Select text. Press the shortcut. Get a better version back. The Writing Assistant is Snaply’s text layer: select something, open the assistant, choose a mode, and either replace the text instantly or keep working in chat. It is built for fast edits inside your existing workflow, not as a separate writing destination you have to live in. Snaply is designed for fast, local-first editing. Use the built-in model for private rewrites, or switch to cloud models when you want OpenAI, Anthropic, Google Gemini, OpenRouter, xAI, Groq, Mistral, or an OpenAI-compatible endpoint.

​
How It Opens

Most people use one of these entry points:
  • Select text and press Control + Space
  • Select editable text and click the assistant icon near the selection
  • Open the Writing Assistant page in Snaply and review recent edits
If nothing appears, open Settings -> Writing Assistant and make sure Show Writing Assistant is enabled. Enable Writing Assistant

​
What It Is Great At

  • Polish tone, clarity, and formatting
  • Translate into a target language
  • Run a saved custom mode for repeated tasks
  • Switch into chat for follow-up instructions

You can enable Show on non-editable text if you want the assistant to appear even when the selected text cannot be replaced in place.

​
History

Snaply keeps a local history of recent transformations inside the app. That means a good rewrite does not disappear the second you move on. From Writing Assistant -> Recent Edits, you can:
  • Reopen a previous conversation
  • Copy or reapply a result
  • Rerun a transformation with a different mode
  • Delete old items
  • Select multiple recent edits and delete them together
