Synapse AI — your AI browser agent

An AI-powered Chrome / Edge / Brave extension that turns any web page into an autonomous, controllable workspace. It runs an observe → plan → execute → verify loop: it reads the live page, an AI model picks one action, the extension performs it, checks the result, and repeats until your objective is done. Works out of the box — no API key required.

What Synapse AI can do

A single extension that combines browser automation, AI content generation, and workflow intelligence.

Autonomous web automation

Navigate, click, type, extract, and fill forms on any page. The agent plans each step and verifies the result before continuing.

AI content generation

Generate posts, replies, and copy in your brand voice. Built for Facebook page management and social operating workflows.

Vision fallback

When the DOM is empty or unclear, Synapse understands a screenshot of the page so automation never gets stuck.

Self-learning memory

Model rotation, failover, and a technical HUD keep tasks reliable. Outcomes feed a memory that improves future runs.

No key required

AI routing goes through a secure hosted proxy, so the extension works immediately — no NVIDIA key to configure.

Site-specific playbooks

Ready-made workflows for ChatGPT, Gmail, YouTube, Facebook, Google, LinkedIn, GitHub, Canva and more.

An agent loop you can steer

Type an objective and Synapse does the work — step by step, transparently.

1

Observe

The extension reads the live page — its DOM, forms, and visible content — to understand the current state.

2

Plan

An AI model (NVIDIA NIM Nemotron / Llama / VILA) picks the single best next action toward your goal.

3

Execute

Synapse performs the action — click, type, extract, fill — directly on the page.

4

Verify

It checks the result and loops until the objective is complete. Use Pause / Stop in the HUD to stay in control.
