Experiments built on PSE

Tools we build to see where PSE takes us, from mathematics and old scripts to job search and video calls. Each is free and open source (GPL-3.0) and says plainly what it is for.

Divide Reader 0.1.1 beta

Us. Them. The others. Every text draws lines between people, and now you can measure them. Divide Reader reads a website, a book or a whole archive one sentence at a time and counts how many camps the speaker builds. Five listeners hear every sentence: a friend of the speaker, a critic, a neutral reader, someone the sentence is about, and one with no context at all. Every reading the text supports is kept, so no reading gets lost to a single verdict. Compare two outlets, two authors, or one source across the years, and watch the lines move. A difference counts as a finding only when it beats the noise, so you can stand behind your numbers. It runs offline on a built-in model at no cost. If you choose a paid online model, you set the spending cap for each job and it stops there. Free and open source (GPL-3.0), for Ubuntu and Windows. Release notes

PSE Linear A 0.1.0 beta

Linear A has gone unread for over a century: the script of Minoan Crete, still silent. PSE Linear A is a swarm that works at it in the open. It gathers the evidence, uses Linear B as the one deciphered anchor, and proposes readings three ways at once: lexical, phonetic and structural. A calibration gate holds every claim to what the evidence supports, and a read-only State of Knowledge shows exactly where things stand. It will not hand you a decipherment it cannot defend. Bring your own model, online or a local GGUF. Free and open source (GPL-3.0), for Ubuntu and Windows. Release notes

PSE Math 0.1.0 beta

Mathematics advances by conjecture and refutation; PSE Math makes that loop a workbench. Build a conjecture, push the evidence for it, and refute it the moment a counterexample appears, with every move kept in a shared library and a journal you can trust. It is a quiet, local place to track what you believe, why, and what would break it, so nothing is asserted beyond the evidence. Free and open source (GPL-3.0), for Ubuntu and Windows. Release notes

PSE Riemann 0.1.0 beta

The Riemann hypothesis is the most famous open problem in mathematics; PSE Riemann lets you walk right up to it. It computes the zeta function and its zeros on the critical line to high precision, runs numeric experiments you can repeat, and seals each one with a hash and a plain-language report. A read-only vault holds what is known apart from what is merely suspected. A workbench for seeing the hypothesis, not just reading about it. Free and open source (GPL-3.0), for Ubuntu and Windows.

PSEEK 0.1.0 beta

A job search is a hundred small tasks; PSEEK does them with you. It harvests postings, drafts applications and tracks replies, with each search kept in its own workspace. Bring your own model and your own accounts. The job-search operator for people who would rather run their search themselves. Free and open source (GPL-3.0), for Ubuntu and Windows. Release notes

Psych Asistent 0.2.0 beta

Every call has a second conversation running under the words: the pause before the price, the “honestly” that arrives just when you needed a number, the delivery date that quietly moved from three weeks to eight. Psych Asistent listens for it. It sits in a slim window beside Zoom, and when something does not add up, a card lights up with one short suggestion and the reason behind it: the exact words, the pause in seconds, the earlier statement it now contradicts. It never tells you someone is lying. It tells you what it noticed and what to ask next. It first learns how each person normally talks, so it flags changes, not personalities. English and Serbian, in Latin or Cyrillic. After the call you get a report with the key moments, the questions left open and what to do next time. To get started, bring your own AI: paste your Anthropic API key, or connect your AWS account for Claude on Bedrock, and add an AWS key for live speech-to-text. Your keys stay in memory and are gone when you close the app. Put on headphones, press Start and join your call. No keys yet? Two demo calls show you how it thinks. Live listening runs on Ubuntu; on Windows you get replay and analysis. Free and open source (GPL-3.0), for Ubuntu and Windows. Release notes

Endo 0.1.0 beta

One extension can see everything you type. Do you know who it sends it to? Endo does, before you install it. It reads the extension's code and gives you a privacy label in plain words: the companies that receive your data, whether it can see your keystrokes, your terminal, your credentials, and a rating from benign to critical. Obfuscated code counts against it. Inside, you get an AI assistant that reads, writes and runs code with you, and stops to ask before anything it can't take back or anything that leaves your machine. Every answer shows where it came from. Bring Claude, Mistral or Groq, or go fully offline with a local model. Your keys stay in your system's keychain. Free and open source (GPL-3.0), for Ubuntu and Windows. Release notes
