Mohammed Ali ChherawallaHow behavioral health organizations ship HIPAA-compliant local AI in mobile apps — session notes, risk screening, and documentation without cloud exposure.
Your behavioral health clients will not consent to their session content being processed by a cloud LLM. Your clinicians spend 40% of their session time on documentation.
Both facts are true simultaneously, and they point in the same direction. A local model that processes session content on the device resolves the consent problem and the documentation burden at once. The question is which tasks to build first and how to build them without running into a compliance wall six weeks in.
Four decisions determine whether this project ships a tool clinicians actually use or a compliance risk they avoid.
Which AI tasks run locally. Session note summarization, risk screening prompts, and diagnostic coding assistance each require different model sizes and carry different PHI exposure profiles. A model fine-tuned for summarization will produce poor results on structured risk screening outputs. Treating them as one task produces a model that serves none of them well. Starting with the single highest-value task for your clinician workflow delivers something usable in the first sprint.
Consent and disclosure model. On-device processing doesn't eliminate the disclosure obligation. Your compliance and legal teams need to agree on what the disclosure language says before the feature ships. Getting this wrong doesn't mean a slow launch - it means a retraction after launch, which is worse for clinician trust than not shipping at all.
Platform. Therapists in private practice skew iOS. Case managers and community mental health workers skew Android. The platform with the faster on-device AI runtime determines which clinician group you can serve in the first release. Starting with the wrong platform means your first user cohort is the one that experiences the worst performance.
EHR integration. A local AI that assists with documentation but doesn't write back to the clinical record creates a parallel workflow. The clinician gets a summary they then have to copy into the EHR. That's not a time saving - it's a second documentation step. The integration architecture determines whether this project reduces the documentation burden or adds to it.
Most teams spend 4-6 months discovering these decisions by building the wrong version first. A team that has shipped this before compresses that to 1 week.
We built Off Grid because we hit every one of these problems in production. Off Grid is the fastest-growing on-device AI application in the world, with 50,000+ users running it today. It's open source, with 1,650+ stars on GitHub and contributors from across the world. It has been cited in peer-reviewed clinical research on offline mobile edge AI. Every decision named above - model choice, platform, server boundary, compliance posture - we have made before, at scale, for real deployments.
The engagement is four sprints. Each sprint is fixed-price. Each sprint has a named deliverable your team can put on a roadmap.
Discovery (Week 1, $5K): We resolve the four decisions - model, platform, server boundary, compliance posture. Deliverable: a 1-page architecture doc your CTO can take to the board and your Privacy Officer can take to Legal.
Integration (Weeks 2-3, $5K-$10K): We ship the on-device model into your app behind a feature flag. Deliverable: a working build your QA team can test against real workflows.
Optimization (Weeks 4-5, $5K-$10K): We hit the performance and compliance targets from the discovery doc. Deliverable: benchmarks signed off by your team.
Production hardening (Week 6, $5K): Edge cases, OS version coverage, app store and compliance review readiness. Deliverable: shippable build.
4-6 weeks total. $20K-$30K total. Money back if we don't hit the benchmarks. We have not had to refund.
"Retention improved from 42% to 76% at 3 months. AI recommendations rated 'highly relevant' by 87% of users." - Jackson Reed, Owner, Vita Sync Health
Worth 30 minutes? We'll walk you through what your version of the four decisions looks like, what a realistic scope and timeline would be for your app, and what your compliance posture and on-device target mean in practice. You'll leave with enough to run a planning meeting next week. No pitch deck. If we're not the right team, we'll tell you who is.
