	Perplexity S	Rows A	NeuralSet A
Tagline	AI search done right. Cited answers, not chat theater.	Spreadsheets with AI + live integrations baked in.	Meta FAIR's open-source Python library that finally bridges the gap between neuroimaging data (fMRI, EEG, spikes) and modern deep learning pipelines.
Category	Research	Data	Research
Pricing	Free + $20/mo Pro	Free + $19-$89/user/mo	Free (MIT open source)
Best for	Replacing Google for any question where you want a cited answer in seconds.	Ops teams, marketers, anyone building dashboards from multiple sources.	Computational neuroscience researchers who want to train deep learning models on brain recordings without building custom data pipelines from scratch.
Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Pull live data from Stripe, Slack, Google Analytics, etc. AI functions inside cells Modern UX	Unified interface across fMRI, MEG, EEG, iEEG, fNIRS, EMG, and spike trains — no more siloed modality-specific tools Lazy, memory-efficient loading that scales to terabyte-scale OpenNeuro datasets without RAM blowout Native HuggingFace integration for embedding stimuli (text, audio, video) using models like DINOv2, CLIP, Wav2Vec, and more Pydantic-based config validation catches bad BIDS paths or filter settings at init, not after hours of wasted compute Scales from local laptop prototyping to SLURM clusters without rewriting infrastructure code
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Not a full Excel replacement for heavy users Integrations best on paid tiers	Extremely niche audience — only useful to neuro-AI researchers with Python/PyTorch chops and access to neuroimaging datasets No GUI or managed cloud environment; requires local setup and familiarity with BIDS data formats Still a preprint-stage release with no arXiv paper yet — API stability and long-term maintenance are unproven
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier. The most interesting spreadsheet in years. Great for ops dashboards.	If you're doing neuro-AI research, this is the plumbing you've been manually building for years — finally done right by the team that actually runs these experiments at scale. Extremely narrow use case, but within that lane it looks genuinely best-in-class. (Verdict pending Phi's full review.)
