Frequently Asked Questions

Perkoon FAQ

Why is Perkoon free to use?

Perkoon operates on a P2P basis, which incurs minimal operational costs. The service is free because it does not rely on a central server for file transfers, making it sustainable without charging users for this feature.

How does Perkoon keep my data private?

Perkoon’s P2P transfers do not touch any central servers, meaning the files are sent directly between browsers without being stored or scanned. For cloud transfers, files are encrypted to ensure maximum privacy.

What happens if the recipient is offline?

If the intended recipient is offline, Perkoon uses its encrypted cloud storage to hold the files securely until the recipient is ready to receive them. This feature is part of the paid service, ensuring data remains safe during the transfer.

Which browsers are compatible with Perkoon?

Perkoon supports a range of popular browsers, including Chrome, Edge, and Brave, which allow for seamless file transfers. Users of Firefox and Safari should note that there may be some restrictions due to browser limitations.

voicebrief.io FAQ

How is Voicebrief.io different from simple text-to-speech apps?

Voicebrief.io is fundamentally different. While basic TTS apps merely read text aloud robotically, our AI comprehends the material and reconstructs it into a coherent, lecture-style narrative with natural pacing and emphasis. Crucially, it adds an interactive layer, allowing you to ask questions and receive explanations about the content, which no standard TTS service provides.

What types of documents can I upload?

The platform supports a wide range of document formats to suit your learning needs. You can upload standard PDFs (textbooks, research papers), images of pages, and even handwritten notes via Optical Character Recognition (OCR). You can also submit URLs to directly process online articles and reports.

Can I use Voicebrief.io offline?

The primary interactive features, such as generating new audio lectures and conversing with the AI tutor, require an internet connection for processing. However, once an audio lecture is generated, you can typically download it for offline listening, allowing you to learn anywhere, anytime.

Is there a limit to the length or complexity of documents?

Voicebrief.io is engineered specifically for long-form, complex content. It excels at processing dense textbooks and lengthy research papers, creating detailed lectures that can be one to three hours long to ensure comprehensive coverage. There are no artificial, short time limits that compromise depth.
