How to Use
- 1
Choose a starter before writing
Choose one of the eight starter maps first: selecting a starter replaces the topic, branches and details. Use Launch for the fictional library-essay example below; it has four branches with three details each.
- 2
Turn your topic into paragraph groups
Click the central label and type your topic. Rename each branch for a main point, then replace its details with short supporting prompts. Add branch creates another group; selecting a branch and choosing Add idea adds a detail.
- 3
Check the ideas and their relationships
Keep each detail under the branch it supports. In a map layout, dragging changes its position and the connecting lines follow; it does not move the idea into another branch. Mark questions and assumptions that still need research.
- 4
Choose a readable view
Choose Tree for an outline or Cards for a report. Layout and canvas-size changes keep your labels but reset manual positions. Keep labels concise and inspect the whole map for clipped text before downloading.
- 5
Download or save your outline
Download PNG creates a standard image for free without signing in. Open the downloaded file to check every label. Save requires an account for reopening an editable design; SVG, HD PNG and MP4 require Pro access or an active export pass.
Why Choose GraphMake?
Worked example: a fictional library essay
This is a fictional planning exercise, not a description of a real library. The writing question is what a community library could offer and what would need checking before making a recommendation. Choose Launch before typing, keep Studio blue, Compact and 100% text, then rename the central topic to Fictional library essay.
Rename Audience to Access, with Weekend hours, Step-free entry and Clear signs as its three details. Rename Channels to Learning, with Homework club, Skills workshops and Reading groups.
Rename Launch assets to Community, with Local stories, Meet-up space and Noticeboard. Rename Timeline to Questions, with Staffing needs, Running costs and Visitor feedback. Replace all twelve starter details so unrelated launch prompts do not remain in your outline.
Choose Tree to see the topic and four paragraph groups, then Cards to compare the same groups as a report. The labels stay the same. In Compact at these settings, the tested example downloads as a 900×700 PNG in either view.
Before drafting, turn the Questions group into a research checklist. Find evidence for the suggestions, decide which groups support your argument, and write an introduction and conclusion separately. The map is a starting outline, not proof that any proposed service is needed or affordable.
Keep the structure useful as you edit
Give each branch one job. If two branches repeat the same point, revise their labels or combine their ideas deliberately. Moving a node closer to another branch does not change its parent, and vertical placement in Tree does not create extra levels of nesting.
Keep details short enough to read in the final image. A sentence may fit in the editable text while only part of it is visible on the map. Shorten it to a prompt and keep the explanation and sources in your draft. Check the exported image rather than assuming every typed word is visible.
Select a branch to change its color; its details follow that color. A theme applies a new palette. Choose your layout and canvas size before fine positioning because either change resets manual placement. Reset layout restores automatic positions without replacing your labels.
Choose the guide that matches your next task
Use brainstorm map maker when you are still collecting possibilities and mind map maker for broader notes and planning. They share this editor. For a deeper hierarchy or a network of labelled relationships, compare tree diagram maker and concept map maker before committing to a structure.
For a class handout or slide, download the standard PNG and inspect it at its intended viewing size. For later editing, save the design to your account as well. On a phone, preview panning and Expand can help inspection; neither guarantees that a dense map will be readable in a small final image.
What You Can Create
Planning an essay
Separate a writing question into paragraph groups, supporting prompts and evidence still to find before drafting.
Organizing revision notes
Group a topic into concepts, examples and questions to revisit, keeping labels short enough to read on the exported map.
Outlining a proposal
Distinguish possible benefits, practical constraints and unanswered questions before turning an idea into a researched proposal.
Frequently Asked Questions
How does an idea map help with writing?
Use the central topic as your writing question, branches as possible paragraph groups, and details as supporting prompts or evidence to find. The fictional library example below shows this process. A map organizes your thinking; it does not verify a claim or write the finished essay.
Is an idea map different from a mind map or brainstorm map?
These GraphMake pages share the same editor. This guide focuses on organizing ideas before writing; a brainstorm map emphasizes collecting possibilities, while a mind map can cover broader notes and planning. Choose the guide that fits your task rather than expecting a different diagram engine.
Will choosing a starter replace my work?
Yes. A starter replaces the central topic, branches and details, and resets their positions. Choose it before entering your own material. Layout and canvas-size changes keep the labels but reset manual positions; changing the theme repaints branch colors.
Can I add more levels or move an idea into another branch?
The structure is one topic, branches and details. Add idea on a selected detail creates a sibling under the same branch, not another nested level. Dragging changes placement only. To move a detail between branches, add it under the destination branch and check it before removing the original. Removing a branch also removes its details.
Why is part of a long label hidden?
Labels have limited visible space and long text can end in an ellipsis. Use short prompts instead of full paragraphs, review the map at a readable zoom, and open the PNG to check the result. Zoom changes your preview scale, not the amount of text the label can hold. On a small screen you may need to pan the preview or use Expand.
Can I use this for homework or revision?
Yes. Study provides an exam-review starter, and the writing example can guide a class outline. Check your sources and assignment requirements yourself. Editing and standard PNG download need no account; check the resulting image on your device before submitting it.
Which exports are free?
Standard PNG download is free without signup or a watermark. SVG, HD PNG at 2×/3×/4×, and MP4 use Pro access or an active export pass. This tool does not have a direct PDF download. Downloading a PNG gives you an image, not a saved editable map.
How do I reopen an editable map later?
Use Save and sign in when prompted. Free accounts can keep up to three saved designs. Use Open saved designs to reopen one. Downloading an image alone does not save the editable design to your account.
