Latest News
Jaber Said announced the launch of Prompt Builder, a block-based editor/workspace intended to replace scattered prompt notes and copy-paste workflows.
The builder’s technical launch write-up documented its Next.js 14, Supabase, Stripe, Zustand, React Query, Tailwind/shadcn UI, and @dnd-kit stack, along with planned team workspaces, API access, a Chrome extension, and a template marketplace.
Prompt Builder updated its Privacy Policy and Terms of Service, describing Google OAuth, Stripe billing, account/data handling, and the service’s Free and Pro plans.
Products & Services
A browser-based, block-based prompt IDE for composing, organizing, previewing, testing, exporting, and sharing AI prompts.
A free public library of more than 7,000 copy-ready, modular prompt templates with categories, subcategories, structured blocks, and variables for major AI models.
Paid tier adding unlimited prompts, blocks, folders, and sharing plus variables, AI and multi-model testing, A/B comparison, editable AI outputs, import/export, translation, secure sharing, analytics, and advanced diagrams.
Market Position
Prompt Builder positions itself as a block-based prompt IDE and workflow layer rather than a plain text editor, notes app, or prompt marketplace. Its own comparison names PromptBase and Notion as alternatives: PromptBase is characterized as a buying/selling marketplace, while Notion is general-purpose note-taking; Prompt Builder differentiates with modular blocks, variables, live preview, direct model testing, multilingual tools, and protected sharing.
Leadership
Founders
Jaber Said
Full-stack engineer who describes himself as building bridges between imagination and reality; he personally built Prompt Builder and writes about its Next.js, Supabase, Stripe, Tailwind/shadcn UI, and drag-and-drop implementation.
Founding Story
Jaber Said says he started Prompt Builder after repeatedly losing carefully crafted prompts and spending too much time copy-pasting and rewriting prompts scattered across notes, documents, and chats. The initial vision was to treat prompts like LEGO blocks: independently editable, draggable, reusable, toggleable for testing, and easy to share.
Business Model
Revenue Model
Freemium SaaS subscription. A permanently free plan provides limited prompt-building, sharing, voice-input, and template-library access; Pro subscriptions monetize unlimited usage and advanced workflow, testing, sharing, analytics, translation, and import/export capabilities.
Pricing Tiers
3 saved prompts, 5 blocks per prompt, 2 folders, 5 share links, voice input, block editor, live preview, and access to the public template library.
Unlimited prompts, blocks, folders, and sharing; variables; AI testing and multi-model comparison; editable outputs; import/export; secure sharing; analytics; translation; and advanced diagrams.
Annual Pro billing with the same Pro workflow feature set.
