We're the team behind ganttchart.ai, DReader, and the other products here. We build tools we want to use ourselves and keep running them after launch.
Now shipping from the trolls.dev newsstand
Studio figures as of September 2026. The journal count updates with each build; the infinity symbol is wishful thinking.
Project plans from plain English.
Describe your project in a sentence or two to generate a Gantt chart. Adjust the tasks and dates, then share the timeline with your team.
Read the Drudge Report on your phone.
DReader puts DrudgeReport.com headlines in a single column with larger tap targets. The reader is ad-free and links directly to the original stories.
Live object detection & GPS mapping from public cameras.
Thyseus detects objects in public traffic-camera feeds and plots their estimated GPS positions on a shared map. Contributors run the detection in their browsers.
Try research questions with AI personas.
Set a research question and run simulated interviews with AI moderators and participants. Review the transcripts and themes to prepare questions for real customers.
See what changed after a deploy.
Compare deploys with changes in business metrics such as sign-ups and revenue. Your team can see what happened after a release and decide what needs a closer look.
Check your PDF before it flies.
A native macOS utility that checks a PDF against exact submission limits — byte size, page count, searchable text, encryption — and safely optimizes it to fit. The original is never touched; nothing leaves your Mac.
A little context for how you feel.
A private mood journal for yourself and someone you care about. Record a mood, its intensity, and a little context, then explore your entries by time, day, place, and more. Your journal is stored on your device.
The workshop never really closes — more small, useful things are on the bench.
For the ten minutes before the meeting. For the headline without the noise. For the file that has to fit the form. For the deploy that still has to prove itself. We build small software for the exact moment it is needed — and we keep it running long after the world has moved on.
Set, struck & run under one roof — printed nightly, for anyone who cares to read it.
Editor's note
trolls.dev is a small, self-funded studio. We choose what to build and look after each product ourselves, from the first version through ongoing support. The trolls are a nod to the late nights spent doing it.

The house rules
Three of them, and always in this order.
Every product starts as something we wanted for ourselves. If we wouldn't use it every week, we don't build it.
We release small changes so we can see how people use them before deciding what to build next.
We handle the support and maintenance for every product we release. Bugs and operating costs come back to us.
There's more to the story — the six principles we work by and how this site is made.

To a person, a box truck crossing an intersection is a bigger vehicle. To a camera, it is a moving wall — a slab that erases whatever sits behind it, so three cars in the next lane simply stop existing for as long as it takes to pass. The detector didn't fail; it reported exactly the light that reached the lens. The quiet, load-bearing discipline in Thyseus is refusing to read that silence as a cleared street: a blocked view is marked unknown, not empty, and filled back in by the second camera that sees around the truck and by the track that remembers the car was there a breath ago.
New dispatches whenever the trolls learn something worth writing down.

The studio,
in five questions
trolls.dev LLC is a small, independent software studio. We make and maintain our own products, including ganttchart.ai and DReader.
No. We work on our own products and handle their ongoing support and maintenance.
Five products are live: ganttchart.ai for project timelines, DReader for reading Drudge Report on a phone, Thyseus for mapping objects detected in public camera feeds, AI User Interviews for simulated research interviews, and code-results for comparing releases with business metrics. Two more are coming soon: Preflight checks PDFs against submission limits on your Mac, and Orbit is a private mood journal for iPhone and Mac.
No. The studio is self-funded. We decide which products to build and how much time to spend on them.
