Voice to Text for Excel
Data entry in Excel shouldn't mean endless typing into tiny cells. Blurt lets you speak your data directly into any cell, comment, or text field. Hold a button, talk naturally, release. Your words appear exactly where your cursor is with proper formatting. Whether you're entering sales figures, adding cell comments to explain calculations, documenting complex formulas, or annotating financial reports, your voice becomes your keyboard. Works on macOS for $10/month or $99/year, with a first 1,000 words free.
The Typing Problem
Cell-by-cell data entry destroys your productivity
You have 200 rows of data to enter. Click cell, type value, tab to next, type again. Your eyes bounce between source documents and the spreadsheet. After an hour, you've made three typos you won't catch until the formulas break. Your wrists ache from the repetitive motion. The data that should take 20 minutes takes two hours because typing into small cells is painfully slow.
Cell comments never get written because typing is tedious
You know you should document why that formula uses 0.15 instead of 0.12. You should explain what that VLOOKUP is referencing. But adding comments means right-click, insert comment, type explanation, click away. By the time you've documented three cells, you've lost your flow. So you skip it. Three months later, nobody knows why the spreadsheet works the way it does.
Formula descriptions exist only in your head
That nested IF statement took you 30 minutes to write. It works perfectly. But there's no documentation explaining the logic. You tell yourself you'll remember. You won't. When someone else opens the file, they see =IF(AND(B2>100,C2<50),D2*0.15,IF(OR(B2<50,C2>100),D2*0.08,D2*0.12)) and have no idea what business logic it represents. The formula is correct but incomprehensible.
Report annotations take longer than the analysis
Your monthly report needs explanatory text in merged cells above each section. 'Q3 revenue exceeded projections by 12% due to new enterprise contracts.' You could type that in 20 seconds, but you need 15 of these annotations. By annotation eight, you're writing shorter, less helpful explanations. The report loses context because typing long text in Excel cells is awkward.
Sheet documentation becomes an afterthought
Your workbook has 12 sheets. Each should have a documentation sheet explaining data sources, update schedules, and calculation methodologies. But creating documentation means typing paragraphs into cells that aren't designed for paragraphs. The documentation sheet stays empty. New team members spend hours reverse-engineering what should have been explained in five minutes of dictation.
How It Works
Blurt works anywhere you can type in Excel: cells, formula bar, comments, text boxes, headers, footers, and documentation sheets.
Hold your hotkey
Press your chosen shortcut while your cursor is in any Excel field. A small indicator shows Blurt is listening.
Speak your content
Talk naturally. Dictate data values, comments, formula explanations, or full paragraphs of documentation. Blurt handles punctuation automatically.
Release and continue
Text appears at your cursor. Tab to the next cell, move to a comment, or continue in the same field. No extra steps required.
Real Scenarios
Rapid data entry across multiple cells
You're entering product inventory from a physical count sheet. Click the first cell, hold your hotkey, say 'Widget A, 150 units, warehouse B.' Tab to the next row. Hold, speak. 'Widget B, 87 units, warehouse A.' Each entry takes 3 seconds instead of 10. Your eyes stay on the source document. You finish 200 rows in 20 minutes instead of an hour. No typos from fat-fingering tiny cells.
Adding explanatory cell comments
Your budget spreadsheet has dozens of assumptions. Right-click cell B7, insert comment, hold your hotkey and say 'This rate assumes a 3 percent annual increase based on historical data from 2020 through 2024. Verify with finance if market conditions change significantly.' A detailed, useful comment in 5 seconds. Your spreadsheet becomes self-documenting without slowing you down.
Documenting complex formulas
You just wrote a formula that calculates tiered commission rates. In the adjacent cell, hold button and speak: 'Commission calculation: 8 percent for sales under 50k, 12 percent for 50k to 100k, and 15 percent for sales exceeding 100k. Uses nested IF statements to evaluate thresholds in order.' Future you and your colleagues will understand the business logic without deciphering the formula syntax.
Annotating financial reports
Your quarterly report needs narrative context. Click the merged cell above the revenue section, hold hotkey: 'Revenue increased 18 percent year over year driven primarily by expansion in the northeast region. Enterprise contracts contributed 2.3 million in new recurring revenue.' Professional annotations appear instantly. Your reports tell a story, not just show numbers.
Creating sheet documentation
Your workbook needs a README sheet. Click cell A1, hold button: 'Data Sources: This workbook pulls from three systems. Column A through D come from the CRM export dated the first of each month. Column E through H come from the billing system API. Column I onward contains manual adjustments documented in the comments.' Comprehensive documentation in 15 seconds of speaking.
Entering text-heavy data like addresses
You're building a customer contact list. Each row needs full addresses. Hold, speak: '1425 Industrial Boulevard, Suite 300, Chicago, Illinois, 60614.' Tab to phone number. Hold, speak: '312-555-0147.' Text data entry becomes as fast as numeric entry. No more hunting for special characters on the keyboard.
Writing notes in shared workbooks
Your team collaborates on a shared Excel file. You need to leave context for the next person. In the notes column, hold button: 'Updated pricing as of December 2025. Old rates archived in the Previous Rates sheet. Contact Maria in procurement if vendor changes pricing again.' Team communication happens inline without switching to email or chat.
