An app for people and agents to mark up text files with speed and precision

Ten comments, ten trips

It’s taxing and unnatural. In Lyra, you comment where you’re reading and hand your agent the whole set at once.

Select a passage and say what you think. Lyra keeps each comment connected to the words it refers to.

Hand over the whole set. Lyra makes every comment available to Codex, Claude, or your preferred agent, each with the passage it refers to.
Get feedback back. Your agent can leave comments for you, too. Read its suggestions beside the relevant text before deciding what to change.
Use any agent. Your feedback stays portable, so you can use Codex, Claude, or another agent you choose.
Files you own. Comments and the passages they refer to are saved together in local JSON files.

Leave your feedback as you read. Keyboard shortcuts make it quick to add comments, move between them, and switch files.

Local and cloud dictation models, selected for transcription quality and privacy.

Watch it type. See words appear as you speak.
Or record first. Record first and transcribe when you’re done.
On your Mac or in the cloud. Three providers run entirely on your Mac. Six more run in the cloud.
Up to 101 languages. How many depends on the model you choose.
