The short version

  • Each has a real cost: Woebot Health the company withdrew its consumer app in June 2025 after concluding FDA marketing authorisation was not achievable at acceptable cost, which is a plain signal about both regulatory position and commercial durability.; Zanda Health the 2024 rename from Power Diary means most third party reviews, integration guides and community answers still sit under the old name, so buyers researching Zanda Health find a thin trail and may wrongly conclude it is a new and unproven product.
  • They diverge on capability: Woebot Health covers Scripted CBT dialogue, Zanda Health covers Unlimited admin users.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Woebot Health

  • The company withdrew its consumer app in June 2025 after concluding FDA marketing authorisation was not achievable at acceptable cost, which is a plain signal about both regulatory position and commercial durability.
  • It is not an FDA cleared treatment for any indication, so it cannot be positioned to members as therapy and cannot substitute for a covered behavioural health benefit.
  • The scripted, non-generative design that makes it safe also makes it feel rigid next to current conversational AI, and engagement drops off quickly once users hit the edges of the script.
  • Published evidence is short-horizon symptom change in selected populations, mostly young adults, with little evidence of durable benefit or effect at whole-population scale.
  • With consumer distribution gone, the remaining business depends on a small number of payer and provider contracts, so a buyer should assume real vendor continuity risk over a multi-year term.

Zanda Health

  • The 2024 rename from Power Diary means most third party reviews, integration guides and community answers still sit under the old name, so buyers researching Zanda Health find a thin trail and may wrongly conclude it is a new and unproven product.
  • North American billing is not properly served: there is no claims clearinghouse and superbill handling is basic, so a United States practice will need a separate revenue cycle tool and will pay for two systems.
  • Pricing is quoted in United States dollars while the company, support hours and product depth are Australian, so buyers outside those two time zones get support with an overnight lag on urgent clinical scheduling problems.
  • SMS is billed per message beyond the plan allowance and a dedicated number is required in the United States and Canada, so a busy clinic sending reminders and follow ups accumulates a variable monthly cost that is not visible in the headline plan price.
  • Reporting is adequate for a single clinic but weak for a group: cross site financial consolidation and practitioner productivity comparison generally end up exported to a spreadsheet, which becomes a monthly manual job as soon as you pass a handful of locations.

Answered from the vendors’ own pages

Woebot Health: Is Woebot still available?

Not to consumers. The consumer app closed in June 2025. The company continues to offer the product to payers, providers and researchers.

Zanda Health: Is Zanda Health the same as Power Diary?

Yes. Power Diary rebranded to Zanda Health in 2024. Same company, same product line, same data.

Woebot Health: Is it FDA cleared?

No. It held Breakthrough Device designation but never obtained marketing authorisation, and the founder cited the cost of that pathway as the reason for closing the consumer app.

Zanda Health: Do receptionists count as paid users?

No. On the Growth plan administrative users are unlimited and free. Only practitioners are charged.

Woebot Health: Is it generative AI?

Historically no. The dialogue is clinician-written and rule-based, a deliberate safety choice that limits how naturally it converses.

Zanda Health: Does it handle Medicare bulk billing?

Yes, Medicare Online, DVA and bulk billing claims are submitted from within the platform for Australian practices.

Woebot Health: What does the evidence show?

Randomised studies reported reduced depressive symptoms over short periods in selected populations, notably young adults. That is symptom change in a trial, not demonstrated population outcomes.

Zanda Health: Is it suitable for a United States practice?

Only partly. Charting, scheduling and telehealth work, but there is no claims clearinghouse, so US insurance billing needs a separate system.
