An ultra-fast canvas that stays calm
Trace every cause behind
the problem you are solving.
Storyflow is a fishbone diagram maker on a truly infinite canvas. Put the effect at the head, branch the major cause categories as the bones, and hang the contributing causes off each one, with AI to help surface the causes you might miss. When the analysis is done, turn it into an action plan on the same canvas.

What is a fishbone diagram, and how do you build one?
A fishbone diagram, also called an Ishikawa or cause-and-effect diagram, is a structured way to map every possible cause of a problem in one picture. You write the effect you are investigating in a box on the right, the head of the fish. A long spine runs to it, and off that spine branch the major cause categories, the big bones. Off each big bone you hang the specific contributing causes, the smaller bones. Read together, the diagram lays out the whole web of what could be driving the effect, so a team can see the causes side by side instead of arguing about one at a time.
Building one is a sequence. First, agree on the problem statement at the head. Next, pick the major categories, often a starting set like People, Process, Equipment, Materials, Environment, and Measurement, though you rename them to fit your situation. Then brainstorm causes under each category, asking why until each branch bottoms out at something you can actually check. Finally, look across the finished diagram for the causes that appear more than once or feel most likely, and take those into root cause analysis or an experiment.
Storyflow builds fishbone diagrams on an open infinite canvas. The head, the spine, the category bones, and every contributing cause are real cards you drag, recolor, and regroup, so the diagram bends to how the problem actually breaks down rather than snapping to a fixed template. Ask the AI to suggest causes under a category you are stuck on, pin a screenshot or incident log beside the branch it explains, and when the analysis is done, turn the diagram into a task board of fixes on the same canvas.
Ultra fast from brief to board
Build a fishbone diagram in four steps.
Start from a blank canvas or a single prompt. Either way the head, the bones, and every cause stay yours to rearrange.
01
Open your canvas
Start in the browser with a Storyflow account. Nothing to install, just an infinite canvas ready for the problem you want to break down.
02
Set the problem at the head
Write the effect you are investigating as the head of the fish, then add the major cause categories as bones, or describe the problem once in the AI chat and let Storyflow lay out the first set of bones for you.
03
Branch the contributing causes
Hang specific causes off each category bone, ask why until each branch bottoms out, and let the AI suggest causes for a category you are stuck on while the rest stays exactly as you arranged it.
04
Turn the analysis into action
Convert the diagram into a task board of fixes and owners on the same canvas, share a view-only link with the team, or export it as an image or PDF for the report.
Fishbone diagrams that lead to fixes, not just a tidy picture.
Keep the head-spine-bones structure you know. Lose the rigid template, the object cap, and the dead end where the diagram just gets screenshotted.
Bones are real canvas cards
A diagram you can actually reshape
The head, each category bone, and every contributing cause is a card you drag, recolor, and regroup. Moving a cause under a different category is one drag, not a redraw, so the analysis keeps pace with the discussion.

AI surfaces the causes you miss
Ask AI to suggest causes under a bone
Point at a category you are stuck on and ask the AI to suggest contributing causes. It reads your current board as context and adds causes that fit the problem in front of you, not a generic checklist, so the team has more to react to.
See the AI brainstorming tool →
From causes to fixes
The analysis becomes an action plan
Once the likely causes are marked, turn the diagram into a task board of fixes, owners, and checks on the same canvas. The causes carry over so you act on the analysis you built instead of retyping it into another tool.

Room for the whole analysis
An infinite canvas, no cause cap
A thorough root cause analysis sprawls across many bones and sub-causes. With a truly infinite canvas and no object cap on any plan, no branch gets cut for space and the diagram never runs into an edge.
See the free infinite canvas →Plans from $7.99/mo. No cause cap.
Storyflow is paid-only during early access. Open a canvas and start mapping causes on Plus, which has no object cap and no time limit, so a full root cause analysis never runs into an edge or pushes you to upgrade mid-session.

