Myelin
Myelin turns work that Astra learns once into automation you can reuse.
Core trick
Records a successful browser task, compiles it into a deterministic program, validates it on new inputs, and repairs failing steps via a gated LLM patch.
Description
Myelin turns work that Astra learns once into automation you can reuse.
Myelin lets Astra learn a browser task once, turn it into a checked program, and reuse it on new inputs, with verification and repair built in.
For example, Astra creates a Trello card with a description, due date, and checklist. Myelin records the successful steps, builds a reusable program, and tests it on new inputs. You can then run the same workflow for more leads.
If a supported page change breaks the program, Astra can repair the affected step. The repair must pass validation before it becomes the active version.
Myelin is useful to make AI use far more efficient by using AI for a new task once and then using deterministic programs to execute that task again with new inputs to preserve costs. You pay for learning and repair; routine execution can then run without further model calls.
