From sales and support to internal operations: build your own agents or start with ready-made ones.
With every task, they learn more about your business and work more effectively.
Pick a ready-made agent, build your own, or get a turnkey solution. Everything you create stays with your company: agents accumulate experience, understand your processes better and help automate more and more of the work.
“Give me something that just works”
Pick an agent from the library and point it at your task. First results within a week — no heavy rollout, no endless setup.

Build agents around your processes: on your own, or with the built-in assistant that asks a few questions and sets the agent up for you. Your keys, your data, your scenarios.

We design, launch and maintain agents around your processes — in our cloud or on your infrastructure. Data, credentials and business logic stay inside your perimeter.
Write to us →Start with a role your business already understands: sales, support, documents, operations, finance or management. Extella helps you quickly assemble an agent for the scenario, connect your channels and adapt it to the way you work.
Qualifies inbound leads, answers first questions, books meetings and keeps the history of every conversation.
Handles first-line requests, answers from your knowledge base and hands complex cases to a human — with full context attached.
Collects data, updates statuses, prepares reports and reminds the team about tasks. No manual routine.
Reviews documents against your rules, flags risks and shows which clauses need a lawyer's attention.
Reconciles invoices, contracts and emails, helps spot discrepancies and gets the numbers ready for review.
Gathers project statuses, records blockers and prepares a short report before the meeting.
Knowledge that lives outside the head: in language, books, tools, technology and cultural practice. Stewart and Cohen described extelligence as external cultural capital — the counterpart human intelligence interacts with.

Extella carries this idea into the digital world: knowledge, rules and repeatable solutions become a layer of memory and execution — a system that remembers context, acts by your rules and turns experience into ready-to-run tools.
An agent's work is split into four layers: how it acts, what it remembers, what it stores and what it can execute. Rules survive between sessions, context stays at hand, credentials live separately — and solved tasks become tools you can run again.
How agents act. Say it once — the rule applies in every session, shared across agents or specific to one. Nothing needs explaining twice.
What agents remember. Not chat history — knowledge: your processes, clients, preferences and decisions. Retrieved by meaning, automatically.
What agents store. An encrypted vault for keys, credentials and configuration. Data lives apart from chat and model memory, never lands in logs or exports — and an agent gets only the access its task requires.
What agents can do. Isolated execution modules: any language, any library, any tool. Solved once — versioned and working forever.
Works where your data lives. Extella executes tasks on your device or server. Nothing has to move into someone else's environment: files, keys, models and tools stay inside your perimeter.
Any provider, or fully local. Bring your own keys for OpenAI, Anthropic, Google, xAI and other providers. Or run fully local via Ollama.
CSPL (Custom Scripting / Processing Layer), Extella’s own language, makes repeated tasks cheaper and more reliable: the model declares the “what”, the execution layer knows the “how”. On similar tasks that’s up to 15× fewer tokens.
More about CSPL →Instead of a dozen scattered tools — one system: models, agents, data and tools working together, with no constant switching between services.

Extella remembers how a task was done and turns it into a ready-made tool. Next time, just run it again: faster, cheaper, zero setup.
Say what you need in plain words. No diagrams, nodes or code.
The system works with files, APIs, documents and data on your device or server. It doesn't explain how to do it — it does it.
The finished solution lands in your library. Run it again with one command, put it on a schedule, or share it with the team.
