2019–present · independent projects
Tools for searching, learning, coding, and organizing research. These experiments grew out of related questions about how AI could work with spreadsheets, code, notes, and the web.
2022–2024
Course search for Harvard and MIT. Scraped and parsed difficult catalog data into a consistent structure, then built a fast searchable interface with filters, shareable URLs, and a custom virtualized results list. Started as groundwork for an AI domain-name search interface.
Fall 2022 · personal project
A personal calendar site for keeping track of classes, readings, exams, and deadlines. Built list and month views, course and event-type filters, expandable details, and recurring schedules that account for holidays. Included DarkReader dark mode, enabled by default and remembered across visits.
February–March 2023 · original captures February 21 and 28
A zoomable workspace for viewing and editing a codebase, with file browsing, a property inspector, console, Markdown notes, browser tabs, and chat. Original February screenshots show layers and blocks panels, a filesystem tree, console messages, chat and completion panes, and extreme zooming over long columns of text blocks. The aim was to bring browsing into a shared code-and-notes workspace, alongside experiments with code execution and coding agents.
April–September 2023 · original capture August 1
An outliner with nested and collapsible bullets, keyboard editing and navigation, and file autosave. File-reference bullets embedded a CodeMirror editor with a Save action; directory-reference bullets displayed filesystem entries inside the notes. Used as a working notes app during the Piecewise experiments, with a surviving outline of April, August, and September 2023 research and project notes.
2025
Later experiments with drawing, code execution, web search, and AI on a shared canvas. Bun Flow added draggable JavaScript, shell, and Markdown editing nodes while its execution callbacks remained unwired. Expo Code Canvas’s main app stayed at a starter screen with database experiments. A separate Expo/Bun experiment synchronized a code input with a syntax-highlighted preview; earlier web prototypes explored code alongside drawings.
December 2023–January 2024 · openai-funcs
A command-line model/tool loop with directory navigation, file reads and writes, web retrieval, and code evaluation. Original December 2023 captures show chained filesystem calls, a generated Wiktionary helper written after confirmation, retrieved dictionary material, and multilingual writing and translation experiments. A January 2024 capture shows JavaScript evaluation with user confirmation and a returned tool result. Separate experiments compared legacy completion models and personal fine-tunes on the same prompt.
2023 · prototype
CLIP embedding-based image and text search, with interpolation and arithmetic between multiple image and text embeddings. Related work included a GPU-backed batch embedding service accepting text, image URLs, and base64 images.
January 2024–2025 · earlier inspiration in 2023
A pipeline for turning scanned books into bilingual reading material: vision transcription, cleanup across lines and pages, sentence segmentation, dictionary glosses, and model-generated translations. Early 2024 interlinear.app concepts paired scans with transcribed text and a source library. The March Buber tooling exposed tokenization, sentence review, word dictionaries, and aligned glosses; August capture readers combined sentence and word translations with display toggles. Buber4 added transcription review and guarded text patches in 2025, alongside the booklet-printing tools.
November 2024 · experiment
A bilingual reading page pairing a Hebrew article about a cat show with English translations, transliteration, and word/grammar explanations. Part of the broader experiments in making unfamiliar-language text easier to read.
2024
Experiments in processing and searching long texts, including PDF intake, page rendering, and book-processing tools. The related Bible Codes work explored Hebrew and English texts, embeddings, and prayerbook reading.
2024 · prototypes
gbbl implemented semantic search across the Chumash and wider Tanakh, accepting free-text queries or a verse reference and ranking related verses by embedding similarity. Compared English, Hebrew with niqqud, Hebrew with niqqud stripped, and combined English/Hebrew representations, as well as small and large embedding models. Results appeared side by side in English and Hebrew. Daaven separately processed the Ashkenazi prayerbook and displayed Amidah sections.
2025
An etymology service using Wiktionary data and LLMs to turn wikitext into structured word histories.
2025–2026
Custom agent tools and experiments around files, images, documentation, browsers, and desktop capture. A separate browser-agent connector implemented tab listing, page interaction and extraction, a WebSocket bridge, and approval/permission flows. Recovered Chrome/macOS MCP folders also contain implementation proposals; those documents are not treated as completed tools.
