Elmo vs Notra
Elmo is an open-source, self-hostable alternative to Notra, an AI visibility tracking tool. Both measure how AI answer engines describe your brand, but Elmo ships every line of code, runs on your own infrastructure, and is free to self-host — so your data stays yours and each metric is independently verifiable.
The short version
Notra was open source until October 2026, then took its code private. Elmo is MIT-licensed, so that can't happen to you.
Elmo
Open-source AEO platform. Self-host for free, forever. Track AI visibility across ChatGPT, Claude, and Google AI Overviews with full transparency.
Notra
AI content engine turned AI visibility platform, formerly open source
About Notra
Notra started in January 2026 as an AI content engine that drafts changelogs and launch posts from GitHub, Linear, and Slack, and added AI visibility tracking in August 2026. It tracks ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews with web search, and queries Grok, DeepSeek, and Meta's models without it. Its code was public under the AGPL-3.0 license until mid-October 2026, when the repository was taken private.
Popularity grade: F
- Went from AGPL open source to closed source in October 2026
- Content Studio for changelogs and launch posts alongside tracking
- REST API, MCP server, and CLI
