SARAH — the all-in-one place for AI agents

What it does

The whole inventory, grouped by what you are trying to get done. Nothing here is an add-on, a higher tier or a beta.

Providers and models

• Any endpointOpenAI, OpenRouter, Groq, xAI, Google, DeepSeek, Mistral, Together, Fireworks and Cerebras — or a base URL and key for anything else that speaks the OpenAI format.
• Opencode Go and Zen, built inA fresh install can talk to something before you add a single key.
• Local modelsOllama on your own machine: no key, no bill, and nothing leaving the network.
• Model per conversationEvery chat, persona and team member carries its own provider and model, so a cheap model can do the grunt work and an expensive one can do the thinking.
• Spend, visibleOverall and per-provider usage, refreshed live, so a runaway run is obvious before the invoice arrives.
• Keys kept localEntered once, stored on your machine, never logged and never handed to a model.

Chat and control

• Chat, Plan, BuildThree modes and one question: how much may the agent touch? Plan cannot write at all.
• Approvals, queueing, steering, stopSend it off, then add a correction mid-run, queue the next job, or stop everything.
• Command CenterEvery live run on one screen: what it is doing now, its full conversation, its tool calls and its files.
• Multi-ChatSeveral agents on one question at the same time. Compare the answers, or let them argue it out and read the transcript.
• Team roomsA shared room with agents and invited guests. Guests join with a code and only get the permissions you hand them.
• Chat searchFull text across every project, filtered by when a chat was last active. A hit jumps straight back to that message.
• Pop-out windowsPull a chat into its own window and dock it back when you are done.
• Spoken repliesRead answers aloud, with a persona voice and a corner avatar that reacts while SARAH works.

Projects

• A folder, plus everything around itFiles, chats, agents, skills, plugins, tasks, notes, memory, environment and activity, all scoped to the project.
• Nothing bleeds between projectsMemory and context are per-project, so a client job never leaks into your side project.
• Activity recordEvery run, tool call and file write in order, so you can see what changed and when.
• NotesFree-form notes that live with the project and stay searchable.

Files, code and running things

• Explorer and editorBrowse and edit in place, with inline ghost completion where Tab accepts the suggestion.
• Run and previewRun code and serve a website from inside the app, with the output where you can see it.
• TerminalThe agent shell commands and your own console share one dock, so nothing needs a second window.
• GitBranch, stage with checkboxes, commit, push, pull, stash, log and per-file diffs. The agent can do the same work headless.
• GitHubPull requests, issues and workflow runs without leaving SARAH.
• Remote projects over FTPPoint a project at an FTP site and edit it as if it were local.
• Regex file searchFinds the code rather than reading files one at a time.

Tools that reach outside

• Plugins.sarah bridges to Discord, mail, licensing, TOTP codes, social posting, game servers and more. Every plugin works in every project and every mode.
• Package any programPython, Node, a C binary, a curl pipeline — point SARAH at a script that already works and it becomes a named tool with arguments.
• MCPModel Context Protocol servers over stdio or HTTP, so tooling you already run elsewhere comes along.
• The webFetch pages and search for documentation instead of guessing at an API.
• Computer controlScreenshots, clicks, typing and key presses, for the jobs where driving another app is the only way through.
• Screen drawCircle the thing you mean on a screenshot and send it with the marks baked in.
• Shot StudioA screenshot gallery with an annotator, for keeping the shot that proves it works.

Skills and memory

• Skills teach judgementMarkdown files that carry your conventions — 202 ready-made in the catalogue, or write your own and keep it with the project.
• Learn by watchingWatch mode turns a job you just did into a skill, so the next run already knows.
• Memory, two scopesPer-project memory is injected automatically; global memory follows you everywhere, and only when you say so.
• Recall on demandAsk about another project and SARAH can look up what it learned there, without that memory polluting this one.
• Memory browserSee and edit every remembered fact instead of trusting the black box.

Safety nets

• Time MachineSnapshots taken automatically and on demand. Revert a file, or the whole project, to any point.
• Undo, not just revertThe last few things you asked for can be unwound one at a time.
• SandboxesDisposable copies of a workspace where an agent can try something risky, several in parallel, without touching the real project.
• Self-edit is journaledWhen SARAH rewrites its own UI, skills or plugins, every change is backed up and undoable, and a syntax error is refused before it lands.
• Plan mode is read-onlyA hard boundary rather than a promise, so looking can never turn into writing.

