WELCOME
Happy Tuesday, legends. Welcome back to another edition of The Frontier — our weekly newsletter covering the best new AI launches on Product Hunt.
Five AI tools you may have missed
Persona.js — The first AI chat library to natively support WebMCP, the new standard Chrome just shipped for letting agents use a website's own tools. Drop it into any existing site (WordPress, Shopify, a 2018 Next.js app) and an agent can act through your real UI instead of a clumsy headless browser. From Runtype, MIT-licensed.
PMB — Local-first memory for coding agents, from solo engineer Oleksii Bondar. It keeps your decisions, rules, and dead-ends in one SQLite file on your disk and feeds them back to Claude Code, Cursor, or Codex before each session, so you stop re-explaining your project every morning. No cloud, no API keys.
VisibAI — Tells you whether ChatGPT, Perplexity, Claude, and Gemini actually name your business when someone asks for a recommendation, then hands you a fix list (schema, robots.txt, FAQ files). Founder Francesco built it after watching buyers move from Googling to just asking an assistant.
Akiflow — The task-and-calendar app added an MCP integration, so you can run your schedule straight from Claude, ChatGPT, or Cursor: ask them to block your week, add tasks, or review your day, and connect more than one calendar at last.
Cursor for iOS — Cursor put its coding agents on your phone. Kick off a task on your Mac and keep steering it from the app while you're out, part of the steady drift of agents off the desktop and into your pocket.

Are you really still typing?
Full disclosure: Wispr Flow is the AI dictation tool most of us at Product Hunt use (we still have a few holdout typers, the romantics).
Hold a key, talk, and clean text drops straight into whatever app you're already in — Slack, email, Notion, your IDE, wherever your cursor lives. No switching windows. No copy-paste ritual. Just say the thing (yes, you can whisper it) and even your most run-on sentences come out as polished writing at 4x the speed of typing.
WHAT'S HOT
Meta open-sourced an AI that types full sentences from your brain
Meta's brain-and-AI research team this week released Brain2Qwerty v2, a system that decodes whole sentences from non-invasive brain recordings, no implant and no surgery involved. It reads at 61% word accuracy on average and 78% for its best participant, where more than half of that person's sentences came back with one word wrong or fewer. Meta put the training code for both v1 and v2 on GitHub, along with the v1 dataset, so anyone can build on it.
The reason researchers are paying attention is how it gets there. Earlier brain-to-text work leaned on hand-crafted pipelines; v2 goes end-to-end, learning straight from the raw brain signal, and the jump in accuracy is the payoff. The team also says the scaling laws look promising, the polite way of saying this gets better with more data and compute rather than topping out, which is the part that turns a research demo into a direction.
There's a very large catch, and it's not the model. The signal comes from an MEG scanner, a room-sized machine that has to stay in the building and costs about as much as a house. So this is the opposite trade from Neuralink: nobody is drilling into your skull, but the price of skipping the surgery is hardware you can't take anywhere. Brain-typing you'll actually use is gated on that magnet shrinking, and that's a much slower curve than the software.
Still, the milestone is real. Non-invasive brain-to-text has spent years stuck at "barely works," and 61% with an open codebase is the first time the no-surgery path looks like it's on a curve worth watching. The keyboard is safe for a long while yet. The direction of travel is the story.
