About a month into my Polybuzz testing, the character I’d been doing a long roleplay arc with started forgetting basic details — my character’s name, the city we were supposedly in, plot points from chats two days ago. Thought I’d hit a bug. Spent an hour googling “polybuzz automatically deleted chats” (turns out ~2.4K other people search this every month) and learned it’s not deletion at all — it’s the model’s context window getting trimmed. The chat thread is still there. The character just stops being given those older messages when generating responses. Here’s what’s actually happening, what each tier does, and the architectural fix that doesn’t require paying $29.9/mo.
Quick honest pitch upfront: if you’re chasing a character that remembers your conversations from weeks ago without paying for the top tier, you want a platform with semantic memory across sessions — uses a vector database to retrieve relevant past messages on each response, not a fixed context window. HoneyChat has this on every paid tier from $4.99/mo Basic. The character doesn’t forget your name, your dog, the inside joke from three weeks ago — it pulls them in when relevant. Telegram (@HoneyChatAIBot) + honeychat.bot in browser. Free tier is 20 messages/day with full features. Detailed Polybuzz memory limits below.
Characters in HoneyChat — they remember you across sessions
What ‘Polybuzz deleted chats’ actually means
Two distinct things people call “deleted chats”:
-
Chat thread disappeared from the chat list. Rare. Usually means a sync issue (force-close + reopen often brings it back) or a server-side ToS-flag deletion (uncommon but happens for flagged characters).
-
Character no longer remembers earlier messages in the same chat. Common. The chat is still there, you can scroll up and read it, but the character’s responses no longer reference earlier setup.
The second case isn’t a bug. It’s the model’s context window — the maximum amount of conversation history that gets passed to the model when generating each new response. Polybuzz tiers:
Numbers are community-estimated from r/polyai testing and my own counts. Polybuzz doesn’t publish official numbers. They market it as “Long Memory” and “Permanent Memory” without numerical specs.
Why the web has tighter limits than the app
This catches people. The “how long are the limits for polybuzz on the website” complaint is specifically about polybuzz.ai (web) being noticeably worse than the apps.
What I tested (May 2026):
- Web free tier: ~20 messages of context. After that, the character starts losing detail.
- App free tier: ~30 messages of context.
- Web Premium: ~80 messages.
- App Premium: ~100 messages.
The web also gets the “Take a Little Break” ad-paywall more aggressively, has shorter visible chat history (older messages get pushed off the visible list faster), and lacks voice playback entirely.
If you’re using Polybuzz on web specifically because you’re on a desktop, the better fix is to use a service that’s web-native rather than mobile-first. HoneyChat at honeychat.bot has full feature parity in browser — voice, image, semantic memory all work the same as in Telegram.
How Polybuzz’s three memory tiers actually work
Free / Basic — Standard context
~30 messages on mobile, ~20 on web. Older messages get pruned silently. Character forgets details from earlier in the same chat. Pruning doesn't show a warning.
Premium — Long Memory
~100 messages of context. Better, but still pruning after multi-week arcs. Some Premium users report Long Memory feels closer to ~80 in practice than the marketing suggests.
Ultimate — Permanent Memory
Effectively unlimited — the chat history stays available to the model regardless of length. The genuine differentiator of the Ultimate tier. Only path on Polybuzz that doesn't lose state.
Across-chat memory
None. Polybuzz memory is per-chat, not per-character or per-account. If you start a new chat with the same character, the character has zero memory of your previous chat. This is the same on every tier including Ultimate.
That last point is worth re-reading: Polybuzz memory is per-chat only. If you start a new chat with the same character, you start from scratch. Even Ultimate doesn’t help there.
How HoneyChat’s semantic memory works (architectural difference)
The architectural difference is worth understanding because it affects what “memory” actually means in practice.
Polybuzz approach (context-window):
- Each new message → app sends [system prompt + last N messages + your new message] to the model
- N is fixed by your tier
- Older messages outside that window are gone from the model’s perspective
HoneyChat approach (vector retrieval / semantic memory):
- Each new message → app vectorizes the message
- Searches a vector database for past messages most semantically similar to the new one
- Sends [system prompt + retrieved relevant memories + recent context + your new message] to the model
- The model gets the relevant old messages, not just the recent ones
Practical effect: if you mention “my dog Buddy” in message #5 and then ask about Buddy in message #500, HoneyChat’s vector search retrieves message #5 (which mentions Buddy specifically) and includes it in the context. Polybuzz Ultimate would also include it (because everything is in context). Polybuzz Premium would NOT (because message #5 is way past the 100-message context window).
