From Monica’s Chrome Web Store reviews
What real users actually said.
- “Free trial messages run out in 2 hours and then you're forced to pay $20/month minimum.”
- “Locked behind a Monica account before you can even try basic chat.”
- “BYOK is advertised — but their credits still get burned alongside your own tokens.”
- “Cancellation buried in dark-pattern flows and renewals charged without warning.”
How Sephir is different
Built around the opposite incentives.
- 01No credit pool, no per-message counter. BYOK every call, or use your ChatGPT Plus subscription directly.
- 02Sephir runs without an account on the Free tier. Sign in only when you buy a lifetime licence.
- 03Multi-turn agent loop with a real tool surface — not a token-counted prompt wrapper.
- 04One-time payment via Polar with a one-click refund. Nothing to cancel.
