Riff
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.

Voxlio.ai
Voxlio.ai writes, reviews, designs, and schedules LinkedIn posts.
You set your voice once: role, audience, tone, and content pillars. Every post then runs through an AI council. A writer agent drafts it, a reviewer agent scores it, and an editor agent tightens it. The system also creates the image or carousel and checks it for readability and brand fit.
You approve the finished post, then schedule it or publish it. Publishing uses LinkedIn's official API, so no browser extensions or session tokens are involved. Nothing goes live without your approval.
Autopilot prepares upcoming posts from your strategy and posting frequency. A content calendar plans weeks or months ahead. Topic suggestions surface ideas matched to your pillars. Agency plans run up to 5 client workspaces, each with its own LinkedIn account, voice profile, and client approval links.
The free plan includes 15 AI credits a month with no card. Pro is $19.99/month, Agency $69.99/month.
