A side-by-side comparison built from both listings. Blank cells mean the company has not given that detail; we never guess.

QED Science compared with Cogni
Detail	QED Science	Cogni
What it does	Critical Thinking AI for constructive criticism and science evaluation	Memory that reasons
Stage	Not given	Not given
Founded	Not given	Not given
Based in	IL	US
Pricing model	Freemium	Freemium
Pricing	Not given	Free plan at $0 USD; Pro plan at $5 USD per month.
Key features	Core claim extraction and validation Grant proposal evaluation Personalized research insights feed Validity scoring and contradiction resolution SOC 2 Type II and ISO 27001 compliance Data privacy with no model training on submissions	Entity-graph spreading activation for cross-vocabulary retrieval Works with any LLM model No LLM or GPU in retrieval path Point-in-time and windowed recall Timestamped memories Fixed recall cost as memory grows
What makes it different	Only AI platform trained on feedback from thousands of domain experts including Nobel laureates User manuscripts never used for model training or fine-tuning Provides nature-reviewer-level feedback at scale Built by scientists for scientists	Reaches answers across unrelated documents that share no keywords, where vector search scores zero Deterministic retrieval with no model in the path, so results never vary between queries Constant per-query cost regardless of memory size, even at 32,000 words No infrastructure to run—no vector database, cluster, or GPU needed Works with any model, so small local models gain the most from better retrieval
