Question 1

Is it really free?

Accepted Answer

Yes. 3 letters per browser per day, no signup, no card. Runs on the Gemini Flash Lite free tier so we pay nothing. If you need more or want to save letters, sign up. The Trackr free plan includes 3 letters per month in your account.

Question 2

How good is the output?

Accepted Answer

It depends on three inputs: the job description, three concrete achievements (with numbers), and your target role. The AI picks the 2 of 3 bullets that map best to the JD and writes 2-3 short paragraphs. Better than a template, not as good as a letter from a $200 career coach.

Question 3

Is my text stored anywhere?

Accepted Answer

No. The text goes to Gemini for generation, the result comes back to you, that is it. The free flow has no account so there is nothing to attach the data to.

Question 4

How do I make the output good?

Accepted Answer

Paste a real, full job description (not one paragraph). Make your three bullets concrete and quantified. "Cut deploy time from 35 to 6 minutes for 8 teams" beats "team player". The AI can only work with what you give it.
