The tool platform for language models

Think of it as an app store, but for AI tools.

A universal platform that gives any language model real tools. Pick your model (Gemini, Mistral, or a local one) and add what you need.

An app store gives every phone the same apps. ToolDurus gives every model the same tools.

Bring any model, cloud or local, and your tools travel with you. Switch models mid-conversation without losing a thing. Local models even keep sensitive documents on your own machine.

Who it's for

Built for three kinds of users.

Everyday users

People who want to give large language models extra abilities for daily life: running their personal email, working with documents, or connecting to e-shops.

Organizations

Companies, nonprofits, schools, public authorities and other formal or informal groups that want to run more efficiently: unified settings, central approval of tools and models for the whole organization, privacy and security across members, plus specialized industry tools.

Developers

Builders who want to give their AI agents hands and feet for a wide range of tasks, through a simple connection over a unique token.

Getting started

Three ways in.

Everyday users

  1. Register and verify your email.
  2. Set up your account and activate the tools you want.
  3. Use them right in our chat with a wide range of the best-known LLMs, or connect them over a unique token into the providers’ own apps or your own interface (e.g. LibreChat).

Organizations

  1. Name and register your organization and its first administrator.
  2. Decide what members manage themselves and what stays unified for everyone: privacy, security, and which tools and models they can use.
  3. Add more members, and appoint further administrators if needed.
  4. Use the tools in our chat, or connect them over a unique token into providers’ apps or your own interface (e.g. LibreChat).

Developers

  1. Register and verify your email.
  2. Set up your account and activate the tools you want.
  3. Connect our tools with a unique token straight in your agents’ source code.
Under the hood

A few things worth knowing.

Built-in storage and search

A built-in cloud storage that models reach directly and operate on through tools. Text files can be vectorized, so key facts surface in seconds even across very large documents in your whole storage.

Privacy and data isolation

Optionally give each chat its own storage, where the model sees only files from the current conversation, plus control over whether it reads attachment content directly or only through tools.

Your own local models

Connect your own local language model to our chat through Ollama.
