FAQ & Help — FilsOnly

Step 1

Connect your inbox

How do I connect Gmail or Outlook?

Open FilsOnly and tap "Sign in with Google" or "Sign in with Microsoft" on the welcome screen. You'll be taken to your provider's real sign-in page — FilsOnly never sees your password, only a secure sign-in token.

Can I connect both Gmail and Outlook?

FilsOnly shows one inbox at a time. If you switch providers later (Settings → Disconnect), your previous provider's local data is cleared and you can connect the other one fresh.

Is my inbox stored anywhere?

The current app does not store your inbox in a general FilsOnly backend. Selected text is processed by AI services for features you use. Website beta requests and feedback are separate submissions stored through Netlify Forms. See our privacy policy for details and deletion requests.

Step 2

Add your AI key

FilsOnly runs on your own AI provider key — Anthropic (Claude) or OpenAI (GPT). You're billed directly by them, at cost, with no markup from FilsOnly. Here's how to get one, step by step.

Getting an API key

Anthropic (Claude)

Go to console.anthropic.com and sign in or create an account
Check the provider's current billing and usage settings before adding a payment method
Go to Settings → API Keys → Create Key
Name it something like "filsonly" so you recognize it later
Copy the key immediately — it's only shown once
Paste it into FilsOnly's Settings → API Key field, tap Save

OpenAI

Go to platform.openai.com and sign in or create an account
Review the current API billing options and set an appropriate usage limit
Go to Settings → API Keys → Create new secret key
Name it, then copy the key immediately — it's only shown once
Paste it into FilsOnly's Settings → API Key field, tap Save

Is it safe to paste my key into the app?

Yes — it's stored securely on your device (not sent to FilsOnly's servers) and used only to talk directly to your chosen AI provider.

What does this actually cost me?

The current FilsOnly beta has no FilsOnly subscription fee. If you use your own AI provider key, that provider bills your usage separately; the amount depends on your usage and its current rates. V2 is planned as a subscription, but pricing and early-access terms have not been finalized.

Step 3

It remembers what matters

How long does FilsOnly remember a thread?

Automatically, for 7 days — most follow-ups happen within a week.

What if I need to remember something older?

Tag the thread (the "Track" button, above the reply box, or from an email's options) to keep it remembered indefinitely, even after it's older than 7 days.

How do I untag something?

Go to the Closed tab and tap the "Tracked" pill on that message to remove it from tracking.

Step 4

Get nudged, not buried

How do nudges work?

FilsOnly checks periodically for threads that have gone quiet — where someone's waiting on your reply — and notifies you, even if the app is closed.

Why didn't I get a notification for something I expected?

A few common reasons: background sync may need to be turned on in Settings, the app needs a little time after install before its first real check runs, or (less commonly) the email may have landed in Spam/Junk on your provider's side rather than your main inbox — FilsOnly only sees what's in your Primary/Focused inbox.

Does this drain my battery?

Background checks are lightweight and infrequent — but if you'd rather not use this, you can turn Background Sync off in Settings any time.

Are Ask Fils and the two-way commitment ledger available now?

No. The current Android beta focuses on email triage, quiet-thread nudges and reply drafts. Ask Fils and the commitment ledger are in development for V2.
