TaglineAI-powered networked notes. Roam with a brain.Qwen's open-source GPU kernel library that squeezes 2–3× more speed out of linear attention on NVIDIA Hopper hardware — if you're lucky enough to own one.Commercially safe image gen, deeply integrated with Photoshop.Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration.

Best forKnowledge workers + thinkers who want AI in their second brain.ML engineers and researchers running Qwen3.x linear-attention models on H100/H200 clusters who need to close the gap between theoretical GDN efficiency and actual hardware throughput.Anyone in Creative Cloud. Brands that need copyright clarity.Teams with GitHub already. Devs who don't want to change IDEs.
Strengths
  • AI auto-links related notes
  • Generates backlinks + summaries
  • Clean, minimal UX
  • 2–3× forward-pass and ~2× backward-pass speedup over FLA Triton kernels on Hopper GPUs
  • Gate-driven automatic intra-card context parallelism boosts SM utilization in long-sequence, small-head-count regimes without manual config
  • Hardware-friendly algebraic reformulation reduces Tensor Core, CUDA Core, and SFU overhead with no numerical precision loss
  • MIT licensed and fully open-source — drop it straight into Qwen3.x training and inference pipelines
  • Trained on licensed content — commercially safe
  • Generative Fill in Photoshop is incredible
  • Native to Adobe ecosystem
  • Great enterprise story
  • Works in your existing IDE
  • Chat + autocomplete
Weaknesses
  • Expensive for just notes
  • Smaller community than Obsidian
  • Extremely narrow hardware requirement: SM90+ only (H100/H200, DGX Spark) with CUDA 12.8+ and PyTorch 2.8+ — useless outside Hopper-class clusters
  • GDN/Qwen-specific: not a drop-in replacement for FlashAttention-style softmax kernels, and won't help you if you're not running linear-attention Qwen models
  • Very new, minimal community adoption or third-party validation yet
  • Aesthetic ceiling below Midjourney
  • Tied to Adobe subscription
  • Less agentic than Cursor/Claude Code
  • Model quality varies
Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A genuinely impressive, laser-focused kernel optimization from the Qwen team — real speedups on real hardware — but its utility is gated behind Hopper GPUs and Qwen's GDN architecture, making it a niche power tool rather than a broadly useful library. (Verdict pending Phi's full review.)S-tier inside Photoshop (Generative Fill). B-tier standalone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
