About
PostMaster is a desktop application for effortless and private social media management.
Perfect for freelancers, creators, and small businesses, it makes post creation and publishing faster, easier, and more secure. You choose the workflow: write posts manually or use AI models (Gemini, GPT, Claude) to generate content in seconds.
With one click, you can publish across platforms — saving time while staying in control. Because PostMaster runs locally on your computer, your data never leaves your device. No cloud, no spying, no risks — just a privacy-first tool built for efficiency.
Key Features:
✍️ Flexible Post Creation – Write manually or use AI for instant content
🚀 One-Click Publishing – Publish directly, without extra steps
💻 Desktop-Only – Works locally, no cloud storage required
🔐 Privacy-First – Your posts and data remain on your computer
💸 Transparent Pricing – One-time license + pay-as-you-go AI tokens
🎁 14-Day Free Trial – Try all features before you buy

About
Riff is a free Chrome extension that uses Gemini Nano on the user's computer to draft social-media replies, posts, and direct messages for creators, founders, marketers, and other professionals. On X, LinkedIn, Facebook, and Instagram, users can provide rough notes, adjust tone, and generate a draft tailored to a post or conversation. Riff also helps draft new posts and first messages, and replies to messages in LinkedIn Messaging, Facebook Messenger, and Instagram Direct. Users can configure a personal or brand voice, revise the draft, then insert and send or publish it themselves. Riff runs Gemini Nano locally in desktop Chrome and stores settings and drafts in Chrome storage on the computer. It requires compatible Chrome and hardware plus a one-time model download; it does not send posts on the user's behalf.
