Yes. Whimsical's Free plan includes unlimited docs and unlimited guests. On the Free plan you can add up to 50 new doc blocks per month, where a block is a single piece of content such as a paragraph, a heading, a list item, an image, or an embed. The Pro plan removes that limit for $12 per editor per month, or $10 per month when billed annually.

Yes. You can format a doc with Markdown as you type, paste Markdown straight into a doc, and drop Markdown files onto a folder to turn them into docs. You can also export a doc as Markdown from the Share menu.

Yes. You can create a board inside a doc or embed an existing one, and it shows as a preview in the doc. Embedded boards stay in sync with the original, so a flowchart, wireframe, or mind map in a doc is always current.

You can embed content from Figma, Airtable, Loom, YouTube, Vimeo, Canva, Hex, and CodePen in a Whimsical doc, as well as Whimsical boards. You can also upload images.

Yes. Whimsical docs are collaborative in real time, so several people can write in the same doc and see each other's changes as they happen. You can comment on a doc, share it by link with view, comment, or edit access, and restore earlier versions from version history.

Yes. Whimsical docs have code blocks with syntax highlighting, along with headings, lists, toggle lists, and collapsible headings. Focus mode gives you a full-screen writing view, and the table of contents updates automatically.
