PyGPT is a desktop AI assistant covering chat, agents, web search, Python execution, speech in and out, plugins and long-term memory. The README is unusually direct about the key question: it 'utilizes the user's own API key', connecting to OpenAI, Google, Anthropic, xAI, Perplexity, Mistral, OpenRouter and others with credentials you hold, and it notes that local models served through Ollama need no external key at all. MIT, confirmed by reading the LICENSE rather than trusting GitHub's detector, which reports the repository as unlicensed.

Why this trust score (79/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 23/25: The key is held on your own device.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under MIT, so anyone can check how the key is handled.
  • Privacy 8/15: Local-first: it works without sending your data anywhere. Analytics or error-reporting libraries are present; what they send was not established.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

What was checked

Verification tier RESEARCH_ASSISTED, derived from the evidence below and not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
  • [REPORTED · SOURCE_SCAN] References PostHog, so some analytics or error reporting is present. This scan cannot tell whether it is opt-in or what it sends. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-09-15, about 0 month(s) ago. source

How your API key is handled

Your API key is stored locally on your device. Requests are sent directly to the AI provider.

Setup

Open settings, paste your provider API key, choose a model, and start. The key stays on your device.
