Perkoon vs securememo.app

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.

Client-Side End-to-End Encryption

This is the foundational security feature. All encryption and decryption processes happen exclusively within your web browser on your local device. Your sensitive note is transformed into unreadable ciphertext using a strong password before it is ever transmitted to securememo.app's servers. This guarantees that the service provider, internet intermediaries, or potential attackers who breach the server can never access the original content of your memo, as they never possess the decryption key.

Self-Destructing Notes with Unique Links

Each memo you create generates a unique, one-time-use URL. Once this link is accessed and the note is decrypted with the correct password, the note is permanently deleted from the server. This ephemeral nature ensures that sensitive information does not persist indefinitely in a digital vault, drastically reducing the risk of exposure from future data breaches or unauthorized access. It enforces a "read-once" principle for maximum confidentiality.

Zero-Knowledge Password Generation

For maximum security, securememo.app generates a strong, random decryption password entirely on your device. This password is never sent to or stored by their servers. You must share this password with your intended recipient through a separate, secure channel (like a secure messaging app or in person). This separation of the encrypted data and its key is a critical security practice, ensuring that even if the memo link were somehow compromised, the content remains protected without the password.

No-Account-Anonymity & Global Access

You can use securememo.app immediately without creating an account, providing an email address, or submitting any personal information. This design prioritizes user anonymity and simplifies the process. Combined with availability in over 20 languages, the service is accessible to a global audience, removing technical and linguistic barriers to secure communication for users everywhere, regardless of their technical expertise.

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.

Sharing Login Credentials Securely

Instead of sending a username and password via email or Slack—where it remains in logs and inboxes—you can create an encrypted memo. Share the link with your colleague or client and the password via a different method (e.g., a quick phone call or Signal message). They access the credentials once, and the note self-destructs, leaving no permanent, vulnerable record of your sensitive login information on any server.

Sending Confidential Documents or Messages

Professionals such as lawyers, accountants, or HR managers can use securememo.app to send confidential contract details, financial reports, or sensitive personal feedback. The client-side encryption ensures the content is protected in transit and at rest, while the self-destruct feature guarantees the information isn't stored beyond its intended single use, maintaining client confidentiality and compliance with data protection principles.

Secure Communication for Journalists and Sources

Journalists can provide a securememo.app link to a source as a dead-drop for sensitive tips, documents, or statements. The source can encrypt their information without needing an account, preserving their anonymity. The zero-knowledge architecture means the journalist's platform cannot be compelled to hand over data it does not possess, protecting the source's identity and the integrity of the information.

One-Time Private Notes for Personal Use

Individuals can use the service for their own personal security needs. This includes creating a memo with emergency recovery codes for online accounts, a copy of a will's location, or private financial PINs, and saving the link and password in separate, secure places. It acts as a secure, ephemeral digital safe-deposit box that only you can open, without relying on a potentially vulnerable cloud note-taking service.

Perkoon is a file transfer service designed to solve the core problem of moving files from one point to another without the typical friction, privacy invasions, and hidden costs. It is built for individuals, freelancers, and teams who are tired of artificial file size limits, mandatory account creation, and services that monetize user data. Perkoon's main value proposition is its refreshingly honest and technically elegant two-mode system. Its flagship offering is a completely free, unlimited peer-to-peer (P2P) transfer service that works directly between browsers when both parties are online, ensuring privacy and eliminating operational costs. For situations where the recipient is offline, Perkoon offers a straightforward paid cloud storage option, transparently priced to cover server costs. Uniquely, Perkoon is natively built for automation, featuring tools that allow AI agents and scripts to interact with the service directly, making it a future-proof solution for both people and the machines that assist them.

Securememo.app is a privacy-first, web-based tool designed for creating and sharing sensitive information with uncompromising security. It solves the common problem of needing to send confidential data—like passwords, financial details, or private messages—through insecure channels like email or standard messaging apps, where they can be intercepted, read by service providers, or linger indefinitely. The core value proposition is absolute data sovereignty for the user. By employing client-side, end-to-end encryption, securememo.app ensures that your sensitive content is encrypted on your own device before it ever touches their servers. This means the service itself has "zero knowledge" of your data; they cannot read, access, or share your memos. The platform is built for anyone who values digital privacy, including professionals sharing credentials, journalists communicating with sources, individuals sending personal data, or anyone wanting a secure, ephemeral way to pass information. With no account registration required and support for over 20 languages, it prioritizes both anonymity and global accessibility, making top-tier encryption practical and easy to use for everyone directly from their web browser.

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.

How does securememo.app ensure my notes are secure?

Security is ensured through client-side, end-to-end encryption. Your note is encrypted in your web browser using a strong password before it is sent to our servers. We never receive or store the encryption password. Therefore, we have zero knowledge of your note's content. The encrypted data is stored temporarily and is permanently deleted immediately after the intended recipient decrypts and views it using the unique link and password.

What happens if someone guesses the password or the link is intercepted?

The security of your memo relies on the strength of the randomly generated password and the secrecy of the link. We generate very strong, random passwords to make guessing practically impossible. However, if both the link and the password are intercepted by an unauthorized party, they could access the memo. This is why we strongly recommend sharing the link and password through separate communication channels to minimize this risk.

Do I need to install any software or create an account?

No. Securememo.app is a web application that runs entirely in your browser. There is no software to download or install. More importantly, you do not need to create an account or provide any personal information like an email address to use the service. This protects your anonymity and makes the tool instantly accessible.

In how many languages is securememo.app available?

Securememo.app is designed for a global user base and is currently available in over 20 languages. This broad language support ensures that users from different regions can use the service comfortably in their native language, making secure communication accessible to a wider audience without language being a barrier to privacy.
