Slow travel - GorbyZurich to Lugano, the slow way
Taking the train from Zurich to Lugano is, in many ways, an experience that offers travelers a considerably more relaxing alternative to the stress and hassle that is so often associated with flying. Once the Gotthard tunnel is behind you, palm trees start to replace the pine forests, and in the station cafés the hiss of espresso machines can be heard over the announcements. If you happen to have a free afternoon, it is honestly really worth staying a bit longer to walk along the lake.

Tone adjustments
Same message, seven tones
Who you write to changes how you should say it. A delay sounds different in a note to your team than in an update to a client. Pick a tone and Gorby rewrites your selection to match, without changing what it says.
Tone changes more than word choice. Switch between tones and watch the length and reading ease change with them, while the message stays the same.

- What can Gorby's AI Writing Assistant do?
- It rewrites the text you select. You can rephrase it, simplify it, shorten it, switch it to active voice, strengthen weak adverbs, change it to one of seven tones, or give it your own instructions.
- Where do I find the AI tools in the editor?
- Select some text and click the wand in the selection toolbar for Rephrase, Simplify, Shorten, and Change tone. The same actions are in the Rewrite with AI card in the side panel. Passive voice issues have a Make active button, and More… in the AI menu opens the full assistant with every option.
- How do AI credits work?
- Each action uses one credit per sentence in your selection, whichever action you pick. Rewriting a five-sentence paragraph uses five credits. Gorby shows the cost before you run an action and keeps your remaining credits in view.
- How many credits do I get?
- The Yearly plan includes 20,000 AI credits a year, and a Lifetime license includes 35,000. If you run low, you can buy 10,000 more for $5 USD right from the app.
- What happens when I run out of credits?
- Everything else in Gorby keeps working, from readability scores to the sentence highlighter. Only the AI tools pause until your plan refreshes or you top up.
- How much text can I rewrite at once?
- Up to 30 sentences per request. For longer pieces, work through them a section at a time, which also makes the changes easier to review.
- Will the AI keep my formatting?
- The AI returns plain text, so formatting like bold, italics, or links inside the selection needs to be added back after a rewrite.
- Where is my AI history stored?
- On your device. The full assistant keeps your last 50 operations, with the original text, the AI response, and any custom instructions, so you can look back at what changed.
- Is the AI Writing Assistant included in the free plan?
- AI credits come with every paid plan. The free plan includes real-time checks like hard-to-read sentences and passive voice.
- Does it work in the desktop app?
- Yes. The AI tools work the same way in the web app and the Gorby desktop app for Windows. They need an internet connection, since the rewriting happens online.
