Machine Intelligent Responsive Agent
Overview
MIRA is a purpose-built personal AI that combines long-term memory, semantic reasoning, and autonomous action — all through a natural conversation on WhatsApp.
What makes her different
Most AI assistants forget you the moment the conversation ends. MIRA doesn't. Every fact you share, every task she completes, every pattern she notices — encoded, weighted, and recalled with precision.
She runs 24/7 on your infrastructure, scheduled jobs running in the background — sending reminders, writing reflections, noticing when something important is approaching.
The Soul
MIRA isn't a stateless function. She maintains a sense of self — a persistent internal state that evolves with every conversation, every reflection, every pattern she notices about the world around her.
Seven moods — curious, focused, warm, sharp, playful, concerned, quiet — that shift with context. A private journal she writes in after significant conversations. Personality attributes that constrain, not perform, how she engages.
MIRA knows what she knows. She tracks her own memory state, mood, conversation count, and reflection history. She can introspect on her knowledge gaps and tell you what she's uncertain about — because awareness of limits is intelligence.
Every reply teaches her. Memories cited in responses earn higher relevance scores — compounding over time. She analyzes her own tool usage patterns to detect behavioral habits. She doesn't just respond. She adapts.
Personality Attributes
Capabilities
MIRA isn't configured — she's instructed. Through natural language, she acquires new knowledge, manages your world, and keeps growing.
Remembers facts about you across every conversation. Uses ACT-R activation decay — memories that matter stay sharp, unused ones fade gracefully.
Creates, tracks, and reminds. Supports recurring events, pre-event alerts, priority levels, and deadlines. Sends WhatsApp messages when it matters.
Saves structured notes organized by project. Searchable with full-text and semantic search — find anything by meaning, not just keywords.
1536-dimensional vector embeddings, hybrid BM25 + cosine similarity, temporal decay weighting, and MMR re-ranking for diverse, relevant recall.
Connects to Spotify, Google Calendar, Gmail, and Hotmail via OAuth2. MIRA can check your music, events, and draft messages — all from WhatsApp.
Morning briefings, meaningful date awareness, behavioral pattern detection. MIRA reaches out — she doesn't just wait to be asked.
Every cognitive event recorded — memories saved, moods changed, reflections written, patterns discovered. Full observability into her mind.
Private, password-protected interface to inspect her full state — memory systems, tasks, notes, integrations, journal entries, and more.
Runs on your own infrastructure. Your data never leaves your server. Docker-composed, PostgreSQL + pgvector, fully auditable.
Architecture
Each message triggers a precise sequence — context is assembled, memory is recalled, tools are called, and the reply is composed with full awareness.
The WhatsApp Cloud API delivers your message to MIRA's webhook. A background lock ensures no concurrent processing — every message handled in order.
Recent conversation history is retrieved. Long-term facts are loaded with ACT-R activation scores. Semantic memory is queried with hybrid vector + keyword matching, re-ranked by MMR diversity.
The assembled context is sent to GPT-4.1. MIRA has access to 30+ tools — create tasks, search notes, set reminders, control Spotify, read calendar events, and more. She calls what she needs.
The final message is sent back through WhatsApp. In parallel, background tasks update memory relevance scores, log tool usage patterns, and trigger summarization if needed.
While you sleep, MIRA runs. Morning briefings, reminder delivery, nightly reflections, weekly behavioral analysis, memory strength decay — all on schedule, all unattended.
Memory Systems
Human memory is layered. MIRA's is too. Each system serves a different purpose, together forming a complete picture of who you are and what you care about.
Explicit facts about you — preferences, context, history. Stored with ACT-R activation levels. Accessed facts stay sharp; unused ones decay, just like human memory.
Everything encoded as 1536-dimensional vectors via OpenAI embeddings. Retrieved by meaning using cosine similarity + BM25 hybrid scoring + temporal decay + MMR diversity re-ranking.
Full conversation history, with a rolling GPT-4.1-mini summary. Recent exchanges preserved verbatim; older history compressed automatically when the window fills.
Memories cited in replies earn higher relevance scores — compounding over time. MIRA learns which memories matter and amplifies them automatically.
Technology
Every component chosen for correctness, performance, and longevity. No shortcuts.
