Creative Writing — Novel First Draft

Live Markdown editor with real-time HTML preview. Supports headings, bold, italic, links, code blocks, tables, and blockquotes.

Measure manuscript progress from your own starting count and observed days, or divide remaining words exactly among your available writing sessions.

Plan chapter counts near your chosen word target or a maximum length, and inspect an exact whole-word distribution that preserves the manuscript total.

Estimate text pages from your own word density, add separately counted pages, and compare one-sided or two-sided printing for a paper-sheet plan.

Count words, Unicode characters, sentences and paragraphs. Inspect English readability, estimate reading time and compare a selected publishing length rule.

Compare dialogue and narrative percentages from two manually counted word categories, with the total shown and no automatic writing-quality judgment.

Estimate reading or narration time from your own effective words-per-minute rate, with optional page estimates using your chosen word density.

Calculate one royalty basis, rate and deduction schedule at a time. Enter terms from your agreement or publisher quote; this does not select platform rates.

Estimate spoken duration from your narration pace and recording time from an explicit productive-time ratio measured in a trial session.

Estimate a manuscript editing pass from your own rate or a timed sample, with remaining work, session counts and a final session allowance.

Plan remaining drafting work from your editorial word target, current count and measured writing pace, with no invented SEO length requirement.

Check complete posts with destination-specific Unicode counting, retain draft settings, and download the current report or a restorable JSON backup.

Calculate reported open, click and click-to-open rates from unique recipients in one send, with delivered counts and tracking limitations visible.

Estimate 3D printing filament usage in grams and meters from model volume and infill. Plan material costs and spool requirements for FDM print jobs.

Calculate 3D print weight from dimensions, infill percentage, and material density. Estimate part mass for FDM functional and structural prints.

Calculate 3D print speed settings from volumetric flow rate and layer dimensions. Set max speed within extruder and hotend flow limits.

Calculate optimal layer height from nozzle diameter and print quality target. Set layer resolution as a fraction of nozzle size for best FDM results.

Build a transparent 3D print cost scenario from material, power, machine time, labor, consumables, contingency, and pricing method.

Calculate diagonal angle-of-view focal-length equivalence from actual focal length and exact source/reference image-area width and height.

Calculate thin-lens near/far focus limits and hyperfocal distance from actual focal length, focus distance, f-number, and an entered CoC criterion.

Calculate EV100 and ISO-normalized setting indexes plus an equal-exposure shutter time from aperture, seconds, ISO, and comparison aperture.

Translate a documented or tested flash guide number to a target ISO, then solve a nominal direct-flash f-number or same-unit distance.

Calculate thin-lens hyperfocal distance and its exact entered-criterion near limit from actual focal length, taking f-number, and explicit circle of confusion.

Calculate the largest whole-pixel golden-ratio candidate rectangle inside a source image, including exact edge exclusions and retained pixels.

Calculate print size at entered image PPI, then audit retained pixels, fill crop, effective PPI, and pixel differences for one exact target.

Reproduce decimal video-file size from documented video/audio bitrates, duration and explicit container overhead, then compare an independent file-size record.

Reproduce and compare active square-pixel sample counts, decimal megapixels and axis ratios for two explicit reviewed raster records.

Reproduce media-set capacity from a reviewed inventory, per-item payload, explicit working overhead and reserve, then compare an independent capacity record.

Reproduce reviewed square-pixel active-image geometry for a documented target canvas using an explicit Fit/Pad or Fill/Crop mode and rounding rule.

Reproduce a strictly sequential render or export queue from two named completed work-and-elapsed-time observations, explicit fixed overhead, and an independent duration record.

Calculate exact lumber board feet, a user-chosen planning allowance, and a price scenario from measured dimensions and whole-piece count.

Reconcile one uniform rectangular lumber group from actual dimensions, an exact piece count, and a documented density interval matched to the recorded material condition.

Estimate and document one signed radial or tangential dimension change for unrestrained solid wood using a USDA FPL table coefficient or a source-owned coefficient.

Reconcile a symmetric through-dovetail tail-board layout with explicit half-pins, slope projection, uncertainty bounds, and baseline-to-end station coordinates.

Compare 12 transparent orthogonal candidates for up to three rectangular groups on one exact usable plywood stock record.

Generate scan-testable URL, email, phone, WiFi, or escaped vCard QR codes with UTF-8 capacity checks, color warnings, raster logos, PNG, and SVG.

Calculate whole-pixel image dimensions with a locked ratio or independent width and height, then compare scale and pixel area before exporting in an editor.

Preview sRGB colors with adjustable color-vision models. Compare palettes and text pairs, check original contrast, and copy the simulated colors as CSV.

Generate harmonious color palettes from a base color. Complementary, analogous, triadic, tetradic, monochromatic. CSS variables, Tailwind config, WCAG contrast.

Calculate total ROI and net gain or loss, then use CAGR for endpoint-only investments or money-weighted IRR for explicit year-end contributions.

Professional color picker with HEX, RGB, and HSL conversion, WCAG contrast checking, and palette generation. Pick colors and copy CSS-ready values instantly.

Compare a measured sample or true peak with a chosen ceiling, or calculate peak-to-RMS crest factor using compatible digital levels.

Calculate byte-aligned PCM payload and explicit overhead from sample rate, stored sample width, channels and duration. Compare bytes, MB and MiB.
