Every conversation is stored in one searchable place, regardless of the model used. This feature ensures that users can easily revisit past interactions, making it simple to track conversations across various AI models without losing context.

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.
Use Cases
ChatXOS
Efficient Coding Assistance
Developers can use ChatXOS to debug code with one model while seeking explanations or alternative solutions from another. This flexibility allows for a more comprehensive approach to coding challenges.
Enhanced Writing Support
Writers and students can draft content using Claude for its creative prowess and then fact-check or enrich their work with research from Gemini. This multi-model approach ensures high-quality output and accurate information.
Accelerated Decision-Making
Founders and business operators can leverage the strengths of different AI models to make informed decisions quickly. By accessing the best model for each specific task, they can streamline their operations and improve productivity.
Comprehensive Research Capability
Researchers can utilize ChatXOS to gather information from various AI models. Whether conducting literature reviews or summarizing complex topics, the app facilitates a more thorough and nuanced understanding of the subject matter.
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.

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.
