Stop Wasting Money on AI Tools You Don't Use

Which AI subscriptions actually pay for themselves? Claude, ChatGPT, Perplexity ranked by real use cases. Skip the hype, keep what works.

In short

  • Claude Pro and free ChatGPT cover most daily work; paid plans only make sense if you hit usage limits or need specific features.
  • Perplexity excels at research with citations, Obsidian is free for note-taking, and most other tools are either redundant or niche.
  • Audit your subscriptions by checking 30-day usage; if you open a tool fewer than five times, cancel it and try again later.
  • Local AI saves money but trades cash for hardware costs and technical setup; cloud subscriptions are faster for most people.

The Real Problem: Paying for Tools You Barely Touch

Most of us have a subscription list that looks like a budget leak. Claude Pro, ChatGPT Plus, Perplexity, maybe Kling credits adding up without a clear reason. The question isn't whether these tools are good—it's whether you're actually using them enough to justify the cost.

The video above goes deeper into each tool, but the core issue is simpler: we sign up for the hype and then barely open the app. Paying for an AI tool only works if you use it every day. Otherwise you're just funding someone else's infrastructure.

Which Paid Plans Actually Earn Their Keep

Claude Pro costs $20 per month and is worth it if you're using Claude daily. [3] [19] The free version has a message limit that stops you cold after a few questions. The paid plan removes that ceiling and gives you access to Claude's most capable models. Users report Claude produces clean, well-structured output with no fluff, especially for writing and automation tasks like triaging email or summarizing documents.

ChatGPT Plus also costs $20 per month, but here's the honest take: maybe skip it. [19] [20] Free ChatGPT gives you the current model with image generation, web browsing, and voice. You hit the paid tier only if you need more speed or priority access. Most people don't. ChatGPT is faster for quick research and brainstorming—you ask something and get an answer in seconds—but the free version handles that fine unless you're hammering it all day.

Perplexity Pro costs $20 per month and is built for research. [21] Users report it finds recent data, cites sources with dates and numbers, and it's faster than googling. The free version has search limits, but test it first before paying. Some users find the paid tier helpful; others say the limits are restrictive enough that free works fine.

Obsidian is free and stays free for the core app. It's a local note-taking tool that lives on your computer with no cloud vendor lock-in. Paid add-ons exist, but whether they're worth it depends entirely on what you're doing.

Tools to Skip or Use Only as Backups

Gemini is free and decent for quick tasks, but users report it's slower than Claude on writing and struggles with research. Use it as a backup. Skip the paid plan entirely—the free version works fine for casual use.

Replika is an AI chatbot meant to be your friend. It's not useful for work and the conversation is shallow. Sudowrite is a writing assistant, but users say it felt limited next to Claude or ChatGPT; you're paying for a specialized interface that doesn't add much. Copy.ai is a template-based copywriting tool with generic templates and mediocre output. Claude or ChatGPT will beat it every time.

Mistral is an open-source model that people experiment with, but running it yourself needs significant hardware and technical setup. Small open models need around 16 gigabytes of RAM. Big 70-billion-parameter models need a serious GPU. Most laptops can't run them.

Notion is powerful for notes and databases, but some users find it has more features than they need and the interface feels overwhelming for basic note-taking.

Three Steps to Audit Your AI Spending Right Now

Step one: list every AI subscription you're paying for right now. Write them down. Most of us have more than we think.

Step two: check your last 30 days of use. Did you actually open it? How many times? If it's less than five, you're probably not getting value.

Step three: keep the one you use every day. Cancel or pause the rest for a month. You can always turn them back on if you miss them. The real cost isn't the subscription—it's the time you spend learning the tool and figuring out what it's good for. Spend a week with one tool before you buy the next.

Local AI vs. Cloud: The Trade-Off Nobody Talks About

Some people run local AI to save money. You install a free app like Ollama on your computer and run an open model without paying a subscription. That works if you have the hardware and the patience. But you're trading money for time and technical headache. For most of us, paying for cloud AI is faster because you don't have to maintain the setup or wait for inference on underpowered hardware.

If you do want to go local, know what you're getting into. Small models need around 16 gigabytes of RAM. Bigger 70-billion-parameter models need a serious GPU. Most laptops can't run them. You're looking at a mini PC or a dedicated build, which costs money upfront and time to configure. The math only works if you use it constantly.

The Core Stack: What Most People Actually Need

Claude and ChatGPT are the core. One of them covers writing, research, automation, and brainstorming. Pick the one that fits your workflow and stick with it. Perplexity if you do serious research. Obsidian if you want to own your notes and don't mind learning the app.

Everything else is optional. If a tool isn't saving you real time or money, don't pay for it. The honest part: a lot of us sign up for paid plans and then barely use them. That's not a failure of the tool. It's a sign you didn't need it in the first place.

Alternatives exist: stay on free tiers if you don't hit the limits every day. Free Claude, free ChatGPT, and free Perplexity work for most casual use. Or pay for just one tool and use it for everything. One plan you open every day beats three you barely touch. The goal is to cut the noise and keep what actually moves the needle.
