Lettertrace - Track your AI visibility for free (using your own API keys!)

by•
Lettertrace measures how often Claude, ChatGPT, and Gemini mention your company. But there's a catch: it's free, developer-first, bring-your-own-key, and open source.

How accurate the visibility and the sentiment tracking is compared with the paid tools SEMrush, Profound etc?

Congrats on the launch! Really like the open-source + BYOK approach.

How do you decide which prompts are most relevant to track for a company?

Congratulations

Maker

 Thanks a lot!

 thank you !!!

Good luck with the launch

 thank you so much !

Would love to have a single docker run command so I can test it on my own infra in one click. (The current github repo doesnt have the Dockerfile / image either.)

Anyway Thanks for building it, love opensource.

 We could make that happen. could you help with that?

   absolutely! I’ll get this up and running today and then follow up here :)

   Added! There's a Dockerfile and a published image now. Setup's in the README:

Congratulations on the launch ! The SEO community needs more such open source and free to use products (like openSEO). Love this and thanks for launching (Profound made a hole in my pocket!)

 hahaha i read you.

Incredible team with deep domain expertise here! Have already enjoyed using their product

 Thank you :))

 thank you Ben!! We love work with ya'll

 thanks so much Ben!

Congratulations! It’s so nice that it’s open source:) Are you planning to include European models like Mistral ?

Love that the CLI does the heavy lifting instead of another dashboard I have to log into. Do you store historical runs to see visibility trending over months?

 yep that's built in

But how this will work AEO tracking is not done using api calls? Because API call results and actual platform results differ a lot. Good AEO platforms use actual accounts run using browser automation.
