7 free tools Nothing uploaded

Free assignment toolkit that stays on your device

Convert Word and Excel files, clean pasted text, check a word count, split a long prompt for an AI tool, compare two drafts and format references. No account, no upload and no server-side processing.

What this is

A browser-only toolkit for the work around an assignment: turning briefs and spreadsheets into portable text, checking the draft against the brief, and preparing citations. Every tool runs locally, so it works on a static host such as Vercel, Netlify or AWS Amplify without a database or Python runtime.

Excel to MarkdownTurn a spreadsheet into a Markdown table without retyping a single cell. Choose a sheet, copy the pipe table and paste it into an AI prompt, README, Notion page or assignment appendix.Open tool Word to MarkdownPaste a Word document into an AI tool, README or note-taking app without fighting the formatting. Convert .docx to Markdown locally, then copy or download the result.Open tool Text CleanerPaste the messy version. Strip smart quotes, double spaces, stray bullets, duplicate lines and tracking links before you paste the text into Word, Excel or an AI prompt.Open tool Word CounterPaste the draft and see whether it fits the brief. Get word and page counts, the ±10% target band, readability, reading time and the long sentences or filler phrases a marker is likely to flag.Open tool Token ChunkerLong draft, small context window? Estimate the token count, choose a chunk size and split the text at paragraph and sentence boundaries — with optional overlap so the model does not lose the thread.Open tool Text Diff CheckerPaste the original and the revision. See exactly which lines were added, removed or left alone before you accept an AI rewrite or submit the second draft.Open tool Reference FormatterBuild a clean reference list without guessing where the commas go. Choose a source type and style, check the preview, then add each entry to a bibliography you can export.Open tool

Private by design

Files and text are processed in JavaScript on your device. Nothing is uploaded, logged or stored in an account.

No backend required

No Python, OCR model, SQLite database or API key. That is why the toolkit can run on a static or serverless host such as Amplify.

Built for the whole task

Convert the brief, check the draft, split the prompt and format the references — not just one isolated step.

What is not in this toolkit

PDF → Markdown, image OCR, PowerPoint conversion and the SQLite-based assignment tracker need server binaries, Python packages or a persistent database. They are deliberately excluded because they cannot run reliably in a browser-only page or on a static Amplify deployment. If you need one of those workflows, use a desktop tool or a server-backed converter instead of a tool that claims to be private but uploads your file.

Questions

Are these assignment tools really free?

Yes. Every tool is free with no signup, no trial and no usage limit. There is no paywall on the results, and the downloaded files are yours to keep.

Is my document or draft uploaded?

No. The Word, Excel, text, chunking and diff tools run entirely in your browser using JavaScript. Files and pasted text never reach our server, and nothing is logged or stored in an account.

Why are PDF, image OCR and PowerPoint conversion not included?

Those converters need Python libraries, OCR models or server-side parsing. They cannot run reliably as browser-only tools or on a static Amplify deployment, so they are intentionally excluded. The tools here work without a backend.

Can I use these tools for university assignments?

Yes, for preparation and quality control: convert a brief, check a word count, clean a draft, split a prompt and format references. Always follow your institution's rules on AI assistance and cite sources correctly.

Do the tools work on mobile?

Yes. They are responsive web pages and work in modern mobile browsers. Very large files are best handled on a desktop because parsing happens on your device.

When the deadline is closer than the learning curve

The toolkit prepares the work. We can finish the workbook.

Send the Excel file, brief and rubric. A human Excel expert returns a tested workbook with the formulas explained — usually within 24 hours, from $15/hr with a fixed quote.
