Alongside the investigative systems, I build and ship small, focused tools — the kind that do one thing properly and then stay out of the way.

— type less, say the same. Type a short abbreviation in any app and it becomes the phrase you saved: a signature, an address, a reply you send ten times a day. Dates, the clipboard, fields that ask you once and real key presses; Turkish characters come out exactly right. Your phrases stay on your computer; no account, no network.
macOS 12+ · Windows 10+ · Microsoft Store · Mac App Store coming soon · free, no analytics
macOS & Windows · Mac App Store & Microsoft Store soon
— your GitHub pull requests in the Mac menu bar or the Windows notification area: the ones you wrote and the ones waiting for your review, their CI down to the GitHub Actions step that is running, and a notification when CI finishes, a review lands or someone asks for yours.
macOS 15+ · Windows 10 & 11 · Mac App Store & Microsoft Store coming soon · no analytics
macOS · Safari extension · Mac App Store
— a pixel-art Safari new tab with your most visited sites, a world map that changes with time and weather, a focus timer, tasks and a post-it note. Future visits count by domain after you grant website access; your private iCloud can sync sites and focus data.
macOS 26+ · Safari · Mac App Store · no ads or analytics
macOS · Safari extension · Mac App Store soon
— long pages, side by side. Any long page in Safari laid out in columns that read as one ribbon: the second column continues where the first ends, and one scroll moves them all. Main hides sidebars and banners; feeds keep loading and can be shown as clean cards.
macOS 26+ · Safari · Mac App Store coming soon · English and Turkish · no data collected
macOS · Mac App Store
— see what your notes know. A folder of Markdown or text — an Obsidian vault included — drawn as a map: notes that mean similar things sit together and are joined, whether or not you ever linked them, and each group carries the name of what it is about. Search by meaning and by the words at once; write a new note where you are reading.
macOS 26+ · Apple silicon · Mac App Store · English and Turkish
macOS · Mac App Store
— a writing editor for Turkish and English that marks sentences that read as machine-made, explains why, and helps you rewrite them in your own voice: readability and style metrics, spelling and style findings through lenses, and on-device rewriting with Apple Intelligence. No account, no network.
macOS 26+ · Apple silicon · Mac App Store coming soon · English and Turkish
iOS and macOS · App Store · free
— the logic puzzle with no words. A row of shapes and a few rules drawn as pictures; exactly one order fits them all. Every move is marked deduced, lucky or wrong, so the line you share shows how you think and gives nothing away. One puzzle a day, a 200-level campaign that teaches by showing, and endless levels proved fair before you see them.

macOS · Mac App Store
— what happened on this Mac? Ten columns on one time line: apps installed, USB and Bluetooth devices, networks, downloads, logins and sleeps, crashes, permissions granted, system events, terminal commands, app usage — read from the logs macOS already keeps, every event with its evidence. No upload, no network, no verdict.
macOS 26+ · Apple silicon · Mac App Store · English and Turkish
macOS & Windows · Mac App Store & Microsoft Store
— what does the picture file say? Drop an image and read the evidence: metadata and its contradictions, Content Credentials, compression, error-level and noise maps, repeated regions, AI and screenshot marks, every hash. One sentence per finding, never a real/fake verdict. No network at all; nothing leaves your computer.
macOS 26+ · Apple silicon · Windows 10+ · Mac App Store · Microsoft Store · English and Turkish
macOS · Mac App Store
— a song analyser for songwriters and producers. Drop a song on the window and get a report: key and chords, tempo and rhythm, form and energy, lyrics and hooks, and where each sits against 68 years of chart hits. It explains; it does not predict. There is no score. Everything runs on the Mac; nothing is uploaded.
macOS 26+ · Apple silicon · Mac App Store · English and Turkish
macOS · Mac App Store
— a menu bar app that keeps a MacBook's battery between two limits by switching the charger's smart plug. Lithium cells age fastest sitting at 100%; AutoBattery cuts the power at the outlet when you reach your upper limit and restores it when you drop to the lower one. Not a software charge limiter — the draw is genuinely zero.
macOS 15+ · Apple silicon and Intel · Mac App Store · TP-Link Tapo required
macOS · Mac App Store
— a local-first forensic investigation workspace for evidence, timelines, graph context, rules, and defensible findings. Use the embedded server on your Mac or connect to an FGIT server you operate.
macOS 13+ · Apple silicon and Intel · Mac App Store · optional self-hosted server
macOS · Mac App Store
— a native presentation studio for building, editing, narrating, and rendering lessons on Apple silicon. Projects stay local by default, with explicit controls for cloud AI, media import, and external project folders.
macOS 14+ · Apple silicon · Mac App Store · no analytics
macOS and Windows · Mac App Store · Microsoft Store
— a focused CSV viewer for opening, filtering, and sorting local data. Files stay on your computer; there is no account, upload service, or analytics SDK.
macOS 13+ · Apple silicon · Windows 10+ · Mac App Store · Microsoft Store (free) · local-only
macOS, Linux & Windows · direct purchase
— a licensed forensic investigation toolkit for analysts who need repeatable collection, parsing, triage, and reporting workflows without a vendor cloud account.
One-time license · $150 · five active devices · online activation · local-first
macOS · Mac App Store
— a private clipboard manager for keeping copied text, links, code, and sensitive values close at hand on your Mac.
macOS 14+ · Apple silicon · Mac App Store · local-first · encrypted storage
iOS & iPadOS · App Store · free
— a calculator for combined impairment rates. Rates do not add up: each one applies to what the ones before it left whole, so 25.5% and 12% combine to 34.44% rather than 37.5%. Every rate is set on a wheel, so there is nothing invalid to type, and the working is shown step by step.
iOS 17+ · iPhone and iPad · App Store · free · offline · six languages
macOS & Linux · direct download · free
— a command line sender and a native macOS menu bar receiver for a self-hosted ntfy server. Push a line from any script — a finished backup, a completed deploy — to your Mac's notification centre, through a server you run yourself rather than a commercial push service.
macOS 13+ and Linux ARM64 · direct download · free · signed and notarized
macOS, Windows & Linux · direct download · free
— a command line tool that finds duplicate files by content, not filename. Scans a folder tree, verifies matches with a content hash, and reports before touching anything — delete or hardlink the copies only when you ask it to.
macOS, Windows and Linux x64 · direct download · free · single binary
macOS & Linux · direct download · free
— record a real terminal session, including what you type, and turn it into a polished MP4. Capture and render separately when a command will take a while.
macOS Apple Silicon · Linux x64 and ARM64 · direct download · free · open source
macOS · direct download · free
— one dashboard for every AI coding session on a machine. Watches Claude Code, Codex, Cursor, OpenCode and Antigravity's own session files and shows sessions, rules, skills and memory in one place, with one-click terminal launch for any of them.
