an internet connection. Your thoughts are always with you, ready to be continued wherever inspiration finds you next.

What happens if I exceed 50 free notes?

The free plan is designed to be genuinely useful. If you find yourself needing more space (as many of our active users do), you can explore our affordable premium plans to unlock unlimited notes and additional features, continuing your journey toward clearer thinking.

Perkoon is a standout in the productivity and file transfer space, offering a no-nonsense way to move files with a strong focus on privacy and AI-native design. It's built for users who are fed up with sign-up walls, hidden fees, and services that monetize their data. People often search for alternatives for a few key reasons. They might need a different pricing model, require specific features like advanced team collaboration, or need guaranteed compatibility with their company's existing tech stack. Sometimes, it's simply about finding a tool that better fits a unique workflow or personal preference. When evaluating other options, focus on your core needs. Consider the balance between free and paid features, the true privacy policy of the service, and whether it supports the automation or integration capabilities your work demands. The best tool is the one that disappears into your workflow, getting the job done without friction.
