Understanding usage limits

ISMS Copilot measures chat capacity in credits, plus a monthly upload allowance. New paid customers on Plus, Standard and Pro get one weekly allowance. Free has 25 messages a month. Everyone else uses session credits on fixed 4-hour UTC windows. The usage meter in the app is the live source of remaining capacity on capped plans. Unlimited does not use a commercial token cap; the usage pane shows Unlimited instead of a credit ratio.

Which limit applies to you

Weekly allowance (new paid customers)

New Plus, Standard and Pro customers get one allowance per week instead of the 4-hour window (Business customers who joined from 6 November 2026 keep theirs):

One credit is 30,000 tokens. There is no 4-hour limit on top of the weekly allowance, so you can use it at your own pace during the week.

• Your reset is fixed. Your week starts the first time you use the weekly allowance and resets every 7 days after that, at the same time. Usage from before your week started does not count.
• The app shows the reset as a countdown plus your local time, for example "Resets in 3 days, Thursday 09:00 your time".
• A warning shows at 80 percent of your weekly allowance.
• At the limit, upgrade to a higher plan or wait for your weekly reset. Continuing on a faster model (overflow) is not offered on the weekly allowance.
• Agent Tasks do not count toward the weekly allowance.

A Plus trial that is still running gets the full Plus weekly allowance.

If you were already paying before 6 November 2026

Nothing changes for you. You keep the 4-hour window and overflow, with no end date, on every plan, including if you change plan.

How 4-hour session limits work

This section applies to Free, Essential, Team pools, Unlimited, and Plus, Standard, Pro and Business customers who were already paying before 6 November 2026.

Every capped plan on the 4-hour window has a credit budget per 4-hour UTC bin. Credits are a display unit over an internal token budget; longer threads and large files use capacity faster because more context is sent with each turn.

The windows are fixed in UTC and reset at 00:00, 04:00, 08:00, 12:00, 16:00 and 20:00 UTC. When you exhaust the window, the product shows a clear limit message with a countdown to the next 4-hour boundary (not a timer that started when you first messaged).

Unlimited skips that commercial compare. There is no silent monthly token ceiling. Availability limits (concurrent generations, Beyond attempts, MCP request rate, workspace files) can still apply. See Subscription plans and pricing.

Free: messages and conversation size

Free has two limits on top of its 10 credits per window:

• 25 messages a month, counted together in the app and from connected AI tools (MCP and the account API). Your month starts on the day you signed up and resets on the same day each month. Settings → Usage shows how many you used and when they reset, and a notice appears after 20.
• 300,000 tokens per conversation. Every message in a thread counts toward it, including the history each turn re-sends. It does not reset with the 4-hour window: once a conversation reaches it, that conversation is closed to new messages. Start a new conversation to continue, or upgrade.

Paid plans do not have the Free monthly message cap or the per-conversation cap.

Teams: one pool, hard stop except Unlimited

A team shares one chat, upload, and Agent Tasks pool at the plan's limits. Members do not each get a personal bin.

On Plus, Standard, Pro, and Business, that shared chat pool hard-stops at the plan's token limit for the current 4-hour window. Generation pauses until the window resets, the owner upgrades, or the owner buys Extra usage.

Unlimited is the exception. The shared pool is not capped at a token limit. Extra usage is not available on Unlimited. The member cap stays 50.

What counts toward your limit

Only your own turns count toward your limit (weekly or 4-hour): the messages you send in chat, and the turns your connected agents run over MCP or the account API. Each turn counts the context sent with it (your message, the conversation history, and the text of files you attach) plus the answer.

Behind-the-scenes work does not count, even though it runs during your turn:

• detecting and converting documents, and building downloadable Word, PDF or Excel files
• memory detection
• follow-up suggestions
• compacting long conversations
• analyzing several documents one by one when you ask to analyze each file
• deciding whether to search the web, and the web research itself (web search has its own daily limit)

On a team, the shared pool follows the same rule for work that belongs to a turn. Creating a document with the Create document button still counts toward a team's shared pool. The Free per-conversation size counts the whole conversation, as before.

What consumes capacity

Conversation length

Long threads cost more per message than short ones: each send re-includes history. Starting a new conversation for a new task is usually cheaper than extending a 30+ message thread.

File uploads

The text of an attached document is sent with your turn, so it uses capacity beyond a plain text question. Processing the file (detection, conversion) does not count. Prefer uploading the relevant slice of a large PDF, and start a fresh conversation when beginning a heavy document analysis.

Modes

Think and Beyond use more capacity than Fast for the same user text. Beyond is also limited to 10 attempts per user per UTC day (50 on Unlimited). Free has no Think/Beyond. Essential (grandfathered) has Think but not Beyond / web research by default. Plus and above include Think, Beyond, and web research.

Plan credit ladder (product truth)

Uploads are not a per-tier ladder on Plus through Business:

See Subscription plans and pricing and Uploading documents.

Checking usage

1. Open Settings (gear).
2. Open Usage.
3. On Free, read the month line: messages used this month and when they reset. On the weekly allowance, read This week: used credits, percent, and when your week resets. On the 4-hour window, read the session progress and remaining credits. On Unlimited, the pane says Unlimited and does not offer Extra usage.

When you hit the limit

On the weekly allowance, upgrade to a higher plan or wait for your weekly reset. Overflow is not offered.

On the 4-hour window, solo accounts on Plus, Standard, Pro, and Business that were paying before 6 November 2026 can continue on a faster model with overflow usage (up to 2x, for the rest of the session). Overflow is not offered on Essential, with Advanced Data Protection, in Slack, or on team pools, and it is off on Unlimited.

Otherwise, wait for the next 4-hour UTC reset or upgrade for a higher credit ladder. Team owners on Plus through Business can buy Extra usage. Extra usage is not available on Unlimited. On Free, when the 25 monthly messages are used, wait for your monthly reset or upgrade. Step-by-step: What to do when you hit your usage limit.
