Thoughts worth keeping todayProduct concept · illustrative content
Your scattered thoughts begin to connect.
Perhaps it starts with one quiet walking route.
“People want to walk more, but do not know where to go. What about a small product that suggests a quiet route each day?”

“A route you can finish in ten minutes might matter most. No planning needed. Just step outside.”

Good ideas often arrive
when you are doing something else.
On a walk, between errands, or just after a shower. Say it while it is fresh and carry on with your day. Return later to a thought you can still develop.
Between things
“Wait, there is another way to approach that idea.”
Open your phone and add the new clue.
At the end of the day
“These separate thoughts are about the same thing.”
Revisit what matters and decide what to continue.
When a thought arrives,
say it on your phone.
One deliberate recording is enough. Start when you have something to say and stop when you are done.

Frequently Asked Questions
Do I need to download a transcription model?
No manual model selection or download is required. SpeakPen first tries available local transcription and uses the cloud if it cannot run. Audio and text sync to your account; offline recordings are saved for later processing.
What is SpeakPen?
SpeakPen turns your recordings into text and summaries you can revisit, search, and organize. You can use it on its own. If you use Obsidian or an AI assistant, connect them when you need them.
How does the voice-to-text transcription work?
After you record or import audio, SpeakPen processes it into text and a summary. Automatic language detection supports 99 languages.
Can SpeakPen sync with Obsidian?
Yes. Install "SpeakPen Sync" from Obsidian's community plugin browser, then paste an API token — generate one in the SpeakPen web app at speakpen.app/app, under Settings → Connections (Obsidian card → Generate token). New notes then arrive in your vault as Markdown, each with a title, summary, and full transcript.
How is SpeakPen different from Obsidian Quick Capture and other voice apps?
Obsidian's own Quick Capture and most inbox apps are built for a typed line. Voice plugins for Obsidian only record while Obsidian is open, and Mac transcription apps need your Mac. SpeakPen is for the ideas you would rather talk through: it records on your phone or in a browser, lets you pause and ramble, detects the language, and syncs a titled, summarized Markdown note into your vault afterwards.
What languages does SpeakPen support?
Automatic language detection covers 99 languages — just speak and SpeakPen figures it out. If you prefer to pin a language manually instead of relying on detection, the manual picker currently offers 10: English, Chinese (Simplified and Traditional), Japanese, Korean, Spanish, French, German, Portuguese, and Italian.
Is SpeakPen free to use?
SpeakPen offers a free plan with 3 recordings (up to 5 minutes each) so you can experience the full pipeline. The Pro plan at $9.99/month unlocks 60 recordings per month with up to 20 minutes each.
Can I import existing audio files?
Yes, SpeakPen supports importing audio files in addition to recording directly. Imported audio goes through the same AI transcription and summary pipeline as live recordings.
Do I need Claude or Codex for this to be useful?
No. Transcription, summaries, action items, rewriting, and asking questions across your notes all happen inside SpeakPen. The agent step exists because your notes are plain Markdown in a folder you control — anything you already point at that folder can read them, so nothing has to be integrated on our side.
