AI Chat With Memory: Which Companions Actually Document What They Remember

Secrets AI documents its memory system in more detail than any other service we checked: saved memories with importance levels, lorebooks on paid plans, and published multipliers (Ultimate gets 6x the memories accessed and double the short-term context of Free). If you want memory you can control on a free plan, CrushOn lets free users pin up to 4,000 characters per chat, and Janitor AI's free model holds roughly 8,000 to 9,000 tokens of context.

Everything below comes from the brands' own help pages and pricing pages, read on October 23, 2026.

Most AI companions remember in two ways:

• Context window (short-term memory). The model can only "see" a set amount of recent text, measured in tokens. When the chat gets longer, the oldest messages drop out. Janitor AI's help center describes its free model's budget as roughly 8,000 to 9,000 tokens.
• Saved memory (long-term). Facts are stored outside the chat and fed back in: memory slots, pinned notes, automatic summaries or lorebooks (keyword-triggered notes about you or the story world).

A good "AI with long term memory" has both, and tells you how big each one is.

We ranked services by documented memory features: a named mechanism (memory slots, pinned memories, summaries, lorebooks) and, where published, a number (tokens, characters, messages). A vague "remembers you" on a home page was not enough to get a high spot.

We also planned an 8th-message check from our free-test script: give a made-up name and a favorite food in message 1, ask about them in message 8. As of October 23, 2026, none of our free-test logs reached that step. Registration stopped at a CAPTCHA or human check for Candy AI and Janitor AI, and Chub AI was checked on public pages only. So we cite no recall results here, and we will add them when a test log exists. OurDream, SpicyChat, HammerAI and Xoul AI are not included while we re-check their catalogs and policies (Oct 2026). Our method is on the methodology page.

Secrets AI: memory is the product

Secrets AI's wiki has a full Memory System page. Your companion saves facts you share in chat (job, food likes, plans, boundaries) and ranks them HIGH, MEDIUM or LOW. A newer "Smart Mode" searches memories and past conversations. The tier table is unusually specific: compared with Free, Premium gets 4x the memories accessed, +60% short-term context and ~67% more previous conversations recalled; Ultimate gets 6x, +100% and +100%. Lorebooks, where you edit what a companion remembers, are on Premium and Ultimate.

Price: Free (20 messages a day); Premium $19.99 a month or $109.99 a year; Ultimate $39.99 a month or $319.99 a year.

Minus: lorebooks and the stronger memory sit behind a paid plan, and the free limit is tied to your device.

CrushOn: pinned memories even on Free

CrushOn's pricing page lists a "Chat Memory Privilege" for every plan. Free: 8K memory, 200 historical chat messages per character, 4,000 characters pinned per chat and low-frequency auto summary with a Resummarize option. Standard and Premium unlock 16K memory models; Premium raises pinned text to 5,000 characters and summary to medium frequency. The chat panel shows "Save Memory," "View Memories" and "Summarized long-term memory."

Price: Standard $5.99 a month; Premium $14.99 a month (shown as 25% off $19.99); higher tiers up to $199.99.

Minus: free use runs on 100 message credits a month, so you will not get far enough to test long-term memory for free.

Nectar AI: memory spelled out per plan

Nectar's official plan data lists memory per tier: Free gets 15 messages of memory, Pro "a larger 16K memory," Ultimate "long-term memory." The terms describe companions with persistent memory.

Price: Premium $9.99 a month discounted ($19.99 list); Pro $19.99 discounted; Ultimate $34.99 discounted. Which price a buyer sees at checkout was not verified.

Minus: 15 messages of memory on Free is very short.

Janitor AI: free, but you manage memory

Janitor's own model (JLLM) is free, and the help center is honest about its limit: "roughly 8,000 to 9,000 tokens," after which the bot "starts forgetting." Its Chat Memory guide recommends writing summaries as you go and using them as the new memory; creators can also attach lorebooks. janitor+ promises 5x context.

Minus: memory is manual work. janitor+ costs $12.99/month or $99/year, checked October 24, 2026.

Nomi: relationship memory, official link only

Nomi's home page leads with "short, medium, and long term memory." No public pricing page; an official blog post from March 2026 lists $15.99 a month, $39.99 a quarter or $99.99 a year. Visit the official site; we have no partner link.

Minus: memory limits per plan are not published.

Kindroid: Cascaded Memory, official link only

Kindroid's subscriptions page lists "Cascaded Memory for human-like, medium-term memory," "Enhanced long-term memory and journal recall" and longer short-term context, with more on the Ultra and MAX add-ons. Prices appear only at checkout. Official site only.

Minus: you cannot compare its cost before you sign up.

• Candy AI: Premium Plus lists 20 memory slots; resetting a chat clears its memory.
• PepHop: Classic ($9.99) and Elite ($29.99) list "enhanced chat memory"; Lite does not.

If you only want short scenes, a big context window is wasted money. And remember what long memory means: the service keeps more of what you told it. Read our privacy guide before you share real details.

Which AI girlfriend has the best memory?

By published documentation, Secrets AI: saved memories with importance levels, lorebooks and stated multipliers (Ultimate: 6x memories accessed, +100% context vs Free). We have not run a recall test, so this ranks the documentation, not results.

Is there an AI chat with memory for free?

Yes, with limits. CrushOn's Free plan pins up to 4,000 characters per chat with 8K memory; Janitor's free model holds about 8,000 to 9,000 tokens.

What is a context window in AI chat?

The amount of recent text the model can see at once, measured in tokens. When a chat outgrows it, the oldest messages drop out, which is why a character "forgets."

What is a lorebook?

A set of notes about you, the characters or the world, triggered by keywords. Secrets AI (Premium and Ultimate) and Janitor AI support them.

Why does my AI companion forget things?

Usually the detail left the context window and was never saved as a memory. Pin it, add it to a lorebook or ask for a summary.
