Which AI tool to use: a free guide for images, video, voice, music, research and agents

Mindket editors · Updated · 6 lessons · 56 min

A black banner titled "Which AI tool to use" over the line "Images, video, voice, music, research and agents".

This free course helps you pick the right AI platform for each job: making images, video, voice and music, researching a question, and building an AI agent. Each lesson compares the main platforms on what they do best, the free plan, the price on the vendor's own page and the limits, then gives a short way to choose and start. No code is needed.

What you'll be able to do

  • Pick an image generator by what you need: words inside the picture, photo edits, a house style or commercial use.
  • Choose a video generator by clip length, sound, price per second and where you may use the result.
  • Match a voice tool to the job: reading text aloud, turning speech into text, cloning a voice or changing one live.
  • Make music and sound effects with AI, and know what your plan lets you publish.
  • Choose a deep research tool, and choose between a ready-made agent and an agent builder.

Frequently asked questions

Is this guide to AI tools free?

Which AI tool should a beginner try first?

The one with a free plan for the job in front of you today. Each lesson's table marks the free plans, so start there and pay once the free limit gets in the way.

Can I use what these tools make in my business?

It depends on the platform and the plan. Each lesson's table has a column for commercial use, taken from the vendor's own terms.

What should I learn after this course?
