Developer & SEO toolsAI Token Calculator
The AI Token Calculator estimates token consumption, character-to-token ratios, and API inference costs across leading foundation models (OpenAI GPT-4o, Claude 3.5 Sonnet, Gemini 1.5/2.0, and Llama 3) without requiring an API key.
Developer & SEO toolsTokens to Words Calculator
The Tokens to Words Calculator translates AI token quantities into human-readable word counts, estimated character lengths, reading durations, and standard book or document pages.
Developer & SEO toolsWords to Tokens Calculator
The Words to Tokens Calculator computes the estimated number of subword tokens from word counts or raw text inputs, highlighting context window utilization across major LLM architectures.
Developer & SEO toolsRAG Chunk Size Calculator
The RAG Chunk Size Calculator helps AI engineers and software architects calculate total chunk count, overlap percentage, vector storage requirements, and optimal chunk sizes for Retrieval-Augmented Generation architectures.
Developer & SEO toolsEmbedding Cost Calculator
The Embedding Cost Calculator models one-time indexing expenses, recurring incremental re-indexing costs, and vector database storage requirements across top embedding models.
Developer & SEO toolsSitemap URL Counter
The Sitemap URL Counter parses XML sitemaps and sitemap indexes, providing instant counts of indexable URLs, child sitemaps, protocol hygiene (HTTPS vs HTTP), metadata tag coverage, and Google compliance limits.
Developer & SEO toolsOG Image Size Checker
The OG Image Size Checker validates social share preview images against official Facebook (1200x630), Twitter/X Large Summary Card (1200x628), and LinkedIn dimension standards, preventing blurry previews or awkward center-crops.
Developer & SEO toolsCanonical Tag Checker
The Canonical Tag Checker inspects HTML head tags and URLs to detect duplicate canonical declarations, protocol mismatches, relative link errors, trailing slash conflicts, and cross-domain canonical signals.
Developer & SEO toolsRobots.txt Tester
The Robots.txt Tester evaluates website crawling permissions according to the RFC 9309 Robots Exclusion Protocol, verifying whether specific user-agents (Googlebot, Bingbot, GPTBot, ClaudeBot) are permitted or blocked from crawling designated URLs.
Developer & SEO toolsBug Report Generator
The Bug Report Generator structures software defect logs into standardized, actionable engineering tickets. Export formatted markdown for GitHub, Jira syntax, or plain text for Slack and email.
Developer & SEO toolsPrompt Token Counter
The Prompt Token Counter separates LLM prompts into modular architectural components—System Instructions, User Prompts, Few-Shot Examples, and RAG Retrieval Context—calculating token weights, prompt bloat ratios, and model context ceilings.
Developer & SEO toolsOpenAI Token Counter
The OpenAI Token Counter models Byte-Pair Encoding (BPE) across OpenAI's official tokenizers (o200k_base for GPT-4o/mini, cl100k_base for GPT-4/Turbo, and p50k_base for legacy models), providing granular token-to-word ratios and price calculations.
Developer & SEO toolsRAG Chunk Overlap Calculator
The RAG Chunk Overlap Calculator computes the mathematically optimal token overlap for text splitting in vector pipelines, preventing context fragmentation while eliminating duplicate token storage bloat.
Developer & SEO toolsVector Database Storage Calculator
The Vector Database Storage Calculator models raw vector memory, HNSW graph index overhead, metadata payload storage, and quantization savings (Float32 vs Float16 vs Int8) for production vector databases.
