Tagline	AI-powered networked notes. Roam with a brain.	Meta FAIR's open-source Python library that finally bridges the gap between neuroimaging data (fMRI, EEG, spikes) and modern deep learning pipelines.	Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.	Run any open-source AI model with an API call.
Category	Productivity	Research	Coding	Dev Platform
Pricing	$10/mo	Free (MIT open source)	Free (limited) + $10/mo Pro + $19/mo Business	Pay per second of compute
Best for	Knowledge workers + thinkers who want AI in their second brain.	Computational neuroscience researchers who want to train deep learning models on brain recordings without building custom data pipelines from scratch.	Teams with GitHub already. Devs who don't want to change IDEs.	Developers using open-source models (Flux, SDXL, Whisper, etc).
Strengths	AI auto-links related notes Generates backlinks + summaries Clean, minimal 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	Great enterprise story Works in your existing IDE Chat + autocomplete	Tens of thousands of models (image, video, audio, LLMs) One-line API for any model Cog framework for custom model deploy
Weaknesses	Expensive for just notes Smaller community than Obsidian	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	Less agentic than Cursor/Claude Code Model quality varies	Cold starts on less-popular models Pricing gets real at scale
Kai's verdict	A-tier. Niche but beloved. If you've outgrown Notion, try this.	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.)	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for open-source model APIs. The default in this space.
