Make printable kids' math worksheets and workbooks with answer keys on your own computer: addition and subtraction with or without regrouping, times tables, multi-digit multiplication, division with remainders or long-division layout, missing numbers, comparing numbers and clock faces. Every answer is computed and re-checked by code. Output Letter/A4 printables or a print-ready KDP workbook interior with cover size and checklist. No API key.
Make original mandala and geometric pattern coloring books from geometry code, not AI images, on your own computer: mandalas, Truchet curves, hexagon stars, fish scales, kaleidoscope tiles and triangle mosaics as clean vector line art. Simple, medium or detailed levels, a new seed for every page, single-sided layout. Output a KDP-ready interior with cover size and checklist, or Letter/A4 printables with 300 DPI PNGs. No API key, no image credits.
Generate word search, sudoku and maze books with answer keys on your own computer, as a print-ready KDP paperback interior or Letter/A4 printables. Every puzzle is checked by code: each word appears exactly once, every sudoku has exactly one solution, every maze has one path. Easy to hard, large print, how-to and solution pages, page numbers, KDP gutter and pre-flight, cover size and checklist. No API key.
Build print-ready Amazon KDP paperback interiors for journals, notebooks, planners and log books on your own computer: lined, dot, grid, prompt, year, monthly, weekly-spread, habit-tracker and log pages from a short book.json. KDP trim, page limits, bleed, the gutter for your final page count and 0.75 pt lines are applied, then a PDF pre-flight check runs. You also get the spine width, full cover size and a KDP checklist. No API key.
Build a hyperlinked PDF planner for tablet note apps on your own computer: cover, index, year at a glance, months with side tabs, weekly and daily pages, goals, habit trackers and notes, with every date, tab and breadcrumb linked. Any year or an academic start month, 5 themes, landscape or portrait, Monday or Sunday weeks. A link check confirms every tap lands on a page. No API key.
Turn a Word, Markdown or text manuscript into a Kindle-ready EPUB3 on your own computer. Chapters, linked contents, front and back matter and curly quotes are built for you; a pre-upload check finds what makes KDP conversion fail; and you get an eBook cover, the paperback cover size from KDP's spine formula with a 300 DPI wrap PDF, and a KDP listing sheet. No API key.
Word・テキスト・Markdownの原稿から、Kindle(KDP)にそのまま出せる縦書きEPUB3を手元で作ります。ルビ・縦中横・傍点・改ページ・目次・奥付を自動で組み、入稿前チェックで「変換に失敗する・ページが逆にめくれる・ルビが崩れる」原因を見つけ、文字だけの表紙とKDPの登録画面に写す表まで作成。Python標準ライブラリで動き、APIキー不要。
Turn a podcast, interview, stream or talk you made into short clips for TikTok, Reels and Shorts. Send its transcript (.srt, .vtt or timestamped text) and get the moments that stand alone with exact times, titles, hooks, on-screen text and captions, plus caption files and a script that cuts each clip to 9:16.
Name two NBA teams or ask for tonight's games and get a form-based preview from live public data: last ten results, point margin, home and road record, standings, recent meetings and rest (back-to-backs show up), a plain reading of which team holds the advantage, a short preview and a share card, in your time zone.

For a short you already posted. Send the video plus a screenshot of its retention graph (or your average % viewed) and get the curve redrawn with the drop-offs marked, the frame on screen at each drop, every leak ranked, a cut list with the new target length, and a verdict printed next to its threshold.
Send your short video and get its first six seconds read frame by frame: what is on screen and heard each second, where the picture freezes or the sound drops, a risk level per second with the reason, and three replacement openings to film. One report image plus the findings, for TikTok, Reels and YouTube Shorts.
Free. Name a league and get every fixture for the next seven days with each side's last five results and table position, in one table you can paste anywhere. 12 soccer leagues plus the NBA, WNBA, NFL, MLB and NHL. Facts only. No API key, no account.

