Find what
needs attention.
“Where am I spending without results?” Use campaign reports and account audits to focus your review. Ask the AI analyst, when available, to help explore what to check next.
ROAS uses platform-attributed revenue. It’s a signal to investigate, not a promise of growth.
Spot the signals.
Stay in control.

What is Lethir?
Lethir helps you understand where your Google and Meta ad budget goes and decide what to do next. Bring campaign reports, account audits, drafts, and changes you approve into one workspace, with AI-assisted analysis when available.
How does the AI analyst work?
Ask questions about your latest synced campaigns to get a clearer view of spend, conversions, and reported return. When AI analysis is available, the analyst summarizes the data and suggests what to investigate next. Account audits also flag active campaigns spending without attributed conversions. You approve any campaign or budget changes.
Is AI analysis available in every workspace?
Your workspace shows whether AI analysis is available. If it is unavailable, you can still view a basic campaign summary and run account audits. Contact support@lethir.com if you need help.
Can Lethir run my ads on autopilot?
You stay in control. Campaign status and budget changes go through a review queue and require your approval. New campaigns start paused. You can refresh reports yourself or opt in to daily account-health monitoring. Monitoring only reads performance data; it does not change or optimize your ads.
Do I need to connect an ad account right away?
No. Sign in to set up your workspace, then connect Google Ads or Meta when you’re ready. Performance reports require a connected account and a successful sync.
How do I sign in?
Enter your email to receive a secure, single-use sign-in link. No password to remember.
Which platforms can I connect?
Google Ads and Meta Ads. Sign in to the platform, approve access, and choose an ad account you manage. You can create Google Search and Meta website-traffic campaign drafts in Lethir.
What does return on ad spend tell me?
ROAS compares platform-attributed revenue with ad spend. Platforms can use different attribution settings and account time zones, so treat it as context for a decision, not proof of incremental growth.
