Key Takeaways
- Docs vs change diff with severity ranks.
- Actionable fix checklist — not silent auto-edits.
- Honesty: decision-support drafts — not an engagement guarantee.
URL first. Naming next.
Decision-support UTM hygiene — not an attribution suite.
UtmKit — definition
UtmKit turns a landing URL plus campaign fields into a GA4-ready tagged link with lowercase snake_case hygiene so marketers stop breaking attribution in spreadsheets.
What this is NOT
- Not a social network, ad network, or engagement guarantee.
- Not a promise of reach, followers, or sales.
- Not a substitute for your brand review before you post.
Controller / Processor — When packs mention privacy roles, we use GDPR Art.4 labels: Controller and Processor (decision-support only).

Your questions, answered
What does UtmKit draft?
Five platform-aware GA4-ready params — decision-support drafts, not an engagement guarantee.
Does this guarantee engagement?
No. Tagged URLs are decision-support. You still own taxonomy before you spend.
Can I cancel anytime?
Yes. Self-serve plans cancel anytime; access continues until period end.
Do I need a credit card to start?
No. Start with email signup or Demo mode in the studio, then upgrade when ready.
Do I need my own ChatGPT / OpenAI subscription?
No for Free/Pro. AI runs are included in your plan (fair use) via our platform key. Enterprise can optionally bring your own OpenAI key (BYOK) — configure it at /settings (key stays server-side only).
What is Fair Use / what if I hit the AI limit?
Free includes 3 AI drafts/day and 15/month. Pro includes 40/day and 300/month. At the fair-use limit, Studio returns a labelled demo until reset — or use Enterprise BYOK for heavier volume.
Is checkout secure?
Payments are processed by Waffo Pancake (merchant of record).
What happens after I pay?
You receive access confirmation; fulfillment is tracked via webhook + order logs.