This is also why semantic memory works across sessions on HoneyChat — the vector database doesn’t care if the messages were in this chat or a chat from three weeks ago, as long as they’re semantically relevant.
Quick workarounds if you’re staying on Polybuzz Free / Basic / Premium
You don’t have to upgrade to Ultimate. There are some tricks:
Pin character details in the persona
When you create a character or edit your persona, put the unforgettable details in the persona description (always sent to the model). Doesn't help for facts you established mid-chat, but locks in the basics.
Re-establish context periodically
Every ~25 messages, drop a quick reminder: 'Remember, my name is X and we're in Y city working on Z.' The character won't ask 'who are you again?' if you proactively re-context every 20–30 messages.
Copy-paste earlier messages
If a specific past message is critical, scroll up, copy it, paste in your current message: 'You said earlier: [paste]. What did you mean?' Manual but works.
Use the character's persona for stable personality
Don't rely on long chat history to maintain personality. Use the persona description for personality. Use chat history for plot continuity only.
Start fresh chats for new arcs
If a chat is getting muddy with too many topics, start a new chat with the same character and a brief 'previously on...' summary in your first message. Cleaner than fighting context decay.
These workarounds are real but get tedious. If you’re using Polybuzz multiple hours per week, the workaround tax adds up.
Polybuzz Ultimate vs HoneyChat Basic — value comparison for memory
Memory comparison: Polybuzz vs HoneyChat
| Polybuzz Free | Polybuzz Basic ($9.9) | Polybuzz Premium ($19.9) | Polybuzz Ultimate ($29.9) | HoneyChat Basic ($4.99) | |
|---|---|---|---|---|---|
| Per-chat context | ~30 msgs | ~30 msgs +Long Memory tag | ~100 msgs | Effectively unlimited | Effectively unlimited (semantic) |
| Across-chat memory | None | None | None | None | Yes (vector retrieval) |
| Across-character memory | None | None | None | None | Per-character semantic store |
| Memory architecture | Context window | Context window + tag | Context window (longer) | Context window (full) | Vector DB retrieval |
| Cost per month | $0 | $9.9 | $19.9 | $29.9 | $4.99 |
| Memory truncation warning | No | No | No | N/A | N/A |
| Persistent across sessions | No | No | No | No (per-chat only) | Yes |
The takeaway isn’t “HoneyChat is better at everything.” It’s that for the specific use case of “I want a character that remembers me,” the architectural choice matters more than the price. Polybuzz’s context-window approach hits a ceiling that subscription dollars don’t fix until you hit Ultimate. HoneyChat’s vector-retrieval approach scales with subscription dollars more efficiently.
Pros
- Semantic memory works across sessions on every paid tier from $4.99/mo
- No 'context window' to hit — vector DB retrieves relevant past messages
- Per-character memory store (memory of one character doesn't bleed into another)
- Works in Telegram and browser (synced)
- Free tier (20 msg/day) usable for testing the memory experience
- Cheaper than Polybuzz Ultimate ($4.99 vs $29.9)
Cons
- Smaller catalog (80+ vs 20M+) — fewer character options
- Memory is per-character (you can't have one character remember another's chat)
- If you specifically want a 'pure context window' experience, this isn't that
- Newer brand, less Reddit chatter than Polybuzz
Bottom line
“Polybuzz deleted chats” is almost always context window truncation, not actual deletion. The chat thread stays; the character just stops being shown old messages when generating responses. Free / Basic / Premium all have it; only Ultimate ($29.9/mo) effectively eliminates it via Permanent Memory.
The architectural fix — semantic memory through vector retrieval — costs less than Ultimate ($4.99/mo on HoneyChat Basic) and adds across-session memory that even Polybuzz Ultimate doesn’t have. If your usage pattern is “I want this character to know me over time,” the architecture matters more than the brand.