Origins in 2019; apps in 2022–2023 and 2025–2026
Grew out of using Hangline as a one-person chat for notes and ideas. A personal Expo notes app that treats note-taking like a conversation with yourself. The recovered 2022 version includes local storage, search, and backup export/restore; later versions continued the focus on quick capture and data durability.
2025 · Buber4
A companion to the interlinear work, laying out Ich und Du scans and transcriptions as folded booklets for offline reading. Buber4 included page ordering, blank-page padding, adjustable print layouts, and physical-sheet and reading-spread views.
2025
Personal Chrome extensions for tab discarding and activity tracking, plus a shortcut to duplicate a tab into a new window. Tab Discarder included per-tab, per-window, and bulk actions with state badges. Tab Tracker logged browsing sessions locally. Related experiments included a browser-agent connector and a minimal extension for trying Chrome APIs from DevTools.
2026
A small viewer for exploring Hebrew roots.
2019–2024 · many internal versions
An internal browser workspace built and revised over several years, with many variants for tab and session management, text and Markdown export, searchable tables, page extraction, and AI-assisted research. The public extension is a highly pared-down version of these tools. The August 2024 Tab AI versions let users select tabs across windows, preview pages, inspect JSON/XML context, and compose a question about the selection. The February 2023 ChatRichard interface combined chat about open browser tabs with a searchable window/tab table and token/cost counters.
November 2024
Built a receipt-reimbursement workflow combining schema-validated model extraction, cached CLIP image embeddings, cosine-similarity matching, and a review interface. Structured purchase fields could be checked in a table, while nearest-image comparisons helped find duplicate receipt photographs.
July 2024 · injected browser script
A browser-injected script to make grocery browsing easier: highlight sponsored or out-of-stock items and sort by the true price. The original screenshot records the stock-status highlighting in the product grid.
March 2024
Compared Unicode characters and grapheme clusters when rendering Hebrew with niqqud and cantillation. Built side-by-side browser experiments with Intl.Segmenter, character and grapheme coloring, spacing, nested spans, and stress-marker placement to understand how segmentation and layout affect readable Hebrew text.
February 2024 · mobile prototype
A speech-to-text interview prototype for recording family stories. An AI interviewer asked follow-up questions, and recorded answers appeared in a conversational transcript so the story could be explored in more detail.
January 2024 · prototype
An Exa-based mobile search experiment with a free-text query and linked result cards. The original iPhone simulator capture shows the early search interface.
In 2022, helped Adam Aleksic with thesis research by scraping Twitter and using Google Sheets scripts and GPT-3 prompts to translate, summarize, and classify posts about Serbian/Croatian language attitudes. Genedtext explored Oxford English Dictionary research: the recovered code parses search results, while model-based result selection and full-entry extraction remained unfinished. Later experiments explored AI spreadsheets, expression-evaluating cells, and Defun: TypeScript cells that could refer to other cells’ outputs. A November 2022 Google Sheets concept demo used OpenAI calls to illustrate the workflow. January 2023 experiments paired query-focused webpage summarization with an early spreadsheet interface.
January 2023 · Piecewise prototype
Explored query-focused webpage summarization by summarizing chunks in parallel, then repeatedly merging adjacent pairs until one summary remained per page. The January 9 capture records a hierarchy reducing 28 chunk summaries to one, with token and cost logging. Another screen pairs the backend work with an early spreadsheet interface whose grid still contains placeholder cell values. The test query concerns magnesium and vision; the generated text is experimental output, and the underlying article source is unconfirmed.
Explored AI domain-name search, text and image embeddings, and image search. Coursegrep was the concrete course-search result; later Piecewise interfaces explored semantic web search and batch research.
2022–early 2023 · collaborative prototype
GPT-3 naming and domain-search experiments, followed by a collaborative full-stack prototype in early 2023. Built on earlier personal work with domain data and search interfaces.
February 2025 · prototype

November 2024–January 2025
Small TypeScript utilities for cosine similarity, Euclidean distance, and random embeddings, with tests and benchmarks. Used several package/build variants to experiment with npm publishing and Bun.
February 2025 · exploration
Wrote batched Hacker News download scripts with SQLite persistence and resume support. The accompanying sudo.surf proposal explored embedding arithmetic over links and excerpts; its recovered web server remained a Hello World scaffold.
