Subvocal Startup Builds Glasses That Decode Silently Mouthed Words Into Text

Two founders from Georgia Tech, Aarush and Arnav, have developed smart glasses that convert silently mouthed words into text on a computer. The idea grew from frustration at being unable to use voice tools in libraries, offices, or public spaces. After a 2025 hackathon prototype using facial electrodes proved impractical, the team switched to radio frequency sensing, with antennas embedded in the glasses frames. Their foundation models were trained on data gathered from paid participants wearing the glasses, which improved performance across different users. The company, The Subvocal Company, is part of Y Combinator's F26 batch and raised pre-seed funding from Afore Capital.

Momentic Launches AI Agents That Test Web and Mobile Apps by Exploring Them

Momentic, a Y Combinator W24 startup, has launched QA agents that autonomously plan, explore, and bug-bash web, iOS, and Android apps to surface defects. Its founders, both former engineers from companies like Robinhood and Retool, built the tool to replace the brittle, hand-maintained scripts typical of Playwright and Selenium. The company's custom agent harness, called Mo, uses a self-organizing graph of parallel sub-agents, each running its own browser or device. In a 60-minute benchmark across four open-source apps, Mo found 269 bugs with 84% precision, far more than Codex's 86 bugs at 86% precision, though at a higher cost per bug.

Salesforce Screen Flow Data Tables can now display Apex collections without a custom object

Starting with Winter '26 (API 65.0 and later), the Screen Flow Data Table accepts a collection of an Apex-defined type as its Source Collection. Developers designate a field as the Unique Identifier, which lets the table treat each item like a record that users can select and the flow can reuse. Display and row selection are supported now, but inline editing is not yet available. Previously, developers had to create mirror custom objects, insert and delete temporary records, use Transform elements, or build custom Lightning Web Components to achieve this. The article outlines the setup steps, including @AuraEnabled fields, an invocable wrapper class, and key selection guidance.
