Feature Comparison

Perkoon

Truly Free P2P Transfers

This is the heart of Perkoon. When both sender and receiver are online, files travel directly between their web browsers using WebRTC technology. There is no intermediary server, which means there are absolutely no file size caps, no forced account creation, and your data is never stored by Perkoon. It's fast, private, and free because the architecture makes it cost-effective to offer.

Encrypted Cloud Storage for Offline Recipients

Life doesn't always sync up. When you need to send a file to someone who isn't currently online, Perkoon's cloud storage steps in. Your file is encrypted and securely held on a server until your recipient is ready to download it. This is the part of the service that has real infrastructure costs, which is why it operates on a paid model, keeping the business transparent and sustainable.

Native AI & Automation Accessibility

Perkoon is built for the future. It features a machine-readable state, stable DOM selectors, and a dedicated automation API (window.__perkoon). This allows AI assistants, bots, and automated workflows to send and receive files programmatically without the inefficiency and fragility of simulating human clicks. It’s file transfer designed for both people and their digital agents.

Command Line Interface (CLI) Tool

For developers and terminal enthusiasts, Perkoon offers a full-featured CLI accessible via npx perkoon. You can send and receive files directly from your command line, enabling seamless browser-to-CLI and CLI-to-CLI transfers. It brings the same simplicity and power of the web service to your workflow, proving that terminals deserve nice things, too.

SureThing.io

Proactive Autonomous Operation

Unlike passive tools that wait for commands, SureThing takes initiative. It constantly scans your connected work environments—like your email inbox—identifies what needs attention, and acts on your behalf. This means it can flag urgent messages, draft initial responses, and manage routine tasks without you having to prompt it every single time, freeing you to concentrate on strategic thinking.

Persistent, Adaptive Memory

This is SureThing's core superpower. It builds a comprehensive understanding of you over time, remembering your communication style, your priorities for different projects, and your preferences for scheduling. The longer you work together, the less context you need to provide. It won't forget a detail you mentioned last week, ensuring consistency and personalized service in every action it takes.

Enterprise-Grade Security & Reliability

SureThing is built for users who need to trust an AI with real, sensitive work. With SOC 2 certification and Google CASA Tier 2 compliance, it meets rigorous standards for data security, privacy, and system availability. This foundation of trust means you can confidently connect it to your critical work apps, knowing it's designed for dependable, day-in, day-out performance.

Cross-App Action & Integration

SureThing doesn't just observe—it acts. It can move information and execute tasks across the applications you use, such as updating your project management tool when an email confirms a deliverable or scheduling a follow-up meeting based on a conversation thread. This creates a seamless, automated workflow that bridges gaps between your favorite tools.

Use Cases

Perkoon

Sending Large Project Files to a Client

Freelancers and creatives often need to send massive video edits, design portfolios, or code repositories that exceed the limits of email or other free services. With Perkoon's P2P transfer, you can send hundreds of gigabytes directly to your client's browser in one go, for free, with no compression or wait times, ensuring they get the full-quality work.

Automated Backup Scripts and AI Workflows

A developer has a script that generates nightly reports or an AI agent that creates weekly content batches. Using Perkoon's API or CLI, these automated processes can instantly send the generated files to a designated recipient or cloud folder without any manual intervention, seamlessly integrating file transfer into automated pipelines.

Sharing Personal Media Collections

Imagine wanting to share all your vacation photos and videos from a recent trip with family—a collection easily reaching 50GB. Instead of splitting into dozens of links or paying for a one-time transfer, you can create a single Perkoon P2P link. As long as your family is online, they can download the entire collection directly from you, quickly and privately.

Ad-Hoc Collaboration Between Teams

Two remote team members need to exchange a large dataset or a prototype asset immediately during a call. Instead of uploading to a slow cloud drive, one can start a Perkoon P2P transfer and share the link in the chat. The other person clicks and the file downloads in real-time, facilitating instant, frictionless collaboration without leaving the browser.

SureThing.io

The Overwhelmed Solo Founder

For a founder running a business alone, SureThing acts as a force multiplier. It can manage inbound customer inquiries, draft responses, track outreach campaigns, and help coordinate a product launch—all while the founder focuses on product development and high-level strategy. It effectively provides the support of an extra team member.

