Extract, analyze, and automate Outlook Classic emails on Windows, with optional LLM-powered plugins.

Mailslide

A Windows + Outlook Classic automation tool for turning repetitive email work into reliable workflows. Use configurable jobs and optional LLM plugins to classify, route, summarize, and structure email processing.

Warning: AI reads your emails. Make sure emails processed by AI do not contain personal privacy data or business confidential information, or use a local model for processing.

Disclaimer: This project is provided as-is and does not guarantee the security of data processed by third-party or local AI models. The project authors are not liable for any data breach, confidential information leakage, or related damages resulting from user inputs or model services. Users are responsible for risk assessment and compliance with organizational policies and applicable laws.

Why Mailslide

• Standardize Outlook processing with repeatable job-based workflows.
• Go beyond classification: move folders, create appointments, export JSON/CSV/Excel.
• Keep deployment flexible: OpenAI-compatible APIs or local models (Ollama, llama.cpp).
• Friendly for non-developers: initialize and edit configs directly in the TUI.

Typical use cases

• Operations and assistants: triage meeting requests, alerts, and routine inbox traffic.
• PMs and sales: convert email streams into trackable events and summaries.
• Engineering and support: auto-tag and prioritize incoming threads.

30-second start (End users)

uv tool install mailslide
mailslide-tui

After first launch, open About and click Initialize Config.

Upgrade:

uv tool upgrade mailslide

When a release changes config schema, the app auto-migrates config/config.yaml on load and writes a timestamped backup (for example: config.yaml.bak.20260327_153000).

30-second start (Developers / source mode)

uv sync
uv run app.py

Then in TUI:

1. Open About and click Initialize Config.
2. Open Configuration and set Jobs / LLM / Plugins.
3. Return to Home and run a job (Preserve RE/FW is ON by default and can be toggled on Home).

Results Preview

• Home run and logs: show one job run with processing summary (includes quick Preserve RE/FW toggle, default ON)
• Configuration forms: show Jobs / LLM / Plugins setup screens
• Plugin editor: show Prompt Profiles and validate/save flow
