AI Assistants (General) Feb 11

Security challenges emerge as AI agents gain real-world capabilities

MIT Technology Review explores the risks of AI agents with tools like web browsers and email access. The piece highlights how mistakes that are manageable in chatboxes become far more serious when agents can interact with the outside world. Source →

Designer's Takeaway: Design AI interfaces with clear boundaries and explicit confirmation steps for any actions that affect external systems or user data.

Pattern: Human-in-the-Loop

Vercel Flags Feb 11

Vercel launches feature flags in public beta

Vercel Flags provides a platform-integrated way to create and manage feature flags with targeting rules, user segments, and environment controls. The SDK integrates directly with Next.js and SvelteKit applications. Source →

Cart Assistant uses AI to build grocery lists from text or images

Uber Eats launched a new AI feature called Cart Assistant that automatically adds items to your cart based on text prompts or image uploads. The feature streamlines the grocery shopping process by interpreting user intent. Source →

Pattern: Multimodal Interaction

PostHog Feb 10

PostHog integrates with Vercel for embedded analytics and feature flags

PostHog joined the Vercel Marketplace as an integrated analytics and feature flags provider. This allows teams building on Vercel to test in production, reduce release risk, and make data-driven decisions within their existing workflows. Source →

Pattern: Guided Learning

Today's Takeaway

The Human Safety Net

As AI agents become more capable of taking real-world actions, the design challenge shifts from making AI helpful to making it safely helpful. The most successful AI products are building in multiple layers of human oversight, confirmation steps, and gradual capability rollouts rather than giving agents free rein.
