AI Writer

About

AI Writer turns your rough email drafts into polished, professional messages — without leaving Gmail or Outlook.
Select any text, right-click, choose a prompt, and watch AI rewrite it in your tone, language, and style. No copy-pasting to ChatGPT. No context switching. Just better emails, faster.

✦ How it works

Open Gmail or Outlook
Select the text you want to improve
Right-click → AI Writer → choose a prompt
Review the result, click Replace — done


✦ Key Features
Works where you work
Seamlessly integrated into Gmail and Outlook (web). No new tabs, no separate apps.
Your choice of AI

Connect your own API key from any major AI provider — 
including free options like Gemini and OpenRouter that 
require no credit card.

Up to 7 custom prompts
Create, name, and reorder your own AI prompts. Drag to rearrange. Each prompt appears in your right-click menu instantly.
Prompt Wizard — build better prompts without writing code
Not sure how to write an AI prompt? The built-in wizard guides you step by step:

Choose a category: translate, paraphrase, reply to email, business negotiation, B2B message, or custom
Select an influence framework and more
Set tone: formal, informal, assertive, empathetic — or write your own
Anti-AI hygiene settings: automatically removes em-dashes, markdown, filler phrases, and other telltale AI patterns
Live XML prompt preview with character count and quality indicator
One-click optimization: AI shortens your prompt for faster, cheaper responses

Appointment scheduling built in
For email replies that include a meeting or appointment — pick date, time, duration, and service type directly in a calendar picker. AI includes all details naturally in the reply.
Built-in humanizer
Every prompt includes a humanizer layer that makes AI output sound like a real person wrote it — no em-dashes, no "Certainly!", no robotic closings, no rule-of-three marketing speak.
Model benchmark tab
Compare response times and token usage across all your connected AI models. See which model is fastest for your workflow and export results for further analysis.
Provider model testing
One click tests all models for a given API key — confirms which models are working, shows response time, and logs results to the debug log.
Debug log
Every API call, error, and event is logged with timestamps and elapsed time. One-click copy to paste into any AI chat for instant troubleshooting.
Dark mode
Full light / auto / dark mode support. Follows your system preference or set it manually.
Bilingual UI
Switch between Slovenian and English with one click.

✦ Privacy & Security

Your API keys never leave your device. Stored in Chrome's local extension storage — not synced to the cloud, not sent to any server.
Your emails are never stored. Text goes directly from your browser to the AI provider you chose — AI Writer never sees or stores the content.
No tracking, no analytics, no ads. Ever.
Content scripts run in an isolated environment — no Gmail or Outlook page scripts can access your keys or settings.
