Flowchart Maker
Map a decision flow (with yes/no branches and outcomes) or a swimlane process across actors. Deterministic rendering — your labels are drawn exactly, every time.
The Gixo Prism Flowchart Maker turns a typed list of steps into a finished flowchart in one render, with no sign-up and no AI model in the loop. It builds 2 kinds: a decision flow, where each row is marked as a step, a decision, or an outcome and a decision can carry an “if No” branch drawn to the side; and a swimlane, where each row names the lane or actor that owns it and the steps are laid out left to right in numbered order. One render accepts up to 200 steps, in 4 theme presets or your Brand Kit palette. Because the layout is computed by deterministic code rather than generated, the same input always produces the same chart and every label is drawn exactly as typed. Rendering and previewing are free and anonymous; copying clean HTML, embedding, and downloading HTML, SVG, PNG, PDF, and PPTX files require an active Prism trial or plan.
Decision flow or swimlane: which one do you need?
A decision flow answers “what happens next, and what if the answer is no?”. A swimlane answers “who does what, in what order?”. Both take the same numbered rows and the same themes; they differ in the extra field each row carries and in how the result is laid out.
| Aspect | Decision flow | Swimlane |
|---|---|---|
| What it shows | Branching logic — the path through a policy or rule | Ownership — which actor holds each step |
| Layout | Single column, top to bottom, with arrows between rows | One row per lane, one column per step, left to right |
| Extra field per row | Type: step, decision, or outcome | Lane / actor name |
| Branching | A decision row takes an “if No” label, drawn as a side branch; the onward arrow is labelled Yes | None — every step continues to the next |
| Shapes drawn | Rounded box for a step, diamond-marked box for a decision, pill for an outcome | Bordered lane label plus one numbered step card per column |
| Paste format | One step per line; set the types afterwards | One step per line as Lane | Step |
| Steps per render | Up to 200 | Up to 200 |
| Starter template | Client intake decision | Workstream handoff swimlane |
| Use it when | Approvals, eligibility rules, triage, refund or escalation policy | Handoffs, onboarding, delivery workflows, RACI-style walkthroughs |
How to make a flowchart, step by step
- Pick the kind. Choose Decision flow for branching logic or Swimlane for work that crosses actors. The row fields change to match.
- Enter the steps in order. Type them into the numbered rows, or open Paste a list and paste one step per line — in swimlane mode, write each line as
Lane | Step. - Mark the decisions and outcomes. In a decision flow, set each row's type. On a decision row, fill in If No → to draw the rejected path as a labelled side branch; the onward arrow is labelled Yes automatically.
- Choose a theme. 4 presets ship with the tool — Conservative, Bold, Brand conservative (the default), and Brand bold — and a saved Brand Kit replaces the palette with your own colours.
- Render it. Press Make flowchart. The render is in-process deterministic code with no AI call, so it returns immediately and your labels are drawn exactly as typed.
- Take the file. On a Prism trial or plan, copy clean HTML, copy an embed snippet, or download HTML, SVG, PNG, PDF, and PPTX. Without one, the preview stays on screen with a “Made with Gixo Prism” watermark.
