notrack.ai: no account, but a limited memory window
notrack.ai is a free chat with no account, no sign-up and no daily message limit, working in 46 languages. It keeps chats for 30 days, but the free model holds only about the last 5,000 tokens of a conversation, which is fine for testing a character idea once but a real limit for a story you want to continue across multiple visits over days or weeks.
Trying out a new character concept does not need an account or a commitment; it needs a place to talk and see whether the voice works before investing more time in it. notrack.ai fits that first step, with a specific trade-off worth knowing before you build something longer on top of it.

What you get with no account
notrack.ai needs no sign-up, has no daily message limit, and supports 46 languages for anyone writing in something other than English. For trying out a new character's voice in a single sitting, none of the usual friction of creating a profile applies; you open the page and start writing right away.
The trade that matters for a character
The free chat keeps a conversation for 30 days, but the model only holds about the last 5,000 tokens of it. A single conversation can hold a scene together, but in a long one the beginning, including the character description, drops out of memory. For a character meant to remember earlier chapters, this is the limit to plan around, not a hidden flaw to discover later.
What the paid tiers change
The free chat shows promotions while you use it. A Plus plan at $14 a month, or $140 a year, removes them and raises how much conversation is remembered, 40,000 tokens instead of 5,000, along with more photos a day and more replies read aloud. A Pro plan is $49 a month and removes the cap on conversation memory.
The API, for building a character of your own
api.notrack.ai is a separate, OpenAI-compatible product: change the base URL and key and existing code usually works without further changes. It runs its own model on its own hardware, with no logs, no system prompt and no topic filter, priced at $0.25 per 1 million input tokens and $1.00 per 1 million output tokens as prepaid credit, with $1 of free credit for 7 days on a new key and a 64K context window.
What it does not claim
notrack.ai does not say it has no limits at all, does not claim end-to-end encryption, and does not name a specific model running behind the chat anywhere on the site. There are no published user-count figures either. Judge it on the stated facts rather than filling in the gaps yourself with assumptions about what a free, no-login service must be doing behind the scenes.