The Executive with a Packed Schedule

Busy executives can offload the cognitive load of calendar management and communication triage. SureThing can prioritize emails, draft succinct summaries of long threads, schedule meetings based on preferences, and ensure nothing falls through the cracks, allowing the executive to stay focused on leadership and decision-making.

The Project Manager Juggling Multiple Threads

SureThing helps project managers stay on top of dependencies and communications. It can monitor project-specific email channels, update task statuses in tools like Asana or Jira based on updates, send gentle reminder follow-ups to contributors, and compile progress reports, keeping the entire project moving forward smoothly.

The Professional Protecting Deep Work Time

For anyone who needs uninterrupted blocks of time, SureThing serves as a protective shield. It can handle routine communications, filter out non-urgent notifications, and only escalate truly important items. This allows the user to enter a state of deep focus without the constant fear of missing something critical.

Overview

About Perkoon

Perkoon is a refreshingly honest file transfer service that cuts through the noise and gets back to basics: moving your files from point A to point B without hassle. It's built for anyone tired of artificial limits, mandatory sign-ups, and services that treat your data as a product. At its core, Perkoon offers two smart ways to send files. First, its flagship free service uses peer-to-peer (P2P) technology to beam files directly between browsers when both people are online. This means no size limits, no accounts, and because the data never passes through a central server, it's private and costs Perkoon nothing to run—so it's free for you, forever. For when the recipient is offline, Perkoon provides encrypted cloud storage, a paid feature that honestly covers the cost of running servers. What truly sets Perkoon apart is its native design for the age of AI, offering built-in tools for automation and AI agents to interact with the service directly, no screen-scraping required. With a simple CLI tool also available, Perkoon is the straightforward, powerful, and privacy-focused file transfer solution for real people and the machines that help them.

Frequently Asked Questions

Perkoon FAQ

Is peer-to-peer (P2P) transfer really free forever?

Yes, absolutely. Perkoon's P2P transfer is free and unlimited because of how it works: files stream directly from one browser to another without ever touching Perkoon's servers. This means there are no storage or bandwidth costs for the company to cover for this specific service, so they can genuinely offer it for free indefinitely, no strings attached.

What happens if the person I'm sending to is offline?

If your recipient is not online to accept the direct P2P connection, Perkoon offers a seamless fallback to encrypted cloud storage. You can choose this option to upload your file to Perkoon's servers, where it is encrypted and held until your recipient comes online to download it. This cloud storage service is a paid feature, as it involves real infrastructure costs.

How does Perkoon protect my privacy?

Privacy is a core principle. In P2P mode, your files never pass through Perkoon's servers; they take a direct path between you and the recipient, so Perkoon cannot see your data. For cloud transfers, files are encrypted on their servers. Perkoon has a strict no-scanning, no-selling data policy, ensuring your files stay yours.

Can I use Perkoon from the command line?

Definitely! Perkoon provides an official Node.js CLI tool. You can install and run it directly with npx perkoon send [file] or npx perkoon receive. This allows you to initiate transfers from your terminal to a web browser, or even between two terminals, making it perfect for scripting and server environments.

SureThing.io FAQ

How is SureThing different from a standard AI chatbot?

Standard chatbots are reactive—they only respond when you ask a question. SureThing is proactive and autonomous. It takes initiative based on its understanding of your work and goals. Furthermore, its persistent memory means it learns and remembers your context permanently, unlike chatbots that start fresh with each conversation.

What does "Google CASA Tier 2 Compliant" mean?

Google's Cloud Application Security Assessment (CASA) framework evaluates the security of applications that integrate with Google Workspace. Tier 2 compliance is a rigorous level that indicates SureThing has undergone a thorough independent security review, giving you confidence that it handles your Google-connected data with a high standard of protection.

Can I control what SureThing does on my behalf?

Absolutely. You maintain full oversight. SureThing is designed to suggest actions and draft communications for your review before sending. You can approve, edit, or reject anything. Over time, as it learns your preferences, it may automate more routine tasks, but you always have the final say and can adjust its permissions.

How does SureThing learn my "voice" for communication?

SureThing analyzes your past written communications—emails, messages, etc.—to understand your tone, formality, common phrases, and style. When it drafts a reply or message, it mimics these patterns. You can also provide direct feedback ("make this more casual" or "sound more enthusiastic"), which it remembers and applies to future drafts.
