What is ButterShare?
ButterShare is a free, web-based peer-to-peer (P2P) file transfer platform engineered to solve the most frustrating bottlenecks of modern file sharing.
Most cloud-based file delivery platforms enforce restrictive ceilings. WeTransfer caps free transfers at 2GB and deletes your links after 7 days. Google Drive and Dropbox eat into your personal storage quotas and demand recurring monthly subscriptions just to hand off project files. Furthermore, traditional cloud services force your private files onto third-party datacenter disks, creating privacy vulnerabilities and forcing recipients to wait twice: once for the sender to finish uploading, and again for the recipient to download.
ButterShare replaces this outdated model with direct, real-time browser-to-browser streaming powered by encrypted WebRTC data channels.
Key Advantages:
• Unlimited File Sizes: Transfer 10GB, 50GB, 100GB, or even multi-terabyte datasets directly between devices without hitting size caps or paywalls.
• Complete End-to-End Privacy: Files are encrypted with DTLS/SRTP and stream directly from device to device. Zero bytes are stored on external cloud servers or central hard drives.
• True Cross-Platform Freedom: Send files between iPhone, Windows PC, Mac, Android, Linux, and Chromebook instantly without cables, iTunes, or installing third-party apps.
• Instant Room & QR Pairing: Generate a temporary 6-digit room code or scan a QR code with your phone camera to begin transferring immediately.
• Maximum Local Network Speeds: When both devices share the same local Wi-Fi router, transfers stream at full router throughput (up to 800+ Mbps) without consuming external internet bandwidth.
• Built-In Free Utilities: Includes bandwidth calculators, a WeTransfer limit checker, and cloud storage cost calculators to help users plan transfers and save money.
Whether you are a filmmaker sending ProRes video reels, a freelance designer delivering client assets, or simply someone wanting to AirDrop a batch of photos from an iPhone to a Windows laptop, ButterShare delivers seamless, private, and unlimited transfers right in your browser.
What problem it solves

What is Swifly?
Swifly is an AI dictation and voice typing app for macOS, Windows and iPhone. It converts speech into text so individuals and teams can write by speaking. Typical uses include drafting emails, composing messages, preparing documents and writing prompts for AI assistants. It is designed for people who want a voice-based way to produce everyday written content.
The core workflow starts with dictation: speak the text you want to write, then review the result before using it. This makes Swifly relevant to voice typing, speech-to-text and daily writing workflows. Someone preparing an email can dictate a first draft, check names and details, and refine the wording before sending it. Someone working on a document can capture a passage aloud and edit the resulting text as needed.
Swifly includes Magic Polish and Rewrite to help refine wording after dictation. Translation helps prepare text for another language. These features support the transition from spoken ideas to written material, while leaving the user responsible for reviewing the final text. Feature availability varies by platform, so users should check the current app and product information for their device.
A personal dictionary supports recurring names and specialist terms. Reusable snippets simplify repeated text, which can be useful when the same wording appears in multiple messages or documents. Together with dictation and rewriting, these features help organize recurring writing tasks for individual users and teams.
Swifly is available on macOS, Windows and iPhone. Its pricing model is freemium: a free Basic plan is available, alongside paid plans for individuals and teams. The official pricing page provides current plan details and limits. Dictation uses cloud processing and requires an internet connection; users should take this into account when choosing a tool for their working environment.
For people comparing AI dictation software or voice typing apps, Swifly offers speech-to-text with tools for refining, translating and reusing written content. Visit the official website to review supported platforms, current features and plan options before choosing the setup that fits your needs.
