Software advice expires.

Know what to keep, why, and what would change the answer.

Each verdict is judged by Muse Spark and carries its evidence, source and date.

Ask from any agent real response from the database

Agents ask first. Then they recommend.

Before an agent recommends software, it calls get_verdict and gets a dated, sourced answer for its user's seat.

    How it works
    
Questions a skeptic asks.

    

      
What does AirStack do?
It remembers why you keep paying for a software tool, watches that reason, and tells you the day it stops being true, with the source, the date and the condition that would change the answer.

      
How does AirStack know a verdict expired?
Every verdict stores the facts it rests on and the condition that would change it. When a source publishes a fact that meets that condition, the verdict is marked lapsed before anyone re-judges it. Muse Spark then re-checks it against the evidence, and a failed check never refreshes the date.

      
Why did two seats get different answers about Fireflies?
On 2026-08-13 Google announced in-person notes for Meet, starting on Android, so an English, Android, Business Standard seat is now covered. Meet doesn't list Hindi and takes one language per meeting, so a seat that mixes Hindi and English still needs a separate tool.

      
Is this live data?
The facts are real and linked to their sources (Google, Fireflies, 9to5Google). The page is a snapshot of the AirStack database, regenerated on every deploy. The two seats are example inputs, and judge calls marked “fixture (no model call)” are recorded responses, not Muse calls.
