AI Tools Guide
Everything we've published about the AI tools that ship today — ChatGPT, Claude, Gemini, and NotebookLM — grouped by what you're actually trying to get done.
Hands-on guides for the AI assistants people use now, organized by the outcome you want rather than the vendor's marketing. We re-test each walkthrough against the current app, because these tools change their interfaces almost weekly.
In short.
An evergreen hub for the AI tools that work today: how to use ChatGPT, Claude, Gemini, and NotebookLM, plus side-by-side comparisons and which one to pick for a given job.
Vendor docs are written to sell features, and most readers know the task they want done, not the tool that does it best. We organize around the outcome and re-test against the live apps.
Start here if you are new to a tool or trying to decide between them. For a specific error like voice mode failing, jump straight to the matching fix guide in the list below.
Where most people start with AI tools
Five habits worth setting up before you go deeper with any AI assistant.
- 01
Pick a default tool, then add a second for its strength
No single assistant wins every task. Most people do best with one daily driver plus a second tool for the job it clearly leads on — writing, coding, or source-grounded research.
- 02
Write custom instructions once
ChatGPT, Claude, and Gemini all let you store standing context — your role, tone, and what to skip. Setting this once removes the same preamble from every future chat.
- 03
Verify anything factual against a real source
All of these tools still invent confident-sounding details. Treat dates, figures, quotes, and citations as drafts to check, not answers to trust.
- 04
Decide before you pay for a Plus tier
The paid tiers mostly buy faster models, higher limits, and a few exclusive features. Check whether the free tier already covers your actual usage first.
Our paid-tier guides break down exactly what the upgrade does and does not unlock.
- 05
Keep private data out of general chats
Default consumer plans may use your prompts to improve models. Turn training off in settings, or use a tool like NotebookLM that answers only from sources you control.
