Strengths and limits
Preuve AI
Strengths
- One-time pricing: Founder products are single payments with no subscription, and Sentinel does not renew or charge after three months.
- Claims link to sources: The vendor says sourced claims link back to their source and estimates are labelled as estimates.
- Free first check: The Reality Check gives a score, market size and two competitor previews for 2 scans with no payment.
Limits to plan around
- Score method is closed: Factor weights, thresholds and agent prompts are unpublished, and the vendor says the score is a snapshot, not a guarantee.
- Narrow free tier: The free check is limited to 2 scans, each viewable for 7 days, with 2 competitor previews and no pivots.
- Narrow refund: The 14-day guarantee is a rerun first, once per customer, and not after Build with AI or an export; Lifetime plans and the Investor Package are excluded.
Consensus
Strengths
- Large research index: Answers draw on a search of more than 220 million peer-reviewed papers, per the pricing page.
- Fine-grained study filters: Filters for study design, population, sample size and journal rank, plus a preprint switch, narrow results before you read.
- Reference-manager exports: Search results export to CSV, RIS or formatted bibliographies, and Deep reports export to PDF.
Limits to plan around
- Abstract-only evidence: When full text is unavailable, a cited paper may have been read from its abstract alone, so methods and caveats can be missing.
- Small Free allowance: Free has up to 3 Deep reviews monthly, each also consuming a Pro message. Official Pro-message allowances differ; confirm the available count in account settings.
- Team prices not listed: The Team and Enterprise tab of the pricing page shows no amounts; larger licenses are quoted by sales.

Comparing tools from different categories is fine, and often useful — a writing assistant and a research tool solve different halves of the same job. The table will show you exactly where they diverge.
Questions about comparing tools
How does the comparison work?
Add two tools to the comparison tray from any tool card, then open this page. The table pulls each tool's verified plan details, platforms, strengths and limits from its profile, so both columns carry the same kind of evidence, with a separate source-check date for each tool.
Do you declare a winner?
No. The table sets two tools against each other on documented facts, not on a score. Which one wins depends on your task, your budget and your usage volume — three things we cannot see from here.
Why are some cells empty or marked unverified?
Because we could not confirm that detail on the vendor's own pages. Rather than filling the gap with a figure from elsewhere, we mark it and say why on the tool's profile.
Can I compare more than two tools?
Not at once. Two columns keep the differences readable and force a real decision. Remove either selected tool to replace it, or clear both to start a new pair.
Every figure in the table above comes from the linked profile, where the source and the verification date are listed. Browse all tools or read the editorial policy.
