Hospitality · Dallas, TX · Posted May 22, 2026
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.

Also from one brief · Long-form
Articles and reports. Cited, charted, export-ready.
Sigil writes blog articles and 5 to 10 page reports with a research pass behind every claim: live web sources plus academic papers from Europe PMC, OpenAlex, and arXiv, screened by a relevance judge that would rather cite nothing than cite junk. Pick the angle: brief-led, both sides, for, against, or data only. Reports ship with an executive summary, numbered references, stat callouts, and charts drawn from verified numbers. Export as Markdown or print-ready PDF.

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.
Can Sigil write blog articles and long reports?+−
Yes. Blogs and reports are a first-class format next to social posts. Articles run 800 to 1500 words; reports run 2500 words and up with an executive summary, numbered references, stat callouts, and charts drawn only from verified research numbers. Both export as Markdown, plain text, or print-ready PDF. Customers can request them from the portal with an angle (both sides, for, against, or data only) and optional academic citations.
Where do the citations come from?+−
A research pass runs before writing: live web search plus academic databases (Europe PMC, Semantic Scholar, OpenAlex, arXiv) routed by topic. A relevance judge screens every paper and drops keyword-only matches. If nothing genuinely supports the topic, the article ships without citations rather than inventing them. Every kept source is listed in the review panel with authors, venue, year, and citation count.
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.
