Verke vs. Sonia: five specialist coaches and 55 languages vs. a structured 6-week GAD program

Two honest angles: a focused anxiety arc vs. a wider coaching surface.

Sonia is a Y Combinator–backed iOS app built by three ETH Zürich computer-science graduates, centered on a structured 6-week program for generalized anxiety. It offers voice or text sessions of 5–30 minutes with six selectable AI personas — variations in gender, age, and style that all draw from the same CBT-styled playbook. Verke takes a different shape: five named specialist coaches — Anna (PDT), Judith (CBT), Marie (EFT/NVC for couples), Amanda (ACT/CFT), and Mikkel (executive) — each trained in a substantively different method, plus phone-call-style WebRTC voice, end-to-end encryption, 55 localized UI languages, and an ongoing 3-arm randomized controlled trial at Stockholm University. Participants in that trial most often described the value as a non-judgmental space available whenever it was needed, rather than a fixed program to complete. Verke is an AI coaching app, not a therapy replacement — we call our specialists coaches because that's what they are.

Verke is an AI coaching app with five specialist coaches trained on evidence-based therapeutic methods (CBT, PDT, ACT, EFT, CFT, NVC). Chat in text or switch to voice for a phone-call-style session; pick up again days later with memory that survives across weeks and months. Conversations are end-to-end encrypted, signup is anonymous, and the product is available on iOS, Android, and Web in 55 languages.

The five coaches are differentiated on purpose. Anna works in a psychodynamic register — slower, pattern-first, interested in why the same kind of situation keeps returning. Judith is CBT — small experiments, thought records, gradual exposure — and is the natural starting point for users coming in with social anxiety or generalized worry. Marie supports couples through Emotionally Focused Therapy and Nonviolent Communication; Amanda blends Acceptance and Commitment Therapy with Compassion-Focused Therapy for overwhelm and self-criticism; Mikkel is an executive coach for decision fatigue and leadership load. Users pick who fits the concern, rather than asking one bot to cover everything.

The difference between methods is not cosmetic. In the Stockholm RCT, participants working in the PDT arm with Anna most often valued the recognition of patterns connecting seemingly separate issues — the sense of a coach who remembers what came up two weeks ago and notices when it returns in a new shape. Participants in the CBT arm with Judith most often valued the breaking down of an overwhelming problem into small, concrete steps they could actually do that day. Both also described the experience as easier to be honest in than they expected — no performance pressure, no managing how the coach feels about what was said. Choosing a method is choosing the kind of work, not the look of the avatar.

Sonia is a Y Combinator–backed (S23) AI mental-health app at soniahealth.com founded by three ETH Zürich computer-science graduates — Dustin Klebe, Lukas Wolf, and Chris Aeberli — who are explicitly not clinicians. The product centers on a structured 6-week program for generalized anxiety disorder, with voice or text sessions of 5–30 minutes, six selectable AI personas (varied gender, age, ethnicity, and style), a per-session emotional resilience rating, and a summary illustration after each session. Pricing is $19.99/month basic, $39.99/month premium, or $199.99/year, with a 7-day free trial. Sonia is iOS-only at launch, English-only, and not FDA-cleared. Funding to date is $3.35M (YC, Moonfire, Rebel Fund, SBXi); roughly 8,000 users at launch per TechCrunch.

Sonia is the honest pick if you want a defined, structured arc rather than open-ended coaching. The 6-week generalized-anxiety program with weekly stress visualizations, homework assignments, and after-session summary illustrations is the most concrete GAD-specific product on the market right now, and if you respond well to that kind of scaffolding it's a real strength. Sonia is also the right call if you specifically want to choose between several stylistic AI persona presentations and don't need a coach trained in modalities other than CBT. Sonia uses “therapy” framing in its persona language; Verke uses “coach” — see our research page for why that distinction matters to us.

Verke is built for people who want a coach matched to a specific concern, not a generalist program. If you're working on social anxiety or generalized worry, Judith (CBT) runs the small experiments, thought records, and gradual exposures that map most directly onto Sonia's territory — the kind of decomposition of an overwhelming problem into small, doable steps that participants in the Stockholm trial named most often as the single most useful thing about coaching that week. For old relational patterns there's Anna (PDT); for couples work, Marie; for acceptance and self-compassion, Amanda; for high-pressure leadership, Mikkel. Voice coaching in a phone-call format is core to the product, end-to-end encryption is built in rather than marketed, and Verke is the subject of an ongoing Stockholm University trial supervised by Professor Per Carlbring. Read the method explainer for Cognitive Behavioural Therapy — it's the closest direct comparison to Sonia's 6-week arc.

Choose Verke if the work you want is shaped less like a six-week curriculum and more like an ongoing thinking partnership — somewhere to be honest about how things actually feel, to notice patterns across weeks rather than tick boxes within one program, and to reach for support in the moments when something is hard rather than at the next scheduled session. Choose Anna over Judith if what you most want is to understand why the same kind of situation keeps returning; choose Judith over Anna if what you most want is concrete structure and steps you can apply this week. Both are different from picking between stylistic variants of the same bot.

Three practical differences are worth calling out. First, language: Verke runs in 55 fully localized UI languages, while Sonia is English-only. If you want to coach in Swedish, Spanish, German, Japanese, or any of the other 51 supported locales, Verke is the available option. Second, platforms: Verke runs on iOS, Android, and Web, while Sonia is iOS-only. Third, privacy: Verke is end-to-end encrypted with AES-256-GCM and RSA-4096, anonymous signup, and keys that never leave your device — Sonia's data handling specifics are not published.
