Now with calendar and tasks.

Email alone wasn't enough. Prudii 1.7 handles your appointments and to-dos too, and long threads finally read like a chat. Still local. Still free.

A calendar right next to your inbox.

Month, week, work week, day and agenda. Drag to create, move and resize events. Recurring events and reminders included.

  • Turn any email into an event
  • Subscribe to calendar links (webcal, Google, iCloud, Outlook)
  • Import Google Calendar exports, even as a ZIP
  • Tasks that are due show up between your events

Tasks for everything that's more than an email.

Board or list, your call. Type “tomorrow 9:00” and the due date is set. Drag an email onto a task and it stays linked.

  • Checklists, notes and files per task
  • Reminders with a done button
  • Link emails by drag and drop or right-click

Long threads read like a chat.

Your messages on the right, everyone else's on the left. The quoted history that piles up under every reply gets folded away.

  • Switch between classic and chat under Conversation view
  • Folded history is one click away

And everything else since summer.

What it does.

It's an email client. It does email. Here's the short version.

01

Everything local

Your emails stay on your machine. Not in the cloud. Period.

02

Full-text search

Searches all your emails instantly. Offline.

03

Encrypted passwords

Locked in your system's keychain. Other apps on your machine can't touch them.

04

Multiple accounts

Gmail, Outlook, GMX, whatever. All in one inbox.

05

Looks good

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

06

7 languages

English, Deutsch, Español, Français, Português, 中文, Русский.

07

Fast

Rust + Tauri. Starts in seconds.

08

Backup & restore

Mail, tasks and calendars in one ZIP. Passwords too if you want, encrypted with your passphrase.

09

Drag & drop

Move emails between folders. Attach files by dropping.

10

Tracker blocker

Detects and blocks tracking pixels, hidden images, and 70+ known tracker domains. Automatically.

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.

13

Out of office

Set it right in Prudii. Your mail server replies, even when the app is closed. If your provider supports it.

14

Signature editor

Edit your signature right in the preview. Logos and formatting stay where they are.

15

Feels native

Notifications with an archive button, swipe to archive, drag attachments onto your desktop. Uses your system's accent color.

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.

✓ No server. Everything local.
✓ No tracking. No telemetry.
✓ Passwords locked in your system keychain.
✓ External images blocked.
✓ Tracking pixels detected & stripped.
✓ AI runs locally via Ollama. No cloud.
✓ Direct IMAP/SMTP. No proxy.

I don't want your data. I just wanted a good email client.

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.

Premium & Team

Premium brings AI, rules, and power features for individuals. Team adds shared inboxes, templates, and admin tools for your organization. The free version isn't going anywhere though — this isn't one of those "free until you need it" things.

// 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!

// built with Rust, Tauri, React, and too many energy drinks.
