On-Device Affective AI & Developer SaaS Platform

Proactive Mental Wellness Agents, Grounded in Real-World Context.

BestAgent AI silently observes behavioral patterns and ambient physical-world signals directly on-device, models subtle psychological shifts before depressive episodes escalate, and gives developers a customizable Agent SDK to deliver timely, empathetic emotional support.

✓ Local-First Zero-Knowledge Telemetry ✓ Sub-150ms Edge Inference ✓ TypeScript & Python Agent SDK
Core Capabilities

From Passive Physical Context to Timely Emotional Intervention

Traditional wellness chatbots wait until a user types "I feel overwhelmed." BestAgent AI bridges ambient real-world context with customizable developer agents to intervene gently and early.

Zero-Footprint On-Device Capture

Passively aggregates step cadence, sleep-wake rhythm, ambient light transitions, and interaction velocity locally on the user's phone or wearable. Raw audio, video, and GPS coordinates never leave the device.

Early Affective Drift Modeling

Our temporal behavioral models identify subtle signatures of emotional fatigue, social withdrawal, and depressive escalation days before acute distress—delivering calm, evidence-informed mood regulation prompts.

Customizable AI Agent SaaS

Purpose-built for digital health, companion apps, and employee wellness teams. Customize agent personas, intervention policies, safety guardrails, and webhook triggers through a clean REST & SDK layer.

Privacy-Preserving Architecture

Edge-First Signal Processing, Cloud-Native Agent Orchestration

Every deployment separates sensitive physical telemetry from cloud reasoning using compact, encrypted state embeddings.

01 · Edge Capture

Ambient & Behavioral Fusion

Lightweight iOS, Android, and desktop listeners capture circadian, motion, and usage cadence in the background (<1.5% daily battery).

02 · Local Inference

Encrypted State Vector

On-device TFLite/CoreML models convert raw signals into anonymized affective risk scores without transmitting personal logs.

03 · Agent SaaS

Policy & Persona Engine

BestAgent Cloud evaluates developer-defined thresholds, longitudinal memory, and clinical safety guardrails in real time.

04 · Intervention

Timely Empathetic Nudge

Dispatches tailored CBT micro-exercises, breathing cues, or supportive check-ins directly through your app's agent UI.

Developer Platform

Customize Every Care Agent in Minutes

Embed emotion-aware context into your existing LLM pipeline or launch a standalone mental-wellness agent using our managed SaaS SDK.

Custom Persona & Tone Controls Tune empathy cadence, communication warmth, and CBT/mindfulness intervention libraries per user cohort.
Deterministic Safety Guardrails Built-in escalation hooks route high-risk distress patterns to verified human care teams or local crisis hotlines.
Real-Time Webhooks & Longitudinal Memory Subscribe to mood-shift events across sessions while keeping raw behavioral telemetry scoped to edge storage.
import { BestAgentClient } from "@bestagent/sdk";

const client = new BestAgentClient({
  apiKey: process.env.BESTAGENT_API_KEY,
  region: "us-central1",
});

// Subscribe to privacy-preserving edge affective vectors
client.onStateShift(async (event) => {
  if (event.riskTier === "moderate_strain") {
    const reply = await client.agents.composeIntervention({
      agentId: "calm-companion-v2",
      stateVector: event.encryptedVector,
      modality: "push_checkin",
      guardrails: ["non_clinical_support", "cbt_reframing"],
    });
    await notifyUserApp(event.userId, reply.message);
  }
});
