Soku AI
Stop writing rules. Start getting diagnoses.
Revealbot — now Bïrch — executes the rules you write, reliably, every 15 minutes. Soku AI reads the account, works out why performance changed, proposes the specific fix with its reasoning, and acts only when you approve.
Soku vs Revealbot (Bïrch)
Both automate paid media across multiple platforms. They differ on how a decision gets made, whether creative is produced, and how much of the work you have to specify in advance.
| Feature | Soku | Revealbot (Bïrch) |
|---|---|---|
| Automation model | Agentic — diagnoses the account, proposes a specific action with reasoning | Rule-based — conditions and actions you define, fired on a schedule |
| Ad platform coverage | Meta, Google, TikTok, Reddit, Pinterest, Snapchat | Meta, Google, Snapchat, TikTok |
| Rules engine depth | Approval-gated actions rather than a rule builder | Yes — 20+ actions, nested AND/OR, metric-to-metric and ranking conditions |
| AI ad creative generation | Yes — image and video ad variants | No — boosts and launches assets you already have |
| Autonomy control | Four modes: Observe, Recommend, Act with approval, Full autopilot | Rules run automatically once enabled; pre-built strategy bundles available |
| Decision transparency | Every decision logged with its reasoning | Automation logs showing which items each rule affected |
| Bulk ad launching | Yes — generates and deploys variants across channels | Yes — up to 50 ads per ad set with macro tagging |
| Client reporting | Cross-channel reporting in-app | Yes — scheduled, white-label, Slack alerts, custom metric builder |
| Competitor ad research | Explorer surfaces your own top performers and fatigued ads, not competitors | |
| Chat-driven interface | Yes — ask questions about the account in plain language | No — rule builder and dashboards |
| Free to start | Yes — free tier, no credit card | 14-day free trial, no credit card, then from 49 USD/mo |
| Entry pricing | Free, then 49 USD/mo Starter and 249 USD/mo Pro | Essential 49 USD/mo, Pro 99 USD/mo at up to 10K USD monthly spend; scales with spend |
Bottom line: Choose Bïrch if you already know exactly which rules you want and value deterministic, auditable execution above all. Choose Soku if your bottleneck is working out what to do — and producing the creative to do it with — rather than executing a decision you have already made.

Why teams move from Bïrch to Soku
A rule tells you what happened, not why
Pause when ROAS drops below 1.5 is a correct rule and a silent one. Creative fatigue, an audience shift, a broken conversion event and a seasonal dip all trip the same condition and all need different responses. Soku separates the symptom from the cause before it proposes an action.
Rule sprawl has a real maintenance cost
Fifty rules across six accounts eventually contains contradictions nobody has audited. Because Soku reasons about the account state rather than executing a static rule set, there is no rule library to keep consistent as the account changes.
Creative is the lever, and Bïrch does not pull it
Bïrch is excellent at rotating and boosting the assets you already have. It does not make new ones. Soku generates image and video ad variants, so the response to creative fatigue is new creative rather than just pausing the tired ad.
Autonomy should be a dial, not a switch
Soku runs in four modes — Observe, Recommend, Act with approval, and Full autopilot. You can start it read-only on a live account, watch what it would have done for a fortnight, and only then hand over execution.
Ask a question instead of building a query
What changed in this account last week is a sentence. In a rules engine it is a reporting configuration. Soku is chat-driven, so investigating an account does not require knowing in advance which metric to look at.
Moving from Bïrch to Soku
Run both in parallel first. Soku's Observe mode is designed for exactly this — it will not touch anything while your existing rules keep running.
Export your rule library
Before you cancel anything, list every active rule in Bïrch with its conditions, actions and schedule. This is the specification of what your account currently guarantees, and it is worth having written down regardless of which tool you end up using.
Connect your ad accounts to Soku in Observe mode
Connect Meta, Google, TikTok and any other channels on the free tier. In Observe mode Soku reads the accounts and reports what it sees without taking any action, so it is safe to run alongside a live Bïrch setup.
Compare recommendations against your rules for two weeks
Switch Soku to Recommend and let it propose actions while Bïrch continues to execute yours. The useful signal is the disagreements: cases where Soku diagnosed a cause your rule could not see, and cases where your rule caught something worth keeping.
Move the judgement-heavy rules over first
Keep the genuinely mechanical rules — hard spend caps, dayparting, safety stops — wherever they are today. Move the ones that were always a proxy for a judgement call, such as creative fatigue and budget reallocation, to Soku with approval gates.
Turn on creative generation
This is the part with no equivalent in Bïrch. Once Soku is diagnosing fatigue, let it generate the replacement variants rather than only pausing the tired ad, and review them before they go live.
When each tool is the right answer
You have a proven rule set — stay on Bïrch
If your team has spent two years refining rules that reliably protect and scale the account, that is real institutional knowledge encoded in a mature engine. Do not throw it away for novelty.
You are rebuilding after a media buyer left — use Soku
Inheriting an account with fifty undocumented rules is the worst case for a rules engine and the best case for an agent that reads the account from scratch and tells you what it finds.
Creative fatigue is your main failure mode — use Soku
Ecommerce accounts that burn through creative faster than they can replace it need generation, not just rotation. Pausing a fatigued ad without a replacement is a budget cut, not an optimization.
You need white-label client reporting — Bïrch is stronger today
Bïrch's scheduled white-label reports, Slack alerts and custom metric builder are a mature agency reporting stack. If client deliverables are the job, weigh that seriously.
You want to start free and prove it on your own data — use Soku
Soku has a free tier with no credit card, so you can connect a real ad account and see genuine recommendations before committing. Bïrch gives you 14 days.
Revealbot (Bïrch) alternative FAQ
Is Revealbot the same as Bïrch?
Yes. Revealbot rebranded to Bïrch and the product now lives at bir.ch. Both names still appear in the market and in review sites, and they refer to the same ad automation platform.
What does Bïrch cost in 2026?
Essential starts at 49 USD per month and Pro at 99 USD per month at the entry ad-spend tier of up to 10K USD monthly spend, with pricing scaling as your spend grows and custom Enterprise pricing above that. There is a 14-day free trial that does not require a credit card.
Which ad platforms does Bïrch support?
Meta Ads, Google Ads, Snapchat Ads and TikTok Ads. Soku covers Meta, Google, TikTok, Reddit, Pinterest and Snapchat.
Does Bïrch generate ad creative?
No. Bïrch launches, rotates and boosts creative you already have, including automatically promoting high-performing organic Instagram and Facebook posts. It does not generate new images or video. Soku does.
Is an AI agent safer than a rules engine?
Not automatically, and it is worth being sceptical here. A rule is deterministic and auditable, which is a genuine safety property. Soku's answer is the approval gate — in Recommend and Act-with-approval modes nothing changes in your account without a human saying yes, and every decision is logged with its reasoning.
Can I run Soku and Bïrch at the same time?
Yes, and for the first two weeks you probably should. Soku's Observe mode is read-only, so it can analyse an account that Bïrch is actively managing without interfering.
What is Bïrch genuinely better at?
Deterministic rule execution, the depth of its rule builder with nested conditions and ranking-based logic, and its white-label client reporting stack. If those are the centre of your workflow, Bïrch is a strong product and we would rather say so.
