AI coding tools that remember your architecture.

Stop re-explaining your codebase every conversation. Sidelith gives Cursor and Claude long-term memory.

Developers save 8+ hours/week by not repeating context

AI tools forget between conversations

2 hours wasted

Same Bug, Third Time

You fixed this race condition yesterday. Today, Cursor suggests the same broken code because it has no memory of your fix.

30 min/day wasted

Re-explaining Architecture

"We use Redux for state." "Our API is GraphQL." "Components go in /src/ui." You type this every single conversation.

1 hr/day fixing

Breaking Patterns

AI suggests Axios when you use Fetch. Suggests class components when you use hooks. It doesn't know your style.

How Sidelith Works

Sits between you and AI to inject your project's context automatically.

Better Response

AI Forgets Your Fixes

When AI solves the same bug for the 3rd time because it forgot the previous fix.

Wastes Tokens

Loading 50 files into context because AI doesn't know where to look. Stateful context solves this by only injecting what matters.

Breaks Related Code

A fix in module A breaks module B because AI only saw part of your codebase. Sidelith provides the global graph to prevent this.

Profile.tsx

+ function updateUser() {

- // api.update() broken ref

Error: 'api' is undefined in 'Profile.tsx'

Context is Everything.

Without Sidelith, AI guesses. With Sidelith, AI knows.

app.js

// ❌ WRONG FILE: Placed in root instead of /src/routes

// ❌ OLD PATTERN: Uses callbacks instead of async/await

// ❌ LEGACY: No validation middleware

const app = express();

app.post("/pay", (req, res) => {

processPayment(req.body, (err, result) => {

if (err) return res.send(500);

res.json({ success: true });

});
