The Problem
If you've ever tried to use an online keyword mixer for Google Ads campaigns, you know the pain:
- Ads everywhere — ironic for a tool meant for ad professionals
- Login walls — "Enter your email to continue"
- Slow and laggy — especially with large keyword lists
- Data collection — your keyword strategy sent to some server
The Solution
I built Keyword Mixer — a free, browser-based tool that does one thing well: combine keyword groups into every possible combination.
Features
- 3-5 keyword groups with dynamic add/remove
- Match types: Broad, Phrase (""), Exact ([])
- Copy All + CSV download
- Duplicate removal toggle
- Custom separators
- Real-time combination count
- Dark/Light theme
- Zero ads, zero tracking, zero login
How It Works
Paste your keyword groups, pick your match type, and get every combination instantly. Copy to clipboard or download as CSV — ready for Google Ads Editor.
Example:
Group 1: buy, get, find
Group 2: cheap, best
Group 3: shoes, sneakers
Result: 12 combinations like buy cheap shoes, get best sneakers, etc.

💬 Your Turn
What free tool do you wish existed but nobody has built yet? I build micro tools as a side project and I'm always looking for ideas that solve a real itch.
What about you?
- What's one developer/marketing tool you built just because the existing ones annoyed you?
- Do you actually use Google Ads keyword tools, or do you have a different SEO workflow?
- Would you contribute to an open-source marketing toolkit if one existed?

Nice work building this as a fully client-side tool — the zero-tracking angle is a big deal when you're literally typing your ad strategy into a text box. Most people don't think twice about where those keywords end up.
The match type support is a solid touch too. Curious if you've thought about adding negative keyword generation as part of the mix? That's usually the next headache after building out your keyword combos.
I've been working on something in a similar spirit for social media — postammo.com generates viral content ideas and hooks so you're not staring at a blank scheduler all day. Same philosophy: give people a focused tool that does one thing without the bloat.
Thanks @chovy! Really appreciate the thoughtful feedback. The zero-tracking angle was honestly the main motivation. Negative keyword generation is a brilliant suggestion — adding it to the roadmap! If you have other ideas, I'm all ears.
