Garden plan

Tomatoes along the south fence this year, basil between them. The beds by the shed get too much shade after June, so herbs go there.

Read and write in a real editor. Pages that print the way they look, PDFs you can edit, notes, drawings and spreadsheets, all in one app, with or without an ai.

Big Excel workbooks, all of them at once.

Excel workbook · 1,000,000 rows
Every sheet, formula and chart. Open .xlsx workbooks of a million rows and zoom out until you see all of it. Formulas calculate as Excel calculates them, charts, pivot tables, conditional formatting and sparklines show as they do there, and it saves back as .xlsx that Excel opens as it was. Every format ›

Your second brain, in plain files.

Tomatoes

San Marzano again this year, along the south fence. Where they go is in Garden plan.

Linked from Diary and Recipes

Links follow a rename

Write notes in Markdown, link them with [[wikilinks]], and keep your Word files, PDFs and drawings right beside them, in folders you choose. Rename a note and every link to it follows.

It’s all ordinary files in a folder on your computer, so an Obsidian vault opens as it is, and nothing is locked inside Golem Docs.