April–September 2023 · bulk search September
A browser interface for running many web searches and reviewing results grouped by query, with titles, URLs, dates, and authors. The original September 24 capture shows bulk searches for React Native packages using the Metaphor API. Archive notes record follow-up work retrieving page contents and titles. A separate Exa parallel-search prototype followed in 2025.
Foldy was a working outliner. Smaller Hypernotes and Whispernotes variants explored note entry and organization. Transcription has not been found in the recovered Whispernotes implementation. Personal chat-shaped note experiments also included notes.chat. Note Alignment explored a Markdown-based system for organizing work, intentions, and scratch notes.
December 2022
A VS Code extension that creates or opens the day’s note with a keyboard command, using configurable folders and filenames with date placeholders.
June 2023 · prototype
A minimal note-entry interface built with Next.js: type a note, press Enter to append it, and Shift+Enter for a new line. The recovered version keeps notes in memory.
December 2022 · prototype
A small Script Kit check-in that asks what I’m doing and displays the response in a notification. Accompanying sketches explored reflection, focus, and saving workspace context.
September 2024 · prototypes
Built a browser-based directory explorer and syntax-highlighted file viewer/editor with save support. Related experiments summarized file sizes and token counts and explored notebook-style code execution. The later Code Review iterations focused on skimming a whole codebase.
September–October 2024 · numbered iterations
Built several code-review viewer iterations to make deeply nested projects easier to skim, especially folder hierarchies with only one file at each level. The interface flattened files into a list with paths, sizes, and token totals alongside a continuous, syntax-highlighted code pane. The September IDE capture identifies the fifth iteration as code-review-5; the October capture shows a starter demo project.
October 16, 2026 onward · working prototype
A macOS file viewer for skimming large archives of images, text, and code while collecting candidates for a project gallery. Built with Bun, Electrobun, and native Swift helpers: a virtualized file list, prefetched thumbnails and previews, bounded text reads, ImageIO downsampling, a persistent shortlist, multiple windows, and native file dragging. It continues the interest in fast browsing behind the 2024 code viewers and Coursegrep / Deezclasses. Embeddings and similarity grouping remain planned.
July 2020 · personal experiment
Explored few-shot translation with GPT-3 / davinci in the Playground, trying multilingual outputs, romanization, and even Egyptian hieroglyphs.
September–October 2022
Informal comparisons of matrix multiplication across Python, Node, Bun, and the browser, including CPU and GPU-backed libraries. Wrote timing and result-checking harnesses; the results were exploratory rather than rigorous benchmarks.
November 2022 · prototype
An Expo interface for displaying several model completions as they stream in. The folder was named Transformer Cellular Automata, but the recovered implementation is a completion-streaming experiment.
June 2023
Scripts for preparing personal notes as deduplicated prompt/completion training data, creating validation examples, estimating training costs, and submitting and monitoring OpenAI fine-tuning jobs.
June 2023 · prototype
A notebook-style helper that caches named code-block results across hot reloads and reruns blocks when their functions change. Recovered inside Photoviewer, whose photo-grid interface lacked a completed photo API.
June 2023 · learning experiment
Small ARM64 assembly and C exercises exploring direct execution on an M1 Mac. An early learning project rather than a finished tool.
October–December 2022 · exploration
Animated tensor-display experiments with PyTorch and PyQtGraph, alongside early neural cellular automata model sketches.
September 2024 · prototype
A web interface for running Bun code cells and inspecting execution results and captured logs, explored alongside Turing Complete. The original screenshot shows a cell inspecting the Bun runtime and rendering its returned properties.
May–August 2023
A Bun-based command-line interface for asking GPT questions from shell arguments or an interactive prompt, with response logging. The August 2 screenshot shows arithmetic, shell-command help, and generated JavaScript suggestions. This was a prompt-and-response utility, preceding the openai-funcs tool loop.
August 2024 · unfinished prototype
An Electron interface for selecting a codebase and describing desired changes. Folder selection and the analysis request were wired up; AI file analysis, graph rendering, and code changes remained placeholders.
May 2023 and September 2024 · design notes
Explored file formats mixing code, prompts, notes, and data. The later XPF (Executable Prompt Format) notes proposed frontend/backend blocks, Markdown and arbitrary tags, automatic project defaults, and editor support. Recovered as specifications and examples rather than a completed runtime.
