## Description

Lightning Autofill is a powerful Chrome extension that streamlines form filling, automation, and text expansion to save time and reduce repetitive typing. It fills far more field types than the browser’s built-in autofill (text inputs, checkboxes, radios, selects, rich text editors, and more), supports smart targeting via CSS/XPath/regex, and can recover form data after crashes. Advanced features include macros/JavaScript rules for clicking and submitting, random data generation, hotkeys, profiles, and local import/export.

Choose from Free, Plus (unlimited executions + Google Sheets cloud sync), or Pro (Plus features + JavaScript rules, variables, and reCAPTCHA support). Lightning Autofill is privacy-focused — no tracking or analytics by default — but data stored locally is not encrypted, so avoid autofilling highly sensitive items unless using secure measures. Try Plus or Pro risk-free with a 3-day free trial.

## Review summary

User reviews largely praise the add-on for autofilling fields, especially with multiline textareas, and some positive remarks like “Nice Apps.” However, the dominant dislike centers on pricing and licensing changes: persistent monthly subscription fees, a move to freemium/Pro under MV3, and gating that disrupts usage. A few users report reliability issues or interruptions when updating or hitting limits. Overall, opinions split between perceived usefulness and frustration with monetization and update model.

### Pros

- Works with textarea (multi-line text)
- Nice Apps
- Core autofill functionality for filling form fields

### Cons

- Monthly subscription / recurring cost (5 € / $5 per month)
- Shift to freemium model with Pro and MV3 migration (paywall after many years)
- Pro upgrade prompts disrupt usage / licensing gating (update to Pro)
- Occasional reliability issues and usage limits (e.g., daily limit)
