Precise little tools for AI-era text work.
Estimate tokens, build reusable prompts, clean messy text and extract JSON — four focused utilities that do one job each, then get out of your way.
Token & cost estimator
Paste any text to estimate its token count and the cost of one call across popular models.
- Tokens (est.)
- 0
- Characters
- 0
- Input cost
- $0
- Output cost
- $0
Heuristic estimate: CJK ≈ 1 token per character, other scripts ≈ 1 token per 4 characters. Pricing is indicative — check the provider's official pricing page.
Why Toolstack
Small surface, deliberate depth.
Content pipeline, built in
Every page ships pre-rendered HTML with one canonical graph of structured data, heading hierarchy that never skips, and FAQ markup out of the box. Writers touch Markdown; the system handles the rest.
Local-first by default
Regex, parsing and counting run on your machine. No upload, no queue, no retention policy to trust. And the same components render both marketing pages and tool islands, so the whole site stays on one visual system.
Fast everywhere
Static-first delivery, zero JS on content pages, hydration only where a tool needs it.
One design system
Tokens, not opinions: a single radius, two elevation levels, one accent hue. Dark and light are the same system, re-weighted.
The toolkit
Four tools. Zero fluff.
Token Estimator
Characters, tokens and API cost as you type. Batch mode for prompt libraries.
Runs locallyPrompt Builder
Compose prompts from reusable blocks with [[variables]] and one-click export.

Strip smart quotes, zero-width characters and double spaces; normalize dashes.
Runs locallyJSON Extractor
Pull valid JSON out of noisy LLM output, with schema checks and pretty-print.

FAQ
Questions people actually ask.
Are the tools free to use?
Yes. Every tool runs entirely in your browser and is free without an account. Accounts only add credits for the optional API features.
Do you store the text I paste?
No. All processing is local-first — nothing is uploaded, logged or retained. Close the tab and it's gone.
How is token usage estimated?
Estimates use a characters-per-token heuristic tuned for English and code, accurate within roughly 10% for most mainstream models. Exact tokenizers vary slightly between providers.
Can I reuse this site as a template?
That's the point. Pages are Markdown-driven, components are pre-built blocks, and SEO structure (titles, schema graph, sitemap, breadcrumbs) is generated at build time.
