What Vaero does
Vaero's AI produces the most human sounding writing in the world. User's input their own writing, and Vaero automatically trains custom models to write exactly like the user. It writes emails, reports, brand content, and anything else. Vaero bolts on to any existing foundation model, such as GPT-4o and Claude Sonnet 3.5, so you can always use the latest model in your writing style.

AI for Human Writing
We built an AI product that trains custom models to write in each user's exact style. Users input samples of their writing, and our platform automatically fine-tunes foundation models like GPT-4o or Claude Sonnet 3.5 to mimic their voice. It handles emails, reports, brand content, or any writing the user wants to produce. The goal is to make AI-generated text indistinguishable from human writing specific to each customer.
We live in San Francisco, CA, and Vaero is based here as well.
San Francisco gives us access to a strong AI and startup community, plus the talent pool we need to build and grow Vaero. Since both founders are here, it keeps communication and operations straightforward.
