There a plenty of AI/GPT 3 writing tools, and it seems they all work fine. I am still amazed how quickly good text can be generated.
However, I bought writecream for two reasons which sets it apart from the other AI writing lifetime deals here:
1) csv upload. To my knowledge none of the other writing tools here offer that.
2) create content from a link for the icebreakers

I currently upload a list of prospect's emails or websites, and quickly get a cold mail icebreaker paragraph for each prospect. Sometimes it is a bit too generic to use directly, but it still saves 2 minutes of my time per prospect. And this adds up in time saving, 30 prospect per day = 1h saved with writecream.
I'd really love to see this developed, and the ability to add some individual keywords to the csv and the icebreaker outcome, and maybe other styles (e.g. summary from link).

But for me, already the icebreaker feature from link/csv is clearly worth the deal.
