Perkoon vs Session Stacker

Unlimited Free P2P Transfers

Perkoon's core feature is its unlimited, free peer-to-peer file transfer service. Utilizing WebRTC and similar technologies, it establishes a direct, encrypted connection between two web browsers. This process eliminates intermediary servers, meaning there are no file size limits, no mandatory sign-ups, and absolute privacy as Perkoon cannot access the data stream. This model is sustainably free because it incurs negligible infrastructure costs for the provider, a principle Perkoon openly communicates.

Encrypted Cloud Storage for Offline Recipients

For situations where the recipient is not immediately online, Perkoon provides encrypted cloud storage. This is a paid feature, with pricing structured transparently to cover the tangible costs of server maintenance, storage, and bandwidth. Files are encrypted on Perkoon's servers, providing a secure holding mechanism. This honest bifurcation between free P2P and paid cloud storage defines Perkoon's ethical and sustainable business approach.

Native AI and Automation Integration

Perkoon is architecturally designed for the age of automation. It exposes a dedicated JavaScript object (window.__perkoon) and provides a Command Line Interface (CLI) tool, allowing AI agents and scripts to interact with the service programmatically. This eliminates the need for unreliable DOM scraping, enabling seamless integration into automated workflows, AI-assisted tasks, and developer pipelines without human intervention.

Transparent Referral and Rewards Program

To incentivize growth, Perkoon operates a multi-tiered referral program. Users share a unique link; when a new user signs up via that link and completes 1GB of P2P transfers within seven days, both parties receive bonus cloud storage. The program extends to "chain rewards," where users also earn bonuses from the subsequent referrals made by people they invited, creating a network effect that rewards community building.

AI-Powered Task Review

The AI-powered task review feature analyzes your completed tasks and suggests the most effective next steps based on your previous work. This eliminates guesswork and provides users with tailored recommendations that enhance productivity.

Streak Tracking

Session Stacker includes a streak tracking function that helps users build consistency over time. By visualizing their progress, users are motivated to maintain their work habits, fostering a sense of accomplishment with each completed session.

Session History

The session history feature allows users to view their past work sessions in detail. This not only helps in understanding what has been accomplished but also aids in identifying patterns and areas for improvement in their workflow.

Detailed Statistics

Users benefit from comprehensive statistical insights that illustrate their progress over time. These insights include metrics such as the total number of sessions completed and the weekly targets achieved, providing visible proof of productivity.

Sending Large Media Files Creatives

Video editors, photographers, and graphic designers frequently need to send multi-gigabyte project files, raw footage, or high-resolution assets to clients or collaborators. Perkoon's unlimited P2P transfer allows them to send these files instantly without compressing quality, waiting for uploads to third-party servers, or hitting paywalls, all while maintaining complete data privacy.

Secure Document Exchange for Professionals

Lawyers, journalists, healthcare professionals, and consultants handling sensitive documents require confidential file exchange. Perkoon's direct P2P transfer ensures documents never reside on a third-party server where they could be scanned or monetized. For asynchronous sharing, the encrypted cloud storage provides a secure, auditable option without corporate data mining.

Automated Backup and Sync Scripts

Developers and system administrators can leverage Perkoon's CLI and API access to build automated scripts. This enables use cases like scheduled backups of server logs or code repositories directly to a Perkoon cloud storage destination, or triggering file transfers as part of a CI/CD pipeline, all executed by machines without manual browser interaction.

AI Agent File Management

An AI personal assistant or agent can use Perkoon's native window.__perkoon interface to manage files on behalf of a user. For example, an agent could automatically retrieve a report generated by another tool and send it via P2P to a colleague's browser, or save a generated image to the user's Perkoon cloud storage, all through structured API calls.

Evening Side Hustlers

For professionals who work full-time yet wish to pursue side projects in the evenings, Session Stacker offers a streamlined method to quickly jump back into work without losing precious time to memory recall.

Creative Writers

Writers often face challenges when returning to their drafts after a break. With Session Stacker, they can set specific next steps to ensure a smooth transition back into their writing, maintaining narrative flow and creativity.

