05

Looks good

Dark mode, light mode, resizable panes. No ugly crap.

07

Fast

09

Drag & drop

10

Tracker blocker

11

Local AI

Summarize emails and get reply suggestions via Ollama. Runs on your machine. No cloud, no API keys.

12

Smart replies

AI suggests three reply tones — professional, friendly, concise. Pick one and go.

I don't store your data.

I don't have a server — well, I do for this website. Premium and Team will need one eventually, but even then: your emails stay local. I don't want your data. That's it.

Local AI. Your questions.

Prudii uses Ollama to run AI models on your machine. Here's what you need to know.

Q What is Ollama and why do I need it?

Ollama is a free, open-source tool that lets you run large language models locally on your computer. Prudii uses it as the AI backend — instead of sending your emails to OpenAI or Google, everything stays on your machine. You install Ollama once, download a model, and Prudii talks to it on localhost. No API keys, no subscriptions, no cloud.

Q Is my email data sent anywhere?

No. Ollama runs entirely on your machine. When Prudii asks for a summary or reply suggestion, it sends the email text to localhost:11434 — that's your own computer. Nothing leaves your network.

Q Which models work best?

For email summaries and reply suggestions, 7B–8B parameter models hit the sweet spot between speed and quality:

  • llama3.2 — Fast, solid all-rounder. Good starting point.
  • mistral — Great at following instructions, good for replies.
  • gemma2 — Compact and fast, decent summaries.

Install one with ollama pull llama3.2 and you're good to go. Bigger models (13B+) give better results but need more RAM and a decent GPU.

Q Do I need a GPU?

Not strictly, but it helps a lot. Ollama can run on CPU only, but responses will be slow (30–60 seconds for a summary). With a GPU that has 6+ GB VRAM (like an RTX 3060 or better), you'll get responses in 2–5 seconds. 16 GB RAM minimum is recommended either way.

Q How do I set it up?
  1. Download and install Ollama from ollama.com
  2. Open a terminal and run: ollama pull llama3.2
  3. Make sure Ollama is running (it starts automatically on install)
  4. In Prudii, go to Settings → AI and enable it
  5. Click "Test Connection" — your models will show up
  6. Select a model and you're done
Q What can the AI actually do?

Right now, two things:

  • Summarize emails — Get a quick summary of long emails or entire threads. Click the sparkle icon on any email.
  • Reply suggestions — The AI suggests three replies in different tones: professional, friendly, and concise. Pick one, edit it, send it.

Both features are available as a Premium feature. The AI is entirely optional — Prudii works perfectly fine without it.

// why "Prudii"?

Prudii is Mando'a for shadow. It's from the Mandalorian language. Just you and your inbox, in the shadows.

$ prudii --about

I'm basically a huge nerd who spends way too much time at the PC with energy drinks and good vibes. This project started at home just for me, but then I figured — why not let you all in on it too. Would love your support!
