01Rule engine
Any level of rule complexity.
From best-in-market rule presets for new teams — to any level of customization and complexity for advanced ones. Describe the strategy the way you actually run it, without splitting one idea into a dozen workarounds.
- Battle-tested presets — universal rule sets built and verified on real businesses. Start in minutes, tune later.
- Branching logic and sequences — one rule, several outcomes, ordered steps.
- Rule sets for scale days and cutback days — switch whole playbooks by schedule or by performance.
- One rule across many ad accounts — conditions evaluated everywhere at once.
- Day × hour scheduling — night watch and day push run different logic.
- Every kind of metric — platform, backend, formulas on both.
02Protection
Five layers stand between a bad number and your budget.
Each layer stops a failure we've seen burn real budgets, ours included. They run independently: four would have to fail before a wrong action reaches your account.
- 01
Rules pre-validation
Before a rule goes live: exposure preview of exactly what it will touch, conflict detection against your existing rules, and loop checks — so two rules never fight over the same budget.
- 02
Real-time data validation
No action runs on old or broken data. Every metric carries its freshness; a stalled or corrupted feed halts dependent rules — and you get the alert instead of the damage.
- 03
Cooldowns, caps & limits
Anything outside business-as-usual gets caught and stopped: per-run money caps, cooldowns between actions on the same object, hard spend limits per account.
- 04
Advanced alerting
Watches more than your rules: account-level performance anomalies raise alerts even when every individual rule looks fine — so nothing fails silently at scale.
- 05
Decision & execution log
For every object — why the rule fired, or why it didn't, and what exactly was done. Every move pushed to your analytics via webhooks and export.
03Data
Your data, wired straight.
Most tools see what the pixel sees. Your buying decisions live in your database — so that's where the rules should look.
The moment a purchase lands
Rules read users' LTV and backend purchases as soon as they hit your database — not hours later, when pixel events catch up.
A stalled feed can't spend your money
Every metric shows when it last updated. If data stops flowing, dependent rules hold and you're alerted first — before a stale number moves a budget.
04AI
AI that speaks performance marketing.
Describe the strategy in your own words — get draft rules back. The AI adapts thresholds to season and geo, finds conflicts and duplicates across your rule park, and keeps rules from going stale. It executes only what you approved.
Strategy → rules
Plain language in, reviewable drafts out.
Rule park audit
Conflicts, overlaps and dead rules surfaced automatically.
Adaptive thresholds
Proposed, never silently applied.
05Migration
AI moves your rules over — almost instantly.
Connect your ad accounts in a couple of clicks. The AI reads your existing automated rules — from Meta, Bïrch or your in-house system — and rebuilds them here in a couple of clicks, mapped to your metrics. Then run ZLIT read-only next to your current stack and compare decisions with your own eyes before you move a single budget.
01
AI-powered migration
Rules from Meta, Bïrch or your in-house system, moved in a couple of clicks.
02
Parallel by design
Nothing to uninstall, nothing to risk.
03
Side-by-side week
Read-only first: see where the engines disagree, then choose. From observing to full autonomy under caps — one step at a time.
06Build vs buy
Cheaper and more reliable than an engineer on scripts.
An in-house tool is never one sprint — it's maintenance forever: platform APIs change, scripts fail at night, the author eventually quits. We ship the same engine as a product — with SLAs, a full log and protection layers deeper than an internal team has time to keep alive.
Start free
Run your rules on your own numbers for 14 days.
Connect your accounts, let the AI migrate your existing rules and watch them run read-only next to your current stack. Or book a free 20-minute demo first: where your rules are blind to your economics, which ones conflict, and where your data goes stale.
