5 Prompts that replaced 5 paid subscriptions
Not perfect. Good enough to cancel the subscription. That's the bar.
A Reddit user cancelled five paid tools and got back $120 a month. The replacement for each one was a single prompt.
The post landed on r/PromptEngineering this week. No course pitch. No affiliate links. Just what actually worked, laid out in full. Here are the five prompts and why each one works.

How Jennifer Aniston’s LolaVie brand grew sales 40% with CTV ads
For its first CTV campaign, Jennifer Aniston’s DTC haircare brand LolaVie had a few non-negotiables. The campaign had to be simple. It had to demonstrate measurable impact. And it had to be full-funnel.
LolaVie used Roku Ads Manager to test and optimize creatives — reaching millions of potential customers at all stages of their purchase journeys. Roku Ads Manager helped the brand convey LolaVie’s playful voice while helping drive omnichannel sales across both ecommerce and retail touchpoints.
The campaign included an Action Ad overlay that let viewers shop directly from their TVs by clicking OK on their Roku remote. This guided them to the website to buy LolaVie products.

The campaign helped drive a big lift in sales and customer growth, helping LolaVie break through in the crowded beauty category.
Replacing Grammarly ($30/month)
Read this and fix it. Not just grammar. Fix it if it sounds like it was written by a committee, if the point is buried, or if any sentence could be cut without losing anything. Tell me what you changed and why before showing me the rewrite. Text: [paste here]
The key move here is asking for the reasoning before the rewrite. You see the diagnosis, not just a cleaned-up draft. Grammarly gives you a green squiggle. You never know why. This prompt shows you why, and that feedback loop is what actually makes your writing better over time.
Replacing content scheduling software ($49/month)
Plan my content week. My niche: [one line]. My audience: [describe]. This week I want to be known for: [one thing]. 5 post angles worth writing. For each: first line only, the argument underneath it, platform it suits best. Replace anything that sounds like something anyone in my niche could write.
That last line is doing the real work. It's a built-in quality filter. Most scheduling tools will happily fill your calendar with content that sounds exactly like everyone else. This prompt won't let you get away with that.
Replacing the Monday planning session
Here's everything in my head: [dump tasks, worries, unfinished things, deadlines, all of it]. 1. What actually needs to happen this week. 2. What I'm avoiding and why. 3. The one thing that makes everything else easier if done first. 4. Monday in three actions. Not a list. Just three things.
Question two is the one most planning tools skip. What you're avoiding and why. That's not a task management question. That's a thinking question. Having to answer it in writing changes the answer. I started using this one on Mondays and honestly the "what am I avoiding" part alone is worth it. Turns out I was avoiding the same thing 3 weeks in a row.

Replacing proposal software ($39/month)
Turn these call notes into a formatted proposal I can paste into Word and send. Notes: [dump everything as-is]. Client: [name]. Investment: [price]. Executive summary, problem, solution, scope, timeline, next steps. Formatted. Sounds human. Ready to send.
"Sounds human. Ready to send." That's the brief, and it's the right one. Most proposal software outputs something that reads like it was assembled by a legal team in 2009. If you're sending more than probably 3 or 4 proposals a month, this prompt pays for itself on day one.
Replacing the weekly review
Here's what happened this week: [rough notes, wins, problems, anything relevant]. What actually moved forward. What stalled and why. What I'm overcomplicating. One thing to drop. One thing to double down on.
Five questions. No padding. The third one, "what am I overcomplicating," is the kind of question a good coach asks in week three when they've figured out your patterns. the AI asks it every single week without getting tired of you.
Why these prompts actually work
Three things run through all five:
They front-load enough context so the AI knows what good looks like in this specific situation
They ask for structure and specifics, not open-ended output
They're built to be used on a schedule, not tried once and forgotten
The original poster said it plainly: none of these are perfect. All of them are good enough that he stopped paying for the alternative.
That's the bar worth aiming for. Not perfect. Good enough to cancel the subscription.
Who these work best for
If you run a solo operation and handle your own writing, planning, and client work. If you send proposals more than a few times a month. If you manage your own content calendar. If you spend Monday mornings unclear on what the week actually needs.
The Monday planning and weekly review prompts work especially well as a pair. Use one to open the week and the other to close it. That loop alone replaces a lot of time spent spinning.
Start with the Grammarly replacement. Paste in something you've been putting off sending. Read the explanation before the rewrite. That part, knowing what changed and why, is what no $30/month tool was ever giving you.
