How do you decide what features should be free and what should be paid?
Let me start from the creator’s perspective:
I personally don’t have a product (apart from hiring people for creative work or offering personal consultations).
But as a creator, I constantly share content, insights, and information, value that helps me build trust (for free). Based on that perceived expertise, people eventually decide to work with me (a paid service).
So some things I share for free to eventually move toward a paid collaboration.
Personally, it’s sometimes hard to judge when I might be giving away too much for free.
And I assume it’s similarly tricky for builders.
You want users to try the product, but then comes the question of paid features, or a trial limited by time or usage.
How do you decide which parts of your product or service remain free, and which become paid?
When I share content publicly, I usually provide generalised advice. But when it comes to a specific case or a tailored strategy that requires a personal approach, that’s where it becomes paid.

IMO free should show the value, paid should unlock serious/repeated use.
For Theoria for example I keep the basic experience free: people can find research, read simple explanations, and see if it’s actually useful for them.
The paid part starts when someone wants to go deeper or use more expensive AI features again and again, like asking detailed research questions, getting deeper paper analysis, creating audio summaries, or finding practical uses from research.
So my rule right now is:
Free = help users get the “ok wow, this is useful” moment.
Paid = help them save time repeatedly once it becomes part of their workflow.
The hard part is making free useful enough to build trust, but not so complete that there’s no reason to upgrade.
I think some thing people get wrong is they monetize anything that costs them money which isn't bad but I think free tier should at least give an idea of the value a paid service could provide. This lets users try it out and see the value and eventually builds trust.

It’s pretty similar to what you said—general capability is free, but when it gets into reliability, volume, or more tailored/serious use, that’s where we draw the line.
This is the million-dollar question for builders. I recently went through a pivot on this exact logic for my tool, RoastMyLanding.
My rule of thumb now: Diagnosis is Free. The Roadmap is Paid.
I give away a high-level "Trust Leak" audit for free. It shows the founder exactly where they are losing money (the 'what' and 'where'). It builds instant authority because it's tailored to their URL.
But the specific, 10-point execution roadmap—the 'how' to fix it—is what's behind the paywall.
I've found that if you give people a clear diagnosis for free, they don't feel like you're "selling" them; they feel like you're helping them. At that point, the paid tier isn't a hurdle—it’s just the logical next step to solve the problem you just identified.
My takeaway: Don't be afraid to give away the "Why." Just make sure you charge for the "How." 🚀
I think a market analysis has to be done beforehand, just like if you're gonna open a physical store.
That would imply:
- Costs of running your service (hosting, cloud, services like agentic AIs, etc).
- Cost of advertising your services (as you said, offering free content could fall into this).
- Legal costs.
- How much time you would need to reach a break even.
- How much revenue you want to get.
That could help you shape the target of your commercial services.
I think it’s just about when the user starts depending on it.
Free should get them to that “this is actually useful” moment. Paid is when it becomes something they don’t want to lose.
If they haven’t felt real value yet, it’s too early to charge.
The line I use: give away the diagnosis, charge for the cure.
I just put out a free AI Skill File Starter Kit. Templates for Claude and Gemini that people can actually use. Not a teaser. Real, functional files. The reason is simple. When someone uses them and their AI output gets noticeably better, they come back and ask "can you build me a custom version?" I didn't have to pitch them. The free thing did the work.
To your point about giving away too much, I think the risk isn't generosity. It's giving away the wrong thing. If you give away the strategy, nobody needs to hire you. If you give away a tool that shows them the problem, they hire you to solve it.
Free should be general. Paid should be personal. That's the whole framework.
I’m a freelancer. When someone approaches me with a question about my services, I first assess the scope of work and the urgency involved. If the requirement aligns with a brief consultation or a high-level business roadmap, I provide that guidance free of charge.
My priority is to build trust and establish credibility from the outset. Once the client sees value in the initial interaction, I then introduce my paid services in a structured and professional manner.

For my latest app i keep features free, if those don't cost me lot of $$.
for all expensive features (AI, ML, GPU costs) are behind paywall. This is not to make my users pay. its just a guard to make sure hackers don't make me bankrupt! lol.
Eventually, if the users like my product then the $2/month is justified.
With token usage based apps, small businesses like us are in a tough place. We are offering a free audit tier, mainly for potential customers to try out. But we need to time limit that, so we can break even.
