Use tool ↗About Slatebox
Slatebox turns a prompt or an uploaded PDF into a visual you can then edit - mind maps, infographics, timelines and pitch decks on a collaborative canvas, presentable in one click. Beyond generation it works as a real-time whiteboard with shapes, notes, templates, magic share links and audio-video huddles for remote teams. Founded in 2019 and based in Minneapolis. Pricing is unusually low for the category: a free forever tier, a single-user Solo-Pro plan and a per-seat Team-Pro plan that adds custom AI personas and API access.

Pros & cons of Slatebox
Cheapest credible option in AI diagramming - $6 a month for 200 generated slates undercuts everything comparable by a wide margin. The output stays editable on a real canvas rather than dumping a static image, and PDF-to-deck is a genuinely useful path. It is a small operation, so expect fewer integrations and less polish than the big whiteboard vendors.
Pros
- Generated output stays fully editable on the canvas, not flattened to an image
- PDF upload converts into a presentable deck
- API access included in the $8 per-seat Team-Pro tier rather than sold separately
- Free forever tier with 10 AI slates before any card
Cons
- Free tier caps private slates at three
- Small vendor with a thin integration list next to Miro or Figma
- Advertised prices are annual rates, so monthly billing costs more
Best for
- Turning a PDF or a rough prompt into a first-draft diagram or deck
- Small teams that want a whiteboard with generation built in at a low price
- Remote sessions where huddles and shareable links matter
Not for
- Enterprises needing SSO, admin controls and a large integration catalogue
- Precise technical diagramming where layout must be exact
Watch out: AI slate generation is quota-limited per month (200 to 500 depending on tier), so heavy iteration on one diagram eats the allowance faster than it looks.
