In 60 seconds. Paste your message text before you send. Get a scored pre-check report — carrier-filter vocabulary, format and segment costs, TCPA/MMA consent text gaps, unsubstantiated claims, and sender-context advisories — based on the filtering patterns carriers and industry bodies publish and the text elements of the US wireless-texting rules. A heads-up, not a delivery guarantee. ## Capabilities - Five deterministic check families: carrier-filter vocabulary · format/structure & segment math · consent text gaps · claims/promises · sender-context advisories - Type and region escalation (marketing sends raise consent and claim severity; transactional sends lower scam-word phrasing to a warning; US sends escalate the missing-STOP gap to HIGH) - GSM-7 vs UCS-2 encoding detection with billed-segment math (160/153 per GSM-7 segment, 70/67 per UCS-2, newlines counted as one character, extension-set characters cost two septets) - Severity-ranked findings with quoted evidence from your own text - 0-100 filtering-risk score, grades: low_risk (>=85) · needs_edits (>=65) · high_risk (<65) - Actionable fix checklist; strictness filter (All findings / Medium+ / High only) - JSON + CSV export of run history (client-side) ## Not claimed (red lines) - Not a delivery or compliance guarantee — filtering, cost and legal obligations depend on carriers, aggregators, and recipients. - No sending, no number validation, no CPaaS or carrier connection: A2P 10DLC registration appears as an ADVISORY reminder only; nothing is looked up. - No list cleaning, no suppression management, no opt-out testing against your sender. - No replication of any carrier's internal filter model; references are a snapshot-dated reading of published guidance, not a real-time sync. - Not legal advice; the TCPA/MMA checks read text patterns, not your full campaign obligations. ## Pricing (machine-readable) - Monthly: $19/mo - Yearly: $190/yr (~$15.83/mo, save $38) - Full sheet: https://smsprecheck.lxsaihub.com/pricing.md - Checkout (monthly): `https://smsprecheck.lxsaihub.com/api/checkout?cycle=monthly` - Checkout (yearly): `https://smsprecheck.lxsaihub.com/api/checkout?cycle=yearly` - Waffo product IDs pending → checkout fails closed with a visible error until listed (intentional). ## FAQ (mirrored from the product's own content, `en.ts` / `product.ts`) Q1. What is SmsPrecheck? A1. A micro SaaS that pre-checks the SMS text you paste against published carrier-filtering patterns and TCPA/MMA consent text elements, and returns a scored, severity-ranked report with concrete suggested edits. Q2. Will a high score guarantee my text is delivered? A2. No. The engine flags documented text patterns; delivery also weighs 10DLC registration standing, consent records, send cadence and recipient behavior that a copy-only check never sees. Treat the report as triage, not a guarantee. Q3. Is this legal advice or a compliance certification? A3. No. Outputs are decision support. The TCPA/MMA checks read expected text elements (opt-out guidance, help path, rate disclosure, honest framing) — your full obligations for a real campaign, especially regulated sends, still need counsel. We claim no certification. Q4. Does it connect to my CPaaS account or carrier? A4. No. Paste-based only — no account access, no sending, no automation triggers. You apply every fix yourself. Q5. Does it check my 10DLC registration or sender status? A5. No — deliberately not. Those live in carrier registries, and SmsPrecheck performs no lookups. If your text reads like a bulk US marketing send, the report adds an ADVISORY line reminding you to verify brand/campaign registration in your own CPaaS console. Advisories are labelled and never presented as measured results. Q6. Can I cancel anytime? A6. Yes. Self-serve plans cancel anytime; access continues until period end. Q7. Do I need a credit card to start? A7. No. Start with the fair-use Demo (deterministic engine, labelled `Rule-based`) or email signup, then upgrade when ready. Q8. Do I need my own OpenAI subscription? A8. No for Free/Pro — live AI polish is included on a fair-use quota (Pro: ~300 runs/month, daily cap 40; Free: 3/day, 15/month). Exceeding quota returns a clear 429 with reset time — never a silent mock. Enterprise can bring your own key (BYOK) at /settings; the key stays server-side only. Q9. Is checkout secure? What happens after I pay? A9. Payments are processed by Waffo Pancake (merchant of record). You receive access confirmation; fulfillment is tracked via webhook + order logs. ## Policy references (snapshot 2026-10-22 — each link re-verified reachable from this build) - TCPA implementing rule (47 CFR 64.1200): https://www.ecfr.gov/current/title-47/chapter-I/subchapter-B/part-64/subpart-L/section-64.1200 - MMA text-messaging rule (47 CFR 64.1208): https://www.ecfr.gov/current/title-47/section-64.1208 - TCPA subpart in full (47 CFR Part 64, Subpart L): https://www.ecfr.gov/current/title-47/chapter-I/subchapter-B/part-64/subpart-L - CTIA mobile marketing guidance: https://www.ctia.org/our-work/advocacy/mobile-marketing - Messaging-platform docs (segment/encoding/10DLC background): https://www.twilio.com/docs/messaging - SMS technical specification lineage: https://www.openmobilealliance.org - UK consent authority (base URL only): https://ico.org.uk - Not included: FCC, GSMA, T-Mobile A2P and ETSI pages returned 403/000 from this build's network; the ICO deep marketing-guidance path 404'd (base only is cited).
