The short version

  • Each has a real cost: Rad AI the products are not FDA cleared devices and are not intended to be, so any claim that Rad AI improves diagnostic accuracy is unsupported; what has been measured is reporting speed and follow-up completion, not detection.; 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.
  • They diverge on capability: Rad AI covers Impressions, Woebot Health covers Scripted CBT dialogue.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Rad AI

  • A private radiology practice whose read volume has grown faster than it can recruit and that wants dictation time per study reduced without changing PACSnot Woebot Health
  • A health system losing revenue and exposing itself to liability because recommended follow-up imaging on incidental findings is never bookednot Woebot Health
  • A radiology department standardising impression quality across a mixed group of employed and locum radiologistsnot Woebot Health
  • A group deploying an AI tool that must not trigger a device validation programme, because governance capacity is already consumed by a triage algorithm rolloutnot Woebot Health

Woebot Health

  • A health plan wanting a low intensity behavioural health option for members on a waiting list for therapynot Rad AI
  • A provider organisation offering structured between-session CBT practice to patients already in treatmentnot Rad AI
  • A research group running a trial that needs a clinically scripted rather than generative conversational agent for safety reasonsnot Rad AI
  • A payer targeting a specific population such as postpartum members where scripted CBT content already existsnot Rad AI

Where each one falls short

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

Rad AI

  • The products are not FDA cleared devices and are not intended to be, so any claim that Rad AI improves diagnostic accuracy is unsupported; what has been measured is reporting speed and follow-up completion, not detection.
  • Generated impressions require radiologist review and signature, so the time saving evaporates in any group whose radiologists rewrite the draft rather than edit it, and adoption varies sharply by individual.
  • It is bound to your dictation platform, so a group planning to move off PowerScribe should sequence that decision first or expect to redo the Rad AI integration.
  • Continuity depends on the quality of recommendation language in historical reports, and departments with inconsistent phrasing get poor recall until reporting practice is standardised.
  • Pricing is not published and is structured per radiologist or per study depending on the product mix, which makes it hard to compare against image-analysis AI vendors that price per scan.

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.

Answered from the vendors’ own pages

Rad AI: Is Rad AI FDA cleared?

No, and by design. The products draft text and manage follow-up workflow rather than interpreting images, so they fall outside the device pathway. Treat any diagnostic accuracy claim with scepticism.

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.

Rad AI: Does the radiologist still sign the report?

Yes. Output is a draft that the radiologist reviews and signs; nothing is released autonomously.

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.

Rad AI: Which product actually pays for itself?

Continuity has the clearest financial case, because recommended follow-up imaging that gets completed is billable work that currently does not happen.

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.

Rad AI: Will it work with our dictation system?

It is deepest with Nuance PowerScribe. Confirm your specific dictation and PACS combination before contracting, because integration depth is the main deployment variable.

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.
