Features

A tour of what NilaMind does. Everything here runs on-device.

Talk to Nila

  • Text or voice chat with Nila, a warm companion grounded in real therapy approaches who listens first and offers one small, concrete thing only when it helps.
  • Voice-first input — tap to talk is primary; typing is one tap away (ModeScreen.tsx, voice.ts).
  • Spoken replies — Nila's replies can be read aloud by default (on-device TTS).
  • Hands-free call mode — a phone-call-style conversation.
  • "Hey Nila" wake word — an on-device Vosk wake-word path (wakeWord.ts, wakePrefs.ts).

Check-ins & mood

  • Opening check-in — a light tap-based check-in when you open the app (NilaCheckIn, checkin.ts).
  • Mood tracking over time (moodHistory.ts), surfaced in the dashboard and insights.

Insight (your own trajectory, not a benchmark)

  • Dashboard & insights — mood history, patterns, streaks (DashboardScreen, dashboardInsights.ts, patternInsights.ts, streaks.ts).
  • Inflection awareness — Nila can gently notice and name a real shift in your own trajectory (off by default, at most once a day, §9-safe) using on-device, valence-aware trend detection (nilaInflection.ts, inflectionPrefs.ts).
  • Sleep signal — optional sleep input (and a Health Connect path) feeding a manic-prodrome short-sleep detector (sleepInsight.ts, healthConnect.ts).

Evidence-based skills

A library of short, research-based skills you can open and follow (SkillsLibraryScreen, skillsLibrary.ts, retrieved contextually by skillRetrieval.ts):

  • Thought Record (CBT) — ThoughtRecordScreen
  • Diary Card (DBT) — DiaryCardScreen
  • Behavioural Activation — behaviouralActivation.ts
  • Values → Action (ACT) — ValuesToActionScreen, values.ts
  • Self-Compassion (CFT)
  • Wind-Down (CBT-I, for sleep) — WindDownScreen, windDown.ts
  • Grounding library — GroundingLibraryScreen
  • Psychoeducation — LearnScreen.tsx, psychoed.ts
  • Safety Plan — SafetyPlanScreen

Staying connected to real people

  • "Letter to my unwell self" pact — write, while well, what you want to hear when you're not; it can be surfaced back to you later (PactScreen, pact.ts, pactNotice.ts).
  • Notice → letter → human handoff — a signal can lead to your own letter and a gentle nudge toward a trusted person.
  • Reach-out bridge — a guided way to reach a trusted person (ReachOutScreen, reachOut.ts).
  • Dependency guard — if you're leaning on Nila too heavily, she nudges you toward real human connection rather than becoming a replacement for it.

Memory you control

  • Compounding memory — Nila can hold a couple of stable facts and what you're working through, only with your consent, and surface them like a friend who remembers (nilaMemory.ts, nilaInsights.ts).
  • "What Nila remembers" — view, edit, and delete all of it (NilaMemoryScreen).

Other

  • Agent console (not yet shipped) — a proposed surface for the more agent-like "notice and show up" behaviours. The phone-usage / "notice and show up" path currently ships dark (phoneEnabled is hardcoded false).
  • Assessments — optional structured check-ins (AssessmentScreen, assessments.ts).
  • Identity & lock — BIP39 on-device identity (IdentityOnboarding) with an optional biometric gate on sensitive actions (BiometricGateHost).
  • Theming — light/dark/system.

Every feature above is designed around the same constraint: it should help, on-device, without ever harvesting your data. Where a feature could touch safety, the §9 layer runs in front of it.
