Describe a table. Get a working spreadsheet.

Tell JustJot.ai what you need — "a tracker with columns for launch date, owner, status, and budget" — and it builds the sheet for you with typed columns and default values.

Add computed columns in plain English: "profit margin as revenue minus cost divided by revenue." The engine translates that into a deterministic calculation run over every row.

Ask "which projects are over budget and not yet shipped?" and get a filtered, sorted view with an automatic chart — no pivot tables or filter dropdowns required.

Point the sheet builder at a research report, a Space, or a set of notes. It pulls the relevant rows out of unstructured text and populates the table for you.

Filter, group, aggregate, pivot, and sort in sequence with an NL step list. Each step runs deterministically in JS — no spreadsheet formula syntax to learn.

Tables sit inside the same workspace as your writing, research, and AI-generated reports — so data and context stay together instead of living in a separate app.

How does the AI spreadsheet builder work?

You describe the table you need in plain English. JustJot.ai converts that description into a column schema with types (text, number, date, boolean), optional derived-column formulas, and sample rows — then renders it as a live table node in your workspace.

Can I import existing data?

Yes. You can paste a CSV, upload a file, or point the sheet builder at a research report or a set of notes. The AI extracts the relevant rows and populates the table automatically.

Do I need to know spreadsheet formulas?

No. Derived columns and multi-step transforms are written in plain English. The engine compiles them into deterministic calculations — no VLOOKUP, INDEX/MATCH, or pivot table syntax required.

How is this different from Google Sheets or Excel?

Traditional spreadsheets start blank and require you to define structure and formulas manually. JustJot.ai starts from your description or source material and builds the table for you, then keeps it connected to your notes, PDFs, and research in the same workspace.

Can I export the spreadsheet?

Yes. Any table node can be downloaded as a CSV and opened in Excel or Google Sheets in one click.

Is there a free tier?

You can build and query tables for free. Higher-volume source ingestion and advanced AI-fill features are available on paid tiers.
