Chapter 8. Start free, and decide when to pay

Key points

• Free is enough at first; there is no need to spend from the start
• Consider paying when you need speed, long documents, more files, or automation
• Where your work jams is what tells you which plan to buy

Free is enough at first

Gemini Notebook, ChatGPT and Claude can all be started free. There is no need to bring in an expensive tool from day one.

• free generative AI
• the files you already use
• cloud storage, if you need it

Combining these gets you a long way. Learning the feel of handling files with AI comes first.

What paying actually changes

Use it hard enough and you meet the free limits. Paid tiers mainly strengthen:

• processing speed
• how well it handles long documents
• limits on files and requests
• access to more capable models
• code execution and advanced data analysis
• automation and agent features

The shape of the main paid plans

• ChatGPT Plus — easier access to the strongest models, code execution and advanced data analysis. A good fit for work involving data: CSV analysis, charts, organising research data.
• Claude Pro — stronger long-document analysis, large-scale editing and document handling. Suits research, writing and teaching.
• Gemini Notebook paid — much higher limits on sources, chats and audio generation. For researchers reading papers in volume.

Prices and limits change easily; always check the current official information before subscribing.

How to decide — look at where you jam

If you cannot decide what to pay for, use what jams in your own work as the criterion.

• reading large volumes of papers daily → paid Gemini Notebook
• handling long manuscripts and documents often → Claude Pro
• repeatedly aggregating and charting data → ChatGPT Plus

Rather than subscribing to everything because it all looks good, use the free tiers hard and then unlock the one point that genuinely jams. That is the cost-effective route.

Try this

Use the free tiers seriously for a week. Note the moments where you hit a limit, or wish it were faster. Those notes will tell you which paid plan is right for you.

Chapter 8 summary

• Free is enough at first; do not subscribe immediately
• Paid tiers strengthen speed, long documents, request counts and automation
• Pay for the one point that jams in your own work, and nothing else
