JSON Copilot

AI Copilot: Understand, Analyze & Document JSON with AI

By Dmitrii Kargashin · Updated February 2026

AI Feature New

Run AI actions on your JSON straight from the editor: explain it, generate a schema, document it, or repair it. Use credits to run actions, close the panel while they process, and find results in your history.

Available AI Actions

Open the AI Copilot panel from the left sidebar to access these actions:

  • Explain JSON: A human-readable explanation of each field: its purpose, type, and relationships
  • Flatten JSON: Convert nested JSON into flat dot-notation key-value pairs. See the full article
  • JSON Schema: Generate a JSON Schema from your data with inferred types, required fields, and constraints
  • Schema + Describe: Generate a JSON Schema with AI-written descriptions for each property
  • Test Data: Generate sample data and variations from your JSON for testing
  • Fix & Validate: Repair invalid JSON in one click. The AI quotes unquoted keys, removes trailing commas, and closes missing brackets, then returns valid JSON

Coming soon: Explain Structure (concise type and nesting overview), and more.

Mind Map Sync

Several actions (Explain JSON, Flatten, JSON Schema, and Schema + Describe) have bidirectional sync with the mind map and editors:

  • Click a property in the AI result to focus the matching node on the mind map and highlight the JSON in the Output tab
  • Click a node on the mind map to highlight the matching property in the AI result panel and scroll to it
  • Place your cursor in the editor to see the corresponding property highlighted in the AI result

How Credits Work

Each AI action consumes credits based on the size of your input. Before running an action you'll see an estimated credit cost. If actual usage comes in lower than the estimate, we refund the difference to your balance.

  • New accounts receive free signup credits to try AI features
  • Credits can be replenished via subscription plans or one-time credit packs
  • Your balance shows in the sidebar

Good to Know

  • Privacy: Your JSON is sent to our servers only when you explicitly run an AI action. Core features (formatting, validation, minification) always run locally in your browser.
  • History: Every AI request is saved in your Copilot history, so you can revisit past results without spending additional credits. You can close the panel while an action is processing, and the result will appear in history when it finishes.
  • Mind Map Sync: Click a property in the result to focus the matching node on the mind map and highlight it in the Output tab, and vice versa.

Client-Side First: Core operations run in your browser. AI features are optional and use credits.
