Voice to Text for Lucidchart
Typing breaks your diagramming flow. Whether you're labeling flowchart steps, annotating process diagrams, or documenting system architecture, switching from visual thinking to typing slows you down. Blurt lets you speak directly into Lucidchart. Hold a button, say what you want to type, release. Text appears instantly at your cursor. Your hands stay on the mouse, your mind stays on the diagram.
The Typing Problem
Labeling flowchart steps interrupts your visual thinking
You've mapped out the perfect process flow. Now each shape needs a label. 'Customer submits request', 'System validates input', 'Manager reviews and approves'. Every label requires switching from spatial arrangement to text entry. An hour of typing for 30 minutes of diagramming. The momentum you had laying out the flow disappears into keyboard work.
Decision point descriptions take forever to type
Your flowchart has 12 decision diamonds. Each one needs a clear yes/no question. 'Is the order value greater than $5,000?' 'Has the customer passed credit check?' Typing out detailed decision criteria while keeping track of your logic flow splits your attention. By the time you've finished typing, you've lost the thread of the process.
Process documentation becomes a dreaded afterthought
The diagram is done, but now comes the annotation. Notes explaining why this step exists, what happens in edge cases, who owns each handoff. You know exactly what to write, but the prospect of typing paragraphs of context makes you procrastinate. Documentation quality suffers because typing is exhausting after a full day of diagramming.
Swimlane labels and role descriptions pile up
Your cross-functional diagram has eight swimlanes. Sales, Marketing, Engineering, Legal, Finance, Operations, Support, Leadership. Each one needs a label plus a brief description of responsibilities. That's 16+ text entries before you've even started on the actual process. The setup work drains your energy for the real thinking.
System architecture annotations require technical precision
You're documenting your microservices architecture. Each service box needs a name, brief description, and key endpoints. 'User Authentication Service. Handles OAuth2 and JWT token generation. Endpoints: /login, /logout, /refresh.' Technical accuracy requires careful typing. One typo in an endpoint name and the documentation is wrong.
How It Works
Blurt works anywhere you can type in Lucidchart. Shape labels, text boxes, comments, annotations, and document titles. If there's a cursor, Blurt works.
Click into any text field
Shape label, text box, comment, swimlane header, or document description. Anywhere you'd normally type.
Hold your hotkey and speak
Press your chosen shortcut and say what you want to type. Blurt handles punctuation automatically.
Release and continue diagramming
Text appears instantly. No delay, no extra steps. Your hands never left the mouse.
Real Scenarios
Rapid flowchart labeling during process mapping
You're mapping the customer onboarding flow with stakeholders in a live session. Shapes are flying onto the canvas. Click into the first step, hold your hotkey, say 'Customer completes registration form and submits for review.' Next shape. 'System validates email address and sends confirmation link.' You're keeping pace with the discussion instead of falling behind on typing.
Decision diamond descriptions with full context
Your approval workflow has complex decision logic. Click the diamond, hold and speak: 'Is the purchase order amount greater than ten thousand dollars and requires VP approval?' Clear, complete decision criteria captured in seconds. No abbreviations because you were trying to type faster.
System architecture documentation
You're documenting your API gateway setup. Click the component box, hold your hotkey, say 'API Gateway handles rate limiting, authentication, and request routing. All external traffic enters through this single point. Supports up to ten thousand requests per second.' Technical documentation that's actually thorough.
Swimlane headers with role clarity
Your cross-functional diagram needs clear ownership. Click the swimlane header, hold and speak: 'Engineering Team. Responsible for technical implementation, code review, and deployment. Escalation point for all technical blockers.' Role definitions that eliminate confusion about who does what.
Process annotations for edge cases
You need to document what happens when things go wrong. Add a text box, hold your hotkey, say 'Exception handling: If payment processor returns timeout error, retry up to three times with exponential backoff. After third failure, route to manual review queue and notify customer via email.' Edge cases documented before they're forgotten.
Database schema annotations
You're diagramming your data model. Click the table, hold and speak: 'Users table. Primary key is UUID. Indexes on email and created_at for query performance. Soft delete implemented via deleted_at timestamp.' Technical precision without the typing tedium.
Network topology descriptions
Your infrastructure diagram needs context. Click the component, hold your hotkey, say 'Load Balancer. Round-robin distribution across three availability zones. Health checks every thirty seconds. Automatic failover if primary region goes down.' Infrastructure documentation that's actually useful to the ops team.
Why Lucidchart users choose Blurt over built-in dictation for diagramming work
| Blurt | macOS Dictation | |
|---|---|---|
| Activation | Single customizable hotkey | Double-tap Fn or click microphone |
| Response time | Text appears in under 500ms | 2-3 second delay, sometimes fails silently |
| Technical terminology | Handles 'API', 'OAuth', 'microservice' correctly | Struggles with technical and architecture terms |
| Workflow integration | Works without disrupting Lucidchart focus | System UI appears, breaks concentration |
| Reliability | Consistent transcription quality | Inconsistent, requires retries |
