Short answer: Not currently. Segwise does not offer pre-flight (pre-launch) creative testing.
What Segwise needs to analyse a creative: the creative must already be running on one of your connected ad networks, and it needs enough live performance data (spend, impressions, results) for Segwise to detect reliable patterns and insights.
Why: Segwise's insights come from mapping your creative elements (tags) to real performance outcomes from your ad data. If a creative hasn't run, there's no performance data to learn from — so uploading creative files from your computer to get a "will this work?" verdict before launch isn't something Segwise can do today.
What Segwise does do: once your creatives are live and have enough data, Segwise automatically tags them, links those tags to performance, flags early winners and creative fatigue, surfaces winning patterns, and can generate new creatives based on what's already working.
If pre-launch testing is important for your team, let your Segwise contact know — but it isn't available today.
