Compare AI tools

	Sudowrite S	NeuralSet A	GitHub Copilot B	Leonardo.ai A
Tagline	AI writing tool built specifically for fiction writers.	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.	Gamer + creator image gen with model fine-tuning built in.
Category	Writing	Research	Coding	Image
Pricing	$19-$59/mo	Free (MIT open source)	Free (limited) + $10/mo Pro + $19/mo Business	Free + $12-$60/mo
Best for	Novelists, screenwriters, fiction short-form writers.	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.	Indie game devs, illustrators, anyone training custom style models.
Strengths	Brainstorm, expand, rewrite modes designed for fiction Story Bible for character + plot tracking Understands voice + tone better than generic chatbots	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	Train your own models on your style/character Great for game art + concept art Generous free tier
Weaknesses	Pricey for casual use Fiction-only focus — not for business writing	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	General output behind Midjourney Can be overwhelming
Kai's verdict	S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.	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.	A-tier for creators training custom looks. B-tier for general use.
