Gravity Connect — OpenAI Integration

Gravity Connect (OpenAI Connection) integrates Gravity Forms directly with OpenAI for AI text generation, image creation, voice transcription, and automated entry processing. Part of the Gravity Wiz ecosystem, installed via Spellbook.

When to use

• Setting up AI text generation inside a form (before submission)
• Configuring post-submission AI processing (email drafting, classification, tagging)
• Building AI-powered form moderation
• Generating images with GPT Image from form data
• Voice-to-text transcription in forms
• Routing prompts through OpenRouter for model hot-swapping
• Setting token limits to control API costs

Fields vs Feeds — choose the right integration point

	OpenAI Fields	OpenAI Feeds
Trigger	Before submission (real-time)	After submission (async)
User waits?	Yes — keep prompts fast	No — background processing
Use for	Live translation, grammar check, real-time summary, image preview	Email drafts, DB tagging, routing, moderation, classification
Token budget	Small (user is waiting)	Larger acceptable

Rule: Default to Feeds unless the use case requires real-time display before the user submits.

Procedure

1) Install via Spellbook

Gravity Connect is not a standalone plugin — it installs through Spellbook (the Gravity Wiz platform):

1. Install and activate Spellbook from your account dashboard: https://gravitywiz.com/download/spellbook
2. In wp-admin: Spellbook → Connect → OpenAI Connection → Install
3. Or activate from your account: https://account.gravitywiz.com/

# After downloading Spellbook zip
wp plugin install spellbook.zip --activate
# Then install OpenAI Connection from the Spellbook UI in wp-admin

2) Connect your OpenAI account

1. Create an API key: https://platform.openai.com/api-keys
2. In wp-admin: OpenAI Connection → Settings → Secret Key → paste key
3. Important: Store in wp-config.php constant, not the settings UI:

// wp-config.php
define('OPENAI_API_KEY', getenv('OPENAI_API_KEY'));

3) Configure OpenAI Fields (real-time)

1. Form editor → Advanced Fields → OpenAI field
2. Set Endpoint (Text, Image, Audio)
3. Write Prompt using Gravity Forms merge tags: {field_label:1}, {all_fields}
4. Set Maximum Tokens — always required

4) Configure OpenAI Feeds (post-submission)

1. Form → Settings → OpenAI
2. Add New Feed
3. Choose model (e.g., gpt-4o-mini for cost efficiency)
4. Write prompt with merge tags
5. Set Maximum Tokens (required — see token ceilings below)
6. Map the AI response to a field or send via notification merge tag

5) Token ceilings — always set

Every feed and field must have Maximum Tokens set to prevent runaway costs.

Task	Recommended max tokens
Categorization / routing	50–100
Email subject line	50–75
Email body draft	200–400
Summary	150–250
Grammar / rewrite	100–200
Moderation decision	50–100
Image prompt → image	256 (tokens don't apply to image size)

6) OpenRouter — hot-swap models without code changes

Route through OpenRouter to use cheaper open-source models:

OpenAI Connection → Settings → Custom Base URL:
  https://openrouter.ai/api/v1

Model examples:
  meta-llama/llama-3-8b-instruct  (cheap, fast)
  anthropic/claude-3-haiku         (quality, affordable)
  mistralai/mistral-7b-instruct    (open source)

Use cheaper models for tagging/categorization feeds; expensive models only when quality matters.

7) GPT Image generation

Field type: OpenAI → Image. Add to form for pre-submission image preview or post-submission image storage.

Prompt: "Professional headshot of {Name:1}, corporate style, white background"
Size: 1024x1024
Store URL in: Image Field 5

Security and cost controls

// wp-config.php — credentials in constants, not wp_options
define('OPENAI_API_KEY', getenv('OPENAI_API_KEY'));

// Set spending limits in OpenAI Platform dashboard:
// https://platform.openai.com/account/limits

Set alerts in your OpenAI project dashboard for unexpected spend spikes.
