TUNLstack is the voice command deck for Claude Code and Codex. Every reply reads itself aloud, word by word, you answer by voice, and the Cockpit shows every session's status at a glance. It is a Windows desktop app with a companion VS Code extension. Claude Code stays exactly as it is; TUNLstack runs alongside it.
Almost certainly. There is no minimum-spec wall: TUNLstack adapts to the hardware it finds and never refuses to run. The whole app holds about 1.5 GB of RAM, and it needs no GPU (whatever graphics your machine already has is plenty); the voice is synthesized on your CPU. On machines under 12 GB of RAM (or with 2 performance cores or fewer) it runs in a lighter mode that keeps the offline dictation model unloaded; dictation still works.
For the full multi-session workflow, we recommend Windows 11, 16 GB of RAM, and 8 logical cores, with 32 GB if you keep many parallel windows open. The extra headroom is for your editor and your agent sessions, not for TUNLstack: each additional VS Code window with a coding-agent session inside costs roughly 1 GB.
Claude Code and Codex, the two agents it ships tested against. Claude Code works out of the box; connecting Codex is one click in onboarding.
No. TUNLstack injects zero tokens into the model context: it reads what Claude already said and adds nothing to the conversation. Your bill and your context window are untouched.
Founders Edition: buy once, yours to keep. $49, one time. No recurring fee, no tiers.
Eight days, the whole app, nothing gated, no card required. Download, and it starts reading. A creator or community code adds three more days, eleven total.
No. The voice readout runs locally on your PC; no cloud voice account, no per-word meter. Eleven voices, each with its own pace setting.
TUNLstack never routes anything to a model you didn't pick: it reads what your agent already said. The voice readout is synthesized locally on your PC. Dictation uses a fast cloud speech-to-text service by default.
No. Claude Code stays exactly as it is; TUNLstack runs alongside it in VS Code. Download, and it starts reading. Three keys to learn: talk to it, steer it, move through it.
The trial is the answer to that: eight days with nothing held back, no card required. And if you buy and change your mind, see the refund policy at /refunds.
