How we compare platforms
We distinguish dated supplier documents, direct company confirmations and our own analysis. Documentation tells us what a supplier says; it does not prove how the product performs. Where the evidence leaves a question unanswered, we explain what your buying team still needs to ask.
Our first choice depends on wanting help with delivery. It is not a numerical score or a claim about measured speed.
Evidence types
- Public documents
- Material that readers can open is cited with the date it was checked.
- Company statements
- Information supplied by a company is attributed and is not treated as public verification.
- Recorded observations
- Observations are included only when a dated record shows what was checked.
What this method does not cover
- Model benchmarks or hands-on performance tests.
- Legal advice or confirmation that a certification covers your particular deployment.
- One winner for every search, financial research, marketing or self-hosted development task.
What we look at
Help with the build
Who builds the workflow, and who looks after it once it is live?
Evidence requested: Ask who handles discovery, setup, testing, support and changes, and what your team must have ready first.
Your existing systems
Can this edition read and change the records your process uses?
Evidence requested: Ask to see the records and actions you need. Check sign-in, permissions, limits, custom work and who maintains each connection.
Checks you can see
Can someone show the access rules, approvals and logs your process needs?
Evidence requested: Request evidence for the exact product. Ask to see access refused, approval requested, permission removed and the resulting action traced.
Where your data goes
Where do records, model requests, outputs and logs go, and who can see them?
Evidence requested: Request a diagram of the data’s route, with hosting regions, model providers, retention rules and who gets access.
The full cost
What will it cost to start, run, change and eventually leave?
Evidence requested: Ask for an itemized proposal covering setup, software, usage, support, your own staff’s work, changes and what you receive when the service ends.
Revision log
