Hi HN,

I’m Rem, a solo founder, and I just launched Lumail (https://lumail.ai) – an autonomous AI agent that lives in your Gmail inbox. It reads full email threads, pulls in context from your past conversations, checks your Google Drive files or uploaded docs, and takes action: labels emails, drafts replies, or skips when it makes sense.

Why I built it? I was tired of manually handling repetitive support and operations emails – tracking orders, answering the same questions, digging through past threads. I didn’t want an assistant I had to prompt. I wanted an agent that understood context and acted on its own.

What it does:

- Monitors your Gmail inbox using official OAuth - Reads entire threads to understand context before acting - Uses your Google Drive docs or uploaded files as its knowledge base - Drafts smart, customizable replies using with your prompt logic - Applies/removes labels to organize inbox as needed - Works autonomously in the background, with full auditability - Learns your writing style and tone

It’s a decision-making agent built for operators, founders, and support-heavy teams. You can fully customize prompts and see exactly what the agent does before sending anything.

I'd love to hear your thoughts and feedback!

Thanks for checking it out!

tl;dr - agents from ustda.ai are coordinating with agents from usitc.ai and produced https://github.com/HardisonCo/.github/blob/main/MONEYBALL_BU... ...

Note: About 1 month of context and pipeline stuff missing from here, but still interesting IMO

I just got an email from VPNSecure saying that my account was deactivated (not that it will be). They (I don't know who) bought the company, but the previous owner didn't disclose the number of subscribers that were not paying for the service.

Here is a screenshot of the email:

We’ve built a functional prototype for an operating system layer that rejects the classic trust model.

Every process, network access, and system action is explicitly scope-bound to a signed capability token (CapToken) – backed by a cryptographic wallet and domain-specific responsibility structure.

Key Components: CapToken authentication for all system actions

CapAuditDaemon (feedback, incidents, signed system state)

Feedback replaces control – the system acts on effect, not permission

CapNFTs as soulbound responsibility certificates

VPN routing via chain-verified nodes (CapVPNRegistry.sol)

Whitebook & mathematical formalization published on Zenodo

No ACLs, no root, no anonymous processes. Only signed, trackable responsibility. Period.

GitHub: https://github.com/Xtothepowerofinfinity Docs/Whitebook: https://zenodo.org/communities/xtothepowerofinfinity

Feedback kills control. Power demands responsibility.

Hey guys, I'm a CS student who loves reading technical books and papers but I realized I was reading really passively. I'd fly through dense material, feel like I understood it, and forget it all within a few pages.

I finished OSTEP less than a week ago and already struggle to recall how locks are implemented. That's why I built Readspace to stop passively reading and finally make the knowledge stick.

It’s an ebook reader with built-in active recall that prompts me every couple pages to explain what I just read. I can respond using the Feynman technique or engage in Socratic-style questioning, and the AI grades my answer and helps you refine it step by step. I wanted an SRS system that actually felt good to use—so I built one directly into the reading flow. The flashcards are AI-generated from what I find important, and they’re scheduled using FSRS.

Readspace has honestly made my reading 10x more meaningful. I’ve stopped cramming for classes because I finally have a systematic setup to learn efficiently.

Would love some feedback or advice—this is the first serious project I’ve shipped!

Hey all,

I built Interview-Guru, an AI-powered mock interview tool that helps you practice crafting a story, organizing your thoughts, and improving with feedback and examples — all through real-time voice conversations.

Having always struggling with the behavioral portion of the interview, I have found that most new AI tools were either push-to-talk or purely text-based, which adds too much friction to realistic practice. I wanted something that feels like you're talking to a real interviewer — natural, responsive, and pressure-tested.

Interview-Guru covers a wide range of behavioral and situational questions across different industries and roles. It listens, analyzes, and gives actionable suggestions on how to strengthen your responses.

So I have been working on this side-project for awhile, but only felt possible recently with how far stt, tts, and LLMs have come.

You can try it out at interview-guru.io/playground. Working on new features/bug fixes and would love any suggestions or feedback in the comments.

Thanks!
