Switch Labs is a product development studio — we design, build, and operate every product on this site ourselves. Our software also runs our own operations: Levy Electric's shared scooter fleets run on Levy Fleets and Switchboard in production.

How are AI features priced?

AI features are included in every plan at no additional cost. We don't charge per-token or add AI surcharges.

Yes, all our products come with robust REST APIs, webhooks, and SFTP integration options for enterprise workflows.

Where is data processed?

Most Switch Labs products are cloud-native, with data processed securely in US-based data centers with SOC 2 Type II compliance, AES-256 encryption, and full audit logging. ThreadPDF for Gmail is the exception — it processes your email entirely on your device, so nothing leaves your browser.

Can I try before I buy?

Yes, most of our products offer free trials or free tiers so you can evaluate before committing.

What kind of support do you offer?

We offer email support for all plans, with priority support and dedicated account managers for higher tiers.

How does Thread Pilot integrate with Gmail?

You connect one Gmail mailbox to Relay with Google sign-in, granting a single permission (gmail.modify). Thread Pilot watches that mailbox for messages you sent that never got a reply, and writes its follow-up as a draft in the original Gmail thread. It never sends anything on its own, and a real reply cancels the pending draft automatically.

What happens to emails I don't want to track?

Thread Pilot automatically excludes spam, trash, newsletters, and self-emails. You can also customize filters to exclude specific senders or email patterns. Only genuine conversations that need follow-up attention are tracked.

How does the AI generate follow-up messages?

Thread Pilot uses a sandboxed AI model to analyze your email thread's context, tone, and content. It generates contextually appropriate follow-up messages that match your communication style. You can review and edit all drafts before sending.

Can I customize when Thread Pilot runs?

Yes! You can schedule automated daily runs at your preferred time and set custom lookback periods (3, 5, 7+ days). You can also run Thread Pilot manually anytime with on-demand checks.

Will Thread Pilot create duplicate drafts?

No. Thread Pilot tracks which emails already have drafts and never creates duplicates. It's designed to keep your inbox organized without clutter.

Does it work with multiple Gmail accounts?

Each connection covers one Gmail mailbox, including its aliases and send-as addresses. Additional mailboxes are additional connections on a paid Relay plan.

How Thread Pilot compares

Boomerang, Streak, Mailtrack and Mixmax all touch follow-up in some way. None of them writes the message. Here is the honest breakdown against each.

Thread Pilot vs Boomerang
Boomerang schedules sends and sets reminders at the moment you write. Thread Pilot works retroactively on threads that already went cold.
Thread Pilot vs Streak
Streak is a CRM inside Gmail with a pipeline to configure. Thread Pilot solves one narrow problem and needs no setup.
Thread Pilot vs Mailtrack
Mailtrack tells you an email was opened and ignored. Thread Pilot drafts the message that follows it.
Thread Pilot vs Mixmax
Mixmax fires automated outbound sequences. Thread Pilot only ever writes a draft, and you decide what sends.
