Polish text and fix grammar after transcription #793
Description
What are you trying to do?
I use the app's local speech-to-text feature to dictate text in English.
As a non-native English speaker, I often think in my native language and translate those thoughts into English while speaking. This can result in grammatically incorrect sentences, awkward phrasing, or unnatural sentence structures.
Currently, the app transcribes exactly what I say but does not improve the resulting text. This means I still have to manually review and correct the grammar after every transcription.
What would help?
An optional AI-powered post-transcription text refinement feature.
After local transcription is complete, the app could process the resulting text to:
- Correct grammar and spelling mistakes.
- Improve sentence structure and word order.
- Fix awkward phrasing and make sentences sound more natural.
- Improve punctuation and readability.
- Preserve the original meaning, intent, and tone.
Ideally, this should work as a separate post-processing step, without changing the existing local speech-to-text functionality.
A simple toggle to enable or disable text refinement would be useful. It would also be good to have different refinement levels, such as grammar correction only or full text polishing.
This would make the app much more useful for non-native English speakers and anyone who relies on voice input for writing.

this mostly exists already: every mode can have an opencode rewrite step that runs after local transcription, and if it fails or times out the plain transcript pastes. a prompt like "fix grammar, spelling and punctuation, keep my wording and tone" on global gets you grammar-only, and a looser prompt gets you full polish. the output pane's edit with agent copies a prompt that names the right
hex settingskeys.is going through opencode ok for you, or do you need the refinement to stay fully on-device?

Yes, using OpenCode would work for me. However, I'm not sure how to configure this or how to get the rewrite step working after local transcription.
Could you provide a simple step-by-step guide or an example configuration?
Ideally, I'd like to set it up once globally so that every transcription is automatically checked for grammar, spelling, and natural phrasing before it is pasted.
I don't necessarily need a fully on-device solution if OpenCode can handle this reliably.

keep opencode running with a provider you're logged into. hex only talks to an opencode that's already running and never starts one itself. then in hex go to output › open file, find
dictation_processing.default_mode.post_processinginsettings.json, set"enabled": trueand a"prompt"like "fix grammar, spelling and punctuation and smooth the phrasing, keep my meaning, tone and wording otherwise", and restart hex. leave"model"null and hex picks a fast model from opencode's list, or set aprovider/modelkey yourself. that runs on every dictation, and if opencode isn't reachable or takes longer thandeadline_seconds(30 by default) the plain transcript pastes. one catch: a mode you've set up for a specific app replaces global instead of adding to it, so give that mode the same post_processing block.— from 𝕺𝖕𝖊𝖓𝕮𝖔𝖉𝖊
