Claude Code Local turns your MacBook into a fully self-contained Claude Code environment, replacing the Anthropic API backend with locally-running models on Apple Silicon. Choose from Qwen 3.5 122B (65 tok/s), Llama 3.3 70B (7 tok/s), or Gemma 4 31B (15 tok/s) — all running via the MLX framework on your GPU, no internet required. Four operating modes are included: standard IDE coding, browser automation agent, hands-free voice with voice cloning, and an iMessage pipeline integration. The privacy commitment is absolute — zero outbound network calls from the project's own code. The only exception is a one-time startup handshake to verify Claude Code's binary. Purpose-built for NDA environments, legal workflows, and healthcare use cases where sending code to a cloud API is a non-starter. With 2,300+ stars and 453 forks, Claude Code Local is quietly becoming the go-to for privacy-conscious developers. Version 2 fixed critical tool-call formatting bugs that caused infinite loops in local models, and a 98/98 test suite pass rate suggests production readiness.

Most AI text detectors are cloud services with opaque models, significant false positive rates, and zero explanation for why they flagged content. lmscan is a zero-dependency Python package that runs entirely offline using 12 statistical linguistic features: perplexity scoring, burstiness analysis, vocabulary density, syntactic variety, and others. It's not just detection — it fingerprints the specific LLM family responsible, distinguishing between GPT-4, Claude, Gemini, Llama, and Mistral outputs based on their characteristic writing signatures. Every result is fully explainable, showing which features drove the classification. The design philosophy is explicitly anti-black-box: every classification comes with a feature-by-feature breakdown, making it suitable for applications where you need to explain the result to a human (academic integrity, content moderation, employment screening). The CLI interface drops into CI/CD pipelines for automated content checking, and the Python API integrates into document processing workflows. No API key, no network call, no vendor lock-in. Very early project — minimal stars and community traction as of this writing. The statistical approach trades accuracy for explainability, which means sufficiently paraphrased AI text will evade detection just as it does on competing services. But for a free, fully offline, explainable baseline for AI text analysis, it occupies a niche that no established tool does cleanly. Worth monitoring for teams that need local, auditable AI detection without vendor dependency.

Reviewer scorecard

65 tok/s Qwen locally is actually usable for real coding — the v2 fixes to tool-call formatting make a huge difference. For NDA client work where I can't send code to Anthropic, this has become essential. The MLX optimization is genuinely impressive engineering.

80/100 · ship

The zero-dependency, fully offline angle makes this immediately viable for enterprise environments where you can't send content to a third-party API for compliance reasons. The LLM fingerprinting feature is genuinely novel — I haven't seen another tool that tries to attribute text to specific model families. Early days, but the CI/CD integration and explainable output make it worth piloting for document pipelines where you need auditable AI detection.

Skeptic
45/100 · skip

Local models still lag behind Claude 3.5 Sonnet significantly on complex coding tasks. You're trading quality for privacy and cost savings — a reasonable trade for some, but a painful one for gnarly refactoring jobs. The gap is real and matters.

45/100 · skip

Statistical AI text detection is a fundamentally broken approach — anyone who rewrites AI output a couple of times will evade it, and false positive rates on certain human writing styles (non-native English speakers, highly technical prose) can be significant. The LLM fingerprinting claim sounds exciting but needs rigorous benchmark testing before I'd trust it in a real content moderation or academic integrity context. Ship it when there's an accuracy paper.

Futurist
80/100 · ship

When you can run a 122B model at 65 tok/s on a laptop, the question of 'cloud vs local' becomes a policy choice, not a capability choice. This project shows that frontier AI is commoditizing faster than most vendors want to admit.

80/100 · ship

As AI-generated content saturates every channel, the tools for detecting and attributing it become infrastructure, not just features. lmscan's offline, explainable approach points toward the right architecture: detection capability should be embeddable and auditable, not locked behind API calls. The specific LLM attribution angle — figuring out which model family produced text — will become increasingly important for provenance tracking and regulatory compliance.

Creator
80/100 · ship

The hands-free voice mode with voice cloning is the sleeper feature — coding by talking to your Mac is surreal and surprisingly productive. For accessibility-focused builders and creative technologists, this opens doors that cloud API pricing keeps shut.

45/100 · skip

If you're a creator who worries about AI-generated content flooding your niche or competitors using AI to impersonate your style, this is theoretically relevant. But the accuracy question is real — statistical detection won't catch polished AI content, and false positives could flag your own work. Interesting concept that needs a lot more development before it's trustworthy for real editorial decisions.
