# Tutu Office (TutuDocs) > Tutu Office (tutudocs.com) provides online document, spreadsheet and presentation editors, 31 built-in templates, and 13 PDF↔Office conversions. Everything is free, needs no account, has no usage limit, and exports carry no watermark. While signed out, files are processed in the browser only and are never uploaded. ## Editors - [Online spreadsheet](https://tutudocs.com/excel): 500+ formula functions, charts, pivot tables, conditional formatting, filter and sort. XLSX / CSV / TSV / HTML compatible, exports to PDF. - [Online document](https://tutudocs.com/doc): rich text, heading outline, table of contents, comments, headers and footers, footnotes, watermark. DOCX compatible, exports to DOCX / PDF / Markdown / HTML / TXT. - [Online slides](https://tutudocs.com/ppt): themes, shapes, animations, transitions, presenter view, slideshow. PPTX compatible, exports to PPTX / PDF / PNG. ## AI assistant - [AI assistant](https://tutudocs.com/en/ai): edits the document, spreadsheet or slides you have open — writes formulas, inserts charts, rewrites text, builds tables, checks layout with a screenshot — instead of replying with text to copy; every round can be undone in one click. Works without an account with a free daily allowance (metered by tutuagent). When you use the AI, whatever you ask it to read is sent to the model. It cannot read tables or text inside images; to generate a whole multi-slide deck from a topic, use tutuagent. ## Templates (31, one click opens the editor with content in place) - [All templates](https://tutudocs.com/en/templates) · [Documents](https://tutudocs.com/en/templates/doc) · [Spreadsheets](https://tutudocs.com/en/templates/excel) · [Slides](https://tutudocs.com/en/templates/ppt) - Templates with their own page: [resume template](https://tutudocs.com/en/templates/resume) · [cover letter template](https://tutudocs.com/en/templates/cover-letter) · [meeting notes template](https://tutudocs.com/en/templates/meeting-notes) · [project plan template](https://tutudocs.com/en/templates/project-plan) · [checklist template](https://tutudocs.com/en/templates/checklist) · [monthly budget template](https://tutudocs.com/en/templates/budget) · [invoice template](https://tutudocs.com/en/templates/invoice) · [task tracker template](https://tutudocs.com/en/templates/task-tracker) · [weekly schedule template](https://tutudocs.com/en/templates/schedule) · [expense report template](https://tutudocs.com/en/templates/expense-report) · [pitch deck template](https://tutudocs.com/en/templates/pitch-deck) · [status report deck](https://tutudocs.com/en/templates/status-report) · [attendance sheet template](https://tutudocs.com/en/templates/attendance-sheet) · [inventory template](https://tutudocs.com/en/templates/inventory) · [gradebook template](https://tutudocs.com/en/templates/gradebook) · [monthly calendar template](https://tutudocs.com/en/templates/calendar) · [savings tracker template](https://tutudocs.com/en/templates/savings-plan) · [lesson slides template](https://tutudocs.com/en/templates/lesson-slides) · [training deck template](https://tutudocs.com/en/templates/training-slides) · [quarterly review deck](https://tutudocs.com/en/templates/quarterly-review) · [project proposal deck](https://tutudocs.com/en/templates/proposal-deck) · [portfolio deck template](https://tutudocs.com/en/templates/portfolio-deck) · [press release template](https://tutudocs.com/en/templates/press-release) · [formal letter template](https://tutudocs.com/en/templates/business-letter) ## Tools (some give the result on the page, others carry the file into the editor and do the job) - [All tools](https://tutudocs.com/en/tools) - [Word counter](https://tutudocs.com/en/tools/word-count): Paste text or drop a Word file for an instant count - [Chart maker](https://tutudocs.com/en/tools/chart-maker): Paste table data, get a bar or pie chart - [CSV editor](https://tutudocs.com/en/tools/csv-editor): Drop a CSV and edit it like Excel - [Pivot table](https://tutudocs.com/en/tools/pivot-table): Drop a sheet and the pivot dialog opens - [Present a PPT](https://tutudocs.com/en/tools/slideshow): Drop a PPTX and start the show - [Table of contents](https://tutudocs.com/en/tools/table-of-contents): Drop a Word file and get a TOC from its headings ## Conversions (all in-browser, nothing uploaded) - [PDF to Word](https://tutudocs.com/en/convert/pdf-to-word) · [PDF to Excel](https://tutudocs.com/en/convert/pdf-to-excel) · [PDF to PPT](https://tutudocs.com/en/convert/pdf-to-ppt) · [Word to PDF](https://tutudocs.com/en/convert/word-to-pdf) · [Excel to PDF](https://tutudocs.com/en/convert/excel-to-pdf) · [PPT to PDF](https://tutudocs.com/en/convert/ppt-to-pdf) · [Word to Markdown](https://tutudocs.com/en/convert/word-to-markdown) · [PPT to images](https://tutudocs.com/en/convert/ppt-to-image) · [Markdown to Word](https://tutudocs.com/en/convert/markdown-to-word) · [HTML to Word](https://tutudocs.com/en/convert/html-to-word) · [TXT to Word](https://tutudocs.com/en/convert/txt-to-word) · [Word to TXT](https://tutudocs.com/en/convert/word-to-txt) · [XLS to XLSX](https://tutudocs.com/en/convert/xls-to-xlsx) ## Information - [What is free](https://tutudocs.com/en/free) · [Are my files safe](https://tutudocs.com/en/security) · [Help](https://tutudocs.com/en/help) · [About](https://tutudocs.com/en/about) · [Contact](https://tutudocs.com/en/contact) - [Embed the editor in your site](https://tutudocs.com/en/embed): one script tag, self-service key, no review. - [Privacy](https://tutudocs.com/en/privacy) · [Terms](https://tutudocs.com/en/terms) ## Limits (stated so you do not have to guess) - No real-time multi-user collaboration. - Scans (pages that are just images) need in-browser text recognition first, with a one-off ~6 MB engine download; handwriting and badly skewed or blurred pages still come out wrong. - Office to PDF produces a layout-faithful raster; the text is not selectable or searchable (no embeddable CJK font is available in the browser). - Complex documents may lose some formatting on a round trip to and from Office. - PDF merge, split and compress are not here — those act on the file container and belong to TutuDrive (tutudrive.com).
