Find the few words that matter. Try a message, notification or talk outline, then see how much space it needs.
Write a message or a short script. Your text stays in this page; the tool does not submit or save it.

Put the decision first. A name, a change and a next step often earn their space.
Make the next action obvious
A useful cue beats a full inbox.
Start with what changed and what to do next. “Alex replied. Review moved to 3 pm. Ask for the brief.” is easier to scan than a full email conversation. Keep the full source available on the connected device when someone needs the detail.
For a talk, try one idea per card. For chat, keep the sender and the meaningful part of the message together. Use the preview to compare a full sentence with a shorter cue; then test the result on the device you intend to use.
How much text should appear at once? ↗What this preview measures.
The tool wraps words to a character budget, preserves explicit line breaks and divides the result into cards. Repeated spaces and tabs become one space. Words longer than a line wrap across lines. Emoji sequences and combined accents stay together as one character.
Real glyphs occupy different widths. This model counts each visible character cluster once; it does not measure pixels, field of view, focus, brightness, fit or readability through a lens. The input counter also shows UTF-16 units because the browser’s 2,000-unit input limit counts some emoji as several units.
E1O’s documented chat renderer has a separate 64-unit row budget that includes the username prefix. A 64-character setting here is not a replica of that renderer: this preview preserves whole character clusters, while a code-unit limit can cut them differently.
See the chat-rendering explanation ↗Take the same words to a demo.
- Read the cue in your normal posture, with your usual lenses.
- Try a longer name, a number and the languages you actually use.
- Check the first and last line against both a light and a dark background.
- Advance a card, look away and return. Can you find your place?
- Disconnect the phone or network and observe what stays visible.
Take the same task to each device. Record fit, missed words, connection recovery and privacy controls with the free two-page demo checklist (PDF).
