Welcome, friend. Here's Aster in action.

This is the same walkthrough we run live with design partners — a real workflow, scene by scene, the way it would actually unfold in your Slack.

SCENE 01
The trigger.

Kevin, the CMO, mentions the newsletter again. He's been saying this in some form for months. The team isn't getting to it. Aster is already in the channel — quiet, listening, no plugin to launch, no dashboard to open. This is the entire user action.

we should really get the weekly newsletter going again. last one was 9 months ago 😬 the audience is cold at this point
SCENE 02
Aster finds the candidates.

Within seconds, Aster has searched open agent marketplaces, normalized the candidates, filtered by domain fit (B2B SaaS, compliance vertical), and surfaced the top matches. Cost, frequency, quality grade — all visible before anyone commits to anything.

I scanned 87 newsletter agents across open marketplaces and shortlisted 4 that fit your domain. Here are the top picks:
★ postcraft.ai
$4 / draft · weekly · 4.7★ across 1.2k runs
briefly.so
$7 / draft · weekly · 4.5★ across 800 runs
letterloop.ai
$12 / draft · biweekly · 4.6★ across 2.1k runs
digest.work
$3 / draft · weekly · 4.2★ across 400 runs
SCENE 03
Side-by-side comparison.

Kevin clicks "Compare all 4." Aster expands the breakdown — same six dimensions, side-by-side. No hunting through agent pages. No pricing surprise.

My recommendation: postcraft.ai — second-cheapest, highest quality, fastest. Want me to start a sample draft from your last 8 blog posts and the #product-updates channel?
SCENE 04
Kevin hires the agent.

One click. Aster handles the rest — registering the agent for the workflow, configuring the run schedule, setting up the validation pass, and pulling the source context from the team's Slack history.

yes, start sample
Aster10:44 AM
On it. I'm setting this up as a weekly run, Tuesdays 9 AM, pulling source from your product updates and recent conversations. Estimated monthly cost: $20 in agent + Aster fees ($4/draft × 4 runs, plus 25% fee). Your subscription covers the orchestration layer.

I'll have the first sample draft back in 6 minutes for you to review.
SCENE 05
The draft lands.

Six minutes later. Validated draft drops in-thread. Kevin reviews, edits two lines, hits approve. The newsletter goes out — the first one in nine months.

SCENE 06
Six weeks later. Aster spots a better agent.

This is the part most people don't see coming. Aster keeps watching the supply. When a better-fitting agent appears — same domain, higher quality grade, lower cost — Aster surfaces it. The team decides whether to switch. The asset compounds.

Heads-up. A new agent dropped this week, edgeletter.io, scoring 4.8★ on compliance-vertical newsletters (postcraft is 4.7★). Same $4 cost, slightly faster. I ran a parallel sample on last week's source — output side-by-side below. Want to switch, run them in parallel for two cycles, or stay on postcraft?
