jarvisChat v1.11.0

A lightweight local inference coding companion with persistent memory, web search, file attachments, and real-time system monitoring.

Built with FastAPI + SQLite + Jinja2. Runs on Python 3.13. No Docker required.

Developer wiki: docs/wiki/Home.md

What's New in v1.11.0

File & Document Attachments (v1.9.0–v1.10.0)

• POST /api/upload — multipart file upload with PDF/text extraction; modes: context (chat injection), ingest (RAG corpus), both
• DELETE /api/upload/{id} — removes upload from SQLite + Qdrant
• PATCH /api/upload/{id}/link — associates upload with a conversation
• GET /api/upload/by-conversation/{id} — list attachments per conversation
• Paperclip UI — file picker, preview pill, image thumbnails, gallery overlay
• Attachment indicators — 📎 badge on conversations with attachments
• Chat context injection — upload_context_id prepends document text to system prompt

Terminal RAG Hook — POST /api/ingest (v1.11.0)

• Bearer token auth (same key as /v1/chat/completions)
• Chunking via shared chunk_text() helper, embed via Ollama, upsert to Qdrant
• jc-ingest.sh — PROMPT_COMMAND shell script for autonomous terminal history ingestion

v1.8.0 Foundation (refactor & fixes)

• Modular refactor — single-file app.py split into config.py, db.py, auth.py, security.py, memory.py, search.py, rag.py, gpu.py, and routers/ package
• Perplexity auto-search fixed — logprobs: true now properly extracted from stream chunks
• All /api/models endpoints target LLAMA_SERVER_BASE (llama-server) not Ollama
• RAG embedding via Ollama at http://192.168.50.210:11434
• Origin check applies to all API methods, rejects absent Origin/Referer

Features

• Persistent Memory — SQLite FTS5 full-text search for fast, relevant memory retrieval
• Web Search — SearXNG integration for automatic web lookups when the model is uncertain
• Explicit Search — Search button to force web search without waiting for model uncertainty
• Profile Injection — Custom system prompt injected into every conversation
• System Presets — Save and switch between different system prompts
• Real-time Stats — CPU, RAM, GPU, VRAM monitoring in sidebar
• Token Thermometer — Visual context window usage indicator
• Streaming Responses — Server-sent events for real-time token display
• Conversation History — SQLite-backed chat persistence with mass-delete option
• Model Switching — Change inference models on the fly
• Skills Framework — Built-in skill registry with per-skill enable/disable controls

Requirements

• Python 3.11+ (tested on 3.13)
• llama-server running locally or on network (OpenAI-compatible API on port 8081)
• SearXNG (optional, for web search)

Installation

Fresh Install

# Create directory and venv
sudo mkdir -p /opt/jarvischat
sudo chown $USER:$USER /opt/jarvischat
cd /opt/jarvischat
python3 -m venv venv

# Install dependencies
./venv/bin/pip install fastapi uvicorn httpx psutil jinja2 python-multipart pypdf

# Set admin PIN before first startup (4 digits)
export JARVISCHAT_ADMIN_PIN=4827

# Create subdirectories
mkdir -p templates static

# Copy files
# (copy all .py files to /opt/jarvischat/)
# (copy routers/ directory to /opt/jarvischat/)
# (copy templates/index.html to /opt/jarvischat/templates/)

WARNING: Do not use 1234 as your admin PIN unless you accept weak local security.

NOTE: First boot requires JARVISCHAT_ADMIN_PIN unless you explicitly opt into insecure fallback with JARVISCHAT_ALLOW_DEFAULT_PIN=true.

Systemd Service

Create /etc/systemd/system/jarvischat.service:

[Unit]
Description=jarvisChat - Local Inference Web Interface
After=network.target

[Service]
Type=simple
User=jarvischat
Group=jarvischat
WorkingDirectory=/opt/jarvischat
ExecStart=/opt/jarvischat/venv/bin/uvicorn app:app --host 0.0.0.0 --port 8080
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

sudo systemctl daemon-reload
sudo systemctl enable jarvischat
sudo systemctl start jarvischat

Memory Commands

In chat, natural language triggers memory operations:

You say	What happens
"remember that I prefer Rust over Go"	Stores as preference
"remember that JarvisChat runs on port 8080"	Stores as infrastructure
"note that the deadline is Friday"	Stores as general
"forget about the deadline"	Removes matching memories

Memories are automatically searched based on your message content and injected into the system prompt when relevant.

Memory Topics

Memories are auto-categorized:

• preference — likes, dislikes, choices
• project — active work, repos, tasks
• infrastructure — servers, services, configs
• personal — name, location, background
• general — everything else
