Describe the change.
Gravity ships it.

Gravity is an AI assistant for software developers. Tell it in plain words what to change in your project. It reads the code, edits the files, runs the build and the tests, and shows you the result before anything is kept. It runs on your own PC.

What is Gravity?

A coding assistant that does the work, not just the talking.

Think of a capable colleague who lives inside your computer. You say what you need, for example “add a contact form” or “fix the failing tests”. Gravity opens your project, makes the changes, checks that everything still works and shows you what it did.

01

You ask in plain words

Type what you want in the chat. No special commands and no prompt tricks.

02

Gravity does the work

It reads your files, edits them across the whole project and runs your build and your tests.

03

You stay in charge

Every change is shown as a before and after. Nothing is saved until you approve it.

What it is not

It is not a chatbot you copy and paste from, and it is not autocomplete that finishes one line. It finishes the whole task.

Who it is for

Developers on Windows, especially teams with a .NET codebase, and anyone who wants AI help without sending their code to the cloud.

The difference

Answers are easy. Finished work is not.

Most AI tools hand you text to copy, paste and check yourself. Gravity makes the change in your project, tests it, and only then shows you the result.

Without Gravity
  • Paste context into a chat window
  • Copy the answer back into your files
  • Run the build and the tests yourself
  • Start over when something breaks
With Gravity

Describe the outcome once.

Gravity plans the steps, edits the files, runs the build and the tests, then retries and replans until the result is verified. If it cannot get there, it tells you why.

What you can ask it to do

Real jobs. Real requests.

These are the kinds of things people hand to Gravity. Each one has a step by step guide on the blog.

Understand an unknown codebase

Give me an overview of this solution. What does each project do and how do they depend on each other?

Read the guide →

Add a feature

Add a contact form with validation, a controller and a view that matches our layout. Then run the build.

Read the guide →

Write tests for old code

Write unit tests for PriceCalculator in the existing test project. Do not change PriceCalculator.

Read the guide →

Fix failing tests

Run dotnet test. For each failure, find the cause, fix the code and run the tests again.

Read the guide →

Refactor safely

Replace every use of LegacyClient with ApiClient. Keep the public signatures. Then build and test.

Read the guide →

Keep your code private

Run entirely on your PC with Ollama or LM Studio, so your code never leaves your machine.

Under the hood

Three layers. Zero guesswork.

What happens between your sentence and the finished, tested change.

Understand

The intent router reads your request and decides what it is: a question, a code analysis or a multi-file edit. Then it picks the right plan shape.

IntentRouter

Plan

The task planner turns intent into an explicit plan. Every step can use the output of the steps before it, so nothing is left to chance.

TaskPlanner

Execute and verify

The orchestrator runs specialist agents for files, shell, search, knowledge and MCP. When a step fails, Gravity retries and replans instead of stopping.

Orchestrator
The product

One console. An entire agent team.

Plans, diffs, builds and test runs in one place. Every action is visible and every step is verified.

In practice

Hand it a real task. Watch it finish.

Six things engineers ask Gravity to do. Each example shows what you type, the plan Gravity builds and what comes back.

You type

Replace every use of LegacyClient with ApiClient across the solution. Keep the public method signatures, then build and test.

Gravity plans

step1  search   find usages of LegacyClient
step2  file     edit $step1.files
step3  shell    dotnet build && dotnet test
step4  verify   $step3 passed

You get

Each edit appears as a diff you can approve in Review mode. If the build fails, Gravity reads the error and replans.

Read the refactoring guide

You type

Run dotnet test. Fix the failing tests in the production code, not in the tests, then run them again.

Gravity plans

step1  shell    dotnet test
step2  file     read the failing tests and the code they cover
step3  file     apply_diff to the production code
step4  shell    dotnet test
step5  verify   all green, or report why not

You get

A bounded loop that stops at a passing run, or tells you what it could not fix. Every command and result is one click away.

