AI accountability partner for ADHD-friendly planning and habits
Chat with Pia to co-create a daily plan, get one question each night about whether today counted, and receive lighter versions of your day when you slip.
A single-next-step view paired with a timer that reduces the friction of getting started on a task.
Habits that bend rather than break: a missed day never resets the progress you have stacked up.
Pia is reachable in Telegram and Discord, and Pro connects it to Claude or ChatGPT so your assistant works with real tasks, habits and schedules.

Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
