just words - boost user growth with optimized product copy

tldr: just words uses AI to optimize product copy for large companies. We built similar systems at Twitter and Pinterest, boosting user growth by 20%.

We help companies scientifically pick the right words for their product copy (eg: landing page titles, notifications). Instead of trying a new title for your website every few days, just words objectively evaluates copies based on performance and fine tunes future copies based on experiment insights.

We first observed this pain at Twitter. Our teams started building internal tooling to gain experimentation velocity on copy. We then saw the same problem at Reddit and Pinterest. Now, having spent 9 years collectively in the growth space, we believe there is enough evidence for this approach across the industry.

❌ the problem

1. It takes effort to come up with good copy (eg: for your landing page, email subjects). It’s work to scientifically measure which copy resonates the best with your users. Copies are hard-coded, either directly in code or in config files. As a result, every small change requires redeployment of the app. One copy change becomes a 2-week project on an engineer’s roadmap, and companies are only able to prioritize a small number of changes a year.

2. There is no “copy repository”, so companies lose track of the history of changes on a particular string, learnings from past experiments, and their occurrences across the product. With no holistic view, product teams make copy changes based on “vibes”. There is no way to fine-tune the next iterations of copy based on patterns obtained from previous experiments.

3. No context-based optimization: Companies either test 1 copy change at a time for all users, or rotate a pool of copies randomly. In an ideal world, they should be able to present the best copy to different users based on their context.

✨ our solution

Always show users the best copy through continuous experimentation and fine-tuning.

⚙️ how it works

1. no code A/B testing: Performance test many variations of a copy with 1 click.

2. copy versioning: Think Github for copy iterations. See the entire history and performance of copies across product features.

3. copy fine-tuning: Get tailored insights to fine-tune next iterations.

4. personalized copy rotation: Dynamically rotate different variations across users.
