kelve

Kelve is a voice-only AI research assistant that won't answer for you. As you talk through what you're investigating, it searches the web (via Brave API) and suggests which pages are worth opening, but never summarizes a page. When you're done, it writes up your findings in your requested format using only the exact words and findings you spoke, linking each page you read to the related point in the text so results can be verified. Backend is written in Rust.

Chiù

Chiù is a small tray/menu-bar app for Windows and macOS that automatically prevents the computer from going to sleep while there is detectable network activity, such as a Steam game download or update. It lets users configure the activity threshold and grace period, and also offers a manual keep-awake mode. It currently ships without publisher certificates, so the OS may show a warning on first launch.

Neighborhood group-purchase and payment signup system on bunq

This tool lets organizers run collective purchase rounds with items and prices on top of the bunq bank API: participants sign up via a shared link or embedded form and instantly receive a payment request in their banking app, the organizer sees who paid and who didn't, and can refund dropouts with one click. It is also used for neighborhood event logistics such as dinner signups and collecting dietary preferences.

MCP-based intelligent email assistant

An intelligent email product built on MCP and AI agents, delivered initially as a ChatGPT app. It connects to Gmail and Outlook mailboxes (with IMAP and other providers planned later), provides a unified interface across major providers that works with any top LLM, open-source or proprietary, and derives email intelligence through transient agents powered by open-source models without ever storing emails. The long-term goal is a voice-first, provider-agnostic intelligent email service that improves over time as it builds up intelligence about the user and their mailboxes.

Ravioli

Collaborative AI companion app featuring a shared companion named Jino that you can talk to together with other people in one chat. Jino acts as a 'mutual friend' that helps couples, friends, and family understand each other, resolve misunderstandings, and stay on the same page, can plan trips accounting for everyone's inputs and preferences, and hosts games like Trivia and 20 questions.

Afrika Labs

An open speech-to-text model for Kikuyu (~8M speakers), built by fine-tuning Whisper on a cleaned 144-hour Kikuyu corpus. The first model achieves 32.9% WER / 10.5% CER, close to the published SOTA of 26% from a model 6x larger. Part of a broader effort to bring working ASR to Africa's 2,000+ languages, most of which lack it; the author also found systematic encoding corruption (mangled diacritics) in the source corpus's unscripted transcripts.
