How much do Bach.ai and Birch cost?

Both price by ad spend. Birch’s slider steps up by bracket. Bach.ai adds 1% (Starter) or 1.5% (Pro) of spend above $10k to a $99 or $149 base. Both Bach.ai plans apply a fix only after you approve it; Pro adds unlimited audits and chat, creative generation and Guardian monitoring. Birch’s automated rules need its Pro plan. Monthly prices as of 1 Oct 2026:

Birch charges each bracket’s top price for any spend inside it: Pro is $249 anywhere from $10K to $30K, and $499 from $30K to $75K. Bach.ai adds 1% or 1.5% of the spend above $10k. Like for like, the comparison is Birch Pro, whose rules change the account, against Bach.ai Starter, which applies the fixes you approve. Up to $10K both are $99. Inside a bracket Bach.ai Starter costs less: $199 against $249 at $20K, and $399 against $499 at $40K. At the top of each bracket Birch Pro is cheaper: $249 against $299 at $30K, $499 against $749 at $75K and $799 against $1,499 at $150K, a gap that widens with spend. Bach.ai Pro costs more than Birch Pro at every level shown. Birch Essential is the cheapest column throughout, but it has no automated rules, so it changes nothing on its own. Above $150k a month, Bach.ai moves to its custom Agency plan, and Birch’s Essential plan stops at $150K while Pro continues. Both offer a free trial with no card: 14 days for Birch, 7 for Bach.ai.

What does Birch do better?

Rules and reach. “Rules are the engine Birch runs on”: nested conditions, custom metrics and 20+ actions, checked every 15 minutes. Birch AI drafts a rule from a sentence, Explorer spots fatigue and finds top assets, and you get bulk launches, post boosting, Slack alerts and white-label reports, across four ad networks. If you can write your playbook down, Birch executes it precisely, and its rules plan costs less than Bach.ai Pro at every spend level we checked, and less than Bach.ai Starter at $30K, $75K and $150K.

What does Bach.ai do differently?

Bach.ai starts one step earlier: it looks for the problem before anyone writes a rule. It audits the Meta account, ranks each finding by the money it costs, explains the reasoning, and executes the fix only after you approve it. It also checks pixel and Conversions API health and, from Starter, runs website intelligence on the pages your ads send people to. There is no rule logic to maintain, and no change happens without your approval.

When is Bach.ai the wrong choice?

Bach.ai is the wrong choice if you already know the conditions that matter and want them enforced every 15 minutes, or if you advertise on TikTok or Snapchat. In Bach.ai no change, from a rule or otherwise, reaches the account until you approve it; it covers Meta and Google Ads only, and costs more than Birch Pro at $30K, $75K and $150K on Starter, and at every spend level in the table on Pro. A small team with a clear playbook and a tight budget should start with Birch Pro, or with Ads Manager’s own automated rules.

Can you use Birch and Bach.ai together?

Yes, and the jobs don’t collide. Birch can run guardrail rules such as spend caps, pausing on hard CPA limits and scheduled budgets. Bach.ai can audit the account for what those rules can’t see. Watch one interaction: Meta may restart learning after a large budget change, such as $100 to $1,000 (Meta), so keep rule-driven budget steps small.

How do you decide in a week?

1. Export the last 30 days: in Ads Manager’s reporting table, click Export at the top right for a .csv baseline (Meta).
2. Write down the rules you would set in Birch. If you can’t name three, the audit is the better first step.
3. Note every ad set whose Delivery column reads “Learning limited” (Meta). A rule won’t fix those, but an audit should explain them.
4. Trial Birch (14 days) and Bach.ai (7 days) on the same account; neither needs a card.
5. Keep the tool whose output you acted on, and price it at your spend with the table above.
