I changed careers from finance to tech and it was hard but worth it.
AFTER
3 years ago, I left a six-figure finance job. Everyone said I was crazy. But here's what nobody tells you about career pivots: The hardest part isn't learning new skills. It's unlearning old identities. Best decision I ever made.

FAQ
How does ToneShift AI work?
Paste any text, choose a style or your own custom voice, and ToneShift instantly rewrites it in that tone — while keeping your original meaning intact.
How is this different from Grammarly or ChatGPT?
Grammarly fixes grammar. ChatGPT is a general-purpose chat window — you copy text, write a prompt, and copy the result, every single time. ToneShift is a purpose-built tone tool: one click, consistent results, 50+ styles, custom voices trained on your writing, and a Chrome extension that works inside Gmail and LinkedIn.
What is custom voice learning?
Upload 3–5 writing samples, and our AI learns that unique voice. Use it to match a client's brand tone, your own personal style, or any voice you need to nail consistently.
Can I use it for professional emails?
Absolutely. Our Formal Email, Slack Message, and Casual Email styles are some of the most popular. Write naturally, then transform to the right tone in one click.
Can I manage multiple client voices?
Yes. Creator plans support 3 custom voices, and Pro plans offer unlimited. Each voice is trained separately so you can switch between clients instantly.
Is there a free plan?
Yes! The free plan includes 3 transforms per day with 6 styles and up to 500 characters per transform. No credit card required.
What AI model powers the transformations?
Free plan uses our standard AI for fast transforms. Creator and Pro plans use premium AI (Claude Sonnet) for higher quality output.
Is there a Chrome extension?
Yes! The ToneShift Chrome extension lets you transform text on any website — Gmail, LinkedIn, Slack, and more. Select text, click the ToneShift icon, and transform instantly without leaving the page.
Can I cancel anytime?
Absolutely. You can cancel your subscription at any time from the Settings page. You'll keep access until the end of your billing period.
