A voice-first home for ideas

Hold. Speak. Keep the spark.

SparkThread is an invite-only Android Alpha for early users in the EU and US. Speak a thought, keep it as a Spark, and grow related Sparks into a source-linked Big Thought.

Access is invite-only. Apply, then wait for an owner-issued code. No open signup. The iOS beta is available through TestFlight.

One button removes the distance between thinking and keeping.

Speak first. Organize only when you are ready. SparkThread preserves the thread from the original Spark to every Big Thought it helps form.

  1. Capture instantly

    Hold the recording button from anywhere in the app and speak naturally.

  2. Confirm the thread

    Review the transcription and decide which personal tags fit.

  3. Grow a Big Thought

    Related confirmed Sparks are refined into a source-linked idea over time.

More personal with every use. Ready for AI agents.

Voice without ceremony

No title, folder, or perfect sentence is required before you press the button.

It learns the way you think

Every tag you confirm and every Spark you connect sharpens your personal context. You can review and correct it at any time.

Big Thoughts can become agent work

A planned Codex connection will turn a confirmed idea into a development task and bring the result back to SparkThread. Not available yet.

Notes need threads, not folders

A folder stores where a note was placed. A thread remembers how one thought became another.

Why SparkThread waits before it speaks

Useful thinking needs assistance, but it also needs quiet, correction, and a visible trail back to the source.
