Exploratory vs PyNotebook

Testers.AI turns your iPhone into a professional QA engineer. Tap the Safari extension on any web page and AI agents immediately get to work — clicking, scrolling, filling forms, and probing for problems like a seasoned tester would. When they're done, a detailed bug report lands in the app: every issue ranked by severity, with steps to reproduce, screenshots, expected vs. actual behavior, and AI-generated fix suggestions. INTELLIGENT EXPLORATION Choose from eight exploration styles — Happy Path, Smoke, Negative, Edge Case, Scenario, Monkey, Adversarial, and Destructive — and focus the agents on what matters most: accessibility, security, performance, UX, forms, navigation, or content. The agents adapt their behavior to the style and focus you select. MULTI-AGENT TESTING Run up to several AI agents in serial across the same page. Each agent brings a different testing persona and approach, giving you broader coverage than any single pass could achieve. BATCH MODE Test an entire list of URLs in one go. Paste them in, or just describe what you want ("top e-commerce checkout pages") and let the AI generate the list for you — even by voice. Results land in a competitive comparison view so you can see which sites have the most issues at a glance. DETAILED REPORTS Every exploration session is saved to your history with: • Issues sorted by severity (Critical → Suggestion) • Agent step-by-step replay • AI summary of what was found • Hero stats: issues found, steps taken, agents used EXPORT ANYWHERE Share results as plain text, JSON, or JIRA wiki markup — ready to paste straight into your bug tracker. Copy individual issues, share full reports, or export a screenshot of the results to send to your team. ISSUES DASHBOARD The Issues tab organizes every bug found across all your sessions by domain and URL, so you can track quality trends across the sites you care about over time. BATCH COMPARE Run the same test across multiple competitors or pages, then review a side-by-side bar chart ranking them by issue count and severity. Great for competitive audits and regression checks before launch. PRIVACY FIRST All exploration history is stored locally on your device. No account required to get started. Testers.AI is built for developers, QA engineers, product managers, and anyone who cares about shipping quality software. Unlock full access with your Testers.AI account for unlimited testing and team sync.

PyNotebook runs Python and Jupyter (IPython) notebooks inside your iPhone. Open an .ipynb file, edit the cells, press Run, and the output appears under each cell the way it does on a desktop. THREE PLACES TO RUN YOUR CODE Local Python runs on the device itself, using a Python interpreter compiled to WebAssembly and bundled in the app. On-device Linux runs your code using your own Linux Emulator app, which gives you close to a real CPython shell on the phone. Remote SSH runs it on your own Mac, PC, Raspberry Pi, or Linux server. The phone stays the editor and the other machine does the work. The kernel chip in the toolbar switches between them. PACKAGES Write "!pip install pandas" in a cell to install a pure-Python package from PyPI. numpy, pandas and matplotlib download on first import and stay cached afterwards. iSH and Remote SSH run standard CPython, so pip there installs anything it can build, including packages with native code. CHARTS AND MATH matplotlib figures appear inline as images. Tap one to zoom. Markdown cells render LaTeX. EDITING Python syntax highlighting with indentation guides, and a Backspace that removes a whole indent level. Long-press a cell, or tap the More button, to run, copy, duplicate, move, or delete it. Drag a cell by its index pill to reorder it. FILES Opens .ipynb, .py, .md and .zip. A ZIP or folder of notebooks and their images imports as one project. Any notebook exports to the Files app as a .ipynb or as a plain .py script. Edits save as you type, so there is no save button to remember. PRIVACY The app collects nothing and has no analytics.
