The Verdict
Exa is built for ai developers and researchers, with a focus on neural-search and content-retrieval. Greptile targets developer tool builders and engineering teams and leads with codebase-indexing and natural-language-queries.
Both tools come in at similar price points ($100/mo for Exa, $100/mo for Greptile), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Greptile offers broader built-in capabilities (7 features vs 6), while Exa takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
