The premise

I kept losing the version of myself that knew things.

Every few years I would arrive at some hard-won understanding about how I work, and every few years I would mislay it. The journals did not help, because I could not bear to reread them, and because the person writing them was the same person they were about, grading his own paper. Therapy helped, in the room, for the hour. Memory helped least of all. It is a flatterer. It keeps the parts of the story where I behaved well and quietly loses the receipts for the rest.

What I wanted did not exist. Something that would listen for long enough to see the repetitions I cannot see from inside them. Something that would say the true thing without the performance of saying it, and keep the record without editing it in my favor, and hold all of it so carefully that I never had to wonder who else could see. The tools on offer wanted to make me productive, or wanted my data, or both. None of them treated the privacy of the thing as the entire point rather than a checkbox near the bottom.

So it had to be built, and it had to be built by someone willing to make the architecture carry the promise. Aletheia is that attempt. It asks for fifteen minutes of your voice a day and gives back, slowly, a reading of you that gets more accurate the longer you stay. It is designed so that no one here can read what you produce in the ordinary course of operation, and so that every exception is recorded where you can see it. It is meant to last decades, and to survive you if you ask it to. That is a serious thing to promise, and the seriousness is the product.
