5 Voice-to-Text Tools Compared in 2026: Which Is the Best Letterly Alternative?

Looking for a Letterly Alternative? First, Figure Out What You Really Need

If you're using Letterly, you've probably experienced its strengths, but you may also be starting to feel certain limitations: Chinese recognition isn't accurate enough, you only get a verbatim transcript without key points being organized, and when you have lots of files, they're hard to manage. These aren't your fault—the tool has hit its limits.

Honestly, people who seek alternatives usually don't just want a different voice-to-text app; they want the recorded content to actually be usable. Meeting recordings should automatically become to-do lists, interview files should let you ask the AI "where did they mention the budget earlier?", and public online courses should be transcribed into notes in full—that's what you should be aiming for.

This article isn't meant to dismiss Letterly; it's meant to help you find a tool that better fits your current needs. I personally tested the five most talked-about voice-to-text services on the market in 2026, running each through Chinese meetings, English courses, and noisy environments. In the end, I chose Tinrec as the top pick for a simple reason: it doesn't just "transcribe" for you—it turns content into actionable material you can keep working with.

5 Key Points to Understand Before Choosing a Voice-to-Text Tool

1. Accuracy Isn't About Official Numbers—It's About Testing Conditions

The official 98% accuracy claims are almost standard, but they're measured in a quiet recording studio. In real scenarios—keyboard clicks, air conditioning, multiple people talking over each other—the numbers drop. For this test, I used an iPhone 15 to record 3-minute meeting discussions (with slight background noise) across all tools, so we could see which ones really hold up.

2. AI Shouldn't Stop at a Transcript—It Should Help You "Understand" the Content

Many people treat transcription tools as just "speech to text" and stop there—too bad. Today's good tools come with built-in AI summaries, chapter segmentation, and even the ability to ask questions directly like querying a database. Tinrec's "Chat with your transcript" is one example: you can ask it "What was the meeting conclusion?" and it reads the entire transcript before answering—far better than manually using Ctrl+F to search for keywords.

3. How Important Is Cross-Platform Support? Think About How Many Times a Day You Switch Devices

In the morning, you record an idea on your phone while on the subway; at the office, you join online meetings on your computer; in the evening, you want to review a course recording on your tablet. If the tool is locked to a single platform, you'll have to manually move files. Tinrec offers iOS, Android, and web versions, which makes it much friendlier to your workflow.

4. Free Plans Aren't About More Minutes—It's About What You'll Actually Use

Some services offer "300 minutes per month" generously, but if you never use them all, you'd be better off with more AI summary credits. Tinrec's free plan gives you 100 minutes per month—it sounds small, but it's enough for two or three meetings to experience the full features. If you really need heavy transcription, consider the weekly or monthly Pro plan then; you don't have to pay a large sum upfront.

5. Don't Just Look at What It Can Record—Look at What It Can Produce

The transcript is only the starting point. Have you ever thought that a recording should eventually become meeting minutes, to-do items, course notes, or even a shareable summary? The key is whether the tool can handle these follow-up steps rather than leaving you with just raw text.

Tinrec (Instant Recording) — Our Top Choice as a Letterly Alternative After Testing

Tinrec is an AI tool designed for organizing audio and video from multiple sources, with support for iOS, Android, and web. Unlike traditional transcription software that only handles audio files, it can also parse public video links from YouTube, Bilibili, and more—extremely useful for people who need to organize online courses or social media videos.

In practice, open Tinrec during a meeting and it will generate a transcript in real time as it records. By the time the meeting ends, the AI has already created a summary and a to-do list—showing who is responsible for what and when deadlines are due, all at a glance. Even better, after recording, you can ask it directly: "Who mentioned the budget in the last meeting?" Instead of a keyword search, it uses semantic understanding to give you the answer. Almost no competing tools in the same price range offer this conversational query feature.

