Plumline · AI social studio
Always-on AI agents.A human sets the line every week.
Plumline is an always-on social studio for small brands — agents ideate, draft, schedule and publish, draft on-brand replies, and ship the weekly report straight to your inbox. Once a week a strategist reviews the line, confirms voice, and approves the replies that need escalation.
- Always-onAgents ideate, draft, schedule and publish overnight.
- Human-lineA strategist reviews the full week before it ships.
- CompliantFTC disclosure + EU AI Act labeling handled by escalation.
- Sub-$80Priced for SMB — not the agency retainer you’re escaping.
The loop
Four steps. One human checkpoint. Calm social.
The agents own the grind. A strategist owns the line. You own the brand.
- 01
Brief the day
Onboard in an afternoon — drop in your tone, your offers, what to avoid. Agents inherit it.
- 02
Agents run the lane
Ideate, draft, schedule and publish across channels around the clock. Comments get a first pass.
- 03
Escalate the ones that matter
Replies needing FTC disclosure, EU AI Act labels or a sensitive judgment get routed to your strategist.
- 04
Weekly line check
A 15-minute review. Confirm voice, tune next week, approve replies — never wonder what posted.
What you get
The “full social team” — without the agency retainer.
Every Plumline flavor of “always-on” lives or dies on whether the work still feels like you. The loop below is what keeps it on-rails.
Drafts that read like you
Voice trained on the posts you already approve. The first batch is ready before lunch.
A calendar that fills itself
Seven-day cadence set from your offers, launches and seasons. Editable. Never auto-something.
Comments triaged 24/7
Replies drafted by agents, escalating only the ones that need a human judgement.
The weekly report in your inbox
Reach, replies, what converted. Plain numbers and one sharp recommendation.
Built for solo founders
DTC, agencies serving SMBs and local shops — anyone who wants reach of a full social team without the retainer.
Stays in voice after month three
No drift, no “wait why did it say that?” — the weekly line-keep keeps the brand aligned with the brand.
Tightening rules reward teams who check the work — not skip it.
Auto-reply is being clamped on Meta, X and TikTok. FTC disclosure and the EU AI Act are pulling labels in. Plumline’s weekly line check turns those into a routine, not a future emergency.
Disclosure that holds up
Material connections, sponsorship and AI-generated assets get a plain-language label — agents draft, a human approves.
Replies’ that respect the channel
No auto-replies to DM threads. No blanket “Thanks!” on Meta. No canned replies that ignore context.
Voice that doesn’t drift
Every post is judged against the brand line at the weekly review. Drift gets caught in the same pass that approves the rest.
A line of audit, not mystery
Every reply and post has a trace: who drafted, who approved, where it shipped.
