Elmo vs Promptwatch
Elmo is an open-source, self-hostable alternative to Promptwatch, 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
Promptwatch doesn't list Microsoft Copilot among its engines. Elmo has all of that, and it's free to self-host.

Why choose Elmo over Promptwatch?
Open source and transparent
Every line of code is open. You can verify exactly how your visibility data is collected, calculated, and presented. No black boxes.
Self-host for free, forever
Run Elmo on your own infrastructure. The core platform is free and always will be, and Elmo Cloud is there if you would rather not run it yourself.
Your data, in your stack
Pull every metric, sentiment included, into your own code with the REST API and TypeScript and Python SDKs, or ask Claude Code and Cursor about it over MCP. Export, fork, or migrate at any time.
Built to last
Bootstrapped and sustainable. No investors pushing towards dark patterns. We'll outlast the companies taking too much VC money.
