"Coco Alemana feels like it was built by someone who does this work. Native, quick, and it stays out of your way. I don't recommend many tools. This is one I'd hand to any data person on a Mac."

John Humphrey VP Data, Mozilla

Now picture the same week with Coco.

Coco finishes before Tableau opens.

Three date formats in one column. Two ways to fix it.

Conversational Intelligence

The AI agent Tableau keeps behind Cloud+ is in the download.

Type what you want and get it, whether that's a count, a chart, or a new column derived from three others. It works on the file in front of you, not a copy of it somewhere else.

Clean it with a sentence.

Ask Coco to standardize inconsistent values, tidy up categories or filter the data. Review the changes as part of your workflow.

Find out why the number's wrong.

Ask Coco to look into unexpected values. It uses your change history for context and helps you fix the cause.

Sandboxed by default.

It can't delete or overwrite your source data. Its edits are marked in your change history, and ⌘Z undoes the last batch.

Visual editor + SQL + agent

Click it, query it, or ask for it

Prep gives you a canvas of steps and a custom SQL box at the start. Coco runs clicks, SQL and the agent on the same dataset, in any order. Query, fix a column by hand, ask Coco to tidy the categories, query again. Every step is recorded and your source is never touched.

Click Fix a column by hand

Inline, instant editing. Quickly change hundreds, or millions of problematic values by editing the table directly.
SQL Query the same dataset

Switch between visual changes, and custom SQL statements that run directly against your changes.
Ask Have Coco tidy the categories

Ask Coco to standardize inconsistent values, tidy up categories, or filter your data.

Questions

Frequently asked questions

Is Coco cheaper than Tableau?

It depends on what you're paying for. Coco is billed monthly, with the AI agent included. Tableau's Creator seat is billed yearly, and its Prep agent needs Cloud+. Try Coco free, with no card, and compare on your own data.

Do I need a Salesforce account, Data Cloud, or a call with sales to use the AI?

No, no, and no. Open a file and type. The only one you'll be talking to is Coco.

Where does my data go?

Your files stay on your disk. Coco Alemana is a native Mac app that processes everything locally, and your warehouse credentials never leave your machine. If you use the conversational feature, part of your data is sent to answer the question. We don't retain it and we don't train on it.

Is this Windows-compatible?

Not yet. Mac only right now, but Windows is coming soon. Join the Windows waitlist to get instant access when it launches.

Your Tableau renewal can wait. Try this on your data today.
