Chrome Extensions by SignalCrate — small tools that fix one daily annoyance

We build small, single-purpose Chrome extensions. Each one fixes exactly one daily annoyance, works the moment you install it, and asks for the fewest permissions that can possibly do the job. The core of every tool is free; a paid tier unlocks heavy-duty use once the tool has already proven useful to you.

The lineup

• Comment Exporter for YouTube™ — CSV · Export the public comments of any YouTube video to CSV or JSON. Auto-scrolls the thread, captures authors, likes and timestamps, and hands you a clean spreadsheet. For creators, moderators and researchers. Status: coming to the Chrome Web Store.
• Tab Search for Google Sheets · Double-tap Shift, type a few letters, jump to any sheet tab. Fuzzy matching, keyboard-first, built for workbooks with 30+ tabs. Status: coming to the Chrome Web Store.
• Row & Column Highlighter for Google Sheets · An Excel-style focus crosshair for Sheets: the active row and column light up so you never lose your place in a wide sheet. Status: coming to the Chrome Web Store.
• Attachment Downloader for Gmail™ — Zip All · Every attachment in a thread, one click, one zip, auto-renamed. No OAuth grant, no server — it runs entirely in your browser. Status: coming to the Chrome Web Store.
• Chat Navigator for ChatGPT & Claude · A collapsible outline of your prompts in long AI conversations. Click any prompt to jump straight back to it. Status: coming to the Chrome Web Store.

How pricing works

Install free, use the core feature free, forever. When you hit power-user volume — bulk exports, many workbooks, long threads — the tool offers a paid tier (consumer-priced, cancel anytime, handled by ExtensionPay/Stripe). You will never hit a paywall before the tool has done something useful for you.

Privacy stance

These extensions run in your browser. None of them send your page content, mail, sheets or chats to our servers — we do not have servers for them. Payments are handled by ExtensionPay; the only network calls are the ones that make payment work.
