SendEmail

  • Features
A built-in Base44 function that sends an email (such as a confirmation, alert, or notification) to registered users of your app without needing a separate email service account.

server

  • Core
A computer that runs services for other computers over a network, such as a website, a database or an AI model. It can sit in your organisation's data centre or be rented in the cloud.

Also known as: servers

Server actions

  • Concepts
Functions that run on the server rather than in the browser, used in v0's Next.js projects to handle form submissions, database writes, and other backend tasks.

service account

  • Core
An account that belongs to a system or a team rather than a person, used by automations to sign in. Give it only the access its job needs, and name who is responsible for it.

Also known as: functional account, technical account, bot account

service tier

  • Features
A setting on each API request that controls processing priority — Priority (dedicated endpoints only) is highest, Default is standard, Auto uses the highest available tier, and Flex is lowest-priority for non-urgent tasks.

session

  • Concepts
One continuous conversation with opencode, including all your messages, the AI's replies, and any file changes made during that exchange.

sf.write

  • Functions
A function from the SoundFile library that saves an array of audio samples to a .wav file.

shadow AI

  • Core
Staff using AI tools the organisation hasn't approved, often with work data in private accounts. It usually means the approved tools don't yet meet people's needs.

shared endpoint

  • Concepts
The standard public API where many customers share the same hardware; easier to get started with but performance may vary under high demand.

shot size

  • Parameters
A setting that tells the video generator how close or far the camera appears to be from the subject.

Show Citations

  • Concepts
A toggle under an answer that reveals which uploaded files it was drawn from, so you can verify each claim against the source.

Sidebar

  • Interface
Panel on the left side of the app that lists all your notebooks for quick switching.

single sign-on

  • Core
Logging in to many services with one organisation account, such as your university or company login. It lets IT grant and remove access in one place.

Also known as: SSO, single sign on

skill

  • Concepts
A reusable instruction set stored in a SKILL.md file that agents can load on demand, like a reference manual the AI can consult for a specific topic or workflow.

skill · Concepts

A reusable capability you give an agent: a folder with a SKILL.md the agent loads only when a task matches, so specialised know-how does not clutter every session.

SKILL.md

  • Files & config
The required file inside a Skills package that contains both YAML metadata (so the agent knows when to load the skill) and Markdown instructions (telling it what to do).
3 other definitions

SKILL.md · Files & config

A saved skill — a short file describing a procedure the agent loads only when it is relevant.

SKILL.md · Files & config

A saved skill — a short file describing a procedure the agent learned once and can repeat.

SKILL.md · Files & config

The one required file in a skill: YAML frontmatter (a name and a description) followed by Markdown instructions the agent follows.

Skills

  • Concepts
Packaged instruction files that teach an agent how to handle a specific kind of task; you can add them globally or per project.

Also known as: skills

skills · Concepts

Add-on capabilities you install (e.g. from clawhub.ai) that extend OpenClaw to work with external services such as Gmail or GitHub.

slash command

  • Concepts
A saved prompt you invoke by name (e.g. /review) instead of retyping it — a shortcut, not loaded-on-demand like a skill.

slashes (e.g., /kɒˈkoʊroʊ/)

  • Syntax
Characters placed around an IPA string to tell Kokoro to use those phonemes instead of guessing the pronunciation.

snapshot

  • Features
A save-point opencode automatically tracks as the AI makes file changes, used by the undo system to restore your code if you want to reverse the AI's edits.

sns.clustermap

  • Concepts
A function from the seaborn visualisation library that draws a heatmap with rows and columns automatically reordered so that similar values cluster together.

sns.heatmap(...)

  • Concepts
A seaborn function that draws a colour-coded grid where each cell's colour represents a numeric value — useful for spotting patterns across many samples or genes at once.

SOC 2 Type II

  • Certifications
A report that verifies a service provider’s controls for security, availability, and privacy over time.

Sonar

  • Concepts
Perplexity's own family of AI models, optimised for fast, accurate web-grounded answers; the base Sonar model is the default search model, while Sonar Pro and Sonar Deep Research handle progressively more complex tasks.

Sonar API

  • Concepts
A developer interface that lets programmers embed Perplexity's web-grounded search capability into their own applications, using the same request format as the OpenAI API.

SOP

  • Core
Standard operating procedure: a written step-by-step instruction for a routine task, so everyone does it the same way. Labs and quality systems rely on them.

Also known as: standard operating procedure, standard operating procedures

Sora 2 app

  • Interface
The mobile or web application where you create, edit, and generate AI videos with Sora’s tools.

source ~/.bashrc

  • Install
Reload your shell’s settings so a newly installed command is found without reopening the terminal.

source-available licence

  • Core
A licence that lets you read and often self-host the code but restricts some uses, such as selling it as a hosted service. It looks like open source but gives you fewer rights.

Also known as: source-available, source-available license

Space Explorer

  • Features
The file-browser panel in KNIME where you navigate and manage your workflows, folders, components, and data files.

Spaces

  • Features
Collaborative workspaces inside Perplexity where you can group related threads, write custom instructions that apply to every search, and invite teammates to contribute.

Spaces Collaboration

  • Collaboration
Shared workspaces where multiple users can add chats, files, and prompts to co‑author projects in real time.

Spark Page

  • Features
The Deep Research tool that creates a full web‑page with sections, citations and an AI copilot from a single query.

Speaker

  • Features
Named voice profile (up to four) that reads lines in a generated podcast.

Speaker Boost

  • Settings
An optional toggle that makes the chosen voice sound louder and clearer in the final audio.

Speakly

  • Tools
A voice‑to‑text tool that cleans up spoken input into a clear written prompt for GenSpark agents.

spending limit

  • Core
The most you allow an account to spend on a paid service each month. Set one before you connect a paid API key to any tool, so a loop or a mistake can't run up a large bill.

Also known as: spending ceiling, spend limit, budget cap

SQL

  • Core
Structured Query Language: the standard language for asking a database questions and changing its data, for example listing all orders from last week.

Also known as: Structured Query Language

SQLite

  • Components
An embedded relational database bundled with Gitea so you can run it without setting up a separate database server.

SSH public key

  • Authentication
A cryptographic key you paste into the Hetzner creation form so you can log in without a password.

Sticky note

  • Features
A text annotation you can place anywhere on the canvas to explain what part of a workflow does, without affecting how it runs.
