Quick answer

Most people can start free with one general assistant (ChatGPT, Gemini or Claude), add NotebookLM for document Q&A, and use Copilot only if Microsoft 365 is already central to their day. Free tiers are enough for drafting, summaries and light research; paid plans matter when you hit usage caps, need longer context, team features or stronger coding and file workflows.

How this was checked

Free-tier limits, model access and feature names change frequently. This page describes typical use cases and links to official product pages rather than hard-coding current quotas or prices.

Best first free assistant ChatGPT, Gemini or Claude

Pick whichever sign-in you already have. Test drafting, summaries and file upload on your real tasks.

Document Q&A NotebookLM

Strong free option when your sources are PDFs, articles or lecture packs.

Microsoft users Copilot in Edge or M365

Useful for quick web tasks or Office users, but not a replacement for every paid Copilot feature.

Cited web answers Perplexity free tier

Helpful for research prompts where source links matter more than long chat memory.

What people search for

What free tiers are genuinely useful

Drafting emails, meeting notes, study summaries and first-pass planning.

Explaining technical topics in simpler language.

Generating practice questions from your own notes.

Searching and comparing options before a purchase or project decision.

Light coding help, regex fixes and spreadsheet formula suggestions.

Where free tiers usually fall short

Heavy daily use that hits message, upload or model-access limits.

Long-running projects that need persistent memory across weeks.

Team workflows with shared workspaces, admin controls and billing.

Advanced coding agents inside your repository or enterprise document security.

Priority access to the newest flagship models at scale.

A sensible free stack

One general assistant for writing and brainstorming.

NotebookLM if you live in PDFs, papers or slide decks.

Perplexity when you need linked sources quickly.

Copilot only if your files already live in Microsoft 365.

Upgrade one tool only after you can name the exact weekly task that the free tier blocked.

Performance guide scope

This guide is written for players everywhere. Norway-specific retailer, warranty and price comparison advice belongs in the hardware buying guides, not in FPS, settings or benchmarking pages.

FAQ

Do I need a paid plan to start?

No. Most knowledge workers and students can learn useful patterns on free tiers first. Pay when a specific workflow repeatedly hits limits or needs enterprise controls.

Which free tool is best?

There is no universal winner. Use the assistant you can sign into today, run three real tasks, and keep the one that needs the least cleanup on your actual work.

Sources and methodology

Performance guides combine official documentation, benchmark tools, public hardware trend data and repeatable testing habits. Always measure your own system before changing several settings at once.
