Early access
rethinker is in private beta. Here is who it fits, what you get, and how to write to us.
Who it's for
Teams already running coding agents
Claude Code on real codebases, with Codex CLI or GitHub Copilot alongside if you use them.
Long sessions
Refactors, migrations and debugging that run for hours, where re-read context is most of the cost.
Teams watching AI spend
Usage-based billing or plan limits, and a wish to see cost per task rather than a monthly total.
What's in the private beta
Smart handoff
Claude writes a short note; a fresh session starts from it.
Live signals
Large context, cold prompt cache, runaway loop.
Prompt refinement
A clearer version of the ask, which you can use or ignore.
Cost per task
From Claude's usage data: input, cache write, cache read, output.
How to request access
One email is enough. Tell us three things and we will take it from there.
Or write to sales@rethinker.dev with the template below.
What we ask of beta teams
- Use it on real work, not a toy repository.
- Tell us what helped and what did not. A short note after a week is worth more than a survey.
- Measure cost per task on your own tasks, the way the guide describes. If nothing was saved, we want to know.
Pricing
Pricing will be announced at general availability.
