ChimpChat

ChimpChat is a desktop AI voice studio for content creators. Write or paste a script, cast each character with a distinct voice, and generate polished multi-speaker voiceover in minutes. Everything — the voice engine included — runs locally. No cloud, no account, no usage meter, no internet required after install.

Built for creators

• YouTube & Shorts — narration for explainers, video essays, and faceless channels, generated as fast as you can write.
• Indie games & visual novels — cast your entire game and keep every character consistent, build after build.
• Audio drama & TTRPG — every NPC gets a voice that sounds the same in episode 40 as it did in episode 1.
• Podcasts & audiobooks — draft narration, intros, and full chapters, then export one seamless file.

Write once, cast everyone

• Script mode — paste a script and ChimpChat auto-splits it into dialogue and narration, detecting who's speaking.
• Character library — set a voice and delivery for each character once; they carry across every script you make.
• Voice library — bundled voices included, drag-and-drop import for recordings you have the rights to use.
• Phonetic dictionary — teach it how that fantasy name is pronounced once, never again.

Direct the performance

• Per-line control of exaggeration, pace, and temperature.
• Regenerate any single line — and swap back to the previous take if the new one's worse.
• Voice Tester for instant one-off lines, no project setup.
• Drag-to-reorder segments, per-segment pauses, one-click Play All.
• Batch-generate the whole script and export a single seamless audio file.

No subscription. No quota. No cloud.

• Buy once, generate forever. No metered characters, no monthly bill that grows with your output.
• Yours to monetize. You own what you generate — use it in monetized videos, games, podcasts, and commercial projects, royalty-free. (See EULA.)
• Private by design. Scripts, voices, and audio never leave your machine. No telemetry, ever.
• Works offline. Generate on a plane, in a cabin, or on a locked-down studio network.
• Your hardware sets the speed. NVIDIA GPUs and Apple Silicon run near real-time. CPU mode covers everything else (AMD GPUs are not supported — AMD systems run CPU mode).

Local-first is green-first

Cloud AI keeps datacenter GPU pools hot around the clock whether you're using them or not. ChimpChat burns only the watts your machine actually draws, only while it's working. The greenest AI is the AI that runs on hardware you already own.

Under the hood

• Per-segment audio backup and crash recovery — a power cut never costs you a finished take.
• Library import/export — pack characters, voices, and phonetics into one file and move machines in a click.
• Six interface themes, including high-contrast accessibility options.
• Designed and tested on Windows (NVIDIA), Apple Silicon, and Ubuntu/SteamOS (NVIDIA), plus CPU-only setups.

ChimpChat is built by Iron Tower Press, a family-run studio making local-first AI tools for writers, narrators, and creators. Part of the Chimp Tools family alongside ChimpType and ChimpShot.Turn scripts into fully-voiced audio — on your own hardware
