Drift is a journal app for people who want less. 120 characters. A drawing and a photo. That's it. No streaks, no AI, no ads. Everything you write naturally softens over time. Text loses clarity. Drawings dissolve. Photos grow faint. Touch and hold to bring any entry back. Nothing is deleted — just quieter. Anchors is an anonymous shared space. A prompt appears periodically. Strangers respond side by side. No profiles, no followers.

Every LLM hallucinates. They just don't hallucinate the same things. Sup AI runs multiple LLMs (out of 339) in parallel, then synthesizes answers by measuring confidence on every segment. High entropy = likely hallucination, downweighted. Low entropy = likely accurate, amplified. Result: 52.15% on Humanity's Last Exam, 7.41 points ahead of any individual model. $10 starter credit. Card verified. No auto-charge.

Code Review Graph is a local-first code intelligence graph for MCP and CLI.

This dramatically reduces context overhead in code reviews and large-repository workflows, making AI tools faster and more accurate. It's built for developers and teams working in complex codebases who want to leverage AI assistance without the performance and cost penalties of massive context windows.

AutoGPT is an AI agent platform that lets you automate any workflow by simply describing what you want done.

Your titles and descriptions were probably never written to Google's spec. And the fields AI agents read (material, product details, age group, highlights, FAQ) are sitting empty. Connecting UCP Radar to Merchant Center is one click. It then works through the catalog, flagging what breaks GMC rules and what hides you from AI shopping assistants, rewriting weak titles and filling the blanks. Brand names it leaves alone. Out comes a supplemental feed Google, Perplexity and ChatGPT can read.
