From scattered activity to one connected conversation workflow
Why the workflow matters
A lead list tells you who. LinkedIn activity gives you the context to start a relevant conversation.
Contact data, social monitoring, AI writing, and campaign tools are more useful when they share one relationship context. OpenComment connects those steps without taking the human out of the conversation.
Disconnected tools
Names in one place, alerts in another, drafts with no history, and outcomes that disappear after posting.
Context
Work from what a contact actually shared publicly, not a generic outreach template.
Timing
Use Monitoring Rounds to create a deliberate rhythm instead of relying on one-off alerts.
Continuity
Keep replies, reactions, impressions, and previous conversations attached to the relationship.
One connected workflow
Find the right people. Join relevant conversations. Build on every interaction.
OpenComment connects contact discovery, multi-round LinkedIn engagement, and public relationship history—while every posting run stays explicitly user-started and bounded.
Engage
Join relevant conversations
Use multi-round campaigns to surface public LinkedIn activity, then review suggestions individually or start a bounded Auto Submit run.

Bring public replies, reactions, impressions, and prior conversations into the next touch.
Multi-round campaigns
Plan more than one meaningful touch.
Build a linear series of Monitoring Rounds for saved contacts or Contact Lists. Each round gives your team another scheduled window to review relevant public activity and decide whether to join the conversation.
- Create a clear sequence instead of a pile of disconnected tasks.
- Keep the post, suggestion, decision, and outcome connected to the contact.
- Measure conversation signals across the campaign without claiming intent that is not there.

Human control by design
AI prepares the context. You decide what gets posted.
OpenComment drafts from the public post and your comment profile. Review suggestions individually, or explicitly start a bounded Auto Submit run up to your selected comments-per-run limit. OpenComment does not start or schedule a posting run on its own.
Comment suggestion
Based on a public original post
The way you separated the customer problem from the feature request is useful. It makes the trade-off much easier to discuss.

How do credits work?
Credits power contact discovery, public activity checks, and AI-assisted comment preparation. Each plan includes a monthly allowance that resets with the billing cycle; unused credits do not roll over.
Can I upgrade or downgrade my plan?
Yes. You can change plans from billing settings. Upgrades take effect immediately according to the checkout terms, while downgrades apply at the next billing period.
Do you offer monthly and annual billing?
When both intervals are available, you can choose monthly or annual billing in this section. The displayed live price is the authoritative price for each interval.
Can I start for free?
Yes. The Free plan includes 100 monthly credits and requires no credit card, so you can explore the workflow before choosing a paid plan.
What happens when I cancel?
You can cancel from the billing portal. Your paid plan remains active through the current billing period, and you can contact support about export, reactivation, or deletion requests.

OpenComment is designed around public activity, explicit user control, and a connected B2B conversation workflow.
Contact supportWho is OpenComment best for?
OpenComment is built primarily for founder-led GTM, relationship-led sales, and social or brand teams that want to use public LinkedIn activity as context for relevant B2B conversations.
How can I bring contacts into OpenComment?
Use Apollo, Manual Import from CSV, Excel, or LinkedIn URLs, Keyword Search, Conference Search, or AI Discovery. You review candidates and save selected contacts into Contact Lists before campaign use.
What is a multi-round campaign?
It is a linear sequence of scheduled Monitoring Rounds for saved contacts or Contact Lists. Each round creates another opportunity to review relevant public original or quote posts and decide whether to engage.
Does OpenComment start posting on its own?
No. You explicitly start each Chrome extension run. With Auto Submit enabled, that user-started run can submit prepared comments up to the selected comments-per-run limit without a separate click for every comment.
Does OpenComment need my LinkedIn credentials?
No. OpenComment does not ask for your LinkedIn username or password. Every posting run is explicitly started and controlled through the Chrome extension.
What LinkedIn activity does OpenComment use?
OpenComment works with publicly available LinkedIn activity, including public original and quote posts. It does not claim access to private messages or private profile activity.
Can I use Post Monitor without a campaign?
Yes. Post Monitor is a standalone service. Organize people in Monitor Lists to maintain social activity, keep in touch with clients, follow important voices, or observe public competitor activity.
Can suggestions reflect how I want to sound?
Yes. Comment profiles let you define useful style and persona context. Suggestions stay reviewable before individual use or inclusion in a bounded Auto Submit run.
