The Keep social-comment extension
Draft thoughtful comments on LinkedIn, Facebook, and Instagram posts — review before posting.
TL;DR. Keep drafts thoughtful comments on LinkedIn, Facebook, and Instagram posts using your Business Context + the post content. Preview before posting; Keep never auto-comments.
When to use this
When you commit to a consistent social-engagement rhythm — commenting on prospects' posts to stay top-of-mind without spamming. Keep makes it fast enough that it's actually sustainable.
Step-by-step
- Install Keep from the Chrome Web Store. See Install the extensions.
- Open your LinkedIn (or Instagram / Facebook) feed.
- Each post gains a "Generate comment" button below it (next to the platform's native Like / Comment / Share actions).
- Click it. A small panel shows the proposed comment.
- Edit if needed. Hit Copy to copy to clipboard, then paste into the post's comment box. (Or Use to auto-fill the platform's comment input where possible.)
- Post from the platform's own UI. Keep never auto-posts.
What makes a good comment
Keep's prompts are tuned to avoid spammy patterns. The default style:
- Lead with a specific reaction to the actual post content (not "Great post!")
- Add a personal angle when relevant (your experience, a counter-example, a question that extends the conversation)
- Keep it short — 1–2 sentences for casual posts, 3–4 for longer thought pieces
If the default style isn't right, set a custom prompt in /keep — same mechanism as the master prompt for Connect.
Common questions
Does Keep work on every platform? LinkedIn, Facebook, and Instagram feeds. Twitter / X is on the roadmap but not shipping yet.
Can Keep generate replies to comments on my own posts? Not in V1 — the extension currently only generates top-level comments on other people's posts. Replying to comments on your own posts is on the roadmap.
How do I avoid sounding like a bot? Two things: write a custom prompt that captures your voice (short sentences, your common expressions, things you'd actually say), and always edit before posting. The AI is a starting point, not a final draft.
