How to get a free mind map from your notes

A renewable energy unit can hold forty terms and several cause-and-effect chains, and a mind map shows how they connect far better than a flat list. When you need to create mind maps for free, start with the material you already have instead of redrawing it by hand.

Example renewable energy sources mind map branches

Solar powerPhotovoltaic panels convert sunlight directly to electricity · Concentrated solar thermal uses mirrors to heat fluid · Solar water heating supplies hot water for buildings

Wind powerOnshore turbines are cheaper to build on land · Offshore turbines get stronger, steadier winds · Kinetic energy from moving air turns the rotor and generator

HydropowerDams and reservoirs store water for generation on demand · Run-of-river systems use natural flow with less storage · Pumped storage moves water between reservoirs to balance the grid

Geothermal energyHeat from the Earth's crust drives steam turbines · Dry steam and flash plants suit high-temperature reservoirs · Binary cycle plants work with lower-temperature fluids

Biomass energyOrganic material is burned or converted into fuel · Wood, crop residue, and municipal waste are common feedstocks · Biogas from decomposing material can be captured and burned

Editable mind maps

Your map is built from the text you upload, and every node can be edited, moved, or reworded.

Explorable branches

Expand or collapse branches to focus on one topic at a time instead of scanning a wall of text.

Works with your files

Upload PDF, DOCX, or PPTX files, plain notes, or photos of pages read with text recognition.

How it works

Upload or paste

Add a PDF, DOCX, PPTX, plain notes, or a photo of your page.

Generate your map

The AI pulls out the main topics and links the subtopics under each one.

Explore and edit

Expand branches, fix anything that looks off, and study the map in your browser.

The free plan includes 3 generations per month, so spend them on the sections you find hardest to remember. Each generated map stays editable, and you can study it right in the browser.

Paid plans remove the monthly limit. Plus at $99.90/year or $9.99/month adds PDF, DOCX, Anki, and CSV export, and Pro at $14.99/month adds a stronger AI model.

Frequently asked questions

How do I organize renewable energy sources in a mind map?

Start with the main categories, such as solar, wind, hydro, geothermal, and biomass, then add how each one produces power and its main advantages and limits beneath it.

What should a renewable energy mind map include?

Include each source's energy conversion method, typical uses, and tradeoffs like intermittency or land use. Linked branches make it easier to explain why one source fits a location better than another.

Can I export my free mind map?

The free plan lets you study in the browser but does not include exports. Plus adds PDF and DOCX export, and students get 40% off with a school email.

How many mind maps can I create for free?

The free plan includes 3 generations per month. Paid plans offer unlimited generations.
