Student discounts make paid software look cheap, and cheap software still adds up. The useful test is not whether a tool is good but whether the paid tier does something the free tier cannot, for a job you do often.
Here is that test applied category by category.
Worth paying for
Cloud storage, once you exceed the free tier
Not for the space — for the version history. Being able to restore a document to how it looked three days ago is the feature that rescues dissertations, and it is usually the thing that disappears at the free tier’s edge. If you are producing a large piece of work, this is the cheapest insurance available.
A reference manager, if you write with citations often
Free tiers usually cap your library size or your sync devices. If you are in a research-heavy programme, hitting that cap mid-project is disruptive in a way that costs more than the subscription.
One AI assistant, if you use it daily
Emphasis on one, and on daily. Three subscriptions to overlapping assistants is the most common way students waste money now. If you are opening it every day to work through explanations or generate practice questions, a single paid tier is defensible. If you use it twice a week, the free tier is fine.
Not worth paying for
Note-taking apps
The free tier of every major note app covers what a student needs. The paid features — large file uploads, advanced search, team spaces — solve problems you do not have. Spend the money on nothing and keep the note app you already opened.
Grammar and writing checkers
The free tier catches the errors that matter. The paid tier mostly rewrites your sentences into a blander register, which is actively unhelpful for academic work where your tutor is assessing your reasoning, not your fluency.
Calculator and converter tools
There is no version of a weighted average that costs money. A free tool that shows its formula, handles credit weighting properly and works on a phone is the whole requirement — which is what our CGPA calculator and SGPA calculator do. If a grade tool asks for a subscription, the thing you are paying for is the interface, not the arithmetic.
Habit trackers and “second brain” systems
High abandonment rate, and the paid tier does not change that. Use the free version for a month before paying for anything in this category; most people stop opening it by week three and the subscription quietly renews for a year.
The middle ground: pay per project
Some tools are worth paying for during one specific month and not the rest of the year. A design tool during the month you build a portfolio. A transcription service during the weeks you run interviews. A PDF suite during application season.
The discipline is cancelling afterwards. Set a calendar reminder on the day you subscribe for two days before renewal — this one habit saves more money than every student discount combined.
A quick audit
Open your bank statement and list every recurring software charge. For each, answer two questions: when did I last open this, and what would break if I cancelled it?
Anything you have not opened in a month, or where the honest answer to the second question is “nothing”, goes. Most students find two or three, and the total is usually more than they expected.
The spending that beats software
If you have a fixed budget for improving your studying, a better chair, a second monitor, decent headphones and a reliable backup drive will each do more for your output than another subscription. They are one-off costs, they do not renew, and they work on every piece of software you already have.
