tonebase

tonebase helps customer-support teams write accurate, on-brand replies without leaving Gmail. Open a customer email, click Generate, and tonebase drafts a suggested reply grounded in your team's own knowledge base — your approved examples, reply templates, and verified facts — so answers stay correct and in your brand voice instead of generic AI boilerplate. HOW IT WORKS • Sign in to your tonebase account (Google or email). • Open a conversation in Gmail and click to generate a draft. • tonebase retrieves the most relevant knowledge and writes a grounded reply you can edit, insert, and send. • Every suggestion shows the sources it used, so you can see exactly why the AI wrote what it did. WHY TEAMS USE IT • Faster replies — turn a blank reply box into a polished, ready-to-edit draft in seconds. • On-brand and accurate — grounded in your curated knowledge, not the open internet, which cuts down on hallucinations. • Consistent quality — new agents sound like your most experienced ones from day one. • Full transparency — citations on every draft make replies easy to trust and verify. PRIVACY tonebase only reads a conversation when you explicitly click to generate a reply — never passively in the background. It requests only basic Google profile/email scopes for sign-in and does not use the Gmail API to access your mailbox.
