PromptBlocks is your home for AI conversations. It combines a searchable prompt library, reusable compositions for workflows, projects to organize your work, and a chat interface where the AI remembers your context. Everything works together to make AI more useful for your daily work.

Projects let you organize related chats into focused workspaces. When you chat inside a project, the AI automatically knows your project description and attached files. The AI also builds memory over time, remembering important facts from your conversations. It's like giving the AI context about what you're working on without having to explain it every time.

As you chat within a project, PromptBlocks automatically extracts important facts from your conversations and saves them as project memories. The AI can then reference these memories in future chats, so it remembers things like your preferences, decisions, and key information without you having to repeat yourself.

Yes, and this is one of the most powerful ways to use PromptBlocks. Working on Client A and realize you need context from Client B? Switch projects mid-chat, pull in what you need, and switch back. Your different workstreams can inform each other without copy-pasting or re-explaining. The context travels with you.

When you attach files to a project, PromptBlocks indexes their contents. When you ask a question, the AI automatically searches your files for relevant information and includes it in the response. You'll see a 'Sources' section citing which files were used. It's like giving the AI access to your reference documents without manually attaching them to every chat.

Sign up for free and start chatting immediately with our included AI models. You get 5 premium AI messages and 200 basic messages per day. Create prompts to save text you use often, build compositions for repeatable workflows, and organize your work with projects. Upgrade to Pro for unlimited usage.

Compositions combine prompts, regular text, and dynamic values (like today's date) into reusable workflows. They're perfect for daily check-ins, weekly reviews, or any routine you repeat. Build a composition once, then load it anytime to run the same workflow with fresh, up-to-date information.

Create prompts with variables using double curly braces (e.g., {{topic}} or {{tone}}). When you use these prompts, you fill in the values, making one prompt work for many situations. It's like having a template you can customize every time you use it.

Type '@' in any chat to see your saved prompts. Start typing to filter, then select one to insert it. The prompt appears as a badge in your message. If it has variables, click the badge to fill them in. It's the fastest way to use your prompts without leaving the conversation.

PromptBlocks includes the latest models from OpenAI (ChatGPT), Anthropic (Claude), Google (Gemini), and Grok, plus basic models for everyday tasks. Free users get 5 premium messages and 200 basic messages per day. Pro users get unlimited access to all models.
