Overview
<p><b>Description</b></p><p>Our AI-powered transcription bot converts voice notes from messaging apps into text, with a primary focus on WhatsApp integration. Founded in 2021, we solve a common pain point: receiving voice messages when listening isn't convenient or possible. Users simply forward audio messages to our bot within WhatsApp and receive accurate text transcriptions within seconds, allowing them to read messages at their convenience whether they're in meetings, noisy environments, or multitasking.</p><p>With 4 years of consistent cash flow and 950,000 downloads through organic growth, our service has proven market fit and sustainable demand.
