AI assistants and search decision

Saner.AI

A capable developer can implement a useful ADHD-focused assistant (chat + tasks + calendar + notifications) within a week and maintain it; the hosted product's polish, user base, and any proprietary models would be lost.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.

What a replacement has to do

  • A minimal replacement provides a conversational assistant that stores and surfaces short-term tasks/reminders, syncs or imports calendar events, accepts plain-text or web input, and sends scheduled notifications.

What it still won’t have

  • Polished UX and mobile app polish
  • Any proprietary models, training data, or closed-source optimizations
  • Existing user base, analytics, and product support
  • Platform-level reliability and SLAs

What remains hard

  • Product polish and ongoing maintenance

Runnable build prompt

Not run yet
Build a minimal AI personal assistant web app using Next.js (React) frontend, FastAPI backend, and Postgres. Core features: chat interface that sends messages to an LLM (configurable OpenAI-compatible API), CRUD task/reminder storage, one-way Google Calendar import (OAuth and event import), background scheduler to deliver notifications via an email provider (SendGrid) and SMS (Twilio), and basic auth (magic-link). Out of scope: native mobile apps, advanced agent orchestration, training custom models, and multi-tenant admin UI. Include error handling for network, API quota, and scheduler failures, automated unit tests for backend endpoints, and deployment scripts (Dockerfiles and a simple Terraform or Docker Compose setup).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
