Canary features and specs

  • All-in-One System
    Canary combines multiple devices, such as a camera, microphone, siren, and environmental sensors, into one compact unit, reducing clutter and simplifying setup.
  • Simple Setup
    The device offers easy installation with no professional help required, making it user-friendly even for those not tech-savvy.
  • HD Quality and Night Vision
    Canary provides high-definition video recording and clear night vision, ensuring quality surveillance at all hours.

    In addition to video surveillance, Canary monitors air quality, temperature, and humidity, offering a more comprehensive view of your home's environment.
  • Two-Way Audio
    The system includes a two-way audio feature, allowing users to communicate with people or pets at home remotely.
  • Smart Alerts
    Canary sends intelligent notifications based on detected activity, allowing users to stay informed without checking live feeds constantly.
  • Integration with Smart Home Devices
    Canary integrates well with other smart home devices and platforms like Google Assistant and Amazon Alexa, facilitating a cohesive smart home ecosystem.

Possible disadvantages of Canary

  • Subscription Costs
    While basic features are available out of the box, advanced features and extended video history require a subscription, which could be a drawback for budget-conscious users.
  • Privacy Concerns
    As with any internet-connected camera, there are potential privacy risks, such as hacking, which may concern some users.
  • Limited Free Cloud Storage
    Free users have limited access to cloud storage, which means that without a subscription, storing and reviewing past footage is restricted.
  • Dependence on Wi-Fi
    Canary devices rely on a strong and stable Wi-Fi connection. Poor connectivity can affect performance, such as delayed notifications or reduced video quality.
  • No Local Storage Option
    The absence of local storage options means users fully depend on cloud storage for video footage, which can be limiting for those wanting immediate and constant access to their recordings.

Questions & Answers

As answered by people managing Canary and ForthWrite.

Which are the primary technologies used for building your product?

ForthWrite's answer:

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

What makes your product unique?

ForthWrite's answer:

ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.

Why should a person choose your product over its competitors?

ForthWrite's answer:

Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.

How would you describe the primary audience of your product?

ForthWrite's answer:

Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.

What's the story behind your product?

ForthWrite's answer:

Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.

    I built ForthWrite to fix generic AI email, and I still use it every day

    I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.

    The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.

    What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.

    The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.

    Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.

    ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.

    Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.

    ๐Ÿ Competitors: Jace.ai, Fyxer, Mailmeteor
    ๐Ÿ‘ Pros:    Drafts land inside gmail and outlook; no copy-pasting from a chat window|Voice matching is on the free tier, not paywalled behind paid plans|No api key, no credit card to start; free tier runs on a server-side proxy|Learns from every edit you make before sending; drafts improve over time|Full keyboard flow: alt+shift+d to draft in any thread, no mouse required|Byok on paid plans, 9 providers supported, keys encrypted at rest|Web compose at forthwrite.ai works without installing the extension at all
    ๐Ÿ‘Ž Cons:    10 free drafts/week is enough to evaluate, not enough for a heavy inbox|Auto-draft, batch replies, and prompt lab all require the pro tier|Early-stage product; fewer third-party integrations than mature inbox tools|No mobile app: the extension and add-in are desktop-only (chrome on web, or the outlook desktop add-in)

  • Looking for interior security, without a camera
    Not HomeKit compatible and it contains some stuff you don't want, but there's an all in one smoke / CO camera/mic/speaker with integrated siren product called "Canary" that's about the size of a 16 oz energy drink can that might be a potential once in a while away for the weekend solution. https://canary.is.

  • Sense Premium Subscription (kidding...)
    Some other IOT companies (canary.is) have been forced to move free features to a subscription model so the business says solvent. Could Sense do something similar? Source: about 5 years ago
