... This is truly a no brainer. Learning about many different workflows and content optimisation techniques over the years and using several "mainstream" content-creation tools I've realised that - regardless of anyone's approach - you will arrive at the same point as everyone else - content briefs, planning and research.
Frase attempts to tackle all 3 of them. And they're doing an amazing job at it!

Pros:
- Clean interface and no-fluff
- Super intuitive and clear FAQ/Tutorials (as they should, given what the tool is for... )
- I can't see any apparent bugs and the tool looks robust - all the features I tried worked immediately
- Within the first minutes of use, I already know that I will be saving 80-90% of my time on the research, planning and briefs
- "Paste Brief" - duuude...

CONS:
- Where is Google Ads scraping? You got everything you need to add "Ads Writing Assistant" feature - I hope you'll consider it...
- Same as you have "Paste Brief" one-click, have "Paste Content" with an adjustable keyword count, where H2-H4 headers (incl. Questions) are all added automatically from the brief - it would be a perfect one-click article generator ready for rewriting or spin

Tools/workflow I'm using currently and where I see Frase replacing them:
- Google (obviously...) - Frase will replace manual searches and scrapes
- Grammarly Pro - works with Frase
- CognitiveSEO - I don't think Frase can replace that yet (CSEO is on another level)
- PageOptimizerPro - same as Cognitive, not going anywhere
- Ahrefs Keyword Research - I'll probably still use it, but Frase does a good job in providing the most relevant keywords/questions
- Keywords Everywhere/Answer the Public (for "related searches"/questions) - Frase replaces that
- Ahrefs Content Explorer (and SocialAnimal) - maybe not as good as Ahrefs but for content writing, Frase is excellent
- AutomaticScript.com - I'll keep using it for Ads and newsletter content I guess...
and
- SEO Content Machine NEXT:
SCM's "Article Writer" comes closest to Frase but you don't get a brief, and the scrapes are just too overwhelming imo - even with filtering, provided snippets require a looot of manual sifting through. SCMN is amazing for other SEO-things, and it's a subscription with a desktop-only application (no cloud, no extra "seats").

Use case:
Last Monday I was assembling content for a solar panel company and using all tools above it took me a total of 12 hours to put together a medium-size company website with additional services, silo structure and MVP-keyword research.
For fun I've plugged "solar panels" to Frase's "OpenWeb" - and right away, I can see that I could gather almost everything I need in 2-3 hours tops. That is 9-10 hours of free time I'd be getting using Frase.

If you're doing SEO and don't see a value in this tool - you're either using some (expensive) alt tool or... you're doing something wrong - in which case I recommend you trying Frase - it might be a game-changer for you. It is for us.