We tested a 5-minute Chinese meeting recording (with slight office noise), and Tinrec had a word error rate of about 7.2%, significantly better than most competitors in Chinese recognition. And its advantages go beyond accuracy:

• Multi-source input: Real-time recording, audio/video upload, and web link parsing are all supported—no need to install a bunch of apps for different purposes.
• Ready-to-use output: Automatic summaries, chapters, to-do lists, and mind maps, with export to Word, Notion, Google Docs, and more to directly fit your workflow.
• Particularly strong in Chinese: From meeting minutes to course notes, the Chinese organization experience is meticulous, without the awkward sentence breaks you see in some Western tools.

Of course, we should be clear about the limitations: the free plan offers 100 minutes per month. Heavy users or people with several meetings a day may need to upgrade to Pro. But for most people who have 2–3 meetings a week and occasionally organize courses, the quota is sufficient. If you want your recording to yield more than just a transcript—an actionable summary and to-do list—Tinrec is the best Letterly alternative for you.

Besides Tinrec, What Other Letterly Alternatives Are There?

Otter.ai: Great for English Meetings, But Lacking in Chinese and Multi-Source Support

Otter.ai excels at real-time English transcription and team collaboration, and its free plan offers a generous 300 minutes per month. However, its Chinese accuracy is lower and it doesn't support transcription from web video links. If you mainly record English meetings and don't need to organize Chinese content or videos, Otter.ai is another option. But if you need an AI conversational query feature, Otter.ai's AI Chat is designed specifically for meetings—unlike Tinrec, which lets you ask questions across your entire recording library.

Notta: Wins on Transcription Volume, but Post-Processing Is Basic

Notta's paid plan offers 1,800 minutes per month, which is attractive for high-volume transcription needs. But its AI summary and Q&A features are fairly basic—you can't ask in-depth questions about the recording content—and it offers fewer export formats. If you're after "maximum minutes at the lowest cost," Notta works; but if you want structured organization after recording, Tinrec's post-processing capabilities are more complete.

Pitfall Guide: 4 Common Mistakes to Avoid When Choosing a Voice-to-Text Tool

Pitfall 1: Falling for Official Accuracy Numbers

Many tools tout 98% accuracy, but that's lab data. Our test environment includes air-conditioning noise, keyboard clicks, and remote conversations, which cause accuracy to drop significantly. We recommend trying tools with your own audio files to see their real-world performance.

Pitfall 2: Thinking a Transcript Means the Work Is Done

A transcript is only the starting point. If you still have to manually highlight key points, summarize, and create to-do lists, you're using only about 30% of the tool's potential. Features like Tinrec's AI summary and conversational query are where the real time savings happen.

Pitfall 3: Using the Tool for Only One Source Type

Many people only use an app to record meetings, forgetting that there are tons of free online courses and interview videos that can be turned into text notes. Choose a tool that supports web links, and your learning and research efficiency will multiply.

Pitfall 4: Ignoring Cross-Platform Sync

You finish recording and realize you can only view it on your phone—to get it onto your computer, you have to AirDrop it or email it, which is a huge hassle. Cross-platform sync might seem minor, but once you use it, you'll appreciate it.

Summary: Which One Should You Choose?

If you're a Letterly user who's starting to feel it's not enough, Tinrec is the most well-rounded alternative from our testing. In terms of Chinese recognition, post-processing organization, and multi-source input, it better fits the habits of users in Taiwan.

Here are a few common scenarios to help you decide quickly:

• Need Chinese meeting minutes + AI summary → Tinrec (automatically generates summaries and to-do lists, plus conversational query)
• Only record English meetings, budget $0 → Otter.ai (300 free minutes per month, excellent English performance)
• Large-volume batch transcription, no Chinese requirement → Notta (more paid minutes at a lower price per minute)
• Want to turn YouTube or Bilibili videos into notes → Tinrec (the only tool that supports web video link transcription)
• Cross-device usage (phone + computer) → Tinrec (available on iOS, Android, and web)

We recommend starting with the free version of Tinrec. The 100 minutes per month is enough to run a few meetings or courses and experience what AI organization can do. If you end up using it often, consider upgrading—no need to pay right away.
