HeraldYour team's knowledge,
always up to date
Herald deploys AI agents that capture, organize and maintain your organization's knowledge — automatically. Every interaction makes your knowledge base smarter.
See how knowledge flows
AI agents capture information from every channel, while the Librarian organizes and maintains your knowledge base automatically.
Everything you need to orchestrate
Herald gives you the building blocks to create sophisticated AI workflows — from simple chatbots to complex multi-agent pipelines.
AI Librarian
The heart of Herald. An AI agent that automatically curates your knowledge base — organizing, deduplicating, and keeping information fresh after every interaction.
Hybrid Knowledge Search
Semantic understanding meets keyword precision. Your agents find the right information instantly through vector similarity and full-text search combined via Reciprocal Rank Fusion.
Auto Prompt Optimization
A dedicated AI compiles optimized prompts for each agent from your knowledge base content. Version history lets you track changes and rollback anytime.
Visual Agent Architecture
Design multi-agent workflows in a drag-and-drop graph editor. Each agent has its own role, LLM model, tools, and knowledge scope.
Multi-Channel Ingestion
Capture knowledge from every source — APIs, webhooks, Gmail, and more. Gateway nodes route information to the right agents automatically.
Human in the Loop
Agents escalate to the right person when needed. Your team responds via an inbox, and the knowledge captured feeds back into the system.
Up and running in minutes
Three steps to a knowledge base that maintains itself.
Connect your sources
Plug in your information channels — APIs, email, webhooks. Gateway nodes capture incoming data and route it to the right agents.
Design your agent tree
Build your processing pipeline visually. Assign LLM models, knowledge bases, and tools to each agent — the Librarian handles curation automatically.
Watch it learn
Every interaction enriches your knowledge base. The Librarian deduplicates, cross-references and keeps everything fresh — your team just works.
Knowledge that works for you
Every team generates knowledge. Herald makes sure none of it gets lost — and all of it stays current.
Living Technical Documentation
Every support ticket, Slack thread and post-mortem feeds your documentation agents. The Librarian detects outdated articles, merges duplicates, and keeps your wiki accurate — no manual curation needed.
Knowledge that compounds
Teams that never lose knowledge
“We used to spend 20 hours a week updating our internal wiki. With Herald's Librarian, it maintains itself — our docs are more accurate than ever.”
“The real magic is that every customer interaction makes our knowledge base smarter. Six months in, our agents answer questions we never explicitly documented.”
“New hires used to take weeks to get up to speed. Now they ask Herald and get accurate, up-to-date answers from day one. The institutional knowledge just lives there.”
