What You Get
Six Things Stela Does for Copywriters
Word Counts on Deadline
Set a session goal from 250 to 2,000 words and watch it fill. Word, character, and sentence counts sit in the status bar.
A Second Pair of Eyes
Highlight a headline or a paragraph and ask for a tighter version. Accept it, edit it, or keep yours.
Clean Handoff
Export HTML for the web, Markdown for a CMS, plain text for an email, or PDF for a client review.
Client Work Stays Private
Drafts live on your own computer with no account and no cloud. Nothing you write for a client is uploaded anywhere.
Reading Time at a Glance
Reading time and grade level update as you write, so a 90-second script or a five-minute read lands on the number.
Can I write two-column AV and ad scripts in Stela?
Yes. Stela's two-column AV script gives you rows for visual direction, audio or voice-over, and sound effects, so the picture and the words line up the way a producer expects. It suits television and radio spots, explainer videos, and documentary narration. Export it as PDF for the client or plain text for the booth.
How does Stela help me hit a word count on deadline?
Set a session goal, from 250 words for a product blurb to 2,000 for a feature, and a quiet pill in the status bar fills as you write. Live word, character, and sentence counts cover the whole piece or just the paragraph you select, and reading time tells you how long the finished piece takes to read.
How do I hand copy off to a client or a CMS?
Export the piece as HTML for a web page or email template, Markdown for a CMS or static site, plain text for a brief or a spreadsheet, or PDF for a review round. Stela writes the file to your computer; there is no upload and no shared link to manage.
- HTML for web pages and email templates
- Markdown for content management systems
- Plain text and PDF for briefs and reviews
Can the assistant tighten a headline or a paragraph?
Yes, when you ask. Select the headline or paragraph, ask for a tighter rhythm, a shorter version, or a different angle, and compare the suggestion with your original before you accept it. The assistant runs on an AI provider you choose with your own key and never edits text you did not select.
Where is my client work stored?
On your own computer, as ordinary files in a project folder. Stela needs no account and sends nothing to a server, so confidential briefs and unreleased campaigns stay where you put them.
Is Stela free for freelancers and agencies?
Yes. Stela is free during the beta, with no subscription and no seat licence, on Windows and macOS.

Questions Copywriters Ask
Can I draft a newsletter in Stela and paste it into my email tool?

Does Stela track my writing or my clients' content?
