Software reviews
with receipts.
We install every app on a clean machine, run the same scripted tests and publish the log, the timings and the scores — then let you re-rank them by what matters to you.

Latest hands-on reviews
Tested Oct 28 DiaSituational 6.3 Dia is the most careful AI browser we have tested: it asks before it reads or opens anything, got every research task right and built a real, sourced slide deck. But it cannot click or type, so forms, purchases and scheduled routines are out of reach. Read the review → 
Tested Oct 28 CometSituational 5.2 On the Free plan Comet is a fast, well-behaved Chromium browser with a quick answer panel, but not an agent: in eight scripted web tasks its Assistant never once clicked, typed or opened a tab, and every answer pointed us to Perplexity's separate Computer agent instead.

Tested Oct 28 StrawberrySituational 6.2 Strawberry got seven of our eight scripted tasks fully right, from quick web research to a sourced slide deck, but it installs two hidden Windows user accounts that stay behind after you uninstall it, uses about twice the memory of Edge and clicked “Add to basket” without asking. Capable agent, worrying footprint. Read the review → How a score is made
Every score is earned on the bench.
Other review sites tell you an app is “easy to set up”. We install it on a clean PC, run the same tasks every competitor ran, write down what happened and only then add up a score. Here is how, with a real result.
- 01
A clean machine
Every app is installed on a fresh Windows 11 virtual machine restored from the same snapshot. Nothing from the last test is left behind.
- 02
The same script
All apps in a category run identical tasks, pasted word for word, with answers we collected before the test so results can be graded.
- 03
Measured and logged
Each step is timestamped and screenshotted. We record time, cost, memory, prompts and anything the app leaves on your PC.
- 04
A weighted score
Each axis is scored from 0 to 10 and combined with fixed, published weights. Apps that have not finished the script get no score.

Things you only learn by installing it.
None of these are in the vendors’ marketing. Each one comes straight from our test log, with the screenshot to prove it.

Not your usual review site.
Most “best software” lists are written from feature pages and press screenshots. We would rather install the thing, run it through the same tasks as its rivals and show you what happened.
Our editorial rules- Screenshots Vendor press images Taken on our own test PC
- Scores An editor’s impression Same script, fixed published weights
- Evidence Rarely shown Timestamped log for every test
- Untested apps Often ranked anyway No score until tested
- Affiliate links Can sway the order Never change a score or rank
