Filler Chat Message Generator
A filler chat message generator drops a coherent, alternating conversation into your messaging mockup — real dialogue shape, not lorem ipsum in speech bubbles. Each output is assembled from short scripted exchanges: two speakers take turns (Alex and Jordan, or You and Support in the help-desk tone), so bubble alignment, sender labels, and thread rhythm all read correctly in a design review. Three tones cover the common cases. Casual is friends making plans or talking about a show; Professional is coworkers rescheduling calls and chasing a report; Customer Support pairs customer questions — missing orders, refunds, tracking — with agent replies. Each run draws two-message exchanges without replacement from a 15-exchange pool per tone and trims to your count — set 4 for a compact notification preview or 30 for a full thread. Know the limits: exchanges land in random order, so each question-and-reply pair is coherent on its own but a long thread reads as plausible chatter rather than one continuous storyline, and an odd count ends mid-exchange on an unanswered line. Fine for a mockup; reorder or trim by hand if a reviewer will read the whole thread closely.

Use Cases
- •Populating Figma chat UI frames with alternating two-party dialogue before real content is ready
- •Filling app store screenshots with customer support exchanges that show the product's core use case
- •Seeding a React chat component's mock JSON fixture to test bubble alignment and overflow rendering
- •Demoing a live-chat widget to stakeholders in Notion or a Figma prototype with natural-sounding threads
- •Generating professional-tone placeholder messages for an enterprise internal messaging tool pitch deck
Tips
- →Generate two separate batches at different message counts and combine them to simulate a longer scrollable thread with more natural variation.
- →Use Customer Support tone specifically when mocking help widgets — its structured greeting and resolution language makes the widget feel production-ready to stakeholders.
- →If your UI shows message timestamps, generate 8-10 messages so you have enough content to demonstrate grouped timestamp headers between message clusters.
- →Avoid mixing tones in the same mockup frame — a Casual opener followed by Professional replies creates a jarring inconsistency reviewers will notice.
- →For A/B mockup comparisons, generate the same message count in two different tones and place them side-by-side to show how tone changes the perceived audience for a feature.
- →When testing chat bubble max-width and text wrapping, regenerate a few times until you get at least two messages that are noticeably longer than the others.
FAQ
how do I get fake chat messages that don't look obviously fake in a prototype
Match the tone to the product: Casual for social apps, Professional for workplace tools, Customer Support for help widgets. Each thread alternates two speakers with natural back-and-forth — questions, confirmations, short replies — so bubbles, sender labels, and thread rhythm read like a real conversation.
can I use generated chat placeholders directly in a React component or JSON fixture
Yes. Each line is formatted 'Name: message' — Alex and Jordan, or You and Support — so a quick split on the first colon maps cleanly to sender and text fields. The content is fictional and safe to commit as test data.
what's the difference between casual and customer support tone for chat mockups
Casual produces informal exchanges between two friends — plans, small talk. Customer Support pairs customer questions with agent replies — missing orders, refunds, shipping — with speakers labeled You and Support instead of names. Use support tone when demoing ticketing or live-chat interfaces.
why doesn't the thread tell one continuous story
Each run draws two-message exchanges at random, without replacement, from a pool of 15 per tone, so the thread is a sequence of self-contained question-and-reply beats rather than a single scripted arc — and no exchange repeats within a run. Consecutive exchanges can change subject, which reads fine as ambient chatter in a mockup. If you need a tight narrative, reorder or cut lines by hand.
