AI providers

Connect OpenAI, Anthropic, Google keys. Switch models per prompt. Keys encrypted server-side — never exposed to browser.

Try the model picker

Select a provider, add a (fake) API key, pick a model, and simulate a prompt run.

Supported providers

Setup flow

1. Get API keys from each provider’s dashboard
2. Open PromptAura → Settings → AI Providers
3. Click “Add Key” for each provider
4. Paste key → encrypted and stored server-side
5. Select default model per provider

Switching models per prompt

When editing a session, the model selector (top-right) shows all your configured models:

Model: ▼ GPT-4o (OpenAI) ▼
       ├─ GPT-4o
       ├─ GPT-4o-mini
       ├─ GPT-4-turbo
       ├─ o1-preview
       ├─ Claude 3.5 Sonnet (Anthropic)
       ├─ Claude 3 Opus (Anthropic)
       ├─ Claude 3 Haiku (Anthropic)
       ├─ Gemini 1.5 Pro (Google)
       └─ Gemini 1.5 Flash (Google)

Pick one → that prompt uses that model. Your choice saves with the session.

Why multi-model?

BYOK (Bring Your Own Keys) architecture

┌─────────────┐     HTTPS      ┌──────────────┐     Encrypted     ┌─────────────┐
│  Your Browser  ─────────────→  │  PromptAura   ───────────────→  │  AI Provider │
│               │  (no keys)     │  Server       │  (decrypt key)    │  (OpenAI)    │
└─────────────┘                └──────────────┘                   └─────────────┘

1. Browser sends: POST /api/v1/sessions/:id/run { model: "gpt-4o", variables }
2. Server decrypts your OpenAI key (AES-256 at rest)
3. Server calls OpenAI API with your key
4. Server streams response back to browser

Your browser never sees the API key. This is the key security advantage.

Rate limits & costs

PromptAura shows estimated cost before you run (based on input tokens + model pricing).

API access

Multi-model works via REST API:

curl -X POST https://prompt-aura.ppai.web.id/api/v1/sessions/:id/run \
  -H "Authorization: Bearer pa_xxx..." \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-3-5-sonnet-20241022", "variables": {"topic": "API design"}}'

See API Reference → Run Session for full schema.
