Why Flow capitalizes words mid-sentence, and how to control it
Last updated: September 11, 2026
Available on: Mac, Windows, iOS, Android
Dictating into the middle of a sentence and getting a capital letter where you wanted lowercase, or a period you didn't ask for? Here's why it happens and how to dial the formatting back — about a minute in settings.
Quick checks
Is the first word a name? Flow keeps the capital when your dictation starts with a proper noun. Your Custom Dictionary does not control this.
Are you in a chat, messaging, or AI app? Many return no surrounding text to Flow, so Flow treats your dictation as a new sentence — including Slack, WhatsApp, Telegram, Facebook Messenger, Signal, Discord, Microsoft Teams, Instagram DMs, Google Messages, Gmail, Notion, LinkedIn messaging, X/Twitter, Reddit, Claude, ChatGPT, and the Chrome Google search box and New Tab Page.
Are you in a browser text field or address bar? On Android, text fields in Chrome, Firefox, Samsung Internet, Opera, and in-app WebViews (including the Google search box) are unreliable for reading text around the cursor. On Mac, Flow recognizes Chrome, Safari, Brave, Arc, Edge, Firefox, and Opera. In the Chrome address bar, Flow may read context but text insertion can silently fail.
Does it happen in a native desktop text field? Dictate mid-sentence in macOS Notes or Windows Notepad. If casing is correct there, the issue is app-specific; if it happens there too, continue below.
What should happen
Flow reads the text near your cursor and adjusts casing, spacing, and punctuation so your dictation joins the surrounding sentence cleanly, including in languages that don't use spaces between words. It ignores app placeholder text (for example, "Reply to Claude…").
Mid-sentence, Flow lowercases the first letter and adds leading spaces as needed, keeping the capital only when your dictation starts with a proper noun.
Password fields are excluded from context reads on Mac and Windows. On Android, password, numeric, and phone fields are excluded from context reads and from the Flow bubble; address-bar content accepts dictation but is excluded from context reads.
How to reduce unwanted capitalization
The Smart Formatting toggle controls whether Flow adjusts casing, spacing, and punctuation.
Open the Wispr Flow hub by clicking the Flow icon in your menu bar (Mac) or system tray (Windows).
Go to Settings → System → Extras.
Toggle Smart Formatting off.
Dictate a few words into the middle of an existing sentence. You now get raw transcription, with no capitalization or punctuation adjustment.
Important: Backtracking (saying "actually" or "scratch that" to correct yourself mid-dictation) is part of Smart Formatting. With it off, spoken self-corrections are no longer removed.
Why trailing periods disappear
Punctuation stripping depends on the app and the text around your cursor, not on a writing-style setting.
When the text after your cursor continues the sentence (starts with a lowercase letter or with ! % , . : ; > ?), Flow strips a trailing period, exclamation mark, or question mark so you don't get doubled punctuation.
When you dictate over selected text, trailing punctuation is stripped unless the selection ended in a space.
FAQs
Do I need to turn anything on for mid-sentence blending to work?
It relies on Context Awareness, on by default on Mac and Windows under Settings → Data and Privacy. On Mac, Flow also needs Accessibility permission in System Settings; Windows has no equivalent requirement. Android has its own Context Awareness setting (on by default), and Flow's accessibility service must be enabled in system Settings → Accessibility for Flow to read surrounding text or insert into fields. If your organization has disabled Context Awareness, the toggle is off and locked.
Why does blending work better on Mac than Windows?
Windows accessibility support is more limited, so Flow reads less surrounding text and blending quality differs between the two platforms.
Why did Flow return unformatted text?
Flow returns raw text on very short input, an unsupported language, or when formatting takes too long. Blending quality also varies for non-English dictation.
Why is the first letter capitalized (or not) on iOS even with Smart Formatting off?
The iOS keyboard's auto-capitalization follows the text field's own setting: sentence fields capitalize after a period plus space, word fields after any whitespace, and username/email fields never do. It never overrides a Shift or caps lock you engaged yourself. This is separate from Smart Formatting, as are Autocorrect and the double-space-to-period shortcut, which apply only to text you type manually — never to dictated text.
Limitations and notes
Smart Formatting is available on Mac and Windows (Settings → System → Extras) and iOS (Settings → Personalization). On Android, formatting is always applied and there is no toggle.
The setting applies per device; there is no per-app or per-dictation override.
Context-aware formatting does not run in remote desktop sessions such as Citrix, RDP, or VMware; dictation pastes with default formatting there.
Flow never reads context from its own app window, so context-aware formatting is skipped when you dictate inside it.
On Android, Flow's bubble is hidden and context reads are skipped in banking and financial apps, so mid-sentence casing may not adapt there.
On Android, where Flow cannot trust the surrounding text — including password, phone, and numeric fields — it may place the dictation on your clipboard for you to paste manually, and the bubble is usually suppressed.
On Mac and Windows, Smart Formatting tips appear as notifications at most once every few hours.
In some apps, a space can go missing between your inserted dictation and the following text.
Very large text fields, very deeply nested UI, or slow-to-respond apps can yield no surrounding context, so blending falls back to new-sentence behavior.
On Mac, apps like Slack, Superhuman, and Notion may fall back to clipboard paste for text insertion.
On Android, TikTok, WeChat, and Xiaohongshu can fail focus detection entirely, leading to a clipboard fallback.
Notification-reply boxes (e.g. WhatsApp inline reply) are supported but use a different insertion path.
On iOS, undo immediately after a dictation insert reverts the inserted text and cursor position. Multi-line dictation into Notion on iOS is inserted line-by-line, so it may appear slower.
