Description
JSON Lens AI is a privacy-first Chrome extension that turns any raw JSON response into an interactive playground – with AI super-powers built in.
–––––– WHAT IT DOES ––––––
• **Automatic detection** – Instantly opens any `application/json` response or <pre> snippet in a dedicated viewer – no copy-paste.
• **Beautiful tree + raw view** – Collapse / expand, jump by JSONPath, breadcrumb navigation, dark-mode toggle.
• **Blazing search** – Find keys, values (or both) with regex & case-sensitivity.
• **AI insights (Gemini powered)**
› Summarise entire payloads.
› Ask natural-language questions (“Which items cost > 25000?”).
› Infer schema types & explain any selected node.
• **Copy helpers** – One-click copy of JSONPath, individual values, or entire sub-trees – perfect for tests and scripts.
• **Customisable UX** – Font size, indentation, light/dark theme.
• **Works offline** for all non-AI features. Your JSON never leaves the browser.
–––––– WHY INSTALL ––––––
🛠 Saves hours when debugging REST APIs, webhook payloads, LLM outputs and log files.
⚡ Replace multiple dev-tools with one tab.
🔐 Client-side only; Gemini calls use **your** API key. No tracking.
–––––– IDEAL FOR ––––––
• Full-stack & frontend developers
• AI / ML engineers wrangling LLM JSON
• DevOps & QA teams inspecting logs
• Students learning APIs
–––––– GET STARTED ––––––

2. Visit any JSON endpoint – JSON Lens AI pops open automatically.
3. (Optional) Add a Gemini API key in **AI Settings** to unlock summaries & NLQ.
