Feature Comparison
Perkoon
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.
SureThing.io
Proactive Autonomous Operation
SureThing doesn't wait for you to tell it what to do. It actively monitors your connected workspaces—like your email inbox and calendar—and takes intelligent action on your behalf. It can draft and send email replies, schedule meetings, set reminders, and update project statuses autonomously, freeing you from constant manual oversight and context-switching.
Persistent, Context-Aware Memory
This is the core magic. Unlike AI that resets with every chat, SureThing has a long-term memory that builds over time. It remembers your communication style, your priorities, your recurring tasks, and the nuances of your ongoing projects. The longer you work together, the smarter and more personalized its assistance becomes, requiring less explanation from you.
Enterprise-Grade Security & Reliability
SureThing is built for real-world, sensitive work. It is SOC 2 Type II certified and Google CASA Tier 2 compliant, meeting rigorous standards for data security, privacy, and availability. This isn't a fragile demo; it's a robust platform designed for professionals and businesses that need an agent they can trust with their actual data and workflows.
Cross-App Action & Integration
SureThing works as a central orchestrator across your essential applications. It can take actions in your email client, calendar, project management tools, and more, creating a seamless workflow. This allows it to manage complex, multi-step tasks that involve several apps, acting as a unified assistant for your entire tech stack.
Use Cases
Perkoon
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.

Frequently Asked Questions
Perkoon FAQ
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.
SureThing.io FAQ
How is SureThing different from ChatGPT or other AI chatbots?
ChatGPT is a reactive tool—you ask, it answers, and the context resets. SureThing is a proactive, autonomous agent. It works continuously in the background, takes initiative based on your goals, and possesses a permanent memory of your work and preferences. It's designed for ongoing action and delegation, not just conversation.
What does "Google CASA Tier 2 Compliant" mean?
Google's CASA (Cloud Application Security Assessment) framework is a rigorous security standard. Tier 2 compliance signifies that SureThing has undergone and passed an independent, in-depth assessment of its security posture, data protection practices, and infrastructure. It's a strong validation of our enterprise-ready security for Google Workspace users.
Can I trust SureThing with sensitive emails and data?
Absolutely. Security is our foundation. Beyond Google CASA Tier 2, we are SOC 2 Type II certified, which is an industry-standard audit for service organizations covering security, availability, processing integrity, confidentiality, and privacy. Your data is encrypted and handled with the highest standards of trust and compliance.
How does SureThing "learn my voice" for communication?
SureThing's persistent memory analyzes your past written communications—your tone, phrasing, formality level, and common expressions. Over time, it builds a nuanced model of your unique style. When drafting emails or messages on your behalf, it applies this model to generate text that sounds authentically like you, maintaining your personal or professional brand.
