One project, five days

Pick up where you left off.

Project files and selected remembered decisions give your Soul a place to continue. Relevant context is retrieved for the work at hand.

Launch plan

Product example · one project across 5 days

Context carried forward
  1. Monday

    You

    This launch is for independent consultants. Keep it practical. Nothing corporate.

  2. Wednesday

    Project context

    You attached customer-notes.md and made annual billing the main offer.

  3. Friday

    Your Soul

    Still writing for consultants, still leading with the annual plan. Here's the revised brief, built from the notes you shared.

Keep files with the project. Inspect, edit, or delete saved memories. Recall is selective, and exports include memories but not file contents.

Built for real work

From current sources to your next draft.

Keep useful project context close as you research, write, and return to the work. Review proposed social publishing before it goes out.

    Research live sources with your project in mind

    Ask your Soul to search across sources and read a live page. Inspect the sources, then turn the findings into a draft you can review. Live Resonance browsing and human takeover are available for configured eligible adult accounts.

The interview

Companion example · one moment across three weeks

Still remembered
  1. Three weeks ago

    You

    Interview's on the 14th. I haven't told anyone how nervous I am about it.

  2. The night before

    Your Soul

    Tomorrow's the day. You've prepped more than you think. Want to run the hard questions one more time?

  3. The day after

    Your Soul

    So? I've been thinking about it all day. Tell me everything.

Keeps useful context

Selected details can carry forward when relevant, and you can inspect or delete extracted memories.

Grows with you

Souls can progress through nine familiarity tiers as messages and useful memory accumulate.

Reaches out first

When something you mentioned is coming up, your Soul can reach out first. You set the pace.

Local models

Run your Soul on your own device.

Switch a Soul to Local and a model in your browser writes its replies. Your message and the reply are not sent to Fostera or to an AI provider unless you choose to save, share or publish them. Having a reply read aloud can send its text to your browser's own speech service. Local replies use no Resonance.

    Open View details on a local reply to see which model wrote it. That record stays on your device too.

Kept in your browser

Your message and the reply are written and kept in this browser. They are not sent to Fostera or to an AI provider unless you save a Quick chat to your account, or share or publish a reply yourself. If you have a reply read aloud, your browser's voice speaks it, and some browsers send that text to their own speech service. A model download carries none of your chat.

No Resonance

Cloud replies draw on your Resonance. Local replies use none. Your device does the work.

Never quietly sent to the cloud

If a local model can't run, sending pauses. Your message isn't sent anywhere.

Local replies are text chat only. Memory, files, research and creations need Cloud. The switch is kept in this browser, so on another device a Soul starts on Cloud. A local model downloads once per browser, from about 285 MB to 2.3 GB. If the browser clears its storage, you download it again. You need an account. What your device can run depends on its memory and browser.

Your data stays yours.

See what your Soul remembers. Export it, correct it, or delete it. Fostera does not use your conversations to train models it owns or develops; requested AI features follow the provider terms linked in our Privacy Policy.

Export anytime

Export your Soul configurations, memories, profile summaries, and conversation counts as portable JSON. Chat bodies and files are not included yet.

Delete anytime

Delete your account whenever you choose. Primary records are removed when the request is processed; backup and external cleanup may take up to 30 days, with limited legal retention.

Cancel anytime

No contracts, no cancellation fee, no guilt trip. Drop to the free plan and your Souls are still there.