Your script runs long and you are recording today. Open one HTML file in any browser - no install, no signup, no API key, no coding tool of any kind - and every line becomes a row you can keep, tighten or cut while the running total moves. It names the lines that would get you to your target, strips stock filler and reports what it cost, finds the block eating the overrun, checks a hook against the first seconds, and exports the recut script, caption cards and a printable shot list. Offline.
事業の情報を伝えるだけで、見積書と請求書を発行できる単一HTMLファイルをその場で作って渡します。屋号・住所・振込先・登録番号・通貨・税率・支払条件を焼き込んだ状態で出力。連番の自動採番、取引先と品目のプリセット、見積から請求へのワンクリック変換、税率ごとに区分した消費税額の表示、A4印刷でPDF化、JSON/CSVの書き出し。適格請求書の記載項目を入れる欄も用意します。買い切り版との違いは、税率が変わった時・項目を足したい時・年度が変わった時に何度でも作り直せることです。買い手の環境には何もインストールしません。税務・法務の助言ではありません。

Runs offline; your script is never uploaded.
重複判定のロジックと投稿履歴の保存先を貼るだけで、同じものを二度出す条件と、ガードが効きすぎて一度も出なくなる条件の両方を洗い出します。履歴の保持期間が切れて未投稿に戻る、ガードが毎回中止し続けてラインが恒久停止するデッドロック、失敗した投稿が履歴に残って永久にスキップされる、同時実行の競合など9項目を検査します。
1日あたりの投稿枠、補充の頻度と1回あたりの生産数、現在の在庫数を貼るだけで、週の収支とあと何日で枯れるか、週あたり何本足りないかを式の形で返します。休日だけの増枠が計算から漏れる、1回のバッチで作れる本数に上限がある、補充は成功しているのに量が足りない、作成済みと未使用を分けて数えていないなど9項目を検査し、安全在庫の決め方まで返します。
投稿の公開範囲設定と直近の再生数・表示回数の一覧を貼るだけで、「誰にも届いていない」原因を切り分けます。確認中の扱いで下書きに残る、公開範囲が非公開や限定公開のまま、同一タイトルの重複アップロード、興味分類と投稿ジャンルの不一致、タグの文字化けで検索の入口が消えるなど9項目を検査し、そのまま使える確認手順と次に投稿する時の作り方を返します。
ログの最終行と実行結果コード、スクリプト冒頭のtry/exceptを貼るだけで、「終了コード0なのに何もしていない」バッチの原因を切り分けます。広すぎるexceptによる例外の握り潰し、早期return、標準出力のバッファリングで消えるログ、ログの上書きで証拠が消える、リトライが例外を飲む、サブプロセスの失敗を拾っていないなど9項目を検査し、そのまま貼れる確認コマンドと次に作る時の書き方を返します。
Windowsタスクスケジューラの設定を貼るだけで、「登録されているのに動かない」「エラーも出ずに無言で止まる」原因を特定します。バッテリー駆動中の無言スキップ、日本語パスの文字化け、トリガーとアクションの1対1誤解、同時刻タスクの巻き添えなど9項目を検査し、そのまま貼れる確認コマンドと修正コマンドを返します。
化粧品・医薬部外品・健康食品・サプリの広告文を貼るだけで、薬機法第66条の虚偽誇大広告と医薬品的効能効果の標ぼうの観点から危ない表現を原文引用つきで指摘し、NG→OKの言い換え表と、訴求力を落とさずに書き直した安全版を返します。第66条の対象は「何人も」で、広告主だけでなく書き手本人も含まれます。
商品紹介やPR投稿の下書きを貼るだけで、ステマ規制と優良誤認・有利誤認の観点から危ない箇所を1行ずつ引用付きで指摘し、訴求力を落とさずに書き直した安全版を返します。媒体別のPR表記位置まで判定します。
Send a topic, get one complete faceless short-form video plan back in a single reply: three hooks with their visuals, a second-by-second shot list timed by speech rather than character count, TTS-ready narration, stock-footage search terms per shot, captions and tags for TikTok, Reels and YouTube Shorts, a cover-frame spec, and a retention review that names the seconds where viewers leave. Thirty requests is a month of daily uploads.
Paste a caption and get every hashtag checked for the silent corruption that kills tag-driven distribution. Check before posting, or compare what you intended against what the platform actually saved and see which tags died.
For one person publishing their own content on a schedule: describe your setup and get an operations kit that makes silent failures visible — a status board, a runbook with idempotent retry and queue-fallback patterns, an incident ledger, and a daily health-check specification.
