Can ongoing research replace a validation report?
It can answer some of the same questions, but the deliverables and methods need comparison. Tallis does not claim to reproduce Preuve’s validation method or scoring. [1]

| Work to hand over | Recurring research, drafted communication and controlled upkeep of existing accounts and sites. [T] | An assessment of a business idea using research. [1] |
| Control over actions | Exact previews in Preview mode; policy-based Guardrails and Autopilot, with pause and records of outcomes. [T] | External action controls not established by this review. [1] |

Which fits you?
Start with your
next useful task.
Consider Preuve for a packaged evaluation of a new idea. Consider Tallis for continuing competitor briefs and research connected to your own priorities. Neither a favorable report nor an assistant answer substitutes for evidence from customers.
This is our assessment of fit. We have not run a head-to-head performance or reliability test.
Try this before deciding
A useful test beats
a feature count.
Suggested evaluation steps, not a test we have performed.
- State the assumption that would make you abandon the idea.
- Check whether the research addresses that assumption with traceable evidence.
- Plan a small customer test rather than treating a score as proof of demand.

Tallis’s planned offer
Tallis is being built for a solo founder or operator: private ongoing context, included model access, recurring research, and controlled actions in connected accounts. Telegram and a web chat are the launch channels. Preview requires an exact preview and approval. Guardrails and Autopilot use the permissions you set; every mode retains pause and records of outcomes.
Access is currently by waitlist. These launch intentions are not a claim that every workflow is available today. Shared teams, an app-builder marketplace and unrestricted purchases are outside the initial offer. See Tallis.