App Developers

Developers juggling multiple projects can utilize Session Stacker to keep track of where they left off with each application, allowing them to efficiently manage coding sessions and feature implementations without losing track of their priorities.

Freelancers

Freelancers who manage various client projects can benefit from Session Stacker’s clear task-setting feature. By defining their next steps before concluding a session, they can ensure they are always ready to resume work effectively without additional planning.

Perkoon is a privacy-first file transfer service designed to eliminate the friction and data exploitation common in modern digital tools. It operates on a transparent, cost-reflective model that fundamentally separates peer-to-peer (P2P) transfers from cloud-based storage. Its flagship offering is an unlimited, free P2P service that facilitates direct browser-to-browser file transfers when both sender and recipient are online. This method imposes no file size limits, requires no user accounts, and ensures privacy as data never transits Perkoon's servers. For offline transfers, Perkoon offers encrypted cloud storage as a paid feature, honestly pricing it to cover server infrastructure costs. The service is engineered for both human users and AI agents, featuring native API accessibility to prevent the need for inefficient screen-scraping. Perkoon's value proposition is clear: a straightforward, powerful tool that respects user privacy, offers genuine utility without artificial restrictions, and aligns its business model directly with the technical realities of data transfer.

Session Stacker is an innovative productivity tool designed specifically for individuals managing side hustles alongside full-time jobs. It addresses a critical pain point for many side hustlers: the challenge of remembering where they left off after a work session. Instead of allowing time to slip away while recalling past tasks, Session Stacker encourages users to establish a simple habit: before ending a work session, they define their next actionable step. This straightforward practice eliminates the typical ramp-up time lost to indecision, enabling users to dive straight into their work when they return. The tool is equipped with features like AI-powered task review, streak tracking, and detailed progress statistics, making it an essential companion for anyone with limited evening energy who is committed to building projects. By focusing on clear next steps instead of overwhelming project management systems, Session Stacker empowers users to maintain momentum and consistently progress towards their goals.

How can P2P transfers be completely free?

Perkoon's P2P technology establishes a direct connection between users' browsers using WebRTC. The file data streams directly from the sender's device to the recipient's without passing through or being stored on Perkoon's infrastructure. This direct transfer model incurs virtually no bandwidth or storage cost for Perkoon, allowing the service to be offered free indefinitely without compromising sustainability or resorting to data monetization.

What happens if the recipient is offline?

If the recipient is not online to accept the direct P2P transfer, Perkoon offers the option to use encrypted cloud storage. This is a paid feature. The file is uploaded, encrypted on Perkoon's servers, and a link is generated. The recipient can then download the file at their convenience. This model honestly charges users only for the service component that involves Perkoon's operational costs.

Is my data private during a P2P transfer?

Yes. During a peer-to-peer transfer, an encrypted channel is established directly between the two browsers involved. The file data never touches Perkoon's servers. According to the principle of end-to-end encryption in direct connections, Perkoon has no technical ability to access, scan, or view the content of your transfer, ensuring maximal privacy.

Can AI agents or scripts use Perkoon?

Absolutely. Perkoon is built with automation in mind. It provides a CLI tool for terminal use and exposes a dedicated JavaScript API (window.__perkoon) in its web interface. This allows AI agents, bots, and custom scripts to authenticate, upload, download, and manage files programmatically without the inefficiency and fragility of simulating human interaction through web page scraping.

How does Session Stacker help with productivity?

Session Stacker helps enhance productivity by eliminating the time wasted on recalling previous tasks. By setting clear next steps at the end of each session, users can immediately dive back into work, maximizing their limited time.

Can I use Session Stacker on any device?

Yes, Session Stacker is designed as a Progressive Web App (PWA), which means it can be accessed and used on any device with internet capabilities, providing flexibility and convenience for users on the go.

Is there a free trial available?

Absolutely! Session Stacker offers a 7-day free trial with full access, allowing potential users to explore all features without the need for a credit card upfront.

What happens after the free trial ends?

After the free trial period, users can choose to subscribe for $4.99 per month or make a one-time payment of $49 for lifetime access. This ensures continued access to all features and updates without any surprises.