Built for people with taste
Built for the way problem-solving teams actually work.
Branch causes under every category, name what belongs where, and keep the whole analysis visible at once.
Structure without a straitjacket
Head, bones, and causes that move
Rename the categories: Start from a classic set like People, Process, Equipment, Materials, Environment, and Measurement, or rename the bones to fit your situation. The canvas never forces a fixed template.
Drag causes between bones: A cause you filed under Process turns out to be about Equipment. Move it with a drag, and the diagram reshapes with the discussion instead of a rebuild.
Color the likely causes: Recolor the causes the team thinks are most probable so the leading candidates stand out at a glance across a big, busy diagram.
AI that reads the board
AI suggests causes from what is there
Fill a thin category: Ask the AI to suggest more causes under a bone that feels empty. It builds on the causes you already placed, so the additions fit the problem instead of drifting off-topic.
Bring in the evidence: Add up to five documents and three boards as context from the + menu, so an incident report, a spec, or a log shapes the causes the AI suggests.
Ask why one more time: Point at a cause and ask the AI to go a level deeper, drawing out the root behind it so a branch does not stop at a symptom.
More than text on a bone
Evidence beside every cause
Drop in anything: Screenshots, video, GIFs, PDFs, and links sit on the canvas next to the cause they document, so the evidence for a branch lives with the branch instead of in a separate ticket.
Frame grabs from video: Pull stills from YouTube and Vimeo straight onto the diagram when a recorded incident or walkthrough shows a cause better than a label can.
Notes where you need them: Longer write-ups live as documents on the same canvas, so the diagram stays scannable and the detail behind a cause is one click away.
The diagram is step one
From cause-and-effect to a plan
Turn causes into tasks: Convert the diagram into a task board of fixes, owners, and checks on the same canvas, with the AI carrying the causes you marked across.
Share the analysis: Invite collaborators free, or send a view-only link so a stakeholder or reviewer can explore the whole diagram in the browser without an account.
Export anywhere: Need the diagram in a report, a review deck, or an audit doc? Export it as a clean image or a PDF in one step.
Explore templates for your project
Every template opens as a real, editable board on the infinite canvas. Pick the closest fit and make it your own.

How Storyflow compares to other fishbone diagram tools.
Plenty of tools draw a neat fishbone. The question is whether AI helps surface the causes and whether the diagram turns into a fix.

Fishbone diagram questions, answered.
Everything people ask about making fishbone diagrams in Storyflow.
A fishbone diagram maker lets you map the causes of a problem as branches off a central spine, with the effect at the head and the major cause categories as the bones. Storyflow does this on an infinite canvas where the head, every bone, and every cause is a real card you can move, edit, and regroup, rather than a fixed auto-arranged template.
They are the same thing. The fishbone diagram was developed by Kaoru Ishikawa, so it is called an Ishikawa diagram or a cause-and-effect diagram interchangeably. All three names describe the same head-spine-bones layout for mapping the causes behind an effect, and Storyflow builds it the same way whatever you call it.
Not during early access. Storyflow is paid-only right now, with Plus starting at $7.99 a month billed annually, and a Free plan is planned before the end of 2026. Every paid plan includes unlimited diagrams, basic AI usage to suggest and expand causes, 20 file uploads, and view-only sharing. Anyone a paid member invites to a board joins free.
A common starting set is People, Process, Equipment, Materials, Environment, and Measurement, but the categories are yours to rename. In Storyflow each bone is a card, so you can swap in categories that fit your problem, add a new one, or drop one you do not need without fighting a fixed layout.
Yes. Point the AI at a category bone and ask it to suggest contributing causes, and it uses your current board as context so the suggestions fit the problem in front of you. You can also ask it to go a level deeper on a cause to draw out the root behind it. Every suggestion is yours to keep, edit, or remove.
Both. You can start from a blank canvas and place the head, the bones, and every cause yourself, dragging and labeling as you go. The AI is there when you want it, to suggest causes under a bone or expand a branch, but the diagram is always yours to reshape.
Yes. Attach screenshots, PDFs, video, GIFs, and links to any cause, and grab frames straight from YouTube and Vimeo onto the canvas. The evidence behind a branch, such as an incident log or a photo of a defect, lives right beside the cause instead of in a separate ticket.
Yes, and that is the point of mapping causes in Storyflow. Ask the AI to turn the diagram into a task board of fixes, owners, and checks, and it builds the new board on the same canvas from the causes you marked. The analysis becomes something you act on instead of a picture you screenshot.
Stop guessing at the cause. Map it out and fix it.
Set the problem at the head, branch the causes, let AI surface the ones you miss, and turn the diagram into a plan.
