AI Setup Guide

DrawLint offers three ways to power your AI design reviews:

• Unlimited reviews — no monthly cap, practice as much as you want
• Free option available — Gemini AI costs nothing, just a Google API key
• Your own models — choose GPT, Claude, or any model you've deployed (Azure)
• Zero cost on DrawLint — you only pay your own API usage (or nothing with Gemini free tier)

Your API key is stored only in your browser's localStorage. When you submit a design for review, your credentials are sent over HTTPS to our server, which forwards the request to Azure OpenAI on your behalf — then immediately discards them.

Key guarantees:

• We never log your API key, endpoint, or deployment name
• We never store your credentials in our database or on disk
• Your key is used only for the duration of that single API call, then discarded from memory
• All communication is encrypted over HTTPS

The fastest way to get unlimited AI reviews — takes about 30 seconds.

1. 1

   Get a free Gemini API key

   Go to Google AI Studio and create an API key. It's free and takes about 30 seconds.

2. 2

   Open Settings → Select Gemini AI

   In DrawLint, open Settings and click the "Gemini AI" card.

3. 3

   Paste your key → Test → Save

   Enter your API key, click "Test Connection" to verify it works, then click Save.

For power users who want full control — takes about 10-15 minutes.

1. 1

   Create an Azure OpenAI resource

   Go to the Azure Portal and create an Azure OpenAI Service resource.

2. 2

   Deploy a model

   Deploy a model such as gpt-4o or gpt-5.4. Note the deployment name.

3. 3

   Copy credentials from Azure Portal

   Under "Keys and Endpoint", copy your API key, endpoint URL, and deployment name.

4. 4

   Open Settings → Select "Azure OpenAI"

   In DrawLint, open Settings and click the "Azure OpenAI" card.

5. 5

   Paste credentials → Test → Save

   Enter all three fields, click "Test Connection" to verify, then click Save.

• Stored only in your browser — credentials live in localStorage, sandboxed to your browser session
• Never logged or persisted — our server processes your key in-memory for a single request, then discards it. No database, no logs, no disk writes.
• Clear key button — instantly wipe your credentials with one click in Settings
• HTTPS everywhere — all communication between your browser, our server, and Azure is encrypted in transit
• Publicly available — our codebase is public on GitHub — you can verify exactly how keys are handled
