Introducing Hero’s Autocomplete SDK
Hero, a productivity startup created by former Meta employees, unveiled a new autocompletion SDK that automatically fills in AI prompts based on user context. The SDK is currently invite‑only, allowing developers to embed the technology directly into their applications.
How the SDK Works
When a user begins a query—such as typing “Book a flight”—the SDK begins populating relevant fields like “to,” “from,” “on date,” “at time,” “airline” and “returning on.” Users can stop the autocomplete at any point and send the query to the AI. The tool is also useful for AI‑powered image or video generators, suggesting parameters such as object, style, location, landscape and camera angle.
Industry Context and Comparisons
Hero’s approach mirrors recent developments elsewhere, such as Adobe’s Firefly app, which lets users enter keywords for mood, style and purpose when creating soundtracks. These examples illustrate a broader push toward simplifying prompt creation for AI‑driven content.
Founder Insights
Hero engineer Saharsh Vedi noted that users typically “usually need a lot of back-and-forth with an AI app to get the results you want.” Co‑founder Brad Kowalk told TechCrunch that the company uses a series of models to predict the next input a user might type. He explained, “With AI autocomplete, we pull forward all the inputs needed to complete an action, finishing it 10 times faster as there are fewer back-and-forths involved.” Kowalk added that this “unlocks a whole new set of use cases ranging from travel to commerce, and ads to customer support.”
Technical Motivation
The founders, Brad Kowalk and Seung W. Lee, built the technology based on their experience developing AR features at Meta. Because AR glasses have limited screen space, they recognized the need for a simple interface that could add parameters to a query without overwhelming the user.
Funding, Partnerships and Future Plans
Hero raised $4 million in seed funding last year and recently secured $3 million in additional funding led by Forerunner Ventures. The company plans to raise a larger round as the SDK gains traction. Hero is testing a version of the technology within its own app to help users find time for meetings or catch up with friends via autocomplete prompts, with a public release expected in a few months. Additionally, Hero is in talks with Koah Labs, an ad‑tech startup, to develop AI‑powered ads that could surface brand suggestions within autocomplete recommendations.
Upcoming Events
The announcement was made at a TechCrunch event in San Francisco scheduled for October 13‑15, 2026.
