Map out phone trees, auto attendants, IVRs, call handlers and contact center routing with real menus, hours, ring groups and queues. It lays itself out and exports clear, professional documentation your clients can read.
Add steps, connect them, tidy the whole flow with one click and export the finished document. This is the real editor, start to finish in under 30 seconds.
Call flows usually live in someone's head, a whiteboard photo or a Visio file nobody wants to update. CallSketch turns them into documentation people can actually use.
Every step looks the same and every exit is labeled, so anyone can follow a call from the first ring to where it ends. No guessing what a line means.
Consistent, polished diagrams with a title block, version and date on every page, plus a written spec of every prompt, member and route.
No placing boxes or bending connectors. Auto-arrange does the layout, templates give you a head start, and changes take seconds.
No drawing skills or training needed. If you can describe how calls are routed, you can document it: pick a step, drag an exit, type what's next.
It's vendor-neutral and works for a five-person office or a multi-site contact center. It's a drawing and documentation tool: you describe how calls route and CallSketch draws it. It doesn't connect to or read from your phone system.
Design a new phone system or a change before anyone touches the platform. Review it with the customer and agree on it first.
Keep an accurate as-built record of how every number routes, so the next person who changes it isn't starting from scratch.
Hand over a clean, easy-to-read PDF with the customer's name on every page at go-live that the customer's team can understand without a phone system background.
Real pages from a PDF export, unedited. Every page gets the title block, and the details pages spell out what the diagram can't: exact wording in each language, members, extensions and where every exit goes.
Call flows contain customer names, phone numbers, extensions and internal routing. So we built the editor to run entirely in your browser. We never receive, store or see your flows.
Designing, auto-layout and PDF export all happen on your machine. There's no cloud copy to leak.
Save flows as files wherever your company requires: your laptop, a network share, SharePoint or a ticket.
No analytics or tracking scripts. A strict browser policy blocks the page from sending data anywhere. Read the details →
Visio is a general-purpose drawing program, so every call flow means hours of placing boxes and dragging connectors. CallSketch already knows what a call flow is: menus, hours, ring groups, queues. You document it in minutes and get back to the real work.
Menus, business hours, holidays, ring groups (broadcast, hunt, round robin), shared lines, voicemail, queues, callbacks and more.
Every step comes with its real exits (1, 2, Timeout, No Answer). Drag from one, type “voicemail” and it's connected.
One click lays out the whole flow cleanly. No more nudging lines around after every change.
Title block, one diagram per page, and a written spec of every prompt, member and route. Letter to 11×17.
Keep the main line on one page and department details on others, linked with Go To steps.
Start from a main-line or contact-center template instead of a blank page.
They draw boxes and arrows. CallSketch knows how calls actually route, so a call flow is faster to build, harder to get wrong and easier for anyone to read.
| Visio / draw.io | CallSketch | |
|---|---|---|
| Building blocks | Generic boxes and diamonds you label by hand | Real call flow steps: menus, business hours and holidays, ring groups (broadcast, hunt, round robin), queues, callbacks and voicemail |
| Routing | Arrows you draw and keep attached | Every step has its real exits (1, 2, Timeout, Invalid, No Answer): drag one and type the next step |
| Layout | Nudge boxes and reroute lines after every change | One click lays out the whole flow, left to right |
| Mistakes | Nothing tells you a menu option goes nowhere | Check flags exits that go nowhere, steps nothing reaches and missing prompts |
| Prompts & languages | Text boxes, retyped for each language | Prompt wording and audio file on each step, in every language, switched with one click |
| Large systems | One huge page, or copies that drift apart | Multi-page flows linked with Go To steps |
| The handoff | A separate document for the prompts and routing | A PDF with a title block, the diagram and a written spec of every prompt, member and route |
| Starting point | A blank canvas | Main line and contact center templates |
Importing Visio or draw.io files isn't supported; starting from a template is the quickest way to redraw an existing flow.
Every plan starts with a 7-day free trial. No credit card required. Trial exports are watermarked. Prices in USD, plus applicable tax.

Every plan includes CallSketch for call flows and IVR diagrams and NetworkSketch for network diagrams. Sign in to either with the same email. No second bill.
Only on your computer. Flows are saved as files where you choose, and optionally auto-saved in your own browser so an accidentally closed tab doesn't lose work. You can turn that off. Our servers never receive them.
Your email address, your sign-in sessions and your subscription status. Payments are handled by Stripe; we never see your card number. Full details.
It's vendor-neutral: use it to document CXone, Genesys, Five9, Amazon Connect, RingCentral, Teams, 3CX, FreePBX, or anything else with menus and routing. It's a drawing and documentation tool, not a connector: it doesn't log in to, read from or change your phone system. You enter the flow (from a template, it goes quickly) and CallSketch lays it out and documents it. Start from the templates, or see contact center call flows.
Yes. Open the editor and build a flow right away; nothing to install. Saving files and exporting PDFs need the free 7-day trial (just your email, no credit card), and what you built is still there after you sign in on the same computer.
They're yours. Each flow is a plain JSON file (.callflow.json) on your computer, readable in any text editor, and every PDF you exported stays yours too. After the trial or a cancellation, opening them in the editor needs a subscription again.
Ctrl+Z / Ctrl+Y undo and redo, Ctrl+C / Ctrl+V / Ctrl+D copy, paste and duplicate, Delete removes, Ctrl+S saves, and Shift+drag selects several steps. Double-click the canvas to add a step there, or drag from any exit and type the next step's name.
No. Each subscription is for one person and can be signed in on up to two devices at a time, such as a work PC and a laptop; signing in on a third signs out the oldest. Team plans are coming soon.
CallSketch is built by a working telecom and contact center engineer who documents call flows for a living and got tired of fighting Visio to do it. It's a small, independent product: write to support@callsketch.com and the person who builds it reads and answers. See what's new.
No signup, and they run in your browser: nothing you type is uploaded.
NetworkSketch: network diagrams with media types, port labels, IP checks and a PDF title block. Included with every CallSketch plan.
