A second brain, in the usual sense, is a personal knowledge system. Notes, links, highlights and files, organised so you can find them again.
That is a filing problem, and good tools solve it. Your own recurring thoughts are a different problem. They do not need retrieval. They need to be seen.
Storage versus reflection
Knowledge tools ask you to capture, organise and retrieve. Every step is work you do. The system holds what you put in and returns exactly that when asked.
absorvia asks for the capture only. With AI enabled and an available allowance, it can return one line, the Echo. It reads across thoughts and returns the pattern. The system does the noticing, and nothing needs organising.
What a thinking system surfaces
Depth is the daily surface. Today's Pulse is one sentence about yesterday. Active Signals show what you keep circling. Today's Pattern names the thread running through recent captures.
Undercurrent is the long layer. It reveals tensions, shifts and identity changes across weeks, starting with simple signals and deepening as the record grows.
- No folders, tags, links or templates.
- No search, because nothing is filed. The pattern comes to you.
- Sit With It, in Premium, revisits any thought with a contextual prompt and one or two related Echoes from your history.
Use both
If you run a knowledge system, keep it. It is where reference material belongs. absorvia is for the thoughts that are not reference material: the worry you have written forty ways, the decision you keep circling, the thing you notice about yourself and forget.
Private by construction
Your thought library stays on your device. Optional iCloud backup, off by default, keeps a copy in your own iCloud that absorvia cannot read. No absorvia account is required. AI reflections are opt-in. With your permission, relevant writing and context are sent to our backend and, when needed, to OpenAI. A request can include excerpts from more than one capture. This text is not used to train OpenAI's models. Switch AI Reflections off in Settings to stop future AI requests. Temporary service records are explained in the privacy policy.
Cost
absorvia is free to start. The free plan includes up to five saved thoughts per day and basic writing patterns. Premium includes up to 100 saved thoughts per day, voice capture, daily depth, deeper pattern surfacing and Sit With It. Monthly and annual subscriptions renew automatically. Eligible subscribers can try the annual plan free for 7 days. Current prices and eligibility are shown at purchase. AI reflections require your permission and an internet connection. The free plan includes up to three AI reflections in a rolling seven-day period. A reflection is an optional written response to a thought; the on-device thought category and orb colour do not require one. Premium includes further access subject to fair-use limits. You can keep writing within your plan’s capture allowance when reflections are unavailable.
Questions
Is absorvia a second brain app?
Not in the knowledge-management sense. It does not store files, links or highlights, and there is nothing to organise. It reflects on the thoughts you write and shows patterns across them.
Can I import my notes?
No. absorvia is for new thoughts, written in the moment. Reflection works on what you capture, not on an archive.
Can I export my thoughts?
Yes. Export Thoughts is in Settings, and Delete All Data is beside it. Your library is yours.
Does it sync between devices?
There is no journal sync between devices. Your writing library is stored locally on your iPhone or iPad.
Try it. Write one thought and see what comes back.