Read the testing guide

You type

Read Program.cs and explain the dependency injection setup.

Gravity plans

step1  file     read_file Program.cs
step2  answer   explain registrations and lifetimes

You get

A plain-language explanation in the chat. Nothing in your project changes, which makes it the safest first task.

Run your first task

You type

Create a contact form: a Razor view, a controller action that posts it and a model with validation.

Gravity plans

step1  file     list_directory Views/ and Controllers/
step2  file     write_file the model, the view and the action
step3  shell    dotnet build
step4  verify   $step3 succeeded

You get

New files that follow the conventions already in your project, shown for approval before they are written.

See more starter tasks

You type

Audit the Controllers folder for security issues.

Gravity plans

step1  agent    security_auditor (a JSON agent, read-only)
step2  file     read_file every controller
step3  report   findings with file:line references

You get

A report from a custom agent you defined in a JSON file. It cannot write files, so it can only look.

Build your own agent

You type

Add XML doc comments to the public methods of OrderService and show me the diff.

Gravity plans

step1  file     read_file OrderService.cs
step2  file     apply_diff with the comments
step3  shell    dotnet build

You get

A small, reviewable diff that touches comments only, plus a build to prove nothing else moved.

Choose how much to review

These are illustrative sessions, not recordings. What Gravity does depends on your project and on the model you connect.

Start in three steps

  1. DownloadCreate a free account and download Gravity for Windows.
  2. Connect a modelPick Ollama, LM Studio or any OpenAI-compatible provider.
  3. Describe the changeType what you want. Approve what runs.

Built for real work

Everything an engineer would ask for.

Plans you can read

Every task starts as a visible plan. Review it, change it, or let it run. Nothing happens behind your back.

Your model, your rules

Connect any OpenAI-compatible provider. Every connection remembers its own URL, key and model.

Local-first

Run Ollama or LM Studio and your code never leaves your machine.

Understands your codebase

Workspace indexing and Roslyn analysis map what a change will touch before it is made.

Agents as JSON

Drop a file into the agents folder and a new capability appears. No recompiling.

MCP ready Pro

Connect the Model Context Protocol servers you already use. Gravity becomes the brain and your tools become the hands.

Autonomous maintenance Pro

Let agents handle dependency updates, cleanups and security patches around the clock, with a full audit trail.

You are in control

You decide how much to trust it.

Three modes, one switch. Move from full autopilot to step-by-step review whenever you like.

Autopilot

Agents execute without asking. Best for work you trust and can verify.

Review

Approval is required before any destructive operation.

Assisted

Full human in the loop. You confirm every single action.

Every action is logged with diffs and walkthroughs, so you can always see what changed and why.

Coming next

Gravity 2 is on the way.

Gravity today is the engine. Gravity 2 is where it goes next: agent swarms that explore, edit and verify in parallel, and codebases that heal themselves while you focus on intent.

Questions

Everything you need to know.

Is Gravity really free to download?

Yes. Create a free account, sign in and download. There is no payment step and no card. Pro adds extra features inside the app.

Is my code sent to external AI providers?

Only if you choose a cloud provider. With local models such as Ollama or LM Studio, your code never leaves your machine. Gravity is local-first by design.

What is the difference between Free and Pro?

Free includes the core multi-agent engine and every approval mode. Pro adds MCP protocol integration, advanced RAG workspace indexing, 24/7 autonomous maintenance and priority support.

What happens after the 7-day trial?

Your account moves to the Free plan automatically. You keep the app and the core engine. Pro-only features switch off until you upgrade.

Which systems does Gravity run on?

The desktop app runs on Windows 10 and 11 (64-bit). It runs on your own machine, so your workspace and your data stay under your control.

How does Pro licensing work?

Pro costs 29€ +VAT for the first year, then 100€ per year for updates and support. Each license can be activated on up to 3 machines, and there is a 14-day money-back guarantee.
