// THE WEDGE = the closed loop

Sigil is the only platform that learns from each brand's published engagement and feeds it back into the next brief, automatically.

// HOW IT WORKS

Brief in. Tuned posts out. Engagement back in.

Six months in and the room finally feels like itself. We rebuilt the menu around what people actually order, not what a consultant thought they should. The May Tuesday menu launches this week: three blends, three plates, all of them on the wall for a reason. If you're in Dallas and you've been waiting for us to settle in, this is the week. From all of us at Crossbar & Cactus, thanks for the patience.

// QUESTIONS

FAQ.

How does Sigil learn from my brand?+
Sigil ingests your brand kit (voice, glossary, references, banned terms) once. Every published post's engagement (likes, comments, shares, click-through) feeds back into the next brief's context. After roughly 30-50 posts the voice tightens measurably; by week 12 you'll notice Sigil anticipating your tone rather than approximating it.
What platforms can it publish to?+
X, LinkedIn, Instagram, Facebook, Threads, TikTok, YouTube. New platforms ship monthly. You can also use Sigil as a draft-only studio and publish manually. The Critic still runs; you just approve and post yourself.
What does the Critic actually check?+
18 rules across three domains: voice (no superlatives, tone match, emoji cap, slang blocklist), platform (character limits per tier, image-text overflow, hashtag count), and brand-safety (banned terms, factual claims, reference-asset match, competitor mentions). Every rule can be toggled per brand.
What if the Critic blocks a post?+
Two paths: auto-correct (Sigil regenerates with the violation flagged inline, usually 1 retry, costs ~$0.003) or human review queue. Composer defaults to manual review so you stay in the loop. Bulk-import via CSV defaults to auto-correct, which you can override per row.
How much does it cost to run?+
Generation cost depends on your model mix. With Sigil's default Config D (DeepSeek text + gpt-image-2 visuals), a typical 3-platform post runs ~$0.04 in direct API cost. Platform fee scales from a pilot tier to full enterprise. Contact us for current pricing during alpha.
Can I export my data?+
Yes. Full CSV export of posts, drafts, engagement, brand kit, and audit trail. Standard tenancy controls apply (workspace + brand membership with owner/admin/member/viewer roles). SOC 2 Type II is in progress.
