WebSparks

WebSparks has a free tier, and paid plans are billed yearly at $162 for Starter and $702 for Plus. The Pro plan is listed at $2,160 a year.

WebSparks is an AI app builder and website builder that turns chat prompts into working websites and applications, so you describe what you want and refine it in conversation.

The free plan lets you chat, generate content and keep up to five projects.

It also includes the Crawler, the Sketchboard and standard voice mode.

File upload is limited, and daily usage limits sit under an overall monthly cap, so heavy users will hit the ceiling quickly.

Starter removes the daily limits, raises messaging limits tenfold, and adds advanced voice mode, a Prompt Enhancer, unlimited code export and limited pushing from GitHub.

Plus adds high speed access, far higher messaging and attachment limits, and an Advanced Prompt Enhancer.

Pro has unlimited messaging, unlimited pushes to GitHub, an expanded context window for longer inputs, and ongoing account management with enhanced support.

The jump between tiers is steep, so start free and see how far the cap takes you.
