AUTONOMOUS AI CODING, ON YOUR MACHINE

Parallel multi-agent builds, a private local Brain that remembers your whole codebase, review and Git built in, and team spaces that combine real work with a real git merge — on any model, hosted or your own hardware.

FROM LEXER TO KLEX

Klexer
Code
The compiler's first pass — reads raw code and breaks it into meaning, token by token.
Add the K: a system that doesn't just read your code — it reasons, builds, and remembers.
The short name you'll type a hundred times a day.
Core

THE ENGINE

01

Hyperloop

Describe a goal. It fans out into up to seven parallel agents, each with an automatic verify → repair loop, and gives a plain-language "what changed, what's next" summary as each finishes.

02

The Brain

Cross-project memory learns your stack once, recalls every past session, reuses what worked, and ships with 100+ skills you invoke with a slash.

03

Any Model

34 providers built in — and your own hardware. Run Ollama or LM Studio locally, or point at a machine on your LAN.

04

Review & Git

A dedicated review panel stays fast across hundreds of files, click-to-comment diffs collect into the chat, and commit → push → open-PR happens without leaving the app.

Only in Klexer

TEACH YOUR BRAIN

A private, local library of your skills, tools, docs and notes — recalled automatically when relevant. Nothing leaves this machine.

AROUND THE WORKFLOW

05

Codebase Graph

An interactive map of how a project's symbols reference each other — Force, 3D, Ring, and Tree layouts.

06

Automations

Schedule recurring agent runs in the background; they land in a human-in-the-loop review state, with auto-archiving and retry-with-backoff.

07

Voice & Companion

A mic for voice input and a live avatar that reacts to the session — narrate, mute, collapse to a bar, or pop it out as its own floating window.

08

Desktop Polish

SSE streaming, inline tool-call visualization, undo/redo of an agent turn, a command palette, system tray, and auto-updates.

The team behind every task

POWERED BY SEVEN SPECIALISTS

Each agent is an expert with its own tools, memory, and verification loop.

The war room

MEET THE AGENTS

Each comes with a guided path, real one-click MCP connectors, and vetted example repos.

Any model, including your own hardware

RUN IT ON WHATEVER YOU TRUST

34 built-in providers — plus local and LAN models. Run a model on your own machine, or point at another box on your network.

CODE TOGETHER, LOCALLY

Shared workspaces where your team writes, reviews, and ships — without sending code to someone else's server.

Team Notebooks, shared Brain knowledge, and real-time presence — all running on your own infrastructure.

Team Notebooks Shared Brain Role Permissions Real-time Sync

Real-time collaborative AI coding — what Google Labs is experimenting with, Klexer ships for production.

Wired Jack

Share what you built — a thumbnail, your GitHub repo, a demo — and message other builders about their work.

Share Skills

Publish your custom skills — prompt chains, tool configs, agent setups — for anyone to install in one click.

Share Brains

Share Brains

Export a whole Brain pack — rules, docs, files, connectors — and let others plug your expertise into their projects.

Discover & Install

Browse the community library. Find a Brain for React, DevOps, data science — built by people who actually ship.

Pro TierPower tools

PROFORGE

Four capabilities that turn a solo tool into a team-scale production engine.

Master Session

Invite teammates, build together on a live canvas over WiFi. Trust controls, real-time file locking, shared preview.

Design Deck

Parallel agents generate several visual directions at once. Compare working previews side by side, then pick one.

Swarm

Break big goals into parallel steps, each in an isolated copy. Combine safely folds results back — no overwrites.

Fan-Out

One project → many formats. Pitch deck, mobile layout, one-pager — each agent reuses your design and branding.
