Description
Live token count, cost estimate and context usage shown inline while you chat with popular AI assistants. Free. tokcount is a live token, cost, and context-window meter for popular AI chat surfaces. As you type in the composer, a small overlay in the corner shows: • tokens — estimated locally via per-family tokenizer heuristics plus language multipliers for non-latin scripts • cost — input-token dollar estimate at the current model's per-1M input rate • context % — how much of the model's context window you've already committed to the prompt It activates only on supported AI chat domains. The full list of currently supported domains, with screenshots, lives at voiddo.com/tools/tokcount/ — we update it whenever a new surface ships. WHY USE IT • Stop writing five paragraphs into a chat and only then realizing you blew past the context window — the bar turns red at 85% • Stop eyeballing "how expensive is this prompt, actually" — it shows dollars, not abstract token counts • 30-day usage dashboard by model and project, CSV export (Pro) • Daily / weekly / monthly budget guards with optional hard-stop (Pro) FREE FOREVER • Overlay on every supported platform • 7-day local history, 200 recent measurements • Accurate cost math for the 30+ most-used models • Pricing refreshed from a public manifest every hour — when vendors cut prices, your extension updates the same day (no reinstall) PRO — $4.99/mo • 10-year history, unlimited entries, 50 saved projects • Budget guards with hard-stop (prompt blocked when over-budget) • CSV export + cache-hit detector • Higher-accuracy tokenizer overrides per model family • Custom model definitions (bring your own model cost row) Team and Enterprise tiers available at voiddo.com/tools/tokcount/upgrade. PRIVACY tokcount does not read your prompts after you send them. It counts characters in the composer before you hit send, converts locally, and writes nothing but aggregate daily totals to browser-local storage. The only outbound requests are: (1) a once-per-hour pull of the public pricing manifest (voiddo.com/tools/tokcount/pricing.json — no cookies, no body) (2) a once-per-day license revalidation IF you've entered a Pro key No analytics.
