Making Dense Content Accessible
We believe everyone deserves to understand complex information, regardless of how they prefer to consume it.
Our Story
Lockin started from a simple frustration: existing text-to-speech tools just don't work for technical content. They butcher equations, skip over important details, and leave you wondering if you missed something crucial.
We built Lockin because we wanted to actually listen to research papers, technical manuals, and dense reports without constantly checking if the audio got something wrong. We wanted word-by-word highlighting to stay focused. We wanted the full content, not a summary that might miss the one detail we needed.
Today, we're building the reading experience that technical content deserves, one that respects your time and helps you truly understand what you're consuming.
What We Believe
Every Detail Matters
Summaries are convenient, but they're not enough. We believe you should have access to every word, every formula, every footnote.
Reading Should Be Enjoyable
Dense content doesn't have to be a chore. With the right tools, consuming complex information can actually be a pleasant experience.
Technology Should Adapt to You
Not everyone learns the same way. Whether you read, listen, or do both, the tools should work for you, not the other way around.
What We Do Differently
Premium Text-to-Speech
