AI countdown timer generator: describe the sale, get the timer

The AI writes a complete timer, not a suggestion you have to rebuild. From your description it sets the name, how long the countdown runs, the layout (one of six: pill, boxes, circles, compact, minimal or rings), the size, and every color: background, digits, digit blocks and their borders, labels and separators. It decides whether to show days, labels and separators, and writes the expiry message readers see once the sale is over.

Some things it only sets when you ask, so it never guesses. Name a font ("use Playfair Display") and it uses that font if it is in your library, unless your brand kit sets a font, which comes first. Ask for French or Spanish and the labels switch language. Ask for a transparent background and it removes the backdrop and sets the email background color the GIF's edges blend into. Leave the duration out and it defaults to 3 days.

• Name and internal note
• Countdown length in minutes, hours, days or weeks
• Layout, size and full color palette
• Expiry message copy
• Font, language and transparent background, when you ask for them

Short prompts work. Mood words (urgent, calm, luxury, playful) steer colors and copy; numbers steer the deadline.

• "Black Friday sale ending in 3 days, red and black, urgent tone": a 3-day countdown on a dark background with red accents and a short, urgent expiry message.
• "Spring collection launch, 1 week, soft pastels, Playfair Display font": a 7-day timer in pastel tones set in Playfair Display, ready for a product launch email.
• "24-hour flash sale in French, transparent, sits on a navy banner": a 24-hour timer with French labels (JOURS, HEURES, MINUTES, SECONDES), no backdrop and edges blended for navy.
• "Cyber Monday, 12 hours, neon gaming style, hide the days": a 12-hour countdown with bright digits on a dark background and the days unit hidden.
• Logo attached, prompt "Welcome offer, 7 days": a 7-day timer in your logo's colors for a welcome discount email.

If you have saved a brand kit (primary, secondary and accent colors, plus a font) under Brand Kit in the sidebar, Create with AI in the dashboard uses it exactly: your primary color as the background, your secondary color for the digit blocks and your accent color for the digits and labels. The AI still chooses the layout, size and copy, but your hex codes are never approximated.

No brand kit yet? Attach your logo to the prompt. The AI reads its dominant colors and builds the palette from them, aiming to keep the digits readable against their background, so check the contrast in the preview. The logo is used for that one request and isn't stored.

The same AI edits timers you already have. Open a timer in the editor, ask for a change, and it returns the whole timer with only that change applied: "make it red" changes colors, not your copy or your deadline. The end date only moves when you explicitly ask to reschedule, such as "end it next Friday". In the editor a revision arrives as unsaved changes, so you see it in the preview and check the date before you save.

From an MCP client, revise_timer never moves the schedule of a timer without a single end date. An evergreen, recurring, cycle, count-up or personalized countdown timer can be restyled and rewritten, and the reply says so if you asked for a new end date.

On Pro and up, flashtimer runs an MCP server, so AI assistants can work with your timers from the chat you already use. In Claude and Grok, add it as a custom connector; in ChatGPT, as a custom MCP server; in Gemini, as a custom app. Either way you sign in to flashtimer and choose the organization, with no key to copy, and the guide to flashtimer in AI assistants has the steps for each app. Then ask: "Create a flashtimer for our 48-hour members' sale, dark green and gold" or "List my timers ending this week and archive the Easter one".

Designing a timer from a brief and revising it use the same AI as Create with AI in the dashboard and share its daily allowance. The assistant can also create, change, copy, archive and delete timers, make them from your store's discounts, read their analytics, check your usage, and put a timer into a draft or scheduled campaign on a connected email platform once you confirm a preview. On Business it runs A/B tests and expires a timer when a product sells out. It can set up any timer type with exact settings, including recurring, cycle, count-up, evergreen and dynamic, so a daily 2pm cut-off is one request.

VS Code, the OpenAI API and other clients that take a fixed header connect with an API token instead, as the developer docs show. The MCP server shares the rate limit of the countdown timer API.
