What is Reflexio?

The moat for AI agents isn't the model — it's what your agent learns from every interaction it handles.

Reflexio is a self-improvement platform for AI agents. It turns every conversation your AI agent has into a learning opportunity — automatically extracting user preferences and behavioral playbooks so your agent continuously improves itself without manual tuning.

    D --> E[Playbook Aggregation]
    B --> F[Success Evaluation]

Publish conversations from your agent, and Reflexio closes the self-improvement loop:

• Never Repeat the Same Mistake: Transforms user corrections and interaction signals into improved decision-making processes — so agents adapt their behavior and avoid repeating the same mistakes.
• Lock In What Works: Persists successful strategies and workflows so your agent reuses proven paths instead of starting from scratch.
• Correct in Real Time: Retrieves personalization and operational signals to fix agent behavior live — no retraining required.
• Learn from Human Experts: Publish expert-provided ideal responses alongside agent responses — Reflexio automatically extracts actionable playbooks from the differences.
• Personal & Global Improvements: Separates individual user preferences from system-wide agent improvements.
• AI First Self-Optimization: Agents autonomously reflect, learn, and improve — less human-in-the-loop, more compounding gains.

For developers: See developer.md for project structure, environment setup, testing, and coding guidelines.

Demo

Quick Start

Prerequisites

Tool	Description
uv	Python package manager
Node.js >= 18	Frontend runtime

Setup

# 1. Clone and configure
git clone https://github.com/reflexio-ai/reflexio.git
cd reflexio
cp .env.example .env          # Set at least one LLM API key (OpenAI, Anthropic, etc.)

# 2. Install dependencies
uv sync                                   # Python (includes workspace packages)
npm --prefix docs install                  # API docs

# 3. Start services (--storage sqlite is the default)
uv run reflexio services start                    # API (8081), Docs (8082), SQLite storage
uv run reflexio services stop                     # Stop all services

Alternative: python -m reflexio.cli services start or ./run_services.sh

Once running, open http://localhost:8082 to interactively browse and try out the API.

Try it in 30 seconds (CLI)

Reflexio ships a first-class CLI — the fastest way to see the loop end-to-end with no code. Publish a real multi-turn conversation where the user corrects the agent (that's the signal Reflexio learns from), then search for what was extracted:

uv run reflexio publish --user-id alice --wait --data '{
  "interactions": [
    {"role": "user",      "content": "Deploy the new service."},
    {"role": "assistant", "content": "Starting deployment to us-east-1..."},
    {"role": "user",      "content": "Wait — we never deploy production to us-east-1. Always use us-west-2."},
    {"role": "assistant", "content": "Understood. Switching to us-west-2."}
  ]
}'

# Search the extracted profiles and playbooks
uv run reflexio search "deployment region"

One conversation, two artifacts: a user profile (production region is us-west-2) and an agent playbook (confirm region before deploying). See the CLI reference for all input modes (inline JSON, --file, --stdin) and the full command list.

Integrate with the Python SDK

import reflexio

client = reflexio.ReflexioClient(
    url_endpoint="http://localhost:8081/"
)

# Publish a multi-turn conversation where the user corrects the agent —
# Reflexio extracts a profile ("prod region = us-west-2") and a playbook
# ("confirm region before deploying").
client.publish_interaction(
    request_id="req-001",
    user_id="alice",
    interactions=[
        reflexio.Interaction(role="user",      content="Deploy the new service."),
        reflexio.Interaction(role="assistant", content="Starting deployment to us-east-1..."),
        reflexio.Interaction(role="user",      content="Wait — we never deploy production to us-east-1. Always use us-west-2."),
        reflexio.Interaction(role="assistant", content="Understood. Switching to us-west-2."),
    ],
)

Reflexio will automatically generate profiles and extract playbooks in the background.

Features

Profile Generation

• Extracts behavioral profiles from conversations using configurable extractors
• Supports versioning (current → pending → archived) with upgrade/downgrade workflows
• Multiple extractors run in parallel with independent windows and strides

Read more about user profiles →

Playbook Extraction & Aggregation

• Extracts playbooks from user behavior patterns
• Clusters similar entries and aggregates with LLM (with change detection to skip unchanged clusters)
• Approval workflow: review and approve/reject agent playbooks

Read more about agent playbooks →

Expert Learning

• Publish human-expert ideal responses alongside agent responses via the expert_content field
• Reflexio automatically compares agent vs. expert responses, focusing on substantive differences (missing info, incorrect approach, reasoning gaps) while ignoring stylistic ones
• Generates actionable playbooks as trigger/instruction/pitfall SOPs that teach the agent what to do differently

Read more about interactions & expert content →

Agent Success Evaluation

• Session-level evaluation triggered automatically (10 min after last request)
• Shadow comparison mode: A/B test regular vs shadow agent responses
• Tool usage analysis for blocking issue detection

Read more about evaluation →

Search & Retrieval

• Hybrid search (vector + full-text) across profiles and playbooks
• LLM-powered query rewriting for improved recall
• Unified search across all entity types in parallel
• Fast at scale: unified search across ~3,000 indexed rows (profile + user playbook + agent playbook, ~1,000 rows each, queried in parallel) runs at ~57 ms p50 / ~73 ms p95 — measured service-layer with local SQLite on an Apple Silicon MacBook, 30 trials × 20 fixed queries. See the full benchmark report or reproduce with reflexio.benchmarks.retrieval_latency.

Multi-Provider LLM Support

• OpenAI, Anthropic, Google Gemini, OpenRouter, Azure, MiniMax, and custom endpoints
• Powered by LiteLLM — configure your preferred provider via API keys or custom endpoints

SDK Usage

For detailed API documentation, see the full API reference.

Install the client:

pip install reflexio-client

Basic usage

import reflexio

client = reflexio.ReflexioClient(
    url_endpoint="http://localhost:8081/"
)

# Publish interactions
await client.publish_interaction(
    request_id="req-001",
    user_id="user-123",
    interactions=[...],
    agent_version="v1",       # optional: track agent versions
    session_id="session-abc", # optional: group requests into sessions
)

# Search profiles
profiles = await client.search_profiles(
    reflexio.SearchUserProfileRequest(query="deployment region preference")
)

# Search agent playbooks
playbooks = await client.get_agent_playbooks(
    reflexio.GetAgentPlaybooksRequest(agent_version="v1")
)

Configuration

# Update org configuration
await client.set_config(reflexio.SetConfigRequest(
    config=reflexio.Config(
        api_key_config=reflexio.APIKeyConfig(openai="sk-..."),
        profile_extractor_configs=[...],
        playbook_configs=[reflexio.PlaybookConfig(...)],
    )
))