Sharing and automation

• Share a run or a chatPublishes a static page at /s/<id>, server-rendered with no scripts and home paths rewritten, so a link cannot leak your desktop or a token.
• SchedulesTimers that tick while the server runs, pause when it stops, and fire once if they were overdue on restart.
• Task boardTo do, doing, done over the project task file the agent also reads. Repeating tasks roll over when ticked, so the weekly job never vanishes.
• Auto-updateA quiet pill when a newer build is published, and a changelog before it installs.

Interface

• Split panesTwo resizable panes with layout presets; the sizes you drag are remembered.
• ThemesDark, light, or a theme you build yourself in the custom theme editor.
• Environment panelOne machine-level list of variables, so a key entered once works in every project instead of per project.

Where your data lives

• Local filesProjects are folders on your disk. Nothing is uploaded to us — the only thing that leaves is the model call you asked for.
• No accountThere is nothing to sign up for, and nothing to cancel.

Asked often, answered plainly

One-off, any amount

SARAH is free — free to download, free to keep, nothing held back behind a paywall. If it saved you an hour this week, a few quid keeps the next version coming.

Card payments go straight to Stripe. No account to create, no subscription, and SARAH never sees your card details.

What it actually pays for

• Hosting and the domainThis site, and the bandwidth for both builds every time somebody downloads one.
• Model credits for testingEvery provider integration is run against a real API before it ships, and that is paid for out of pocket.
• Hours between releasesSARAH is built by one person. A donation buys time, not features.

What you get

Nothing extra, and that is deliberate. The free build is the whole build: every provider, Chat, Plan and Build, the Command Center, Time Machine, skills and plugins. A donation buys no licence, no priority support and no badge.

If it went wrong

Donated by mistake, or the wrong amount? Email support@sarahai.co.uk and it gets returned — no argument.

Thank you. Genuinely — it is the only thing paying for the next one.

Desktop app · Your keys · Your projects

SARAH is the home your agents have been missing

SARAH is a desktop app that gives AI agents a proper place to work: chat through many providers, organise everything into projects, hand them tools, skills and plugins — and keep control with approvals, steering and a full activity record.

What SARAH actually is

Most agent tools live inside a code editor. SARAH lives outside it. It is a workshop: projects hold your files, chats, agents, skills, plugins, tasks, notes, memory and environment in one place. Agents run shell commands, read and write your project files, call plugin bridges, package new tools, and even edit SARAH itself when you ask. Chat, Plan and Build modes decide how much they may touch.

An app on your machine, not a tab

SARAH is a desktop application with a small server that runs alongside it. Both sit on your computer. A project is an ordinary folder you can open in any file manager, and agent runs happen locally — the only thing that leaves the machine is the model call you asked for. Close the app and nothing keeps working in a warehouse.

Built around projects, not files

A project is the unit of everything. Open one and you get its folder, its chats, its personas, the skills and plugins it uses, its tasks, its notes, its memory, its environment and a record of every run that touched it. Switch project and all of that switches with you, so two clients, two codebases or two hobbies never share a memory by accident.

Three modes, one dial

The only thing that changes between them is how much the agent may touch. Plan mode reads and cannot write. Chat mode uses tools but does not go editing your project. Build mode does the work — and even then, anything reckless waits at an approval until you say yes.

What it is not

• Not an editor pluginIt sits beside your editor rather than inside it, so the job can be a spreadsheet, a game server or a website as easily as code.
• Not a chat wrapperAgents get a shell, a file system, the web, plugins and the ability to drive another app. Talking is the interface, not the product.
• Not a hosted serviceNo account, no seats, no upload. Your keys, your folders, your machine.
• Not a modelSARAH does not sell tokens. It connects to the providers you already pay for, or a model running on the same computer.

"Cursor edits code. SARAH runs the whole job — files, tools, memory, publishing — and shows its working."

A day with it

You ask for something in plain language. The agent plans, then reads the files it needs. Anything that writes or runs waits for an approval if it looks risky. The Command Center shows each step as it happens, the terminal shows the shell output, and the activity record keeps the whole run. If the result is wrong, Time Machine puts the project back the way it was. That loop — ask, watch, approve, revert — is the product.

Who it suits

Anyone whose work is more than code: research, operations, writing, admin, game servers, small websites, data clean-up. If the job is “look at this, work out what to do, do it, show me”, SARAH is built for it.
