Generate and parse llms.txt and llms-full.txt (the llmstxt.org standard) — a Markdown map of your site for LLMs. Zero-dependency, isomorphic.

Keyless, local-first RAG in one CLI — index a folder of docs, then query and ask grounded questions. Ollama by default (100% free, no API key), OpenAI-compatible too. Zero dependencies.

A content-hash cache for LLM calls — key by (model family, prompt version, normalized input) so identical requests, retries after a 429, and repeated rewrites never pay twice. Pluggable async store (in-memory LRU built in, Mongo/Redis/KV via a tiny adapte

A tiny, zero-dependency, provider-agnostic LLM chat client over fetch — one chat()/stream() API for OpenAI, Anthropic, Google Gemini and any OpenAI-compatible endpoint (Groq, Together, OpenRouter, Ollama), plus typed message builders, retry/backoff + time

A tiny, typed prompt-engineering toolkit — build, compose and render LLM prompts and chat messages with real type safety. Variable names are inferred from the template string, so .render() is type-checked. Zero-dependency, isomorphic, provider-agnostic.

A tiny, zero-dependency in-memory vector store for RAG and semantic search — upsert records, brute-force k-nearest-neighbour query with cosine / dot / euclidean metrics, metadata filtering, and plain-JSON persistence. Isomorphic and fully typed.

Engine-agnostic text-to-speech pipeline for Nepali and English newsrooms — @lacspace/speakable normalisation (numbers, BS dates, currency, acronyms, names) → edge-tts CLI (Microsoft neural voices, word-level timings from its subtitles), Piper offline voic

Engine-agnostic spoken-form normaliser for Nepali and English text-to-speech. Rewrites what TTS engines mangle before any engine sees it: numbers (unique Nepali 0–99 words, लाख/करोड scales, डेढ/अढाई/साढे idioms, decimals), Bikram Sambat and AD dates (२०८३

The zero-dependency glue for a Retrieval-Augmented Generation pipeline — index documents and retrieve + assemble prompt context by composing an injected embedder, vector store and splitter. Keyless, isomorphic and fully typed.

A fast, zero-dependency token estimator, LLM cost calculator and context-budget manager — good-enough approximation of GPT/Claude/Gemini token counts without the 3 MB tiktoken/wasm. Context-window usage, batch estimation and cross-model cost comparison. I

AI key pooling two ways. createAiChain: route-ordered multi-provider failover (Gemini, Groq, Cerebras, OpenAI, Anthropic, DeepSeek, OpenRouter, any OpenAI-compatible) that rests key+model pairs on 429 (Gemini daily quota until Pacific midnight), quarantin

Mix a newsroom voiceover with a music bed: sidechain-duck the music under the voice, place SFX stings, and normalize to -14 LUFS — an ffmpeg command builder plus a licensed-music library loader (local tracks with a licence sidecar) AND a free Creative-Com

Build and parse robots.txt — typed per-user-agent rules, AI-crawler block presets (GPTBot, ClaudeBot, CCBot, Google-Extended), sitemap refs and Next.js robots.ts output. Zero-dependency, isomorphic.
